BOULDER, Colo. — Space weather forecasters have issued a geomagnetic storm watch through Monday, saying an outburst of plasma from a solar flare could interfere with radio transmissions on Earth. It could also make for great aurora viewing.

There’s no reason for the public to be concerned, according to the alert issued Saturday by NOAA’s Space Weather Prediction Center in Boulder, Colorado.

The storm could interrupt high-frequency radio transmissions, such as by aircraft trying to communicate with distant traffic control towers. Most commercial aircraft can use satellite transmission as backup, said Jonathan Lash, a forecaster at the center.

Satellite operators might have trouble tracking their spacecraft, and power grids could also see some “induced current” in their lines, though nothing they can’t handle, he said.

“For the general public, if you have clear skies at night and you are at higher latitudes, this would be a great opportunity to see the skies light up,” Lash said.

Every 11 years, the sun’s magnetic field flips, meaning its north and south poles switch positions. Solar activity changes during that cycle, and it’s now near its most active, called the solar maximum.

During such times, geomagnetic storms of the type that arrived Sunday can hit Earth a few times a year, Lash said. During solar minimum, a few years may pass between storms.

In December, the biggest solar flare in years disrupted radio communications.

Geneva — In marking World Tuberculosis Day, the World Health Organization is calling for action to rid the world of this ancient scourge, which has sickened and killed millions of people throughout the ages.

This year’s theme, “Yes! We can end TB,” is intended to send a message of hope that ending the epidemic, which WHO says each year causes the deaths of some 1.3 million people, is possible.

While the disease is curable and preventable, heads of state at the 2023 U.N. high-level meeting on TB estimated that $13 billion was needed every year for prevention, diagnosis, treatment, and care to end the epidemic by 2030.

The heads of state, who pledged to accelerate progress to end TB and to turn these commitments “into tangible actions,” approved a series of global targets for moving this process forward.

“These include reaching 90% of people in need with TB prevention and care services, using WHO-recommended rapid tests and the first method of diagnosing TB, and providing a health and social benefit package to all people with tuberculosis,” said Dr. Tereza Kasaeva, director of WHO’s Global Tuberculosis Program.

“This is a watershed for the global fight to end tuberculosis. The next five years will be critical for ensuring that the political momentum we have now is translated into concrete action towards reaching global TB targets.”

Tuberculosis is the world’s second leading infectious killer after COVID-19, above HIV and AIDS. WHO reports 1.3 million people died from TB in 2022 and an estimated 10.6 million fell ill with the disease.

This is the highest number of new cases since the agency began monitoring the disease in 1995. WHO says the sharp rise may be linked to “delays in treatment caused by the COVID-19 pandemic.”

TB, an airborne disease, spreads when infected people cough, sneeze, or spit. It is present in all countries and age groups.

“Preventing TB infection and stopping progression from infection to disease are critical for reducing the incidence to the levels envisioned by the anti-TB strategy,” said Saskia Den Boon, technical officer, WHO Global TB Program.

“One of the key health care interventions to achieve this reduction is TB preventive treatment, which WHO recommends for people living with HIV, household contacts of people with TB and other risk groups.

“Strategies to provide preventive treatment are often linked to screening, to find and treat people earlier in the course of their disease and thus help to prevent transmission and improve outcomes,” she said.

In recent years, new tools developed and recommended by WHO are making TB screening more feasible. These include shorter preventive treatments of one or three months and a new antigen-based skin test for TB infection.

“For screening, WHO recommends the use of artificial intelligence or AI for the computer aided protection of tuberculosis abnormalities on chest x-ray among other tests,” said Den Boon.

WHO has released a modeling study that examines the costs and benefits of screening and preventive treatment in four countries — Brazil, Georgia, Kenya, and South Africa.

“The investment case studies showed that in all four countries, many TB episodes can be prevented, and lives saved by investing in TB screening,” Den Boon said.

“The modeling showed that relatively modest investments can achieve significant health and economic benefits in all four countries… From a societal perspective, the intervention package was cost-saving in all four countries. The return on investment varied between countries and was up to $39 gained for every dollar invested,” she said.

WHO scientists agree that early diagnosis is crucial to tackling, curing, and preventing the spread of tuberculosis. By the same token, they agree on the importance of developing new vaccines for prevention and eventual eradication.

Currently, only the BCG TB vaccine for children is available and it is 100 years old.

“Indeed, it is absolutely unacceptable that in the 21st century with a lot of innovations, we still do not have a new effective, TB vaccine,” said Kasaeva.

She said WHO’s director general, Tedros Adhanom Gebreyesus, launched a TB Vaccine Accelerator Council last year to bring attention to this problem and attract investments for research and development.

She said the U.N. high-level meeting is backing WHO’s initiative, adding, “This will make it possible to have new TB vaccines within the next five years.”

“We have more than 16 candidates in the pipeline, some of them in the later stages,” she said, “but we need more attention, more prioritization, more investments.”

ALONG RIVER RWIZI, Uganda — Along a stretch of bush by a muddy river, laborers dug and slashed in search of bamboo plants buried under dense grass. Here and there a few plants had sprouted tall, but most of the bamboo seedlings planted more than a year ago never grew.

Now, environment protection officers seeking to restore a 3-kilometer stretch of the river’s degraded banks were aiming to plant new bamboo seedlings, clear room for last year’s survivors to grow and look after them better than they did the first time.

A successful bamboo forest by the river Rwizi — the most important in a large part of western Uganda that includes the major city of Mbarara — would create a buffer zone against sand miners, subsistence farmers and others whose activities have long threatened the river. The National Environment Management Authority estimates that the Rwizi has lost 60% of its water catchment area over the decades, and in some areas this winding river runs as narrow as a stream.

“Once bamboo is established, it is almost like a net,” said Jeconious Musingwire, an environment officer who was the project’s technical adviser. “The roots trap everything, including the surface runoff, and stabilize the weaknesses of the banks.”

Uganda is seeing growing interest in bamboo, a perennial plant cultivated in many parts of the world. It can be burned for fuel in rural communities, taking pressure off dwindling forest reserves of eucalyptus and other natural resources. It’s a hardy plant that can grow almost anywhere. And businesses can turn it into products ranging from furniture to toothpicks.

Some of the bamboo species grown in Uganda are imported from Asia, but many — like one whose shoots are smoked and then boiled to make a popular traditional meal in eastern Uganda — grow wild.

The Ugandan government has set a 10-year policy that calls for planting 300,000 hectares of bamboo, most of it on private land, by 2029 as part of wider reforestation efforts.

That’s an ambitious target. The Uganda Bamboo Association, the largest such group with 340 members, has planted only 500 hectares. Even with growing interest in bamboo farming, authorities will have to encourage more farmers in rural parts of Uganda to plant vast tracts of land with bamboo.

But signs are promising.

Not far from the scene where laborers were tending bamboo plants sits a large commercial farm that includes seven acres of bamboo. The plants at Kitara Farm were well-tended, and a stockpile of 10,000 bamboo poles sat waiting to be sold.

Caretaker Joseph Katumba said the property has become something of a demonstration farm for people who want to learn more about bamboo. He recalled that when they first began planting bamboo in 2017, some people asked why they were “wasting land” by planting bamboo when it grows wild in the bush.

Katumba said that’s changed, with skeptics now interested in planting bamboo “because they have studied it and they love it.” Unlike eucalyptus — a tall flowering plant widely planted here for its timber — “there is no bamboo season. The more you look after it well, weeding around it, the more and more years you will earn from bamboo.”

Bamboo grows faster than eucalyptus and regenerates like a weed. It also can thrive in poor soil. Kitara Farm stopped planting new eucalyptus lots while its bamboo acreage continues to expand, he said.

“We have so many eucalyptus forests. But we realized that once you cut the eucalyptus trees, eventually they get finished, and once they are finished there is no more money,” he said. “But with bamboo, we investigated and found out that when you plant it … the grandkids and their grandkids and their grandkids will earn from bamboo.”

A single bamboo pole brings a little less than a dollar, so farmers need to grow a lot to earn enough. Bamboo promoters are urging them to see a bamboo plantation as the same kind of cash crop as coffee or tea estates. Banks are offering bamboo “plantation capital” to clients, loans that promise ownership of substantial acres of bamboo.

“Each person should actually plant bamboo, and a lot of it,” said Taga Nuwagaba, a bamboo farmer and businessman who owns a bamboo furniture factory near the Ugandan capital of Kampala. He touts the plant as a a renewable resource that sequesters carbon, too.

“You cut one, five will grow,” he said.

Bamboo plants are normally ready for harvesting in three to five years, and a well-maintained plantation can be useful for at least 50 years, said Jacob Ogola, an agronomist who is working as a consultant at Kitara Farm. He said bamboo is easy to manage, and typically doesn’t need spraying for pests.

Bamboo seedlings are now more widely available via private nursery beds.

Steve Tusiime, a self-described bamboo collector, owns one such nursery in Mbarara. Tusiime said he’s been fascinated by the plant since seeing one as a boy. Before he got into growing, he recalls traveling to a farm in central Uganda to “hug” bamboo plants, and in 2018 spending his own money to attend a bamboo convention in China, where he got his first bamboo seeds.

Standing on another stretch of land by the river Rwizi where he and his partners have created a bamboo park in a recreation resort still to be commissioned, he waxed lyrical about how bamboo “energizes” him.

“Each bamboo you see here has a story. It has where it comes from and it has different use and it has a different name,” he said. “When you come here the story is bamboo. You learn about different species, different uses. You see different features of bamboo.”

Still, Uganda’s bamboo plantations aren’t growing fast enough to build an industry around the plant. Tusiime’s nursery has sold fewer than 10,000 seedlings in the past two years, confounding his own assessment of bamboo as an important cash crop which also happens to benefit the environment.

“Bamboo can be a future tree for Uganda or for even Africa. For example, you’ve heard people talking about charcoal and firewood and this and that. Bamboo is a better solution,” he said. “You can produce the briquette, you can use it directly as firewood. Bamboo is going to be a game changer in Africa. You can eat bamboo, you can use it to build, you can create an industry for bamboo, you can feed it to your animals, and it can take care of your land.”

BENGALURU, India — Abinaya Tamilarasu said her four cows are part of the family. She has a degree in commerce from a local college, but prefers being home milking cows and tending to her family’s land.

“Our family cannot let farming go, it’s a way of life for us,” said the 28-year-old, who lives on her family farm in India’s southern Tamil Nadu state. Even when she could be making more money elsewhere, she said she’s “still happy we have our cows.”

India is the world’s largest milk producer, and is home to 80 million dairy farmers who made 231 million tons of milk last year. Many farmers, like Tamilarasu, only have a few cows, but the industry as a whole has 303 million bovine cattle like cows and buffalo, making it the largest contributor to planet-warming methane emissions in the country. The federal government has made some positive steps to reduce methane, but wants to focus emissions cuts elsewhere, like by moving to renewable energy, saying most methane emissions are a fact of life. But experts say the industry can and should make more reductions that can quickly limit warming.

India is the third-largest emitter of methane in the world, according to figures published earlier this month by the International Energy Agency, and livestock are responsible for about 48% of all methane emissions in India, the vast majority from cattle. Methane is a potent planet-warming gas that can trap more than 80 times more heat in the atmosphere in the short term than carbon dioxide.

The Indian government has not joined any global pledges to cut methane emissions, which many see as low-hanging fruit for climate solutions, as methane emissions only last in the atmosphere for about a dozen years, compared to CO2 that can linger for a couple of hundred years.

But there’s some work on methane reduction in agriculture on the national level: The government’s National Dairy Development Board, which works with more than 17 million farmers across the country, is looking into genetic improvement programs to provide more nutritious feed to livestock which would make cows more productive, meaning each farmer would need fewer cows to produce the same amount of milk. Studies by the NDDB show that emissions are reduced by as much as 15% when a balanced diet is provided to the animals.

The board is also looking into reducing crop burning, a high-emitting practice that some farmers use to clear their lands, by feeding those crops to cows.

“Climate-smart dairying is the need of the hour,” said Meenesh Shah, the board’s chairman.

Vineet Kumar, from the New Delhi-based Centre for Science and Environment, agreed that good quality feed can help lower emissions. He also said encouraging more local breeds that emit less can help. “These solutions can be a win-win for everyone,” he said.

But Thanammal Ravichandran, a veterinarian based in the southern Indian city of Coimbatore, noted that there’s currently a shortage of feed in India, so farmers give their cattle whatever they can, which is mostly lower quality and higher emitting.

“Farmers are also not able to invest in better quality feed for their cattle,” she said. To get better, and more affordable feed, dairy farmers need more government support, she said.

Whatever measures are taken to reduce methane emissions, experts note that it should have minimal impact on farmers’ livelihoods, and should account for the ways people raise their livestock.

“Livestock have been closely integrated within the Indian farming system,” said Kumar, meaning any drastic changes to farming methods would have severe effects on farmers. He added that efforts to reduce emissions shouldn’t reduce the use of cow manure as fertilizer on India’s farms, as chemical fertilizers emit nitrous oxide, an even more potent greenhouse gas.

But looking at India’s methane emissions as a whole could provide some more obvious solutions to slashing the gas, said Bandish Patel, an energy analyst at the climate thinktank Ember. Focusing on the energy sector is an easy win for targeted reduction of methane emissions, he said.

“You look at agriculture, those emissions are very dispersed in nature, whereas, with oil, gas and coal mining, there are very pointed sources from which you can basically reduce methane going forward,” he said.

Shah from the NDDB added that India’s high agricultural emissions must be considered in the context of the country being home to the world’s largest cattle population, the largest producer of milk, and the largest rice exporter, as rice production also produces significant methane emissions.

“In this light, India’s agriculture sector emissions must be considered significantly low,” Shah said. Because of its large population, India’s per capita emissions are well below average.

For dairy farmers like Tamilarasu, better welfare for her cows and programs for farmers to have better practices are welcome, but she won’t be leaving her cows for the climate any time soon. She plans to continue dairy farming for the foreseeable future.

“The way we see it, our cows and us support each other. If we can make their lives better, they will make ours better too,” she said.

washington — At least 54 people have lost their lives to cholera in Somalia in recent months. Nine of those deaths occurred within the past week, marking the highest weekly death toll this year, humanitarian group Save the Children said.   

In an interview with VOA Somali, Mohamed Abdulkadir, acting operations director for Save the Children Somalia, said the statistic highlights how vulnerable children are to the deadly disease. 

“In collaboration with Somalia’s Ministry of Health and Human Services, Save the Children reveals that among 4,388 confirmed cases in 2024, 59% belong to children under the age of five,” Abdulkadir said. 

In the southern states of the country, Mogadishu, the country’s capital, has experienced a significant surge in reported cholera cases in the past two weeks. 

Abdulkadir said 586 new cases have been reported in 23 districts, with 331 of them affecting children under the age of five. 

The outbreak, which began in January of this year, is believed to be a direct consequence of severe flooding that occurred in October and November 2023.

“We believe that the recent devastating flooding in areas like Mogadishu, Beledweyne and Baidoa has contributed to the outbreak of the disease,” said Abdulkadir.   

He said Save the Children is urgently calling for action from local governments and health agencies to combat the rapid spread of cholera. 

“We call for an action from the Somali federal government and the local governments to fight against this highly contagious disease, which primarily spreads through contaminated water areas with inadequate sewage treatment, flooded regions,” he said.

People who lack safe drinking water are particularly susceptible to the cholera outbreak, especially in the wake of flooding, he added.

To prevent further transmission of the disease, he said Save the Children is implementing an emergency response strategy. The aid agency is establishing two cholera treatment centers, providing essential hygiene kits and water treatment supplies in Beledweyne. 

Abdulkadir emphasized the gravity of the situation, stating that Somalia is at the forefront of the climate crisis. 

He said the combination of relentless rainfall, floods, and a devastating drought has left children and families extremely vulnerable to illness. He stressed the urgent need for clean drinking water and sanitation facilities to prevent the cholera outbreak from spiraling out of control when the rainy season begins in a month. 

In 2023, Somalia recorded more than 18,300 cases of cholera, with 10,000 of those cases affecting children under the age of five. Both Save the Children and the Somali government attributed the devastating rise in numbers to the destructive El Nino flooding in November and December, which destroyed toilets and latrines. Consequently, many communities, particularly those recently displaced by flooding and conflict, resorted to open defecation.

DALLAS — It has been 15 years since the last fatal crash of a U.S. airliner, but you would never know that by reading about a torrent of flight problems in the last three months.

There was a time when things like cracked windshields and minor engine problems didn’t turn up very often in the news.

That changed in January, when a panel plugging the space reserved for an unused emergency door blew off an Alaska Airlines jetliner 16,000 feet above Oregon. Pilots landed the Boeing 737 Max safely, but in the United States, media coverage of the flight quickly overshadowed a deadly runway crash in Tokyo three days earlier.

And concern about air safety — especially with Boeing planes — has not let up.

Is flying getting more dangerous?

By the simplest measurement, the answer is no. The last deadly crash involving a U.S. airliner occurred in February 2009, an unprecedented streak of safety. There were 9.6 million flights last year.

The lack of fatal crashes does not fully capture the state of safety, however. In the past 15 months, a spate of close calls caught the attention of regulators and travelers.

Another measure is the number of times pilots broadcast an emergency call to air traffic controllers. Flightradar24, a popular tracking site, just compiled the numbers. The site’s data show such calls rising since mid-January but remaining below levels seen during much of 2023.

Emergency calls also are an imperfect gauge: the plane might not have been in immediate danger, and sometimes planes in trouble never alert controllers.

Safer than driving

The National Safety Council estimates that Americans have a 1-in-93 chance of dying in a motor-vehicle crash, while deaths on airplanes are too rare to calculate the odds. Figures from the U.S. Department of Transportation tell a similar story.

“This is the safest form of transportation ever created, whereas every day on the nation’s roads about a 737 full of people dies,” Richard Aboulafia, a longtime aerospace analyst and consultant, said. The safety council estimates that more than 44,000 people died in U.S. vehicle crashes in 2023.

But a shrinking safety margin

A panel of experts reported in November that a shortage of air traffic controllers, outdated plane-tracking technology and other problems presented a growing threat to safety in the sky.

“The current erosion in the margin of safety in the (national airspace system) caused by the confluence of these challenges is rendering the current level of safety unsustainable,” the group said in a 52-page report.

What is going on at Boeing?

Many but not all of the recent incidents have involved Boeing planes.

Boeing is a $78 billion company, a leading U.S. exporter and a century-old, iconic name in aircraft manufacturing. It is one-half of the duopoly, along with Europe’s Airbus, that dominates the production of large passenger jets.

The company’s reputation, however, was greatly damaged by the crashes of two 737 Max jets — one in Indonesia in 2018, the other in Ethiopia the following year — that killed 346 people. Boeing has lost nearly $24 billion in the last five years. It has struggled with manufacturing flaws that at times delayed deliveries of 737s and long-haul 787 Dreamliners.

Boeing finally was beginning to regain its stride until the Alaska Airlines Max blowout. Investigators have focused on bolts that help secure the door-plug panel, but which were missing after a repair job at the Boeing factory.

The FBI is notifying passengers about a criminal investigation. The Federal Aviation Administration is stepping up oversight of the company.

“What is going on with the production at Boeing? There have been issues in the past. They don’t seem to be getting resolved,” FAA Administrator Mike Whitaker said last month.

CEO David Calhoun says no matter what conclusions investigators reach about the Alaska Airlines blowout, “Boeing is accountable for what happened” on the Alaska plane. “We caused the problem and we understand that.”

Where do design and manufacturing fit in?

Problems attributed to an airplane manufacturer can differ greatly.

Some are design errors. On the original Boeing Max, the failure of a single sensor caused a flight-control system to point the nose of the plane down with great force — that happened before the deadly 2018 and 2019 Max crashes. It is a maxim in aviation that the failure of a single part should never be enough to bring down a plane.

In other cases, such as the door-plug panel that flew off the Alaska Airlines jet, it appears a mistake was made on the factory floor.

“Anything that results in death is worse, but design is a lot harder to deal with because you have to locate the problem and fix it,” said Aboulafia, the aerospace analyst. “In the manufacturing process, the fix is incredibly easy – don’t do” whatever caused the flaw in the first place.

Manufacturing quality appears to be an issue in other incidents too.

Earlier this month, the FAA proposed ordering airlines to inspect wiring bundles around the spoilers on Max jets. The order was prompted by a report that chafing of electrical wires due to faulty installation caused an airliner to roll 30 degrees in less than a second on a 2021 flight.

Even little things matter. After a LATAM Airlines Boeing 787 flying from Australia to New Zealand this month went into a nosedive — it recovered — Boeing reminded airlines to inspect switches to motors that move pilot seats. Published reports said a flight attendant accidentally hitting the switch likely caused the plunge.

Not everything is Boeing’s fault

Investigations into some incidents point to likely lapses in maintenance, and many close calls are due to errors by pilots or air traffic controllers.

This week, investigators disclosed that an American Airlines jet that overshot a runway in Texas had undergone a brake-replacement job four days earlier, and some hydraulic lines to the brakes were not properly reattached.

Earlier this month, a tire fell off a United Airlines Boeing 777 leaving San Francisco, and an American Airlines 777 made an emergency landing in Los Angeles with a flat tire.

A piece of the aluminum skin was discovered missing when a United Boeing 737 landed in Oregon last week. Unlike the brand-new Alaska jet that suffered the panel blowout, the United plane was 26 years old. Maintenance is up to the airline.

When a FedEx cargo plane landing last year in Austin, Texas, flew close over the top of a departing Southwest Airlines jet, it turned out that an air traffic controller had cleared both planes to use the same runway.

Separating serious from routine

Aviation-industry officials say the most concerning events involve issues with flight controls, engines and structural integrity.

Other things such as cracked windshields and planes clipping each other at the airport rarely pose a safety threat. Warnings lights might indicate a serious problem or a false alarm.

“We take every event seriously,” former NTSB member John Goglia said, citing such vigilance as a contributor to the current crash-free streak. “The challenge we have in aviation is trying to keep it there.”

PORTLAND, Maine — Avian influenza is killing tens of thousands of seals and sea lions in different corners of the world, disrupting ecosystems and flummoxing scientists who don’t see a clear way to slow the devastating virus.

The worldwide bird flu outbreak that began in 2020 has led to the deaths of millions of domesticated birds and spread to wildlife all over the globe. This virus isn’t thought to be a major threat to humans, but its spread in farming operations and wild ecosystems has caused widespread economic turmoil and environmental disruptions.

Seals and sea lions, in places as far apart as Maine and Chile, appear to be especially vulnerable to the disease, scientists said. The virus has been detected in seals on the east and west coasts of the U.S., leading to deaths of more than 300 seals in New England and a handful more in Puget Sound in Washington. The situation is even more dire in South America, where more than 20,000 sea lions have died in Chile and Peru and thousands of elephant seals have died in Argentina.

The virus can be controlled in domesticated animals, but it can spread unchecked in wildlife and marine mammals such as South America’s seals that lacked prior exposure to it have suffered devastating consequences, said Marcela Uhart, director of the Latin America program at the Karen C. Drayer Wildlife Health Center at the University of California, Davis.

“Once the virus is in wildlife, it spreads like wildfire, as long as there are susceptible animals and species,” Uhart said. “Movement of animals spreads the virus to new areas.”

Scientists are still researching how the seals have contracted bird flu, but it is most likely from contact with infected seabirds, Uhart said. High mortality has affected South American marine mammals consistently since the virus arrived late in 2022, and birds in Peru and Chile have died by the hundreds of thousands from the virus since then, she noted.

The virus is still spreading and was detected in mainland Antarctica for the first time in February.

The deaths of seals and sea lions disrupts ecosystems where the marine mammals serve as key predators near the top of the food chain. Seals help keep the ocean in balance by preventing overpopulation of the fish species they feed on.

Many species affected, such as South American sea lions and Southern elephant seals, have relatively stable populations, but scientists worry about the possibility of the virus jumping to more jeopardized animals. Scientists have said bird flu might have played a role in the deaths of hundreds of endangered Caspian seals in Russia last year.

“The loss of wildlife at the current scale presents an unprecedented risk of wildlife population collapse, creating an ecological crisis,” the World Organization for Animal Health, an intergovernmental organization, said in a statement.

In New England, scientists with the Cummings School of Veterinary Medicine at Tufts University found an outbreak of bird flu that killed more than 330 harbor and gray seals along the North Atlantic coast in 2022 turned out to be worse than initially thought. It’s possible the seals contracted the virus from gulls by coming into contact with sick gulls’ excrement or by preying on an infected bird, the scientists reported.

The U.S. government determined the seal die-off was an “unusual mortality event” attributable to bird flu. The National Oceanic and Atmospheric Administration has declared the event is over, but concerns remain about a possible repeat.

“Marine mammals are still pretty unique in the scale of the outbreaks that are occurring,” said Wendy Puryear, an author of the Tufts study. “One of the connections is there is a lot of virus that circulates in coastal birds. A lot of opportunities for those wild birds to host the virus and pass it on to marine mammals.”

Some scientists and environmental advocates say there could be a link between the outbreaks and climate change and warming oceans. Warmer sea temperatures off northern Chile decrease the population of forage fish, and that makes sea lions weaker and more susceptible to disease, said Liesbeth van der Meer, director of the environmental group Oceana in Chile.

Scientists and environmentalists are hopeful vaccinating poultry will help lessen the spread of the disease, van der Meer said, adding that it’s also important for people to avoid potentially infected animals in the wild.

“Authorities have carried out campaigns about the disease, strongly recommending to stay away from seabirds or marine mammals with symptoms or found dead in the coastal areas,” van der Meer said.

Even seals in aquariums are not considered completely safe from bird flu. The New England Aquarium, where outdoor harbor seal exhibits delight thousands of visitors every year, has taken strict sanitation precautions to prevent transmission of the virus to its animals, said Melissa Joblon, the Boston aquarium’s director of animal health.

Staff aren’t allowed to bring backyard poultry products to the aquarium, and an awning protects the seal exhibit from birds that could carry the virus, she said.

“We do know that it’s a risk for the animals that reside here,” said Joblon, adding that none of the aquarium’s seals have been infected.

The deaths of marine mammals are even more concerning because of mutations of the avian virus, according to a paper in the journal Nature Communications last fall. The mutations “warrant further examination and highlight an urgent need for active local surveillance to manage outbreaks and limit spillover into other species, including humans,” the study stated. 

Another study, published in the journal Emerging Infectious Diseases in February, found the bird flu virus has adapted to spread between birds and mammals. Researchers found nearly identical samples of the virus in dead sea lions, a dead seal and a dead seabird. They said the finding is significant because it confirms a multispecies outbreak that can affect marine mammals and birds. 

More seal deaths could disrupt critical ecosystems around the world, said Lynda Doughty, executive director of Marine Mammals of Maine, a marine mammal rescue organization that responded to seals with bird flu during the New England outbreak. 

“You need this happy ecosystem. If we’re taking out some important species, what is the trickle-down effect of that? That’s the million-dollar question,” Doughty said.

geneva — The World Health Organization warns that hunger, poverty, malnutrition, and disease have reached alarming levels in the Democratic Republic of Congo, especially in the east, where a resurgence of fighting between armed groups and government forces has uprooted millions of people from their homes. 

“DRC is the second-largest displacement crisis globally after Sudan, with more people forced to flee the violence since the start of the year,” said Dr. Boureima Hama Sambo, WHO representative to the DRC. 

Speaking from the capital, Kinshasa, Sambo told journalists in Geneva Friday that a combination of violence, climate shocks, and epidemics has worsened the humanitarian and overall health situation for millions of people who are struggling to find enough food to eat, a safe place to stay, and help to ward off disease outbreaks.   

“Hospitals are overwhelmed with injured people,” he said. “Close to 10 million people are on the move. Poverty and hunger affect a quarter of the population or 25.4 million people. The spread of cholera and other infectious diseases pose significant threats to the populations health.”   

United Nations relief agencies say more than two of every five children in the DRC — around 6 million children — suffer from chronic malnutrition, a condition that causes stunting, impairs cognitive development, and in cases of severe acute malnutrition, a risk of death. 

Sambo said that, “Combined to malnutrition, diseases are increasing the risk of mortality, especially in children, and putting even more pressure on the health system.  

“Women and girls are paying the high price of armed conflict and displacement,” he said, noting that “30,000 cases of gender-based violence were reported in the DRC in 2023. These numbers are among the highest in the world.” 

Flooding heightens risk 

Besides conflict-related challenges, the Office for the Coordination of Humanitarian Affairs, OCHA, says severe flooding has wreaked havoc in 18 of the DRCs 26 provinces, leaving more than 2 million people, nearly 60%  of them children, in need of assistance.   

The WHO says floods are worsening the risk of diarrheal and water-borne diseases. That, as well as the outbreak of other diseases, including cholera, measles, polio, yellow fever, anthrax, and plague, has brought an already fragile health system to its knees.   

“DRC is facing its worst cholera outbreak since 2017 with 50,000 suspected cases and 470 deaths recorded in 2023,” said Sambo, adding that the risk is particularly high in sites for internally displaced people where “living conditions are dire.” 

He said the country is also battling its largest measles epidemic since 2019, with close to 28,000 cases with 750 deaths so far this year   

“The combination of measles and malnutrition has a severe health impact on children under five years of age and the lack of access to vaccines and vaccination services further exacerbate the situation,” he said. 

Threat of mpox grows

In addition to those problems, the WHO warns mpox — previously known as monkeypox — has been on the rise across the country over the last year, with nearly 4,000 suspected cases and 271 deaths reported.  

That represents a higher case fatality than was seen during a year-long, WHO-declared international public health emergency for the disease that began in May 2022. More than two thirds of the current cases, it says, are reported in children.   

Mpox, a zoonotic disease first detected in a 9-month-old in 1970 in the DRC, when the country was known as Zaire.  Dr. Rosamund Lewis, WHO technical lead for mpox, says children continue to be most at risk of getting infected with and dying from the disease.  

“The number of cases has been gradually increasing over time. What we saw in 2023 was more than the doubling of the number of cases compared to 2022 … There is a clear concern about the continuing spread of the disease, not only by zoonotic transmission but through person-to-person sexual contact,” she said. 

“What is also new about transmission in the DRC is that sexual transmission reported for Clade 1, a variant of mpox had not been reported prior to 2023. Now what we are seeing is newly reported sexual transmission in a different part of the country, which is not endemic for mpox.”   

Lewis said the disease is spreading in areas “where there is a lot of commercial back and forth, including cross-borders and a vibrant commercial sex trade.” 

The WHO reports mpox has expanded to previously unaffected provinces, such that almost all provinces. including Kinshasa, now are reporting cases. It warns that “represents a threat to neighboring countries and beyond.”   

WHO representative Sambo observed that humanitarian needs in the country are soaring, with close to 20 million people requiring health assistance this year. Despite all the compounding challenges, he said the WHO has been scaling up its health response since last year. 

For example, he said the WHO vaccinated almost 5 million people against cholera in November, most in the eastern provinces, and vaccinated millions of people against a deadly measles outbreak last year.  Next week, he said the WHO plans to start a polio vaccination campaign in all 26 provinces. 

However, he said that continuing such lifesaving programs will be difficult to do if the health response remains severely underfunded, noting that less than 14 percent of the WHOs $624 million appeal for this year has been received.   

He urges the world not “to turn a blind eye to a situation that could have severe knock-on effects for security and health in the region.”

Nairobi, Kenya — With a week until Easter, chocolate lovers should brace themselves for higher prices when they purchase their favorite seasonal treats.

A nonprofit environmental group says cocoa costs three times more than it did a year ago because of climate change and the El Nino weather effect. Prices reached $8,000 per ton this week, compared with $2,500 last year at this time.

Amber Sawyer, a climate and energy analyst at the Energy and Climate Intelligence Unit, or ECIU, a U.K.-based nonprofit group, said the volatile weather patterns in the top cocoa-producing countries of Ghana and Ivory Coast have affected international commodity prices.

“Chocolate producers are trying to buy up cocoa, but there’s a reduced supply of it,” she said. “So obviously, because of the reduced supply, the demand has gone up, and the prices have therefore gone up for confectionery companies who make chocolate. These costs are now being fed through to consumers.”

Ghana and Ivory Coast, which produce nearly 60% of global cocoa, experienced heavy rains in December. Flooding caused crop damage and led to cocoa plants rotting with black pod disease.

Extreme heat has hurt, too.

“That’s affecting not only the crop, because it’s difficult to grow cocoa in these conditions, but also the farmers themselves,” Sawyer said.

“Farmers have gone from having too much rain to not enough rain, which means that they’re behind on production and unable to sell on the international markets,” she said.

Ghana has reduced its cocoa production estimate this year from 850,000 to 650,000 tons due to adverse weather conditions and smuggling.

United Nations Food and Agriculture Organization data show cocoa is grown in countries that are most vulnerable and less prepared to deal with climate change.

A U.K.-based World Weather Attribution website analysis released Thursday showed that West Africa experienced an intense heatwave in February, with temperatures above 40 degrees Celsius (104 Fahrenheit).

Izidine Pinto, a researcher with the Royal Netherlands Metrological Institute connected with the website, said the heatwaves and heavy rainfall affect people’s lives and jobs.

“Climate change is making rainfall heavier and heatwaves like these more intense,” he said. “These changes to extreme weather are making life more dangerous for people in West Africa. … This is damaging livelihoods … damaging crops and making food prices more expensive.”

Weather experts note that heatwaves used to occur once every 100 years before widespread fossil fuel burning, but in today’s climate, heatwaves happen once every 10 years.

African countries bear the brunt of climate change despite contributing the least to greenhouse gas emissions. The ECIU urges wealthier nations to offer financial and technical aid to assist farmers in managing the impact of severe weather and climate change.

washington — There definitely were no Muppets during the Permian Period, but there was a Kermit — or at least a forerunner of modern amphibians that has been named after the celebrity frog.

Scientists on Thursday described the fossilized skull of a creature called Kermitops gratus that lived in what is now Texas about 270 million years ago. It belongs to a lineage believed to have given rise to the three living branches of amphibians — frogs, salamanders and limbless caecilians.

While only the skull, measuring around 3 cm long, was discovered, the researchers think Kermitops had a stoutly built salamander-like body roughly 15-18 cm long, though salamanders would not evolve for another roughly 100 million years.

Amphibians are one of the four groups of living terrestrial vertebrates, along with reptiles, birds and mammals. The unique features of the Kermitops skull — a blend of archaic and more advanced features — are providing insight into amphibian evolution.

“Kermitops helps us understand the early history of amphibians by revealing there isn’t a clear trend of step by step becoming more like the modern amphibian,” said Calvin So, a George Washington University paleontology doctoral student and lead author of the study published in the Zoological Journal of the Linnean Society.

The fossil was collected in 1984 near Lake Kemp in Texas and kept in the expansive collection of the Smithsonian Institution’s National Museum of Natural History in Washington but was not thoroughly studied until recently.

Kermitops had a rounded snout, not unlike frogs and salamanders. Preserved in its eye sockets were palpebral bones, or eyelid bones, a feature absent in today’s amphibians. Its skull is constructed of roof-like bones, in contrast to the thin and strut-like bones of modern amphibians.

“The length of the skull in front of the eyes is longer than the length of the skull behind the eyes, which differs from the other fossil amphibians living at the same time. We think this might have allowed Kermitops to snap its jaws closed faster, enabling capture of fast insect prey,” So said.

The fossil record of early amphibians and their forerunners is spotty, making it difficult to figure out the origins of modern amphibians.

“Kermitops, with its unique anatomy, really exemplifies the importance of continuing to add new fossil data to understanding this evolutionary problem,” said National Museum of Natural History paleontologist and study co-author Arjan Mann.

Kermit the Frog was created by the late American puppeteer Jim Henson in 1955, and a Kermit puppet made in the 1970s is in the collection of the Smithsonian’s National Museum of American History as an important cultural object.

Kermitops means “Kermit face,” a nod to the Muppet’s humorous look.

“We thought that the eyelid bones gave the fossil a bug-eyed look, and combined with a lopsided smile produced by slight crushing during the preservation of the fossil, we really thought it looked like Kermit the Frog,” So said.

Kermitops belonged to a group called temnospondyls that arose a few tens of millions of years after the first land vertebrates evolved from fish ancestors. The biggest temnospondyls superficially resembled crocodiles, including two that each were around 6 meters in length, Prionosuchus and Mastodonsaurus.

Temnospondyls are considered the progenitor lineage of modern amphibians, Mann said.

Kermitops existed about 20 million years before the worst mass extinction in Earth’s history and about 40 million years before the first dinosaurs. It lived alongside other members of the amphibian lineage as well as the impressive sail-backed Dimetrodon, a predator related to the mammalian lineage.

The environment in which Kermitops lived appears to have alternated between warm and humid seasons and hot and arid seasons.

“This environment would be similar to modern-day monsoons that take place in the Southwest U.S. and Southeast Asia,” So said.

LONDON — As the United Nations observes World Water Day on Friday, there is a growing risk of conflict over water resources as climate change takes hold, the international body said.

Meanwhile, nongovernmental aid agency Oxfam accused global corporations of “grabbing” water from poorer countries to boost profits.

Declaring this year’s theme Water for Peace, the U.N. warned that “when water is scarce or polluted, or when people have unequal or no access, tensions can rise between communities and countries.”

“More than 3 billion people worldwide depend on water that crosses national borders. Yet only 24 countries have cooperation agreements for all their shared water,” the U.N. said. “As climate change impacts increase and populations grow, there is an urgent need within and between countries to unite around protecting and conserving our most precious resource.”

In South Africa’s largest city, Johannesburg, the taps have been running dry for several weeks, affecting millions of people.

On the outskirts of the city in Soweto, thousands of people have been lining up to collect water in bottles and buckets from tankers that bring in water from outside the city.

“It has been a serious challenge, a very challenging time for my age that I have to be here carrying these 20-liter buckets,” Thabisile Mchunu, an older Soweto resident, told The Associated Press on Monday. “And the sad thing is that we don’t know when our taps are going to be wet again.”

Crumbling infrastructure is partly to blame for the water shortages in Johannesburg. But scientists say worsening climate change is causing reservoirs to dry up in South Africa and many other parts of the world.

The United Nations estimates that 2.2 billion people live without safely managed drinking water.

Scientists from the U.N.’s Intergovernmental Panel on Climate Change say roughly half of the world’s population experiences severe water scarcity for at least part of the year, with poorer nations in the Global South the worst affected.

 

Water “grabbing”

In a report published Thursday, Oxfam accused major global corporations of “grabbing” vital water resources.

“The private sector is grabbing and polluting this resource at the expense of local populations in order to make profits, further increasing inequalities. Droughts exacerbated by climate change affect agriculture and therefore the economies of the countries that depend on it, contributing to increased poverty, food insecurity and health problems for the inhabitants, particularly in the Global South,” the report said.

Oxfam accuses richer countries and multinational corporations of shifting water shortages to poorer regions by importing water-intensive products such as fruit, vegetables, meat, flowers and bottled water from overseas.

The report says agriculture accounts for 70% of water withdrawals, including through irrigation systems, to support the meat industry and biofuels.

“It is part of a neocolonial logic aimed at satisfying the consumption needs of the countries of the North at the expense of the countries of the South,” Oxfam said.

Its analysis suggests the private sector is failing to reduce its impact on water resources.

Of the “350 corporations that have been analyzed through the database — which account for half of the world’s agricultural revenue — only one in four of them are declaring they are reducing water use and pollution,” Quentin Ghesquiere, an agriculture and food safety adviser at Oxfam France, told VOA.

Government regulation

Oxfam also noted that large corporations are permitted to withdraw water, even when local populations face restrictions. It highlighted the activities of the French-owned multinational food products company Danone.

“Danone, in May 2023, continued to extract water from aquifers [in France] despite the restrictions that applied to local populations, in full legality. In the same year, the company made profits of almost 900 million euros and paid out 1.2 billion euros in dividends to its shareholders,” the Oxfam report said.

In a statement to VOA, Danone said that managing water sustainably is a priority, adding that “we have accelerated our innovations and investments to reduce, on a voluntary basis, water withdrawals from our bottling site.”

“Since 2017, we have invested 30 million euros to modernize our production lines, which allowed us to reduce our withdrawals by 17% over the period 2017-2023, maintaining volumes sold,” the Danone statement said.

The Oxfam report recommends stronger regulation and calls for “ambitious funding for adaptation in developing countries and universal access to water.”
