A 38-year-old retired NASA satellite is about to fall from the sky.

NASA said Friday the chance of wreckage falling on anybody is “very low.” Most of the 5,400-pound (2,450-kilogram) satellite will burn up upon reentry, according to NASA. But some pieces are expected to survive.

The space agency put the odds of injury from falling debris at about 1-in-9,400.

The science satellite is expected to come down Sunday night, give or take 17 hours, according to the Defense Department.

The California-based Aerospace Corp., however, is targeting Monday morning, give or take 13 hours, along a track passing over Africa, Asia the Middle East and the westernmost areas of North and South America.

The Earth Radiation Budget Satellite, known as ERBS, was launched in 1984 aboard the space shuttle Challenger. Although its expected working lifetime was two years, the satellite kept making ozone and other atmospheric measurements until its retirement in 2005. The satellite studied how Earth absorbed and radiated energy from the sun.

The satellite got a special send-off from Challenger. America’s first woman in space, Sally Ride, released the satellite into orbit using the shuttle’s robot arm. That same mission also featured the first spacewalk by a U.S. woman: Kathryn Sullivan. It was the first time two female astronauts flew in space together.

It was the second and final spaceflight for Ride, who died in 2012.

 U.S. health officials on Friday approved a closely watched Alzheimer’s drug that’s been shown to modestly slow the early stages of the brain-robbing disease, albeit with potential safety risks that doctors and patients will have to weigh carefully.

The drug, Leqembi, is the first that’s been convincingly shown to slow the decline in memory and thinking that defines Alzheimer’s by targeting the disease’s underlying biology. The Food and Drug Administration approved it specifically for patients with mild or early cases of dementia.

An uncommon success

Leqembi, from Japan’s Eisai and its U.S. partner Biogen, is a rare success in a field accustomed to failed experimental treatments for the incurable condition. The delay in cognitive decline brought about by the drug likely amounts to just several months, but some experts say it could still meaningfully improve people’s lives.

“This drug is not a cure. It doesn’t stop people from getting worse, but it does measurably slow the progression of the disease,” said Dr. Joy Snider, a neurologist at Washington University in St. Louis. “That might mean someone could have an extra six months to a year of being able to drive.”

Snider stressed that the medicine, pronounced “leh-KEM-bee,” comes with downsides, including the need for twice-a-month infusions and possible side effects such as brain swelling and bleeding.

Approval came via FDA’s accelerated pathway, which allows drugs to launch based on early results, before they’re confirmed to benefit patients. The agency’s use of that shortcut has come under increasing scrutiny from government watchdogs and congressional investigators.

Last week, a congressional report found that the FDA’s approval of a similar Alzheimer’s drug called Aduhelm — also from Biogen and Eisai — was “rife with irregularities,” including a number of meetings with drug company staffers that went undocumented.

Average price tag: $26,500 a year

Scrutiny of the new drug, known chemically as lecanemab, will likely mean most patients won’t start receiving it for months, as insurers decide whether to cover it and for whom.

The drug will cost $26,500 for a typical year’s worth of treatment. Eisai said that price reflects the drug’s benefit in terms of improved quality of life, reduced burdens for caregivers and other factors. The company pegged its overall value at $37,000 per year, but said it priced the drug lower to reduce costs for patients and insurers. An independent group that assesses drug value recently said the drug would have to be priced below $20,600 to be cost-effective.

Some 6 million people in the U.S. and many more worldwide have Alzheimer’s, which gradually attacks areas of the brain needed for memory, reasoning, communication and daily tasks.

The FDA’s approval was based on one mid-stage study in 850 people with early symptoms of Alzheimer’s who also tested positive for a type of brain plaque that is a hallmark of the disease.

Since then, Eisai has published the results of a larger 1,800-patient study that the FDA is expected to soon review to confirm the drug’s benefit, setting up a decision on full approval later this year.

The larger study tracked patients’ results on an 18-point scale that measures memory, judgment and other cognitive abilities. Doctors compile the rating from interviews with the patient and a close contact. After 18 months, patients receiving Leqembi declined more slowly — a difference of less than half a point on the scale — than patients who received a dummy infusion. The delay amounted to just over five months.

There is little consensus on whether that difference translates into real benefits for patients, such as greater independence.

“Most patients won’t notice the difference,” said Dr. Matthew Schrag, a neurology researcher at Vanderbilt University. “This is really quite a small effect and probably below the threshold of what we’d call clinically significant.”

Schrag and some other researchers believe a meaningful improvement would require at least a difference of one full point on the 18-point scale.

Leqembi works by clearing a sticky brain protein called amyloid that’s a key indicator of Alzheimer’s. But it’s not clear exactly what causes the disease. A string of other amyloid-targeting drugs have failed, and many researchers now think combination treatments will be needed.

Aduhelm, the similar drug, was marred by controversy over its effectiveness.

The FDA approved that drug in 2021 against the advice of the agency’s own outside experts. Doctors hesitated to prescribe the drug, and insurers restricted coverage.

The FDA did not consult the same expert panel before approving Leqembi.

Rep. Rosa DeLauro of Connecticut — a frequent FDA critic — said in a statement Friday that she was “deeply concerned that FDA chose to forego” a panel meeting on the drug.

Schrag said many of the same concerns apply to both drugs.

“Is this slight, measurable benefit worth the hefty price tag and the side effects patients may experience?” she asked. “I have pretty serious doubts.”

About 13% of patients in Eisai’s study had swelling of the brain and 17% had small brain bleeds, side effects seen with earlier amyloid-targeting medications. In most cases those problems didn’t cause symptoms, which can include dizziness and vision problems.

Also, several Leqembi users died while taking the drug, including two who were on blood-thinning medications. Eisai has said the deaths can’t be attributed to the drug. The FDA label warns doctors to use caution if they prescribe Leqembi to patients on blood thinners.

Insurers are likely to cover the drug only for people like those in the company study — patients with mild dementia and confirmation of amyloid buildup. That typically requires expensive brain scans or a spinal fluid test. Doctors will need to perform a different type of scan to periodically check for brain swelling and bleeding.

Medicare coverage still up in air

A key question in the drug’s rollout will be insurance coverage by Medicare, the federal health plan that covers 60 million seniors and other Americans. The agency severely restricted coverage of Aduhelm, essentially wiping out its U.S. market and prompting Biogen to abandon marketing plans for the drug.

Eisai executives said they have already spent months discussing their drug’s data with Medicare officials. Coverage isn’t expected until after the FDA confirms the drug’s benefit, expected later this year.

“Once we have a Medicare decision, then we can truly launch the drug across the country,” said Eisai’s U.S. CEO, Ivan Cheung.

Betsy Groves, 73, was diagnosed with Alzheimer’s in 2021. A former lecturer at Harvard’s graduate school of education, she noticed she was having trouble remembering some students’ names and answering questions.

Her initial diagnosis, based on a cognitive examination, was later confirmed by a positive test for amyloid.

Groves, of Cambridge, Massachusetts, says she is “more than willing” to try Leqembi, despite potential side effects and the need for infusions.

“For me, the minute that drug comes on the market — and I get my doctor’s approval — I’m going to take it,” Groves said.

The Biden administration is proposing tougher standards for a deadly air pollutant, saying that reducing soot from tailpipes, smokestacks and wildfires could prevent thousands of premature deaths a year. 

A proposal released Friday by the Environmental Protection Agency would set maximum levels of 9 to 10 micrograms of fine particle pollution per cubic meter of air, down from 12 micrograms set a decade ago under the Obama administration. The standard for particle pollution, more commonly known as soot, was left unchanged by former President Donald Trump, who overrode a scientific recommendation for a lower standard in his final days in office. 

Environmental and public health groups that have been pushing for a stronger standard were disappointed, saying the EPA proposal does not go far enough to limit emissions of what is broadly called “fine particulate matter,” the tiny bits of soot we breathe in unseen from tailpipes, wildfires, factory and power plant smokestacks, and other sources. 

In a development that could lead to an even lower standard, the EPA said Friday that it also would take comments on a range of ideas submitted by a scientific advisory committee, including a proposal that would lower the maximum standard for soot to 8 micrograms. A microgram is one-millionth of a gram. 

EPA Administrator Michael Regan said the proposal to strengthen the national ambient air quality standards for fine particle pollution would help prevent serious health problems, including asthma attacks, heart attacks and premature death that disproportionately affect vulnerable populations. Those populations include children, older adults and those with heart and lung conditions, as well as low-income and minority communities throughout the United States. 

“This administration is committed to working to ensure that all people, regardless of the color of their skin, the community they live in or the money in their pocket, have clean air to breathe, clean water to drink and the opportunity to lead a healthy life,” Regan said at a news conference. “At EPA, we are working every single day to create cleaner and healthier communities for all and have been doing so for over 50 years.” 

‘A disappointment’

Harold Wimmer, the president of the American Lung Association, called the EPA’s proposal disappointing, saying it was “inadequate to protect public health from this deadly pollutant.” 

“Current science shows that stronger limits are urgently needed … to protect vulnerable populations,” Wimmer said, calling for the EPA to lower the standard to 8 micrograms or lower. 

Seth Johnson, an attorney for the environmental group Earthjustice, called the EPA plan “a disappointment and missed opportunity overall.” While it would strengthen some public health protections, “EPA is not living up to the ambitions of this administration to follow the science, protect public health and advance environmental justice,” Johnson said. He urged the EPA “to hear communities, not industrial polluters, and strengthen this rule. Overburdened communities have the right to breathe clean air.” 

The U.S. Chamber of Commerce and other business groups called for the current standards to be maintained. 

“The United States has some of the best air quality in the world, thanks to steady reductions in contributors to particulate matter emissions over the last decade,” said Chad Whiteman, vice president of environment and regulatory affairs at the chamber’s Global Energy Institute. 

The proposed rule could “stifle manufacturing and industrial investment and exacerbate permitting challenges that continue to hamper the economy,” Whiteman said. 

‘Regulatory burden’

Mike Ireland, president of the Portland Cement Association, which represents U.S. cement manufacturers, added that the EPA’s proposed action “is yet another regulatory burden that will hamper the cement industry’s ability to manufacture sustainable construction materials to meet the nation’s infrastructure needs.” 

EPA scientists have estimated exposure at current limits causes the early deaths of thousands of Americans annually from heart disease and lung cancer as well as causing other health problems. 

Dr. Doris Browne, president of the National Medical Association, the oldest and largest national organization representing African American physicians, hailed the plan as “the bold action needed to protect public health across the country.” 

Appearing with Regan at a news conference, Browne said the proposal is likely to have lasting benefits across the country “but especially for those communities of color and low-income communities that experience the increase in particulate matter pollution.” Smog, soot and other pollution near factories, power plants and other hazards has a “devastating impact on public health,” she said. 

The EPA proposal would require states, counties and tribal governments to meet a stricter air quality standard for fine particulate matter up to 2.5 microns in diameter — far smaller than the diameter of a human hair. A micron, also called a micrometer, is equal to one-millionth of a meter. 

The standard would not force polluters to shut down, but the EPA and state regulators could use it as the basis for other rules that target pollution from specific sources such as diesel-fueled trucks, refineries and power plants. 

A 2022 report by the American Lung Association found that 63 million Americans live in counties that experience unhealthy daily spikes in soot pollution and 21 million live in counties that exceed annual limits for soot pollution. Most of those counties were in 11 Western states, the report said. People of color were 61% more likely than white people to live in a county with unhealthy air quality, the report said. 

Fresno, California, displaced Fairbanks, Alaska, as the metropolitan area with the worst short-term particle pollution, the report found, while Bakersfield, California, continued in the most-polluted slot for year-round particle pollution for the third year in a row. 

As of December 31, five metropolitan areas were not in compliance with current standards, the EPA said. Four of those areas are in California, including the San Joaquin Valley and Los Angeles. Allegheny County, Pennsylvania, which includes Pittsburgh, also is out of compliance. 

The EPA will accept comments on the proposed rule through mid-March and will hold a virtual public hearing over several days. A final rule is expected this summer.

India has announced a $2.3 billion plan to promote “green hydrogen” — hydrogen produced with renewable energy — which experts say could be the clean fuel of the future.

The initiative could help the world’s third-largest emitter of greenhouse gases reach its goal of net zero carbon emissions by 2070. 

A series of incentives are aimed at making green hydrogen affordable by bringing down production costs of a technology that has yet to become commercially viable.  

While India has been rapidly expanding renewables such as solar energy, these will not be enough to meet climate goals in a country whose energy needs are expected to grow more than anywhere in the world over the next two decades. India’s current reliance on carbon-emitting coal, its primary source of electricity, has raised concerns on how it will switch to clean energy.

The government is hoping that investments under what is called the National Hydrogen Mission, will provide the answer.

“For lot of heavy industries like steel, cement and oil refining, green hydrogen can be a better solution to make them cleaner. Their massive energy requirements cannot be met by other renewable sources such as solar and wind,” Vibhuti Garg, South Asia director at the Institute for Energy Economics and Financial Analysis, said.

 “But much will depend on the cost economics” he said. 

Green hydrogen is made by using electricity from renewable sources to split hydrogen from water. The energy it produces creates no carbon emissions. But in an industry still in its infancy, the key lies in significantly lowering production costs. 

“The goal is to bring down its cost over the next five years,” Information and Broadcasting Minister Anurag Thakur said this week while announcing the initiative. He said it will also help India reduce its emissions and become a major exporter in the field.   

Some experts are optimistic. “In the last one year there has been a drop in green hydrogen prices from roughly $4 per kilogram to $3 now,” said Hemant Mallya at the Council for Energy, Environment and Water, a public policy think tank in New Delhi.

He said increased use will bring down costs further. “The eventual target is $1 per kilogram because that is when you start becoming competitive with coal. But even before that if we can hit $2 per kilogram, it will compete with gas currently imported from Russia and that is pretty much achievable with scale and technological advancement.”

The hope is that just as costs for solar power have dropped substantially in recent years and are now lower than that of electricity generated by coal plants, the cost of producing green hydrogen will also reduce over time. 

India’s goal is to produce 5 million tons of green hydrogen per year by 2030. Experts call it an “ambitious” target and point out that at the moment India only has a handful of pilot projects in the sector. 

However, India wants to ensure that it is not left behind in a technology that is now being looked at with much more hope as the world grapples with a climate crisis. In giving a push to green hydrogen, India is following other countries like the United States and those in the European Union that have also approved incentives worth billions of dollars for its development. 

“I think India does not want to miss the bus and is putting the building blocks in place,” said Garg. She pointed out that in the solar energy sector for example, China took the lead in manufacturing the most cost-competitive components for solar panels, leaving most countries, including India, dependent on Chinese imports. “In green hydrogen, India wants to be a pioneer and not wait for other countries to become the lead players.” 

As the government offers financial incentives, some of India’s biggest firms have made commitments to invest in green hydrogen. They include conglomerates like the Adani Group and Reliance Industries and state-owned energy companies.  

Still, experts say there are many challenges ahead in developing the nascent industry. India will have to scale up domestic manufacturing of electrolyzers, which are a key component to develop green hydrogen and also ensure that there is enough renewable energy available to make it. The investments needed will be huge. Domestic industries might have to be incentivized to switch to using green hydrogen.  

India is also eyeing exports of green hydrogen by becoming a cost-competitive source.

“Our aim is to establish India as a global hub of green hydrogen,” Thakur said. “We will make efforts to get at least 10% of the global demand for green hydrogen.” 

Hopes that export markets will emerge if green hydrogen becomes viable have risen after the disruption in global energy markets in the wake of Russia’s invasion of Ukraine. “We need to broaden the horizon and look at exports because the premium on the price of green hydrogen might be a problem domestically, but internationally it is not that much of a challenge for someone in Europe to pay it. And because of the Ukraine crisis for example, countries in Europe, will want to transition quicker than anticipated from natural gas,” according to Mallya.

The world’s glaciers are shrinking and disappearing faster than scientists thought, with two-thirds of them projected to melt out of existence by the end of the century at current climate change trends, according to a new study.

But if the world can limit future warming to just a few more tenths of a degree and fulfill international goals — technically possible but unlikely according to many scientists — then slightly less than half the globe’s glaciers will disappear, said the same study. Mostly small but well-known glaciers are marching to extinction, study authors said.

In an also unlikely worst-case scenario of several degrees of warming, 83% of the world’s glaciers would likely disappear by the year 2100, study authors said.

Thursday’s study in the journal Science examined all of the globe’s 215,000 land-based glaciers — not counting those on ice sheets in Greenland and Antarctica — in a more comprehensive way than past studies. Scientists then used computer simulations to calculate, using different levels of warming, how many glaciers would disappear, how many trillions of tons of ice would melt, and how much it would contribute to sea level rise.

The world is now on track for a 2.7-degree Celsius (4.9 degrees Fahrenheit) temperature rise since pre-industrial times, which by the year 2100 means losing 32% of the world’s glacier mass, or 48.5 trillion metric tons of ice as well as 68% of the glaciers disappearing. That would increase sea level rise by 115 millimeters (4.5 inches) in addition to seas already getting larger from melting ice sheets and warmer water, said study lead author David Rounce.

“No matter what, we’re going to lose a lot of the glaciers,” Rounce, a glaciologist and engineering professor at Carnegie Mellon University, said. “But we have the ability to make a difference by limiting how many glaciers we lose.”

“For many small glaciers it is too late,” said study co-author Regine Hock, a glaciologist at the University of Alaska Fairbanks and the University of Oslo in Norway. “However, globally our results clearly show that every degree of global temperature matters to keep as much ice as possible locked up in the glaciers.”

Projected ice loss by 2100 ranges from 38.7 trillion metric tons to 64.4 trillion tons, depending on how much the globe warms and how much coal, oil and gas is burned, according to the study.

The study calculates that all that melting ice will add anywhere from 90 millimeters (3.5 inches) in the best case to 166 millimeters (6.5 inches) in the worst case to the world’s sea level, 4% to 14% more than previous projections.

That average sea level rise from glaciers would mean more than 10 million people around the world — and more than 100,000 people in the United States — would be living below the high tide line, who otherwise would be above it, said sea level rise researcher Ben Strauss, CEO of Climate Central. Twentieth-century sea level rise from climate change added about 100 millimeters to the surge from 2012 Superstorm Sandy, costing about $8 billion in damage just in itself, he said.

Scientists say future sea level rise will be driven more by melting ice sheets than glaciers.

But the loss of glaciers is about more than rising seas. It means shrinking water supplies for a big chunk of the world’s population, more risk from flood events from melting glaciers and losing historic ice-covered spots from Alaska to the Alps to even near Mount Everest’s base camp, several scientists told The Associated Press.

“For places like the Alps or Iceland … glaciers are part of what makes these landscapes so special,” said National Snow and Ice Data Center Director Mark Serreze, who wasn’t part of the study but praised it. “As they lose their ice in a sense they also lose their soul.”

Hock pointed to Vernagtferner glacier in the Austrian Alps, which is one of the best-studied glaciers in the world, and said “the glacier will be gone.”

The Columbia Glacier in Alaska had 216 billion tons of ice in 2015, but with just a few more tenths of a degree of warming, Rounce calculated it will be half that size. If there’s 4 degrees Celsius (7.2 degrees Fahrenheit) of warming since pre-industrial times, an unlikely worst-case scenario, it will lose two-thirds of its mass, he said.

“It’s definitely a hard one to look at and not drop your jaw at,” Rounce said.

Glaciers are crucial to people’s lives in much of the world, said National Snow and Ice Center Deputy Lead Scientist Twila Moon, who wasn’t part of the study.

“Glaciers provide drinking water, agricultural water, hydropower, and other services that support billions (yes, billions!) of people,” Moon said in an email.

Moon said the study “represents significant advances in projecting how the world’s glaciers may change over the next 80 years due to human-created climate change.”

That’s because the study includes factors in glacier changes that previous studies didn’t and is more detailed, said Ruth Mottram and Martin Stendel, climate scientists at the Danish Meteorological Institute who weren’t part of the research.

This new study better factors in how the glaciers’ ice melts not just from warmer air, but also from water both below and at the edges of glaciers and how debris can slow melt, Stendel and Mottram said. Previous studies concentrated on large glaciers and made regional estimates instead of calculations for each individual glacier.

In most cases, the estimated loss figures Rounce’s team came up with are slightly more dire than earlier estimates.

If the world can somehow limit warming to the global goal of 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming since pre-industrial times — the world is already at 1.1 degrees (2 degrees Fahrenheit) — Earth will likely lose 26% of total glacial mass by the end of the century, which is 38.7 trillion metric tons of ice melting. Previous best estimates had that level of warming melting translating to only 18% of total mass loss.

“I have worked on glaciers in the Alps and Norway which are really rapidly disappearing,” Mottram said in an email. “It’s kind of devastating to see.”

In a move that amplifies the debate over access to abortion in the United States, the Food and Drug Administration this week ruled that a drug used in the majority of abortions in the country can be dispensed by retail pharmacies to individuals with valid prescriptions.

Until the ruling, that drug, mifepristone, could be dispensed only by certified clinics and doctors’ offices, or by specific online pharmacies. Now, retail pharmacies, including those of major chains like CVS and Walgreens, will have the ability, though not the obligation, to carry the medication.

However, it will remain illegal for pharmacies to dispense the medication in at least 12 states, which have passed laws banning abortions.

Mifepristone blocks hormones that contribute to the development of a fetus. When a dose is followed one to two days later with a dose of a second drug, misoprostol, which induces muscle contractions, the result is an abortion. Known as a medical abortion, the two-pill regimen accounts for more than half of all abortions in the U.S. Both mifepristone and misoprostol have other uses unrelated to abortion.

The ruling came days after it was announced that the Justice Department had issued a finding, at the request of the U.S. Postal Service, that it is legal to use the U.S. mail to deliver mifepristone and misoprostol. That finding would apply regardless of the laws of individual states.

State laws differ 

The Supreme Court’s ruling last year that abolished the federal right to an abortion, which was put in place by the 1973 court decision Roe v. Wade, left it to individual states to craft abortion laws themselves. This has led to a patchwork of abortion regulation across the country.

Sixteen states have adopted laws that ban all or practically all abortions. In those states, as well as in several others, laws restricting abortions would also make it illegal to sell mifepristone and misoprostol within their borders, regardless of the FDA’s position.

Other states have explicitly protected the right to abortion in their laws, with several amending their constitutions to do so.

If retail pharmacies opted to sell abortion drugs in states where they are legal, it would further widen the already large gap in abortion access in some parts of the country. In certain regions, particularly states in the Deep South, a woman seeking access to an abortion has to travel hundreds of miles to reach a state that has not banned the procedure.

Abortion rights activists cheered 

Supporters of the right to an abortion said that they were encouraged by the FDA’s ruling.

“Today’s news is a step in the right direction for health equity. Being able to access your prescribed medication abortion through the mail or to pick it up in person from a pharmacy like any other prescription is a game-changer for people trying to access basic health care,” Alexis McGill Johnson, president and CEO of Planned Parenthood Federation of America, said in a statement.

However, advocates also noted that the sale of the pills would remain illegal in 12 states, because of abortion bans passed by state legislatures.

“Today’s announcement means that people in states where abortion is legal will be able to consult with their health care providers and obtain medication abortion in the way that works best for them — whether it’s through their neighborhood pharmacy or through the mail,” Nancy Northup, president and CEO of the Center for Reproductive Rights, said in a statement. “However, 12 states have banned abortion, and this move will not change anything for the people in those states, which is why Congress must pass the Women’s Health Protection Act to ensure the right to access abortion care is protected nationwide.”

Abortion-rights opponents unhappy

Groups that support the restriction or outright elimination of abortion in the U.S. were unhappy with the ruling, with some criticizing the administration of President Joe Biden over its support for abortion rights.

Although the medical establishment, including the FDA, has said that medical abortions are safe, anti-abortion-rights groups point to rare side effects, including heavy bleeding and infection, as proof that they are dangerous.

“Today’s announcement is yet another in a long train of actions the Biden administration has taken that put women at grave risk, in its headlong rush to push abortion drugs on the American public,” Steven H. Aden, chief legal officer and general counsel for Americans United for Life, said in a statement emailed to VOA.

“The Biden administration has once again proved that it values abortion industry profits over women’s safety and unborn children’s lives,” Marjorie Dannenfelser, president of Susan B. Anthony Pro-Life America, said in a statement.

Retail pharmacies consider options 

It was not clear whether retail pharmacies, including those of large chains, would carry mifepristone and misoprostol in states that have not made abortion illegal. To do so, they would have to comply with special rules put forward by the FDA.

They would also have to assess the reputational costs and benefits of a decision that will likely have repercussions that extend beyond the balance sheet.

“We’re reviewing the FDA’s updated Risk Evaluation and Mitigation Strategy (REMS) drug safety program for mifepristone to determine the requirements to dispense in states that do not restrict the dispensing of medications prescribed for elective termination of pregnancy,” Amy Thibault, lead director of external communications for CVS Pharmacy, told VOA.

Fraser Engerman, a senior director for external relations with Walgreen Co., told VOA, “We look forward to reviewing the FDA’s announcement and mifepristone REMS program, and we will continue to enable our pharmacists to dispense medications consistent with federal and state law.”

The Food and Drug Administration on Tuesday finalized a rule change that allows women seeking abortion pills to get them through the mail, replacing a long-standing requirement that they pick up the medicine in person. 

The Biden administration implemented the change last year, announcing it would no longer enforce the dispensing rule. Tuesday’s action formally updates the drug’s labeling to allow women to get a prescription via telehealth consultation with a health professional, and then receive the pills through the mail, where permitted by law. 

Still, the rule change’s impact has been blunted by numerous state laws limiting abortion broadly and the pills specifically. Legal experts foresee years of court battles over access to the pills, as abortion-rights proponents bring test cases to challenge state restrictions. 

For more than 20 years, the FDA labeling had limited dispensing to doctor’s offices and clinics, due to safety concerns. During the COVID-19 pandemic, the FDA temporarily suspended the in-person requirement. The agency later said a new scientific review by agency staff supported easing access, concurring with numerous medical societies that had long said the restriction wasn’t necessary. 

Two drugmakers that make brand-name and generic versions of abortion pills requested the latest FDA label update. Agency rules require a company to file an application before modifying dispensing restrictions on drugs. 

Danco Laboratories, which sells branded Mifeprex (mifepristone), said in a statement the change “is critically important to expanding access to medication abortion services and will provide healthcare providers” another option for prescribing the drug. 

More than half of U.S. abortions are now done with pills rather than surgery, according to the Guttmacher Institute, a research group that supports abortion rights. 

The FDA in 2000 approved mifepristone to terminate pregnancies of up to 10 weeks when used with a second drug, misoprostol. Mifepristone is taken first to dilate the cervix and block the progesterone hormone, which is needed to sustain a pregnancy. Misoprostol is taken 24 to 48 hours later, causing the uterus to contract and expel pregnancy tissue. 

Bleeding is a common side effect, though serious complications are very rare. The FDA says more than 3.7 million U.S. women have used mifepristone since its approval. 

Several FDA-mandated safety requirements remain in effect, including training requirements to certify that prescribers can provide emergency care in the case of excessive bleeding. Pharmacies that dispense the pills also need a certification.

Walter Cunningham, the last surviving astronaut from the first successful crewed space mission in NASA’s Apollo program, died Tuesday in Houston. He was 90.

NASA confirmed Cunningham’s death in a statement but did not include its cause. Spokespersons for the agency and Cunningham’s wife, Dot Cunningham, did not immediately respond to questions.

Cunningham was one of three astronauts aboard the 1968 Apollo 7 mission, an 11-day spaceflight that beamed live television broadcasts as they orbited Earth, paving the way for the moon landing less than a year later.

Cunningham, then a civilian, crewed the mission with Navy Capt. Walter M. Schirra and Donn F. Eisele, an Air Force major. Cunningham was the lunar module pilot on the space flight, which launched from Cape Kennedy Air Force Station, Florida, on October 11 and splashed down in the Atlantic Ocean south of Bermuda.

NASA said Cunningham, Eisele and Schirra flew a near perfect mission. Their spacecraft performed so well that the agency sent the next crew, Apollo 8, to orbit the moon as a prelude to the Apollo 11 moon landing in July 1969.

The Apollo 7 astronauts also won a special Emmy award for their daily television reports from orbit, during which they clowned around, held up humorous signs and educated earthlings about space flight.

It was NASA’s first crewed space mission since the deaths of the three Apollo 1 astronauts in a launch pad fire January 27, 1967.

Cunningham recalled Apollo 7 during a 2017 event at the Kennedy Space Center, saying it “enabled us to overcome all the obstacles we had after the Apollo 1 fire and it became the longest, most successful test flight of any flying machine ever.”

Cunningham was born in Creston, Iowa, and attended high school in California before enlisting with the Navy in 1951 and serving as a Marine Corps pilot in Korea, according to NASA. He later obtained bachelor’s and master’s degrees in physics from the University of California at Los Angeles, where he also did doctoral studies, and worked as scientist for the Rand Corporation before joining NASA.

In an interview the year before his death, Cunningham recalled growing up poor and dreaming of flying airplanes, not spacecraft.

“We never even knew that there were astronauts when I was growing up,” Cunningham told The Spokesman-Review.

After retiring from NASA in 1971, Cunningham worked in engineering, business and investing, and became a public speaker and radio host. He wrote a memoir about his career and time as an astronaut, “The All-American Boys.” He also expressed skepticism in his later years about human activity contributing to climate change, bucking the scientific consensus in writing and public talks, while acknowledging that he was not a climate scientist.

Although Cunningham never crewed another space mission after Apollo 7, he remained a proponent of space exploration. He told the Spokane, Washington, paper last year, “I think that humans need to continue expanding and pushing out the levels at which they’re surviving in space.”

Cunningham is survived by his wife, his sister Cathy Cunningham, and his children Brian and Kimberly.

A top health official in China has said that the fatalities from the latest surge in COVID-19 cases are “increasing” but within the normal range for mortality.

In an interview with state broadcaster China Central Television (CCTV), Jiao Yahui, a National Health Commission official, said, “We have a huge base, so what people feel is that the severe cases, the critical cases or the fatalities are increasing.

“Relative to the rest of the world, the infection peaks we are faced with across the country are not unusual,” she added. 

The contrast between statements by Chinese officials assessing the COVID situation and social media footage of crowded hospital hallways and long lines at clinics prompted leading scientists advising the World Health Organization to call Tuesday for a “more realistic picture” about what China is experiencing after the pivot from “zero-COVID.”

Normal mortality is the number of deaths authorities expect for a specific period based on long-term population data. Excess mortality reveals the difference between the number of deaths caused during the current wave of COVID and the number of fatalities expected had the pandemic not occurred. The excess mortality number has been used worldwide during the pandemic to provide a better sense of how many people have died of COVID.

Tong Zhaohui, vice president of Chaoyang Hospital in Beijing, agreed that while the actual number of deaths is growing, the fatalities remain a small percentage of China’s population.

“Think how many people around you have been infected but how many have developed critical cases or pneumonia? I think everyone has the idea,” he told CCTV.

China began relaxing its stringent zero-COVID policy in early December. Since then, Tong has supervised treatment for critically ill COVID patients at two major hospitals in Beijing.

Tong said, “I roughly counted, both severe and critical cases (of COVID) at the two designated hospitals accounted for 3% to 4% of infected patients.” He added that the actual number can’t be determined because PCR testing is no longer mandatory.

Beijing reported three new COVID deaths for Monday, taking the official death toll to 5,253 since the pandemic began in January 2020. China’s population was over 1.4 billion people in 2021.

CCTV’s coverage acknowledged that the number of fever outpatients in some hospitals increased tenfold, and one doctor saw up to 150 patients in one night. A fever patient cannot be assumed to be a COVID patient.

Photos and videos of hospitals full of sick people waiting to be treated are circulating on social media from facilities across the country. Reuters visited a Shanghai hospital and reported finding crowded hallways and emergency rooms. China’s censors are moving quickly to keep photos and videos from circulating inside the country, but many are leaping the country’s Great Firewall for the internet and posting photos and videos that were said to be from hospitals in China’s central and southern Hunan province as well as other cities.

Although VOA Mandarin was unable to independently verify the videos circulating on Twitter that are said to show hospitals in Hunan, a staffer who answered the phone at Changsha No. 1 People’s Hospital in Changsha, the province’s capital, said the hospital has no vacant beds left and new patients are being asked to go to other hospitals. According to Baike, China’s version of Wikipedia, the hospital has a total capacity of 1,593 beds. The staffer said that while many doctors have tested positive, they are still working.

Social media videos from various cities show long lines waiting to be admitted outside crematoriums.

In an interview with Da Jiangdong Studio, an affiliate of the state-run newspaper People’s Daily, Chen Erzhen, vice president of Shanghai’s Ruijin Hospital and a member of the city’s COVID expert advisory panel, estimated that 70% of population of 25 million people in Shanghai may have been infected. The interview was conducted December 31 and published Tuesday.

“Now the spread of the epidemic in Shanghai is very wide, and it may have reached 70% of the population, which is 20 to 30 times more than (in April and May),” he told Da Jiangdong Studio. Shanghai endured a two-month long lockdown in April and May, during which over 600,000 residents were infected and already weakened global supply chains were further strained.

China could see as many as 25,000 deaths a day from COVID later in January, according to a Bloomberg report.

That daily total is “roughly equivalent to China’s normal daily death toll from all other causes,” according to The British Medical Journal referencing research published December 20 from Airfinity, a London-based research firm that focuses on predictive health analytics.

Mortalities from the contagious respiratory illness will probably peak around January 23, the second day of the annual new year holiday, according Airfinity.

China said it had submitted genome sequence data from recently sampled COVID-19 cases to GISAID, an international database hosted by Germany, ahead of a meeting with WHO officials on Tuesday.

Before the meeting, Reuters reported that two unnamed scientists affiliated with WHO had asked Beijing for a “more realistic picture” of COVID in China.

Some experts doubted that Beijing would be forthright in its statistical offerings.

Alfred Wu, associate professor at the Lee Kuan Yew School of Public Policy at National University of Singapore, told Reuters, “I don’t think China will be very sincere in disclosing information.”

“They would rather just keep it to themselves, or they would say nothing happened, nothing is new,” said Wu. “My own sense is that we could assume that there is nothing new … but the problem is China’s transparency issue is always there.”

Advocates for education and health care in Malawi are criticizing the government’s decision to close schools in two cities to try to contain a cholera outbreak. 

The Presidential Taskforce on Coronavirus and Cholera said in a statement Monday that the suspension is applied to all primary and secondary schools in the capital, Lilongwe, and commercial hub, Blantyre.

Khumbize Kandodo Chiponda, co-chairperson of the taskforce and Malawi’s minister of health, told a press conference Tuesday the decision is a result of the continuing increase in the number of cholera cases in the two cities.

As of Monday, the bacterial disease, spread by dirty water, had killed more than 620 people out of 18,222 cases since the outbreak began in March. 

Chiponda expressed fear for the safety of students and others if the schools remain open, adding that in just seven days, Blantyre recorded 792 cases with 36 deaths, and Lilongwe recorded 536 cases with 36 deaths.

But Malawian education and health rights campaigners say the timing of the suspension was wrong.

Hastings Moloko, trustee of the Private Schools Association of Malawi, told a press conference Monday that there is no logic in suspending learning in only two out of the 28 affected districts. 

“The playing field is not leveled,” he said. “It is schools in Blantyre and Lilongwe that have been affected. While other students are not learning, students everywhere else in the country are learning. And yet these students will sit for exactly the same exams, exactly at the same time. So, Blantyre and Lilongwe students will be disadvantaged in terms of time to cover their syllabuses.”

Moloko said there is also no scientific evidence that cholera spreads more in schools than in homes.

Cholera is an acute diarrheal infection caused by ingesting food or water contaminated with bacteria. The disease affects both children and adults, and if untreated, can kill within hours.

Agnes Nyalonje, minister of education in Malawi, said the move is to protect the lives of the learners in these two cholera hotspot districts. 

“The issue is a balance between protection of life and continuity of learning,” she said. “We have information that shows that currently across all schools, we are short of 1,262 boreholes or water supply in schools that need water supply. And we are saying personal hygiene and school hygiene have to go hand in hand.”

Nyalonje said her ministry has put measures in place that allow students in the closed schools to take lessons through distance learning, as was the case when the schools shut down for the COVID-19 pandemic.

A new report by the Africa Center for Strategic Studies says “once in a hundred years” floods will become more common in coastal communities due to rising sea levels caused by climate change. As a stretch of West Africa’s coast is set to become the world’s largest megalopolis and an economic powerhouse, academics worry rising sea levels will stymie growth and impact the continent and the world. Henry Wilkins reports from Ganvie, Benin.

A new year is around the corner. And many use this time to make New Year’s resolutions. Why do people do that, you might ask?

“It’s a new calendar year,” said Mandy Doria, a certified counselor at the University of Colorado, speaking with The Associated Press. ‘We have a chance to leave behind all of the old stuff, good and bad, from the previous year and move forward and start to make new plans, new goals, and we may feel excited and recharged by that.”

That feeling of hope can dissipate amid day-to-day stressors but there are ways to set goals without feeling like you’re setting yourself up for failure, said Doria.

“There is a concept called smart goals,” she said. “So smart goals should be specific. They should be measurable. They should be attainable. And they should be reliable as well as time-based. So, for example, I might want to move my body more, and so I might start by going to the gym or going to yoga once a week. And then after three weeks, maybe I build on that so I can make time specific goals as well. And then it’s measurable and it’s specific.”

Knowing why helps

Christine Whelan, a clinical professor at the University of Wisconsin-Madison, and the author of an Audible Original 10-lecture series called “Finding Your Purpose,” said if people know why they’ve set goals, they’re more likely to reach them.

“Why is it that you want to make a change?” she asked. “These are questions of purpose and values and meaning. So maybe you do want to go to the gym and lose a couple of pounds. But why? And if you can get to that core reason for why, research finds that you are much more likely to actually follow through on your goals and make it happen.”

Whelan said there are other ways to start the new year by making it more of a reflective exercise rather than an intimidating to-do list.

“Rather than New Year’s resolutions, one thing that I’ve loved to do over the years is write a letter to myself at New Year’s — the next year (2023),” said Whelan. “And in that letter, what I do is I think about where I want to be, where I am right now, the things that are important to me, my values and purpose statement, my hopes and goals for the year ahead.”

A goal is a process

In an interview with the AP, Edward Hirt, a professor in the Department of Psychological and Brain Sciences at Indiana University, said to be successful at sticking with a New Year’s resolution, one must understand that pursuing a goal is a process.

“Because I think most of the time in many goal pursuit situations, we are really hard on ourselves if we don’t get what we anticipate we should be,” said Hirt. “If we can kind of break down the goal pursuit process into sub-stages, sub kind of goals along the way and can sort of see ourselves meeting those things and take pride in accomplishing those pieces of the larger process, it’s much more reinforcing to us.”

Hirt said people should also reflect on their progress to see how far they’ve come rather than only focusing on the endpoint.

Howard Fischer, a 63-year-old investor living north of New York City, has a wish for when he dies. He wants his remains to be placed in a vessel, broken down by tiny microbes and composted into rich, fertile soil.

Maybe his composted remains could be planted outside the family home in Vermont, or maybe they could be returned to the earth elsewhere. “Whatever my family chooses to do with the compost after it’s done is up to them,” Fischer said.

“I am committed to having my body composted and my family knows that,” he added. “But I would love for it to happen in New York where I live rather than shipping myself across the country.”

Democratic Gov. Kathy Hochul signed legislation Saturday to legalize natural organic reduction, popularly known as human composting, making New York the sixth state in the nation to allow that method of burial.

Washington state became the first state to legalize human composting in 2019, followed by Colorado and Oregon in 2021, and Vermont and California in 2022.

For Fischer, this alternative, green method of burial aligns with his philosophical view on life: to live in an environmentally conscious way.

The process goes like this: the body of the deceased is placed into a reusable vessel along with plant material such as wood chips, alfalfa and straw. The organic mix creates the perfect habitat for naturally occurring microbes to do their work, quickly and efficiently breaking down the body in about a month’s time.

The end result is a heaping cubic yard of nutrient-dense soil amendment, the equivalent of about 36 bags of soil, that can be used to plant trees or enrich conservation land, forests, or gardens.

For urban areas such as New York City where land is limited, it can be seen as a pretty attractive burial alternative.

Michelle Menter, manager at Greensprings Natural Cemetery Preserve, a cemetery in central New York, said the facility would “strongly consider” the alternative method.

“It definitely is more in line with what we do,” she added.

The 52-hectare nature preserve cemetery, nestled between protected forest land, offers natural, green burials which is when a body can be placed in a biodegradable container and into a gravesite so that it can decompose fully.

“Every single thing we can do to turn people away from concrete liners and fancy caskets and embalming, we ought to do and be supportive of,” she said.

But not all are onboard with the idea.

The New York State Catholic Conference, a group that represents bishops in the state, has long opposed the bill, calling the burial method “inappropriate.”

“A process that is perfectly appropriate for returning vegetable trimmings to the earth is not necessarily appropriate for human bodies,” Dennis Poust, executive director of the organization, said in a statement.

“Human bodies are not household waste, and we do not believe that the process meets the standard of reverent treatment of our earthly remains,” he said.

Katrina Spade, the founder of Recompose, a full-service green funeral home in Seattle that offers human composting, said it offers an alternative for people wanting to align the disposition of their remains with how they lived their lives.

She said “it feels like a movement” among the environmentally aware.

“Cremation uses fossil fuels and burial uses a lot of land and has a carbon footprint,” said Spade. “For a lot of folks being turned into soil that can be turned to grow into a garden or tree is pretty impactful.”

New Year’s Eve in China prompted an outpouring of reflection online, some of it critical, about the strict zero-COVID policy the country adhered to for almost three years and the impact of its abrupt reversal this month.

The sudden change to live with the virus has prompted a wave of infections across the country, a further drop in economic activity and international concern, with Britain and France the latest countries to impose curbs on travelers from China.

Three years into the pandemic, China this month acted to align with a world that has largely reopened to live with COVID, after unprecedented protests that became a de facto referendum against the zero-COVID policy championed by President Xi Jinping. 

The protests were the strongest show of public defiance in Xi’s decade-old presidency and coincided with grim growth figures for China’s $17 trillion economy.

On Saturday, people in the central Chinese city of Wuhan, the epicenter of the pandemic, expressed hope the new year would bring better fortune.

Several people in Wuhan bemoaned how widely the virus has spread after lifting of all the pandemic curbs, with one, 45-year-old Chen Mei, saying she just hopes that in 2023 her teenage daughter can resume normal classes over the long term.

“When she can’t go to the school and can only have classes online it’s definitely not an effective way of learning,” she said.

“Kids don’t have such good self discipline. And then for us adults sometimes because of the epidemic controls we have been locked up at home. It’s definitely had an impact.”

Thousands of users on China’s Twitter-like Weibo criticized the removal of a viral video made by local outlet Netease News that collated real-life stories from 2022 that had captivated the Chinese public.

Many of the stories included in the video, which by Saturday could not be seen or shared on domestic social media platforms, highlighted the difficulties ordinary Chinese faced as a result of the strict COVID policy.

Weibo and Netease did not immediately reply to a request for comment.

One Weibo hashtag about the video garnered almost 4 million hits before it disappeared from platforms around noon on Saturday. Social media users created new hashtags to keep the comments pouring in.

“What a perverse world, you can only sing the praises of the fake but you cannot show real life,” one user wrote, attaching a screenshot of a blank page that is displayed when searching for the hashtags.

The disappearance of the videos and hashtags, seen by many as an act of censorship, suggests the Chinese government still sees the narrative surrounding its handling of the disease as a politically sensitive issue.

Overwhelmed hospital, funeral homes

The wave of new infections has overwhelmed hospitals and funeral homes across the country, with lines of hearses outside crematoria fueling public concern.

China, a country of 1.4 billion people, reported one new COVID death for Friday, the same as the day before — numbers which do not match the experience of other countries after they reopened.

U.K.-based health data firm Airfinity said on Thursday around 9,000 people in China are probably dying each day from COVID. Cumulative deaths in China since Dec. 1 have likely reached 100,000, with infections totaling 18.6 million, it said.

At the central hospital of Wuhan, where former COVID whistleblower Li Wenliang worked and later died of the virus in early 2020, patient numbers were down Saturday compared with the rush of the past few weeks, a hazmat-suit wearing worker outside the hospital’s fever clinic told Reuters.

“This wave is almost over,” the worker said.

A pharmacist whose store is next to the hospital said most people in the city had now been infected and recovered.

“It is mainly old people who are getting sick with it now,” he said. “They have underlying conditions and can get breathing issues, lung infections or heart problems.”

New year, new challenges

In the first indication of the toll on China’s giant manufacturing sector from the change in COVID policy, data Saturday showed factory activity shrank for the third straight month in December and at the sharpest pace in nearly three years.

Besides the growing economic toll, rising infections after lifting of the restrictions also have prompted international concern, particularly regarding the possibility of a new, stronger variant emerging out of China.

Britain and France became the latest countries to require travelers from China to provide negative COVID-19 tests. The United States, South Korea, India, Italy, Japan and Taiwan have all imposed similar measures.

The World Health Organization on Friday once again urged China’s health officials to regularly share specific and real-time information on the COVID situation in the country, as it continues to assess the latest surge in infections.

China’s narrow criteria for identifying deaths caused by COVID-19 will underestimate the true toll of the pandemic and could make it harder to communicate the best ways for people to protect themselves, health experts have warned.

The World Health Organization met Chinese officials for talks on Friday about the surge in COVID-19 cases, urging them to share real-time data so other countries could respond effectively.

The rise in infections in China has triggered concern around the globe and questions about its data reporting, with low official figures for cases and deaths despite some hospitals and morgues being overwhelmed.

The talks came after WHO chief Tedros Adhanom Ghebreyesus urged Beijing to be more forthcoming on the pandemic situation in the world’s most populous country.

The U.N. health agency said the meeting was “to seek further information on the situation, and to offer WHO’s expertise and further support.”

It said officials from China’s National Health Commission and National Disease Control and Prevention Administration briefed the WHO on China’s evolving strategy and actions on epidemiology, variant monitoring, vaccination, clinical care, communication and research and development.

“WHO again asked for regular sharing of specific and real-time data on the epidemiological situation — including more genetic sequencing data, data on disease impact including hospitalizations, intensive care unit admissions and deaths,” it said.

It asked for data on vaccinations delivered and vaccination status, especially in vulnerable people and those over age 60.

‘Timely publication of data’

“WHO reiterated the importance of vaccination and boosters to protect against severe disease and death for people at higher risk,” the Geneva-based organization said.

“WHO called on China to strengthen viral sequencing, clinical management and impact assessment, and expressed willingness to provide support on these areas, as well as on risk communications on vaccination to counter hesitancy.”

The U.N. agency said Chinese scientists were invited to engage more closely in WHO-led COVID-19 expert networks and asked them to present detailed data at a virus evolution advisory group meeting Tuesday.

“WHO stressed the importance of monitoring and the timely publication of data to help China and the global community to formulate accurate risk assessments and to inform effective responses,” it said.

China said this month it would end mandatory quarantine for people arriving in the country and that it had abandoned strict measures to contain the virus.

The surge in cases in China comes almost exactly three years after the first infections were recorded in the Chinese city of Wuhan in late 2019.

Since then, more than 650 million confirmed COVID cases and over 6.6 million deaths have been reported, though the U.N. health agency acknowledges this will be a vast undercount.

The search for the origin of the virus remains unresolved, with Tedros insisting all hypotheses remain on the table, including the theory that the virus escaped from Wuhan’s virology laboratories.

Tedros has called on China to share data and conduct the studies requested by the WHO to better understand where the SARS-CoV-2 virus that causes COVID-19 disease sprang from.

In 2022, photographers with The Associated Press captured signs of a planet in distress as climate change reshaped many lives.

That distress was seen in the scarred landscapes in places where the rains failed to come. It was felt in walloping storms, land-engulfing floods, suffocating heat and wildfires no longer confined to a single season. It could be tasted in altered crops or felt as hunger pangs when crops stopped growing. And taken together, millions of people were compelled to pick up and move as many habitats became uninhabitable.

2022 will be a year remembered for destruction brought on by a warming planet and, according to scientists, was a harbinger for even more extreme weather.

Parched earth

In June, two young men sat smoking in front of a boat that had previously been under water. The waterline in parts of Lake Mead National Recreation Area in Nevada had dropped so much that the boat was now standing up in the mud. Such dramatic manifestations were seen in myriad places. 

In Germany, drought combined with a bark beetle infestation left large swaths of Harz forest trees spindly, while in Kenya mothers struggled to keep their children nourished and animals died because of a lack of water. Along the Solimoes River in the Brazilian Amazon, houseboat dwellers found themselves living on mud instead of water, as parts dried up.

In eastern France, normally lush sunflowers looked as if they had been fried, their leaves withered, and seeds blackened. Similar scars on the Earth’s surface were seen in reef-like structures exposed by receding waters in Utah’s Great Salt Lake, the cracked bed of Hungary’s Lake Velence and the shrunken Yangtze River in southwestern China.

Storms and floods

While a lack of rain did damage in many places, in others too much precipitation altered landscapes and swallowed lives. Sometimes the same region, in a short amount of time, went from drought to deluge — what scientists refer to as a “whiplash effect.” This happened in parts of Yellowstone National Park last summer.

The country hardest hit by floods was Pakistan, with a third of its land submerged, millions of people displaced and at least 1,700 killed. But many countries were hit hard by storms.

In Cuba, a tropical cyclone in June led to so much flooding that rescuers moved through the streets of Havana in boats. Just a few months later, Hurricane Ian slammed into the island before continuing to Florida, leaving destruction and death in its wake.

Heavy floods were also seen in parts of Nigeria, India, Indonesia and numerous other places, while in one part of Brazil, a common aftereffect of flooding — landslides — killed more than 200 people.

To be sure, there were human attempts to better prepare and deal with flooding. One example: Chinese authorities continued to develop and expand “sponge cities,” which aim to use porous pavement and green spaces to absorb water and reduce the destruction of flooding.

Heat and fire

In recent years, wildfires have become commonplace across the Western U.S. amid a 23-year drought and rising temperatures. Compared to last year, there were slightly fewer wildfires in 2022 in California — the state routinely hardest hit — but many blazes still chewed through land and homes.

America was hardly alone. There were significant fires in Portugal, Greece, Argentina and many other countries. Images like a living room engulfed in flames, an evacuated woman clinging to a police officer and a man using a branch to protect his home were visceral reminders of the fury that fires unleash.

Along with fires, there were periodic bouts of extreme heat. A sweating British soldier, wearing a traditional bearskin hat outside Buckingham Palace, captured a reality for many Brits, as temperatures reached 104 degrees Fahrenheit (40.3 degrees Celsius), a record for the country.

How people coped with sauna-like conditions depended on the place. In Madrid, a fountain at an urban beach provided relief to parents and children. In Hungary, three people cooled off in a fill-up pool. And in Los Angeles, a woman stuck her head in front of an open fire hydrant.

Imperiled food

In October, Wilbur Kuzuzuk pulled a spotted seal to the edge of the lagoon in Shishmaref, a town in western Alaska that is on the verge of disappearing because of climate change.

The 600 residents of the Inupiat village have stayed put despite increasing risks to their way of life, including their food supply, as warming seas encroach on land and warming temperatures hurt habitats. But residents like Kuzuzuk know Shishmaref’s days are likely numbered: Twice the town has voted to relocate, though nothing has been put in motion.

All around the world there were clear threats to the food supply. In India, floods damaged corn and other crops, leaving farmers no choice but to try to salvage as much as possible. In Kenya and surrounding countries, drought increased hunger and pushed villagers to dig ever deeper in search of groundwater.

Climate migration

Taken together, all these problems pushed millions of people to migrate. Perhaps nowhere was that clearer than in Somalia, where severe drought led to starvation and prompted thousands of people to flee. Many migrants ended up in makeshift camps, like the one in Dollow, emaciated, young children in tow, desperately seeking food and water.

Much of the migration happened within borders. In India’s Ladakh region, a cold mountainous desert that borders China and Pakistan, shrinking grazable land, along with other effects of climate change, continued to force many to migrate from sparsely populated villages to urban settlements.

In Indonesia, a big driver of migration was encroaching seas. In Central Java, homes not outfitted with raised floors were swallowed, pushing those who didn’t have the means to seek other abodes.

In Kenya, a woman named Winnie Keben recounted how she lost her leg to a crocodile attack. She blamed the attack, in part, on the fact that rising water levels around Lake Baringo have brought animals closer to humans. Many scientists attribute that to climate change.

Keben’s home was also washed away, sending her family to another village.

As COVID-19 infections surge in China, the U.S. Centers for Disease Control and Prevention is considering sampling wastewater taken from international aircraft to track any emerging new variants, the agency told Reuters.

Such a policy would offer a better solution to tracking the virus and slowing its entry into the United States than new travel restrictions announced this week by the U.S. and other countries, which require mandatory negative COVID tests for travelers from China, three infectious disease experts told Reuters.

Travel restrictions, such as mandatory testing, have so far failed to significantly curb the spread of COVID, said Dr. Michael Osterholm, an infectious disease expert at the University of Minnesota.

“They seem to be essential from a political standpoint. I think each government feels like they will be accused of not doing enough to protect their citizens if they don’t do these,” he said.

The United States this week also expanded its voluntary genomic sequencing program at airports, adding Seattle and Los Angeles to the program. That brings the total number of airports gathering information from positive tests to seven.

But experts said that may not provide a meaningful sample size.

A better solution would be testing wastewater from airlines, which would offer a clearer picture of how the virus is mutating, given China’s lack of data transparency, said Dr. Eric Topol, a genomics expert and director of the Scripps Research Translational Institute in La Jolla, California.

Getting wastewater off planes from China “would be a very good tactic,” Topol said, adding that it’s important that the United States upgrade its surveillance tactics “because of China being so unwilling to share its genomic data.”

China has said criticism of its COVID statistics is groundless and downplayed the risk of new variants, saying it expects mutations to be more infectious but less severe. Still, doubts over official Chinese data have prompted many places, including the United States, Italy and Japan, to impose new testing rules on Chinese visitors as Beijing lifted travel controls.

Airplane wastewater analysis is among several options the CDC is considering to help slow the introduction of new variants into the United States from other countries, CDC spokesperson Kristen Nordlund said in an email.

The agency is grappling with a lack of transparency about COVID in China after the country of 1.4 billion people abruptly lifted strict COVID lockdowns and testing policies, unleashing the virus into an under-vaccinated and previously unexposed population.

“Previous COVID-19 wastewater surveillance has shown to be a valuable tool and airplane wastewater surveillance could potentially be an option,” she wrote.

French researchers reported in July that airplane wastewater tests showed requiring negative COVID tests before international flights does not protect countries from the spread of new variants. They found the omicron variant in wastewater from two commercial airplanes that flew from Ethiopia to France in December 2021 even though passengers had been required to take COVID tests before boarding.

California researchers reported in July that sampling of community wastewater in San Diego detected the presence of the alpha, delta, epsilon and omicron variants up to 14 days before they started showing up on nasal swabs.

Osterholm and others said mandatory testing before travel to the United States is unlikely to keep new variants out of the country.

“Border closures or border testing really makes very little difference. Maybe it slows it down by a few days,” he said, because the virus is likely to spread worldwide, and could infect people in Europe or elsewhere who may then bring it to the United States.
…

The world is getting warmer, winters included. The United States, however, has experienced severe winter storms in recent years, and experts are taking a closer look at the link between these extreme cold events and climate change.

While the link between global warming and heat waves is very direct, the behavior of winter storms is governed by complex atmospheric dynamics that are more difficult to study.

Even so, “there are certain aspects of winter storms … where the climate change linkages are fairly strong and robust,” Michael Mann, a climatologist at the University of Pennsylvania, told AFP.

For example, the warming of bodies of water — lakes or oceans — influences the amount of snowfall.

In the United States, a mechanism called “lake-effect snow” occurs around the Great Lakes region on the Canadian border. The city of Buffalo, which sits on the shores of one of the Great Lakes, was hit hard by a lethal snowstorm over Christmas weekend.

The collision between cold air from the north with the warmer water of these lakes causes convection, which leads to snowfall.

“The warmer those lake temperatures, the more moisture (is) in the air, and the greater potential for lake-effect snows,” Michael Mann wrote in a 2018 paper.

“Not surprisingly, we see a long-term increase in lake effect snowfalls as temperatures have warmed during the last century.”

Polar vortex

There is, however, no consensus on other mechanisms, such as the effect of climate change on the polar vortex and jet stream air currents.

The polar vortex is an air mass above the North Pole, located high in the stratosphere. Humans dwell in the troposphere, and the stratosphere is located just above it.

It is surrounded by a band of rotating air, which acts as a barrier between the cold air in the north and the warmer air in the south. As the polar vortex weakens, this band of air begins to undulate and take on a more oval shape, bringing more cold air southward.

According to a 2021 study, this type of disturbance is occurring more often and is reflected during the following two weeks, lower in the atmosphere, where the jet stream is located.

This air current, which blows from west to east, again following the border between cold and warm air, then meanders in such a way that it allows cold air from the north to intrude at lower latitudes, particularly over the eastern United States.

“Everybody agrees that when the polar vortex becomes perturbed or disrupted, there is an increase in the probability of severe winter weather,” Judah Cohen, lead author of the study and climatologist for Atmospheric and Environmental Research (AER), told AFP.

And this “stretched” polar vortex is exactly what was observed just before the storm that hit the United States this December, he pointed out.

The same phenomenon was seen in February 2021, when a bitter cold snap hit Texas, causing massive power outages.

‘Active debate’

But the heart of the debate lies elsewhere: What is causing these increased disturbances in the polar vortex?

According to Cohen, they are linked to changes in the Arctic, accelerated by climate change. On the one hand, the rapid melting of sea ice, and on the other, an increase in snow cover in Siberia.

“This is a topic that I have been studying for over 15 years, and I am more confident today in the link than I have ever been in the past,” he told AFP.

This last point, however, remains “an active debate within the scientific community,” Mann said.

“Climate models are not yet capturing all of the underlying physics that may be relevant to how climate change is impacting the behavior of the jet stream.”

Future studies will still be needed in the coming years to unravel the mystery of these complex chain reactions.

The U.S. Justice Department is suing one of the largest U.S. drug distributors for failing to report suspicious orders of prescription opioids, saying the company’s “years of repeated violations” contributed to the deadly U.S. opioid epidemic. 

In a civil lawsuit filed Thursday, the department alleges that AmerisourceBergen and two subsidiaries violated the Controlled Substances Act by failing to report “at least hundreds of thousands” of suspicious orders for prescription painkillers to the Drug Enforcement Administration.

The department is seeking potentially billions of dollars in penalties.

“For years, AmerisourceBergen prioritized profits over its legal obligations and over Americans’ well-being,” Associate Attorney General Vanita Gupta said during a press call.

Under the Controlled Substances Act, distributors of controlled drugs are required to monitor and report suspicious orders to the drug agency.

The lawsuit alleges that AmerisourceBergen failed to report “numerous orders from pharmacies that AmerisourceBergen knew were likely facilitating diversion of prescription opioids.”

The complaint cites five such pharmacies.

A Florida pharmacy and a West Virginia pharmacy received opioids from AmerisourceBergen that the company allegedly knew “were likely being sold in parking lots for cash,” according to the complaint.

In Colorado, AmerisourceBergen distributed prescription painkillers to a pharmacy it allegedly knew was its largest purchaser of oxycodone 30mg tablets in the state.

AmerisourceBergen identified 11 patients at the pharmacy as potential “drug addicts.” Two of those patients later died of overdoses, according to the lawsuit.

In New Jersey, an online pharmacy that received opioids from AmerisourceBergen has pleaded guilty to illegally selling controlled substances, while the chief pharmacist at another pharmacy has been indicted for drug diversion.

“These incidents were part of the systematic failure by AmerisourceBergen, including dramatically understaffing and underfunding its compliance programs,” Philip Sellinger, U.S. attorney for the District of New Jersey, said during the press call. “In one year, AmerisourceBergen spent more on taxicabs and office supplies than on the Controlled Substances Act compliance budget.”

In a statement, AmerisourceBergen said the lawsuit represented an attempt to “shift the onus of interpreting and enforcing the law from the Department of Justice and Drug Enforcement Administration (DEA) to an industry they are tasked with regulating and policing.”

The five pharmacies were “cherrypicked” by the DOJ out of thousands the company serves, the statement said.

AmerisourceBergen is one of three major U.S. pharmaceutical distributors. The other two are McKesson and Cardinal Health.

In February the companies, along with pharmaceutical manufacturer Johnson & Johnson, agreed to pay $26 billion to settle thousands of civil lawsuits brought by state and local governments. Most of the money will go toward treatment and prevention.

The U.S. drug epidemic has killed more than 1 million people since 1999, according to the U.S. Centers for Disease Control and Prevention.

Opioids are the main driver of U.S. drug overdose deaths. Of an estimated 108,000 drug overdose deaths reported in the country last year, 81,000 involved opioids such as fentanyl, according to the CDC.

For many outside China, this was the year that the term “surveillance state” became something they understood.

Western media reported in April on what were thought to be government-operated drones whirring through a locked-down Shanghai, China’s most populous city, where authorities reported a record 22,000 new cases of COVID-19 on a single day. In an unverified viral video, one drone trumpeted, “Control your soul’s desire for freedom” as it hovered over a housing compound at night.

Citizens were expected to download a “health code” app for smartphones that dictated their activities. Designed to curtail the spread of the virus, a green QR code meant freedom to move around. A red code barred movement.

In the city of Zhengzhou, authorities in June allegedly issued red codes, usually sent to people deemed by authorities to be at high risk of infection or already infected, to people heading to town to protest a local bank that was freezing their assets.

At the end of November, when unprecedented protests against the “zero-COVID” policy erupted nationwide, Western media reported that authorities began checking the smartphones of people near the demonstrations, looking for VPN software that allowed them access to sites and social platforms like Twitter beyond China’s “Great Firewall.”

By mid-December, the U.S. Congress had passed legislation to restrict the use of the Chinese-owned social media app TikTok. Wildly effective for spreading dancing baby videos and political messaging both real and fake, the lawmakers had security concerns about the data Beijing might be collecting from millions of users as each video played.

According to University of Virginia professor Aynne Kokas, who wrote the book “Trafficking Data: How China is Winning the Battle for Digital Sovereignty,” Beijing’s strict zero-COVID response to the pandemic played a big role in showing the rest of the world what surveillance in China is like, including targeting dissidents.

“China’s handling of its zero-COVID policy and the enhancement of surveillance in China in order to achieve that zero-COVID policy has amplified global popular understanding of the scope and scale of China’s surveillance tech,” she told VOA Mandarin in an interview.

Many ways to watch

Street cameras are the primary mode of surveillance, with more than half of the world’s nearly 1 billion surveillance cameras located in China.

In addition to picking people out of crowds, surveillance cameras “aim to transform ‘unstructured information’ into ‘structured information,’ turning a chaotic visual field into something akin to a text file that can be easily, automatically analyzed, and searched,” according to an October report from Human Rights Watch.

Surveillance also includes the collection of biometric data, like voice samples, DNA, iris scans and gait “to form a multimodal portrait,” according to the HRW report. Forced biometric data collection has been tied to repression in Xinjiang and Tibet.

Chinese companies have supplied AI surveillance technology to 63 countries, 36 of which have signed onto China’s Belt and Road Initiative, according to a 2019 report from the Carnegie Endowment for International Peace.

In China’s northwestern region of Xinjiang, where the government has launched a crackdown against Uyghurs, the big data system known as the Integrated Joint Operations Platform, or IJOP, closely tracks behaviors Beijing deems suspicious — such as avoiding neighbors or stopping cell phone use — and flags the individuals for interrogation.

Maintaining control, order

But the real effect of this sweeping surveillance system is social control, according to Maya Wang, associate director in the Asia division at HRW.

“IJOP is promoted as an anti-terrorism system, but if you study it carefully, anti-terrorism is not its real purpose,” said Wang. “The system uses variables such as whether someone goes to the gas station or how often their phone is turned off to measure suspicious behavior. Systems like IJOP are ineffective as anti-terrorism mechanisms.”

Beyond Xinjiang, in other parts of China, the government often promotes surveillance technology as a way to maintain social order, according to Bulelani Jili, a doctoral candidate at Harvard University studying Chinese technology.

“The CCP is always framing surveillance technologies as part of its needs and ambitions for political stability,” he told VOA Mandarin in an interview. “Both the promotion and application of surveillance technology has really been about ensuring political stability.”

But when China began experiencing unprecedented protests around the country late last month from people fed up with Beijing’s strict pandemic protocols, authorities employed that technology to locate protestors who believed they’d taken steps to hide themselves from the ubiquitous monitoring.

HRW China researcher Yaqiu Wang said the backlash against the zero-COVID policy and against the security forces that kept people from protesting outside banks in Henan and Anhui show that people are increasingly questioning Beijing’s positive stance on the use of surveillance technology.

TikTok restrictions

The final month of 2022 has seen a flurry of steps taken by Taiwan and the United States to restrict the use of TikTok due to security concerns posed by the Chinese-owned social media app.

In early December, Taiwan announced that government workers would be restricted from using TikTok on government devices. Then on December 18, Taiwan’s government announced it had opened a probe into TikTok on suspicion of illegally operating a subsidiary on the island.

In the U.S., 19 of its 50 states have at least partially blocked access to TikTok on government devices, with most of those restrictions coming in the past few weeks. The U.S. Senate also passed a bill December 14 that would ban federal employees from using TikTok on government devices.

These moves are signs of growing concern over the surveillance threats that TikTok poses outside China, analysts said, and more broadly, how the Chinese government uses technology to monitor people within China’s borders.

“One could see a situation where a staffer in the House or Senate would be using TikTok for entertainment purposes, but then that app could also monitor their other communications,” UVA’s Kokas said in an interview with VOA Mandarin. “When we’re talking about government phones, or government devices, those risks become even more elevated.”

Kokas said TikTok has the capacity to pose a number of national security threats, including spreading misinformation and disinformation. Gathering consumer data from TikTok also gives China a competitive advantage to build better products for the global marketplace.

At a regular press conference in November, Chinese Foreign Ministry spokesperson Mao Ning rebutted the allegations about TikTok, saying that accusations of “spreading false information and using it as an excuse to suppress relevant Chinese companies has become a common practice in the United States.”

Restricting the use of TikTok on government devices is logical to Kokas, but she cautioned that it is not a panacea.

“This isn’t going to solve Chinese consumer data gathering in the U.S. by any means,” she said. But “a TikTok ban for general users doesn’t make a lot of sense. We need a more expansive data security regime in the U.S.”

The United States earlier this month announced a contract worth up to $29 million to clean up dioxin contamination at the Bien Hoa Air Base in southern Vietnam, near Ho Chi Minh City, a consequence of U.S. use of the herbicide Agent Orange during the Vietnam War.

The move is the most recent attempt to demonstrate cooperation between the two countries despite a still complicated relationship. 

The nations now work together on trade issues, climate change, and legacies of the war, such as the dioxin spraying or the so-called Christmas bombings, 50 years ago this month, when America dropped 20,000 tons of bombs on Hanoi and Haiphong. 

“This announcement represents the United States’ commitment to our partnership with Vietnam,” Aler Grubbs, the Hanoi-based Vietnam mission director for the U.S. Agency for International Development, said. “This contract will complete critical preparatory work, paving the way for the treatment phase of the project.” 

Some differences still remain between the United States and Vietnam, ranging from human rights to Bien Hoa itself, where the two have not been able to come to an agreement on a cemetery for former soldiers of South Vietnam, with which the U.S. was allied against communist North Vietnam in the war that ended in 1975 with a North Vietnamese victory.

USAID said it finished a similar project in 2018 to clean up Agent Orange and other chemicals that it sprayed around Da Nang in central Vietnam to defoliate the jungle used by communist forces to hide during the war. It said compared to Da Nang, Bien Hoa would require dealing with four times as much soil that has been contaminated with the chemicals, still linked to birth defects. 

Similarly, samples of tilapia fish collected in Bien Hoa in 2010 continued to show levels of Agent Orange considered to be unhealthy, according to a report from the Vietnamese Ministry of Natural Resources and Environment and the United Nations Development Program.

“We look forward to applying our specialized expertise to meet the project’s high safety and health requirements and technical specifications, and contribute to the overall success of the project,” said Vu Van Liem, general director of VINA E&C Investment and Construction JSC, the local corporation that has received the contract to excavate the soil and prepare it for treatment over a period of four years.

Both the U.S. and Vietnamese governments are participating in the entire cleanup across the country, which is estimated will require more than 10 years at a cost of approximately $450 million. Washington said it expects to spend $300 million in the end and has allocated more than $163 million so far.

The two nations have come a long way since the war, though they continue to have issues of disagreement. America has applied pressure on the autocratic government of Vietnam on a routine basis to recognize the freedom of speech and to release political prisoners while Hanoi denies it has any. 

In one of the more recent developments, for example, the U.S. Secretary of State Antony J. Blinken said December 2 that Vietnam would be put on a “Special Watch List for engaging in or tolerating severe violations of religious freedom,” along with Algeria, the Central African Republic, and Comoros.

“Countries that effectively safeguard [religion] and other human rights are more peaceful, stable, prosperous and more reliable partners of the United States than those that do not,” he said.

“We will continue to carefully monitor the status of freedom of religion or belief in every country around the world and advocate for those facing religious persecution or discrimination.”

Vietnam’s Foreign Affairs Ministry did not accept being put on the watch list.

“Recently Vietnam has been finalizing the legal system and the policies on religion and belief,” the ministry said in response on December 15.

“These efforts and achievements in ensuring freedom of religion and beliefs have been widely recognized by the international community.”

However, while Washington was pressuring Vietnam on one problem, it was also trying to solve another. The Agent Orange remediation in Bien Hoa was about more than cleaning up a mess decades after war. It was also about looking toward the decades to come, showing closer cooperation, such as potentially on addressing environmental problems in the future.

“This marks the largest contract yet by USAID to a local Vietnamese organization,” Grubbs said, “as we make a concerted effort to build Vietnamese expertise in this nascent area of environmental health and safety.”

Countries are imposing or considering imposing curbs on travelers from China amid a COVID-19 surge there after authorities relaxed “zero-COVID” rules.

They cite a lack of information from China on variants and are concerned about a wave of infections. China has rejected criticism of its COVID data and said it expects future mutations to be potentially more transmissible but less severe.

Below is a list of new regulations for travelers from China.

Countries Imposing Curbs

United States

The U.S. will impose mandatory COVID-19 tests on travelers from China beginning Jan. 5. All air passengers 2 and older will require a negative result from a test no more than two days before departure from China, Hong Kong or Macau. The Centers for Disease Control and Prevention also said Americans should also reconsider travel to China, Hong Kong and Macau.

India

The country has mandated a COVID-19 negative test report for travelers arriving from China, Japan, South Korea, Hong Kong and Thailand, the health minister said. Passengers from those countries will be quarantined if they show symptoms or test positive.

Japan

Japan will require a negative COVID-19 test upon arrival for travelers from mainland China. Those who test positive will be required to quarantine for seven days. New border measures for China will go into effect at midnight Friday. The government will also limit requests from airlines to increase flights to China.

Italy

Italy has ordered COVID-19 antigen swabs and virus sequencing for all travelers coming from China. Milan’s main airport, Malpensa, had already started testing passengers arriving from Beijing and Shanghai. “The measure is essential to ensure surveillance and detection of possible variants of the virus in order to protect the Italian population,” Health Minister Orazio Schillaci said.

Taiwan

Taiwan’s Central Epidemic Command Centre said all passengers on direct flights from China, as well as by boat at two offshore islands, will have to take PCR tests upon arrival, starting Sunday.

Countries Monitoring Situation

Australia

Prime Minister Anthony Albanese said Australia was continuing to monitor the situation in respect of China “as we continue to monitor the impact of COVID here in Australia as well as around the world.”

Philippines

The Southeast Asian country is being “very cautious” and could impose measures such as testing requirements on visitors from China, but not an outright ban, Transportation Secretary Jaime Bautista said.

Not Considering Curbs

Britain

Britain has no plans to bring back COVID-19 testing for those coming into the country, a government spokesperson said Thursday, when asked about a Daily Telegraph report saying it would consider curbs for arrivals from China.

NASA is exploring whether SpaceX’s Crew Dragon spacecraft can potentially offer an alternative ride home for some crew members of the International Space Station after a Russian capsule sprang a coolant leak while docked to the orbital lab.

NASA and Russia’s space agency, Roscosmos, are investigating the cause of a punctured coolant line on an external radiator of Russia’s Soyuz MS-22 spacecraft, which is supposed to return its crew of two cosmonauts and one U.S. astronaut to Earth early next year.

But the December 14 leak, which emptied the Soyuz of a vital fluid used to regulate crew cabin temperatures, has derailed Russia’s space station routines, with engineers in Moscow examining whether to launch another Soyuz to retrieve the three-man team that flew to ISS aboard the crippled MS-22 craft.

If Russia cannot launch another Soyuz ship, or decides for some reason that doing so would be too risky, NASA is weighing another option.

“We have asked SpaceX a few questions on their capability to return additional crew members on Dragon if necessary, but that is not our prime focus at this time,” NASA spokeswoman Sandra Jones said in a statement to Reuters.

SpaceX did not respond to a Reuters request for comment.

It was unclear what NASA specifically asked of SpaceX’s Crew Dragon capabilities, such as whether the company can find a way to increase the crew capacity of the Dragon currently docked to the station, or launch an empty capsule for the crew’s rescue.

But the company’s potential involvement in a mission led by Russia underscores the degree of precaution NASA is taking to ensure its astronauts can safely return to Earth, should one of the other contingency plans arranged by Russia fall through.

The leaky Soyuz capsule ferried U.S. astronaut Frank Rubio and cosmonauts Sergey Prokopyev and Dimitri Petelin to the space station in September for a six-month mission. They were scheduled to return to Earth in March 2023.

The station’s four other crew members — two more from NASA, a third Russian cosmonaut and a Japanese astronaut — arrived in October via a NASA-contracted SpaceX Crew Dragon capsule, which also remains parked at the ISS.

SpaceX’s Crew Dragon capsule, a gumdrop-shaped pod with four astronaut seats, has become the centerpiece to NASA’s human spaceflight efforts in low-Earth orbit. Besides Russia’s Soyuz program, it is the only entity capable of ferrying humans to the space station and back.

Three possible culprits

Finding what caused the leak could factor into decisions about the best way to return the crew members. A meteroid-caused puncture, a strike from a piece of space debris or a hardware failure on the Soyuz capsule itself are three possible causes of the leak that NASA and Roscosmos are investigating.

A hardware malfunction could raise additional questions for Roscosmos about the integrity of other Soyuz vehicles, such as the one it might send for the crew’s rescue, said Mike Suffredini, who led NASA’s ISS program for a decade until 2015.

“I can assure you that’s something they’re looking at, to see what’s back there and whether there’s a concern for it,” he said. “The thing about the Russians is they’re really good at not talking about what they’re doing, but they’re very thorough.”

Roscosmos chief Yuri Borisov had previously said engineers would decide by Tuesday how to return the crew to Earth, but the agency said that day it would make the decision in January.

NASA has previously said the capsule’s temperatures remain “within acceptable limits,” with its crew compartment currently being vented with air flow allowed through an open hatch to the ISS.

Sergei Krikalev, Russia’s chief of crewed space programs, told reporters last week that the temperature would rise rapidly if the hatch to the station were closed.

NASA and Roscosmos are primarily focusing on determining the leak’s cause, Jones said, as well as the health of MS-22 which is also meant to serve as the three-man crew’s lifeboat in case an emergency on the station requires evacuation.

A recent meteor shower initially seemed to raise the odds of a micrometeoroid strike as the culprit, but the leak was facing the wrong way for that to be the case, NASA’s ISS program manager Joel Montalbano told reporters last week, though a space rock could have come from another direction.

And if a piece of space debris is to blame, it could fuel concerns of an increasingly messy orbital environment and raise questions about whether such vital equipment as the spacecraft’s coolant line should have been protected by debris shielding, as other parts of the MS-22 spacecraft are.

“We are not shielded against everything throughout the space station,” Suffredini said. “We can’t shield against everything.”
