TAIPEI, Taiwan — China is preparing to launch a lunar probe Friday that would land on the far side of the moon and return with samples that could provide insights into geological and other differences between the less-explored region and the better-known near side.

The unprecedented mission would be the latest advance in the increasingly sophisticated and ambitious space exploration program that is now competing with the U.S., still the leader in space. China already landed a rover on the moon’s far side in 2019, the first country to do so.

Free from exposure to Earth and other interference, the moon’s somewhat mysterious far side is ideal for radio astronomy and other scientific work. Because the far side never faces Earth, a relay satellite is needed to maintain communications.

The Chang’e lunar exploration probe is named after the Chinese mythical moon goddess.

The probe is being carried on a Long March-5 YB rocket set for liftoff Friday evening from the Wenchang launch center on the southern tropical island province of Hainan, the China National Space Administration announced. The launch window is 5-6 p.m. with the target of 5:27 p.m.

Huge numbers of people crowded Hainan’s beaches to view the launch, which comes in the middle of China’s five-day May Day holiday.

After orbiting the moon to reduce speed, the lander will separate from the spacecraft and begin scooping up samples almost as soon as it sets down. It will then reconnect with the returner for the trip back to Earth. The entire mission is set to last 53 days.

China in 2020 returned samples from the moon’s near side, the first time anyone has done so since the U.S. Apollo program that ended in the 1970s. Analysis of the samples found they contained water in tiny beads embedded in lunar dirt.

Also in the past week, three Chinese astronauts returned home from a six-month mission on the country’s orbiting space station after the arrival of its replacement crew.

China built its own space station after being excluded from the International Space Station, largely because of U.S. concerns over the Chinese military’s total control of the space program amid a sharpening competition in technology between the two geopolitical rivals. U.S. law bars almost all cooperation between the U.S. and Chinese space programs without explicit congressional approval.

China’s ambitious space program aims to put astronauts on the moon by 2030, as well as bring back samples from Mars around the same year and launch three lunar probe missions over the next four years. The next is scheduled for 2027.

Longer-term plans call for a permanent crewed base on the lunar surface, although those appear to remain in the conceptual phase.

China conducted its first crewed space mission in 2003, becoming the third country after the former Soviet Union and the U.S. to put a person into space using its own resources.

The three-module Tiangong, much smaller than the ISS, was launched in 2021 and completed 18 months later. It can accommodate up to six astronauts at a time and is mainly dedicated to scientific research. The crew will also install space debris protection equipment, carry out payload experiments, and beam science classes to students on Earth.

China has also said that it eventually plans to offer access to its space station to foreign astronauts and space tourists. With the ISS nearing the end of its useful life, China could eventually be the only country or corporation to maintain a crewed station in orbit.

The U.S. space program is believed to still hold a significant edge over China’s due to its spending, supply chains and capabilities.

The U.S. aims to put a crew back on the lunar surface by the end of 2025 as part of a renewed commitment to crewed missions, aided by private sector players such as SpaceX and Blue Origin. They plan to land on the moon’s south pole where permanently shadowed craters are believed to be packed with frozen water.

phoenix — Democratic Arizona Governor Katie Hobbs has relegated a Civil War-era ban on most abortions to the past by signing a bill Thursday to repeal it. 

Hobbs said the move was just the beginning of a fight to protect reproductive health care in Arizona. The repeal of the 1864 law that the state Supreme Court recently reinstated won’t take effect until 90 days after the legislative session ends, which typically happens in June or July. 

Abortion rights advocates say they’re hopeful a court will step in to prevent what could be a confusing landscape of access for girls and women across Arizona as laws are introduced and then reversed. 

The effort to repeal the long-dormant law, which bans all abortions except those done to save a patient’s life, won final legislative approval Wednesday in a 16-14 vote of the Senate, as two GOP lawmakers joined with Democrats. 

Hobbs denounced “a ban that was passed by 27 men before Arizona was even a state, at a time when America was at war over the right to own slaves, a time before women could even vote.” 

“This ban needs to be repealed, I said it in 2022 when Roe was overturned, and I said it again and again as governor,” Hobbs said during the bill signing. 

In early April, Arizona’s Supreme Court voted to restore the 1864 law that provides no exceptions for rape or incest and allows abortions only if the mother’s life is in jeopardy. The majority opinion suggested doctors could be prosecuted and sentenced to up to five years in prison if convicted. 

Democrats, who are the minority in the Legislature, struck back with the help of a handful of Republicans in the House and Senate to advance a repeal in a matter of weeks to Hobbs’ desk. 

A crowd of lawmakers — mostly women — joined in the signing ceremony with celebratory airs, including taking selfies and exchanging congratulations among Democrats. 

The scene stood in sharp contrast to Wednesday’s vote in the Senate that extended for hours as Republicans described their motivations in personal, emotional and even biblical terms — including graphic descriptions of abortion procedures and amplified audio recordings of a fetal heartbeat. 

Meanwhile, across the country, an abortion rights initiative in South Dakota submitted far more signatures than required to make the ballot this fall. In Florida, a ban took effect against most abortions after six weeks of pregnancy, before many people even know they are pregnant. 

In Arizona, once the repeal takes effect in the fall, a 2002 statute banning abortion after 15 weeks of pregnancy will become the state’s prevailing abortion law. 

Whether the 1864 law will be enforced in the coming months depends on who is asked. The anti-abortion-rights group defending the ban, Alliance Defending Freedom, maintains county prosecutors can begin enforcing it once the Supreme Court’s decision becomes final, which hasn’t yet occurred. 

Planned Parenthood Arizona filed a motion Wednesday asking the court to prevent a pause in abortion services until the repeal takes effect. Democratic Attorney General Kris Mayes has joined in that action. 

The Supreme Court set deadlines next week for briefings on the motion.

WASHINGTON — Hackers who breached UnitedHealth’s tech unit in February potentially stole data from a third of Americans, the largest U.S. health insurer’s CEO told a congressional committee on Wednesday.

Two congressional panels grilled CEO Andrew Witty about the cyberattack on the company’s Change Healthcare unit, which processes around 50% of all medical claims in the U.S.

The breach has caused widespread disruptions in claims processing, impacting patients and providers across the country.

Witty fielded heated questions from House Energy and Commerce Committee members about the company’s failure to prevent the breach and contain its fallout.

Pressed for details on the data compromised, Witty said protected health information and personally identifiable information pertaining to “maybe a third” of Americans was stolen.

“We continue to investigate the amount of data involved here,” he added. “We do think it’s going to be substantial.”

The cybercriminal gang AlphV hacked into Change on Feb. 12 using stolen login credentials on an older server that did not have multifactor authentication, Witty said.

“It was … a platform which had only recently become part of the company was in the process of being upgraded,” Witty said, referring to UnitedHealth’s $13 billion acquisition of Change in 2022.

The platform also did not have the security measures prescribed in a joint alert issued by the FBI and U.S. cyber and health officials in December 2023 to specifically warn about AlphV, or BlackCat, targeting healthcare organizations.

UnitedHealth paid the gang around $22 million in bitcoin as ransom, Witty said, adding that however there was no guarantee that the breached data was secure and could not still be leaked. Another hacking group claiming to be an offshoot of AlphV said last month it had a copy of the data, though the company has not verified that claim.

The Senate Finance Committee probed the outsized influence of UnitedHealth – which has a market capitalization of $445 billion and annual revenue of $372 billion – on American health care. But Witty said the company’s problems were not a threat to the broader economy.

Senator Bill Cassidy said senators on the panel “would have to ask, is the dominant role of United too dominant because it is into everything and messing up United messes up everybody?”

“My point is, the size of United becomes a it’s almost a too big to fail and sure, because if it fails, it’s going to bring down far more than it ordinarily would,” Cassidy said.

Witty said in response, “I don’t believe it is because actually despite our size, for example, we have no hospitals in America, we do not own any drug manufacturers.”

Yet, Change processes medical claims for around 900,000 physicians, 33,000 pharmacies, 5,500 hospitals and 600 laboratories in the U.S.

U.S. military members’ data was also stolen in the hack, Witty revealed, without saying how many of them were impacted.

Senate Finance Committee Chairman Ron Wyden called the hack a national security threat.

“I believe the bigger the company, the bigger the responsibility to protect its systems from hackers. UHG was a big target long before it was hacked,” he added.

“UnitedHealth Group has not revealed how many patients’ private medical records were stolen, how many providers went without reimbursement, and how many seniors are unable to pick up their prescriptions as a result of the hack,” said Wyden.

In letters to both congressional committees, the American Hospital Association said an internal survey of its members found that 94% of hospitals reported damage to cash flow, and more than half reported “significant or serious” financial damage due to Change’s inability to process claims.

Similarly, 90% of respondents to an American Medical Association survey of doctors said they continue to lose revenue because of the hack, according to the group’s written testimony to the Senate Finance Committee.

The average income of people around the world will be cut by one-fifth because of climate change by the middle of the century, according to a new report by Germany’s Potsdam Institute for Climate Impact Research, published in the journal Nature. Henry Ridgwell has more.
…

London — Climate change will cut the average income of people around the world by one-fifth by 2050, according to a new report published in the journal Nature by the Potsdam Institute for Climate Impact Research.

As many parts of the world experience extreme weather, the global impacts of a changing climate are set to cost $38 trillion a year by the middle of the century, the report warns — a reduction in the world’s average income of some 19%.

The losses are already locked in, independent of future emission choices, the report says.

Maximilian Kotz, co-author of the report, told VOA there is little the world can do to mitigate the impact.

“What we find is that over the next 25 to 30 years, impacts on the economy are consistent across different emissions scenarios, regardless of whether we enter a high-emission or low-emission world,” he said.

Climate change, and especially higher temperatures, have been shown to impact worker productivity, said Kotz.

“That’s then going to be manifest across numerous different industries — although it’s particularly strong, those impacts, when workers are outdoors, so in contexts like manufacturing sectors,” he said. “And then, we also know that impacts on agricultural productivity are very strong from again, particularly high temperatures.”

The research looked at climate and economic data from the past 40 years from more than 1,600 regions across the world and used it to assess future impacts. Those least responsible for global emissions are likely to be worst hit.

“Committed losses are projected for all regions except those at very high latitudes, at which reductions in temperature variability bring benefits. The largest losses are committed at lower latitudes in regions with lower cumulative historical emissions and lower present-day income,” the report said.

The authors conclude that tackling climate change would be far cheaper than putting up with the economic damage and estimate the cost of reducing greenhouse gas emissions would be just one-sixth of the $38 trillion impact of climate change by 2050.

The research is likely to underestimate the total economic impact of climate change.

“Important channels such as impacts from heatwaves, sea-level rise, tropical cyclones and tipping points, as well as non-market damages such as those to ecosystems and human health, are not considered in these estimates,” the report said.

BEIJING — The first scientist to publish a sequence of the COVID-19 virus in China said he was allowed back into his lab after he spent days locked outside, sitting in protest.

Zhang Yongzhen wrote in an online post on Wednesday, just past midnight, that the medical center that hosts his lab had “tentatively agreed” to allow him and his team to return and continue their research for the time being.

“Now, team members can enter and leave the laboratory freely,” Zhang wrote in a post on Weibo, a Chinese social media platform. He added that he is negotiating a plan to relocate the lab in a way that doesn’t disrupt his team’s work with the Shanghai Public Health Clinical Center, which hosts Zhang’s lab.

Zhang and his team were suddenly told they had to leave their lab for renovations on Thursday, setting off the dispute, he said in an earlier post that was later deleted. On Sunday, Zhang began a sit-in protest outside his lab after he found he was locked out, a sign of continuing pressure on Chinese scientists conducting research on the coronavirus.

Zhang sat outside on flattened cardboard in drizzling rain, and members of his team unfurled a banner that read “Resume normal scientific research work,” pictures posted online show. News of the protest spread widely on Chinese social media, putting pressure on local authorities.

In an online statement Monday, the Shanghai Public Health Clinical Center said that Zhang’s lab was closed for “safety reasons” while being renovated. It added that it had provided Zhang’s team an alternative laboratory space.

But Zhang responded the same day his team wasn’t offered an alternative until after they were notified of their eviction, and the lab offered didn’t meet safety standards for conducting their research, leaving his team in limbo.

Zhang’s dispute with his host institution was the latest in a series of setbacks, demotions and ousters since the virologist published the sequence in January 2020 without state approval.

Beijing has sought to control information related to the virus since it first emerged. An Associated Press investigation found that the government froze domestic and international efforts to trace it from the first weeks of the outbreak. These days, labs are closed, collaborations shattered, foreign scientists forced out and some Chinese researchers barred from leaving the country.

Zhang’s ordeal started when he and his team decoded the virus on Jan. 5, 2020, and wrote an internal notice warning Chinese authorities of its potential to spread — but did not make the sequence public. The next day, Zhang’s lab was ordered to close temporarily by China’s top health official, and Zhang came under pressure from authorities.

Foreign scientists soon learned that Zhang and other Chinese scientists had deciphered the virus and called on China to release the sequence. Zhang published it on Jan. 11, 2020, despite a lack of permission from Chinese health officials.

Sequencing a virus is key to the development of test kits, disease control measures and vaccinations. The virus eventually spread to every corner of the world, triggering a pandemic that disrupted lives and commerce, prompted widespread lockdowns and killed millions of people.

Zhang was awarded prizes overseas in recognition for his work. But health officials removed him from a post at the Chinese Center for Disease Control and Prevention and barred him from collaborating with some of his former partners, hindering his research.

Still, Zhang retains support from some in the government. Though some of Zhang’s online posts were deleted, his sit-in protest was reported widely in China’s state-controlled media, indicating divisions within the Chinese government on how to deal with Zhang and his team.

“Thank you to my online followers and people from all walks of life for your concern and strong support over the past few days!” Zhang wrote in his post Wednesday.

NAIROBI, Kenya — Tourists were evacuated by air from Kenya’s Maasai Mara National Reserve Wednesday after more than a dozen hotels, lodges and camps were flooded as heavy rains continue to batter the country.

Tourist accommodation facilities were submerged after a river within the Maasai Mara broke its banks early Wednesday. The reserve, in southwestern Kenya, is a popular tourist destination because it features the annual wildebeest migration from the Serengeti in Tanzania.

The Kenya Red Cross said it rescued 36 people by air and 25 others by land. The Narok County government said it deployed two helicopters to carry out evacuations in the expansive conservation area.

More than 170 people have died across Kenya since mid-March when the rainy season started, causing flooding and landslides and destroying infrastructure. The Meteorology Department has warned that more rain is expected this week.

On Monday, a river broke through a clogged tunnel in the Mai Mahiu area in western Kenya, sweeping houses away and damaging roads. The incident killed 48 people, and more than 80 others were missing.

Search and rescue operations across the Mai Mahiu area are ongoing. President William Ruto on Tuesday ordered the military to join in the search.

Locals say rescue efforts have been slow due to lack of equipment to dig through the debris.

The government has urged people living in flood-prone areas to evacuate or be moved forcefully as water levels in two major hydroelectric dams rise to a “historic high.”
…

Mai Mahiu, Kenya — Kenyan President William Ruto on Tuesday deployed the military to evacuate everyone living in flood-prone areas in a nation where 171 people have been killed since March by torrential rains. 

Seasonal rains, amplified by the El Nino weather pattern, have devastated the East African nation, with floodwaters engulfing villages and threatening to unleash even more damage in the weeks to come. 

In the worst incident, which killed nearly 50 villagers, a makeshift dam burst in the Rift Valley before dawn Monday, sending a torrent of water and mud gushing down a hill and swallowing everything in its path. 

The tragedy in Kamuchiri village, Nakuru county, was the deadliest episode in the country since the start of the March-May rainy season. 

Ruto, who visited the victims of the Kamuchiri deluge after chairing a Cabinet meeting in Nairobi, said his government had drawn up a map of neighborhoods at risk of flooding. 

“The military has been mobilized, the national youth service has been mobilized, all security agencies have been mobilized to assist citizens in such areas to evacuate to avoid any dangers of loss of lives,” he said. 

People living in the affected areas will have 48 hours to move, he said. 

“The forecast is that rain is going to continue, and the likelihood of flooding and people losing lives is real. Therefore, we must take preemptive action,” Ruto said. 

“It is not a time for guesswork, we are better off safe than sorry.” 

The Kamuchiri disaster — which killed at least 48 people dead — cut off a road, uprooted trees and destroyed homes and vehicles. Some 26 people were hospitalized, Ruto said, with fears the death toll could rise as search and rescue operations continued. 

The Cabinet warned that two dams — Masinga and Kiambere — both less than 200 kilometers (125 miles) northeast of the capital, had “reached historic highs,” portending disaster for those downstream.  

“While the government encourages voluntary evacuation, all those who remain within the areas affected by the directive will be relocated forcibly in the interest of their safety,” a statement said. 

Monday’s tragedy came six years after a dam accident at Solai, also in Nakuru county, killed 48 people, sending millions of liters of muddy water raging through homes and destroying power lines. 

The May 2018 disaster involving a private reservoir on a coffee estate also followed weeks of torrential rains that sparked deadly floods and mudslides. 

Opposition politicians and lobby groups have accused Ruto’s government of being unprepared and slow to respond to the crisis despite weather warnings, demanding that it declare the floods a national disaster. 

Kenya’s main opposition leader, Raila Odinga, said Tuesday the authorities had failed to make “advance contingency plans” for the extreme weather. 

“The government has been talking big on climate change, yet when the menace comes in full force, we have been caught unprepared,” he said. “We have therefore been reduced to planning, searching and rescuing at the same time.” 

Environment Minister Soipan Tuya told a press briefing in Nairobi that the government was stepping up efforts to be better prepared for such events. 

“We continue to focus on the need to invest in early warning systems that prepare our population — days, weeks and months ahead of extreme weather events, such as the heavy rainfall we’re experiencing.”  

The international community, including the United Nations and African Union Commission chief Moussa Faki Mahamat, have sent condolences and pledged solidarity with the affected families. 

The weather has also left a trail of destruction in neighboring Tanzania, where at least 155 people have been killed in flooding and landslides. 

Late last year, more than 300 people died in rains and floods in Kenya, Somalia and Ethiopia, just as the region was trying to recover from its worst drought in four decades. 

El Nino is a naturally occurring climate pattern typically associated with increased heat worldwide, leading to drought in some parts of the world and heavy rains elsewhere.

Paris, France — G7 environment ministers committed on Tuesday to ramp up the production and deployment of battery storage technology, an essential component for increasing renewable energy and combating climate change.  

Here is how and why batteries play a vital role in the energy transition:   

Growing demand

Batteries have been central to the rise of electric vehicles (EVs) but are also critical to wind and solar power because of the intermittent nature of these energy sources.  

Surplus electricity must be stored in batteries to stabilize distribution regardless of peaks in demand, or breaks in supply at night or during low winds.   

Battery deployment in the energy sector last year increased more than 130 percent from 2022, according to a report released last week by the International Energy Agency (IEA).    

The main markets are China, the European Union and the United States. 

Following closely are Britain, South Korea, Japan and developing nations in Africa, where solar and storage technology is seen as the gateway to energy access.  

Six-fold goal

To triple global renewable energy capacity by 2030 — a goal set at the UN climate conference in December — the IEA says a six-fold increase in battery storage will be necessary.  

Clean energy is essential to reduce emissions from burning fossil fuels and to hope to keep the international target of restricting global warming to 1.5 degrees Celsius above pre-industrial levels.   

The total storage capacity required to achieve this target is an estimated 1,500 gigawatts by 2030.  

Of this, 1,200 GW will need to be supplied by batteries.

Cost challenges

In less than 15 years, the cost of batteries has fallen by 90 percent.  

“The combination of solar PV and batteries is today competitive with new coal plants in India. And just in the next few years, it will be cheaper than new coal in China and gas-fired power in the United States,” IEA chief Fatih Birol said last week.   

“But still the pace is not fast enough to reach our goals in terms of climate change and energy security.”  

Costs will have to come down further, he said, while calling for supply chains to be diversified.   

Most batteries are currently produced by China.   

But some 40 percent of planned battery manufacturing projects are in the United States and Europe, according to the IEA.   

If those projects are realized, they would be nearly sufficient to meet the needs of those countries.

Metal matters

Another thorny issue is the availability of critical metals like lithium and cobalt that are essential to make batteries.  

Experts say the development chemical alternatives could complement the dominant lithium-ion technology.  

“Transition in the technology will reduce the amount of lithium” needed, said Brent Wanner, head of the IEA’s power sector unit, adding, “this includes shifting to sodium-ion batteries.” 

Beyond 2030, high-density solid-state batteries that offer a longer lifespan are expected to become commercially available. 

There are other storage options, although not as widely applicable or available as batteries.

Pumped storage hydropower has long been used in the hydroelectric sector.

The transformation of electricity into hydrogen, which can be stored and transported, is a new technology expected to become more readily available. 

Be flexible

Renewable energy is not entirely reliant on storage and measures can be taken to improve the flexibility of its production to meet demands.   

Industry and governments are gearing up for the transition.   

The European Union’s Energy Regulators Agency called on member states in September to assess their “flexibility potential” based on estimates that renewables will need to double by 2030.   

Such a rise requires greater “flexibility” in grids, meaning energy can be stored and distributed consistently despite fluctuating production and demand.   

The G7 said Tuesday it would not only support more production and use of battery storage, but promote technological advancements in the sector as well as grid infrastructure.

SHANGHAI — The first scientist to publish a sequence of the COVID-19 virus in China staged a sit-in protest outside his lab after authorities locked him out of the facility — a sign of the Beijing’s continuing pressure on scientists conducting research on the coronavirus.

Zhang Yongzhen wrote in an online post Monday that he and his team had been suddenly notified they were being evicted from their lab, the latest in a series of setbacks, demotions and ousters since the virologist published the sequence in January 2020 without state approval.

When Zhang tried to go to the lab over the weekend, guards barred him from entering. In protest, he sat outside on flattened cardboard in drizzling rain, pictures from the scene posted online show. News of the protest spread widely on Chinese social media and Zhang told a colleague he slept outside the lab — but it was not clear Tuesday if he remained there.

“I won’t leave, I won’t quit, I am pursuing science and the truth!” he wrote in a post on Chinese social media platform Weibo that was later deleted.

In an online statement, the Shanghai Public Health Clinical Center said that Zhang’s lab was being renovated and was closed for “safety reasons.” It added that it had provided Zhang’s team an alternative laboratory space.

But Zhang wrote online that his team wasn’t offered an alternative until after they were notified of their eviction, and that the lab offered didn’t meet safety standards for conducting their research, leaving his team in limbo.

Zhang’s latest difficulty reflects how China has sought to control information related to the virus: An Associated Press investigation found that the government froze meaningful domestic and international efforts to trace it from the first weeks of the outbreak. That pattern continues to this day, with labs closed, collaborations shattered, foreign scientists forced out and Chinese researchers barred from leaving the country.

When reached by phone on Tuesday, Zhang said it was “inconvenient” for him to speak, saying there were other people listening in. In an email Monday to collaborator Edward Holmes seen by AP, Zhang confirmed he was sleeping outside his lab after guards barred him from entering.

An AP reporter was blocked by a guard at an entrance to the compound housing Zhang’s lab. A staff member at the National Health Commission, China’s top health authority, said by phone that it was not the main department in charge and referred questions to the Shanghai government. The Shanghai government did not immediately respond to a request for comment.

Zhang’s ordeal started when he and his team decoded the virus on Jan. 5, 2020, and wrote an internal notice warning Chinese authorities of its potential to spread — but did not make the sequence public. The next day, Zhang’s lab was ordered temporarily shut by China’s top health official, and Zhang came under pressure by Chinese authorities.

Around the time, China had reported several dozen people were being treated for a respiratory illness in the central city of Wuhan. Possible cases of the same illness had been reported in Hong Kong, South Korea and Taiwan involving recent travelers to the city.

Foreign scientists soon learned that Zhang and other Chinese scientists had deciphered the virus and called for him to publish. Zhang published his sequence of the coronavirus on Jan. 11, 2020, despite a lack of government permission.

Sequencing a virus is key to the development of test kits, disease control measures and vaccinations. The virus eventually spread to every corner of the world, triggering a pandemic that disrupted lives and commerce, prompted widespread lockdowns and killed millions of people.

Zhang was later awarded prizes in recognition for his work.

But Zhang’s publication of the sequence also prompted additional scrutiny of his lab, according to Holmes, Zhang’s collaborator and a virologist at the University of Sydney. Zhang was removed from a post at the Chinese Center for Disease Control and Prevention and barred from collaborating with some of his former partners, crippling his research.

“Ever since he defied the authorities by releasing the genome sequence of the virus that causes COVID-19 there has been a campaign against him,” Holmes said. “He’s been broken by this process and I’m amazed he has been able to work at all.”

geneva — Countries trying to negotiate a new global agreement on combating future pandemics began bridging their differences Monday, but they’re racing against time to seal a deal. 

The 194 nations in the World Health Organization are back at its Geneva headquarters for one last round of negotiations, after a two-year effort to secure a landmark accord on pandemic prevention, preparedness and response overran last month’s deadline.  

Issued with a new, slimmed-down draft text that kicks some of the tougher topics down the road, countries began going through its 37 articles in turn.  

However, the handful of articles opened Monday were still being negotiated as the day’s session was ending, with side discussion groups trying to come up with solutions.  

“It’s going as was to be expected. Most member states indicated that with this new text we are on the right track, but at the same time there are still a lot of things that need to be addressed,” talks co-chair Roland Driece told AFP.  

“The process is very time-consuming, and time is our biggest enemy,” the Dutch health diplomat said. “There are outstanding issues which are complicated — but time is not our friend.” 

Sting of COVID 

The goal of the talks, which last 12 hours a day and run until May 10, is to get an agreement ready for adoption at the WHO’s annual assembly of member states, which starts May 27.  

In December 2021, the raw sting of COVID-19 — which shredded economies, crippled health systems and killed millions — motivated countries to seek a binding framework of commitments aimed at preventing another such disaster.  

But big differences quickly emerged on how to go about it.  

The main disputes revolve around access and equity: access to pathogens detected within countries; access to pandemic-fighting products such as vaccines produced from that knowledge; and equitable distribution of not only counterpandemic tests, treatments and vaccinations but the means to produce them.

The new draft focuses on setting up the basic framework and pushes some of the trickier details into further talks running into 2026, notably on how the planned WHO Pathogen Access and Benefit-Sharing (PABS) System will work in practice.  

Clash of narratives   

One senior figure in the negotiations said there was a positive spirit, but that needed to be translated into “concrete action.” Another said the talks were “in the swing now,” with movement expected Tuesday.  

Nongovernmental organizations following the talks at WHO headquarters said it was difficult to read how they were progressing.  

“We’re witnessing a clash of narratives: We are either near the collapse, or the light at the end of the tunnel,” Jaume Vidal, senior policy adviser with Health Action International, told AFP.  

“I was convinced that the situation was worse than it seems,” Vidal said. “Discussions are taking place — that’s already a step forward — but we’re still missing some specific steps. We need public commitments on some of the articles.” 

African unity 

Alongside the African group, the Group for Equity bloc of countries is trying to ensure developing nations are not cut adrift again when it comes to accessing vaccines, tests and treatments. 

African Union health ministers released a statement Monday committing to getting “legal certainty for both users and providers” from the PABS system.  

“Africa stands ready to play its part and commits to engage actively in the ongoing negotiations,” the ministers said, following a meeting in Addis Ababa. 

They called for an international financing mechanism with explicit new, sustainable and increased funding from developed countries for pandemic preparedness and response. 

Indonesia has been a key player in the Group for Equity. 

Wiku Adisasmito, one of Indonesia’s lead negotiators at the Geneva talks, said both parts of the PABS system — having quick access to detected pathogens, and sharing the resulting benefits, such as vaccines — needed to be on an equal footing. 

“That’s key, not only for Indonesia but for most developing countries,” he told AFP. 

“All countries are not equal in terms of capacity, and the pathogens are only coming from hot spots,” he said, explaining that developing countries needed financial support to ramp up their surveillance for emerging dangerous pathogens in animals and the environment. 

If the talks needed an even greater reminder of urgency, the WHO has raised  alarm in recent weeks about the exponential growth of H5N1 bird flu, with concerns about what could happen if it starts being transmitted between humans.

HARARE — From ancient fertilizer methods in Zimbabwe to new greenhouse technology in Somalia, farmers across the heavily agriculture-reliant African continent are looking to the past and future to respond to climate change.

Africa, with the world’s youngest population, faces the worst effects of a warming planet while contributing the least to the problem. Farmers are scrambling to make sure the booming population is fed.

With more than 60% of the world’s uncultivated land, Africa should be able to feed itself, some experts say. And yet three in four people across the continent cannot afford a healthy diet, according to a report last year by the African Union and United Nations agencies. Reasons include conflict and lack of investment.

In Zimbabwe, where the El Nino phenomenon has worsened a drought, small-scale farmer James Tshuma has lost hope of harvesting anything from his fields. It’s a familiar story in much of the country, where the government has declared a $2 billion state of emergency and millions of people face hunger.

But a patch of green vegetables is thriving in a small garden the 65-year-old Tshuma is keeping alive with homemade organic manure and fertilizer. Previously discarded items have again become priceless.

“This is how our fathers and forefathers used to feed the Earth and themselves before the introduction of chemicals and inorganic fertilizers,” Tshuma said.

He applies livestock droppings, grass, plant residue, remains of small animals, tree leaves and bark, food scraps and other biodegradable items like paper. Even the bones of animals that are dying in increasing numbers due to the drought are burned before being crushed into ash for their calcium.

Climate change is compounding much of sub-Saharan Africa’s longstanding problem of poor soil fertility, said Wonder Ngezimana, an associate professor of crop science at Zimbabwe’s Marondera University of Agricultural Sciences and Technology.

“The combination is forcing people to re-look at how things were done in the past like nutrient recycling, but also blending these with modern methods,” said Ngezimana, whose institution is researching the combination of traditional practices with new technologies.

Apart from being rich in nitrogen, organic fertilizers help increase the soil’s carbon and ability to retain moisture, Ngezimana said. “Even if a farmer puts synthetic fertilizer into the soil, they are likely to suffer the consequences of poor moisture as long as there is a drought,” he said.

Other moves to traditional practices are under way. Drought-resistant millets, sorghum and legumes, staples until the early 20th century when they were overtaken by exotic white corn, have been taking up more land space in recent years.

Leaves of drought-resistant plants that were once a regular dish before being cast off as weeds are returning to dinner tables. They even appear on elite supermarket shelves and are served at classy restaurants, as are millet and sorghum.

This could create markets for the crops even beyond drought years, Ngezimana said.

A greenhouse revolution in Somalia

In conflict-prone Somalia in East Africa, greenhouses are changing the way some people live, with shoppers filling up carts with locally produced vegetables and traditionally nomadic pastoralists under pressure to settle down and grow crops.

“They are organic, fresh and healthy,” shopper Sucdi Hassan said in the capital, Mogadishu. “Knowing that they come from our local farms makes us feel secure.”

Her new shopping experience is a sign of relative calm after three decades of conflict and the climate shocks of drought and flooding.

Urban customers are now assured of year-round supplies, with more than 250 greenhouses dotted across Mogadishu and its outskirts producing fruit and vegetables. It is a huge leap.

“In the past, even basic vegetables like cucumbers and tomatoes were imported, causing logistical problems and added expenses,” said Somalia’s minister of youth and sports, Mohamed Barre.

The greenhouses also create employment in a country where about 75% of the population is people under 30 years old, many of them jobless.

About 15 kilometers from the capital, Mohamed Mahdi, an agriculture graduate, inspected produce in a greenhouse where he works.

“Given the high unemployment rate, we are grateful for the chance to work in our chosen field of expertise,” the 25-year-old said.

Meanwhile, some pastoralist herders are being forced to change their traditional ways after watching livestock die by the thousands.

“Transitioning to greenhouse farming provides pastoralists with a more resilient and sustainable livelihood option,” said Mohamed Okash, director of the Institute of Climate and Environment at SIMAD University in Mogadishu.

He called for larger investments in smart farming to combat food insecurity.

A more resilient bean in Kenya

In Kenya, a new climate-smart bean variety is bringing hope to farmers in a region that had recorded reduced rainfall in six consecutive rainy seasons.

The variety, called “Nyota” or “star” in Swahili, is the result of a collaboration between scientists from the Kenya Agricultural and Livestock Research Organization, the Alliance of Bioversity International and research organization International Center for Tropical Agriculture.

The new bean variety is tailored for Kenya’s diverse climatic conditions. One focus is to make sure drought doesn’t kill them off before they have time to flourish.

The bean variety flowers and matures so quickly that it is ready for harvesting by the time rains disappear, said David Karanja, a bean breeder and national coordinator for grains and legumes at KALRO.

Hopes are that these varieties could bolster national bean production. The annual production of 600,000 metric tons falls short of meeting annual demand of 755,000 metric tons, Karanja said.

Farmer Benson Gitonga said his yield and profits are increasing because of the new bean variety. He harvests between nine and 12 bags from an acre of land, up from the previous five to seven bags.

One side benefit of the variety is a breath of fresh air.

“Customers particularly appreciate its qualities, as it boasts low flatulence levels, making it an appealing choice,” Gitonga said.

LAGOS, Nigeria — When a small number of cases of locally transmitted malaria were found in the United States last year, it was a reminder that climate change is reviving or migrating the threat of some diseases. But across the African continent malaria has never left, killing or sickening millions of people.

Take Funmilayo Kotun, a 66-year-old resident of Makoko, an informal neighborhood in Nigeria’s Lagos city. Its ponds of dirty water provide favorable breeding conditions for malaria-spreading mosquitoes. Kotun can’t afford insecticide-treated bed nets that cost between $7 and $21 each, much less antimalarial medications or treatment.

For World Malaria Day on Thursday, here is what you need to know about the situation in Africa:

Malaria is still widespread

The malaria parasite mostly spreads to people via infected mosquitoes and can cause symptoms including fever, headaches and chills. It mostly affects children under 5 and pregnant women.

Vaccine efforts are still in early stages: Cameroon this year became the first country to routinely give children a new malaria vaccine, which is only about 30% effective and doesn’t stop transmission. A second vaccine was recently approved. On Thursday, WHO announced that three African countries — Benin, Liberia and Sierra Leone — were rolling out vaccine programs for millions of children.

Cases of resistance to antimalarial drugs and insecticides are increasing, while funding by governments and donors for innovation is slowing.

Living conditions play a role, with crowded neighborhoods, stagnant water, poor sanitation and lack of access to treatment and prevention materials all issues in many areas. And an invasive species of mosquito previously seen mostly in India and the Persian Gulf is a new concern.

A growing problem

Globally, malaria cases are on the rise. Infections increased from 233 million in 2019 to 249 million in 85 countries in 2022. Malaria deaths rose from 576,000 in 2019 to 608,000 in 2022, according to the World Health Organization.

Of the 12 countries that carry about 70% of the global burden of malaria, 11 are in Africa and the other is India. Children under 5 constituted 80% of the 580,000 malaria deaths recorded in Africa in 2022.

COVID-19 hurt progress

The fight against malaria saw some progress in areas such as rapid diagnostic tests, vaccines and new bed nets meant to counter insecticide resistance, but the COVID-19 pandemic and a shift in focus and funding set back efforts.

A study published in Tropical Medicine and Infectious Disease last year said COVID-19-induced lockdowns led to disruptions at 30% of rural community health service points across Africa. Malaria cases started spiking again, breaking a downward trend between 2000 and 2019.

That downward trend could soon return, according to the WHO.

A warming world and new frontiers

Africa is “at the sharp end of climate change,” and the increasing frequency of extreme weather events causes havoc in efforts to combat malaria in low- and middle-income regions, Peter Sands, the executive director of the Global Fund to Fight AIDS, Tuberculosis and Malaria, warned in December.

In 2023, the WHO’s World Malaria Report included a chapter on the link between malaria and climate change for the first time, highlighting its significance as a potential risk multiplier. Scientists worry that people living in areas once inhospitable to mosquitoes, including the slopes of Mount Kilimanjaro and the mountains of eastern Ethiopia, could be exposed.

In Zimbabwe, which has recorded some of its hottest days in decades, malaria transmission periods have extended in some districts, “and this shift has been attributed to climate change,” said Dr. Precious Andifasi, a WHO technical officer for malaria in Zimbabwe.

SYDNEY — The Asian Development Bank holds its annual meeting in Tbilisi, Georgia, next week, with discussions on climate change and the world’s aging population high on the agenda.

The four-day summit, starting Thursday, marks the first time that the ADB’s 68 members have gathered for a meeting in Georgia, which joined the multilateral development bank in 2007.

“Georgia sits at the crossroads of Europe and Asia,” said Shalini Mittal, a principal economist for Asia at the Economist Intelligence Unit.

“This meeting signifies ADB’s agenda of bridges to the future where technology and expertise from the West can be used to enhance structural reforms in Asia,” Mittal told VOA.

Alongside numerous panel discussions and a keynote speech from ADB President Masatsugu Asakawa, finance ministers from Association of Southeast Asian Nations member countries Japan, China and South Korea will also meet on the sidelines.

“Given the geopolitical uncertainty with the Ukraine-Russia war and tensions in Asia with China’s problematic relations with its neighbors, I think the meeting is taking place at a crucial time,” said Jason Chung, a senior adviser with the Project on Prosperity and Development at Washington’s Center for Strategic and International Studies.

“It provides an additional path to have meaningful discussions on global economic issues,” Chung told VOA.

Climate change stressed

The issue of climate change is set to headline proceedings at the conference, with the ADB now marketing itself as the climate bank for the Asia-Pacific region.

The bank pledged a record $9.8 billion of climate finance in 2023, supporting developing countries to cut greenhouse emissions and adapt to extreme conditions as global warming continues.

“Storm surges, sea level rise, heat waves, droughts, and floods — all our countries suffer from all of the imaginable impacts of climate change,” said Warren Evans, who, as senior special adviser on climate change in the ADB president’s office, acts as the institution’s climate envoy.

The bank says that the Asia-Pacific region was hit by over 200 disasters last year alone, with many of them weather related, a problem that shows no sign of letting up.

“Right now, there’s a heatwave in Bangladesh that is causing severe impacts. Schools are closed, they’re seeing a drop in agricultural productivity, hospitals are getting overloaded with people with heatstroke,” Evans told VOA.

“Mortality rates are going up and, of course, women and children are the most vulnerable to those impacts,” he said.

While much of the Asia-Pacific region is extremely vulnerable to climate change, it is also a huge driver of the phenomenon.

The region contributes more than half of global carbon dioxide emissions, with a heavy reliance on coal as a source of energy, according to the ADB.

To try to reach net zero targets, many Asia-Pacific nations require huge investment to convert to clean energy alternatives.

One way that the ADB is tackling this issue is through a program targeting coal-burning power plants, a major contributor to emissions.

“With private sector partners and sovereign funding, we’re refinancing coal-fired power plants in order to be able to close them down early,” Evans said. The ADB’s “energy transition mechanism” uses private and public capital to refinance investments in coal-fired power, allowing power purchase agreements to be shortened and plants to be closed as much as a decade earlier than planned. The financing is also used to fund clean energy projects to generate the power that would have come from the coal plant.

The project looks to replace these plants with clean energy alternatives, ensuring that power is generated more sustainably.

A coal-burning power plant in Indonesia’s West Java is set to become the first to be retired early under the initiative.

“The communities that are impacted will have support, allowing people to find new jobs or to get social welfare,” Evans said.

 

Aging population in Asia

During the Tbilisi summit, the ADB will also launch a major report on aging population, which also affects member countries’ economies.

According to the bank, 1 in 4 people in the Asia-Pacific region will be over 60 by 2050, close to 1.3 billion people.

“The speed of aging is very quick in Asia, because of the rapid progress in the social development that has taken place in the region,” said Aiko Kikkawa, a senior economist for the ADB’s Aging Well in Asia report.

Researchers have investigated the implications of this demographic transition, with Kikkawa finding that the Asia-Pacific region is currently “unprepared” for aging populations.

“Large numbers of older people do report a substantial disease burden, lack of access to decent jobs or essential services, such as health and long-term care, and even lack of access to pension coverage,” Kikkawa told VOA.

The ADB has pledged to help to improve the lives of older people across the Asia-Pacific region, by supporting the rollout of universal health coverage and providing infrastructure for ‘age-friendly cities’ that are more accessible for older people.

Poverty to be addressed

While much of the focus in Tbilisi will be on climate change and aging populations, the ADB’s core edict remains to eradicate extreme poverty in its many developing country members.

That task has become even more challenging in an environment of high inflation and growing government debt.

However, Chung, the former U.S. director of the ADB, told VOA he believes that this goal should be at the center of discussions in the Georgian capital.

“The ADB should focus on its core mission of alleviating poverty and creating paths for economic growth in the developing member countries.

“While climate risk is important, I think given the state of uncertainty, it is important to provide support to create economic conditions for growth,” he told VOA.

washington — About one-quarter of U.S. adults age 50 and older who are not yet retired say they expect to never retire, and 70% are concerned about prices rising faster than their income, an AARP survey finds.

About 1 in 4 have no retirement savings, according to research released Wednesday by the organization that shows how a graying America is worrying more and more about how to make ends meet even as economists and policymakers say the U.S. economy has all but achieved a soft landing after two years of record inflation.

Everyday expenses and housing costs, including rent and mortgage payments, are the biggest reasons why people are unable to save for retirement.

The data will matter this election year as Democratic President Joe Biden and Republican rival Donald Trump are trying to win support from older Americans, who traditionally turn out in high numbers, with their policy proposals.

Everyday expenses hamper saving

The AARP’s study, based on interviews completed with more than 8,000 people in coordination with the NORC Center for Public Affairs Research, finds that one-third of older adults with credit card debt carry a balance of more than $10,000 and 12% have a balance of $20,000 or more. Additionally, 37% are worried about meeting basic living costs such as food and housing.

“Far too many people lack access to retirement savings options and this, coupled with higher prices, is making it increasingly hard for people to choose when to retire,” said Indira Venkateswaran, AARP’s senior vice president of research. “Everyday expenses continue to be the top barrier to saving more for retirement, and some older Americans say that they never expect to retire.”

The share of people 50 and older who say they do not expect to retire has remained steady. It was 23% in January 2022 and 24% that July, according to the study, which is conducted twice a year.

“We are seeing an expansion of older workers staying in the workforce,” said David John, senior strategic policy advisor at the AARP Public Policy Institute. He said this is in part because older workers “don’t have sufficient retirement savings. It’s a problem and its likely to continue as we go forward.”

In the AARP survey, 33% of respondents 50 and older believe their finances will be better in a year.

Based on the 2022 congressional elections, census data released Tuesday shows that voters 65 and older made up 30.4% of all voters, while Gen Z and millennials accounted for 11.7%.

Biden has tried to court older voters by regularly promoting a $35 price cap on insulin for people on Medicare. He trumpets Medicare’s powers to negotiate directly with drugmakers on the cost of prescription medications.

Trump, in an interview with CNBC in March, indicated he would be open to cuts to Social Security and Medicare. The former president said “there is a lot you can do in terms of entitlements, in terms of cutting.”

Karoline Leavitt, press secretary for Trump’s campaign, said in a statement to The Associated Press on Tuesday that Trump “will continue to strongly protect Social Security and Medicare in his second term.”

Candidates court senior voters

A looming issue that will affect Americans’ ability to retire is the financial health of Social Security and Medicare.

The latest annual report from the program’s trustees says the financial safety nets for millions of older Americans will run short of money to pay full benefits within the next decade.

Medicare, the government-sponsored health insurance that covers 65 million older and disabled people, will be unable to pay full benefits for inpatient hospital visits and nursing home stays by 2031, the report forecast. And just two years later, Social Security will not have enough cash on hand to pay out full benefits to its 66 million retirees.

An AP-NORC poll from March 2023 found that most U.S. adults are opposed to proposals that would cut into Medicare or Social Security benefits, and a majority support raising taxes on the nation’s highest earners to keep Medicare running as is.

sydney — Analysis of more than 25,000 images from divers, tourism operators and recreational boats on Australia’s annual Great Reef Census is getting under way. Now in its fourth year, one of the world’s fastest-growing conservation projects is helping to gauge the health and degradation of the world’s largest coral system, which is suffering from another mass bleaching event.

The Great Reef Census collects a trove of images of what is arguably Australia’s greatest natural treasure.

Each picture can contain vital information about the health of the Great Barrier Reef. Together, the images create a vital evaluation of the state of the ecosystem.

The barrier reef stretches for 2,300 kilometers down Australia’s northeastern coast. It is under increasing threat from global warming, pollution and overfishing, as well as coral-eating crown of thorns starfish.

The surveillance project is urging so-called citizen scientists around the world to help in the analysis of the images. The survey also uses artificial intelligence to scan much of the data.

The public is being asked to analyze the images to see which reefs fared better than others and potentially identify so-called new “key source reefs,” which are those reefs that appear to have escaped the worst of the degradation.

Anyone can help in the effort, said Nicole Senn, impact and engagement lead at Citizens of the Reef, which coordinates the survey.

“Citizen scientists using our A.I assisted platform can actually provide data that is highly comparable in accuracy to a reef expert, and it takes as little as one minute to analyze an image, and the data you are generating helps to prioritize conservation efforts on the reef and identify key source reefs,” she said. “These are healthy reefs that are positioned in a way that they can help nearby reefs recover and this is just one of the many ways your analysis of these images can help.”

The Great Barrier Reef is suffering from another widespread bleaching event.

Scientists say that corals bleach, or turn white, when they are stressed by changes in water temperature, light, or nutrients. In response, the coral expels the symbiotic algae living in their tissues that give them their color and energy, exposing their white skeleton.

Not all bleaching incidents are due to warm water, but experts say the mass bleaching reported on the Great Barrier Reef is caused by a marine heatwave.

Experts say reefs around the world last year and early this year have been affected by high ocean surface temperatures.

Chris Lawson, a data scientist with the Great Reef Census’ Science Committee, told VOA that the situation appears to be dire.

“The latest mass bleaching event has been designated as the fourth global mass bleaching event,” he said. “So, it is not just in Australia, it has been observed globally and by all accounts is the worst one on record in terms of its extent and its severity of bleaching.”

Experts say reefs’ extreme susceptibility to warming sea temperatures makes them one of the world’s ecosystems that is most vulnerable to climate change.
