California’s public health department reported a possible case of bird flu in a child with mild respiratory symptoms on Tuesday, but said there was no evidence of human-to-human transmission of the virus and that the child’s family members tested negative.

California officials said they have sent test specimens from the child to the U.S. Centers for Disease Control and Prevention for confirmation.

A CDC spokesperson said the agency is aware of the presumptive positive case of H5 avian influenza, is collaborating with the state’s investigation, and will provide further updates promptly. The agency has said the risk to the general public remains low.

Although human infections in the United States have been rare, bird flu has infected 53 people since April, according to the CDC, most recently a person in Oregon last week tied to a bird flu outbreak in a commercial poultry operation in the state.

In Canada, officials earlier this month reported that a teen infected with bird flu in British Columbia was in critical condition.

The child in California was in daycare with mild symptoms before the illness was reported, the state said.

Local health officials have contacted potentially exposed caregivers and families to check for symptoms and offer preventive treatment and testing if they become symptomatic.

The child and all close family members have been treated with preventive medication, the state said. The child had no known contact with an infected animal, but public health experts are investigating possible exposure to wild birds.

“It’s natural for people to be concerned, and we want to reinforce for parents, caregivers and families that based on the information and data we have, we don’t think the child was infectious,” said California health department director Dr. Tomas Aragon, adding, “and no human-to-human spread of bird flu has been documented in any country for more than 15 years.”

Most U.S. bird flu cases, including 26 in California, have occurred among farm workers working with poultry or dairy cows that were infected with the virus.

Because bird flu viruses can mutate and gain the ability to spread more easily between people, California public health officials said they are monitoring animal and human infections carefully.

The state urged residents to avoid contact with sick or dead wild birds and renewed the warning against consuming raw milk or raw milk products, which have not undergone pasteurization to inactivate the bird flu virus and other harmful pathogens.

London — As the COP29 climate summit in Baku, Azerbaijan enters its final days, there are growing frustrations over the apparent lack of progress toward securing a deal on climate finance, which is seen as a crucial step in reducing emissions and limiting global warming.

Mukhtar Babayev, Azerbaijan’s COP29 president, called on delegates to show more urgency.

“People have told me that they are concerned about the state of the negotiations,” Babayev told delegates Monday. “It’s time for them to move faster. This week we will welcome ministers from around the world as the negotiations reach their final stage.

“Politicians have the power to reach a fair and ambitious deal. They must deliver on this responsibility. They must engage immediately and constructively,” he said.

Climate finance

Money is at the center of the COP29 negotiations — or, in COP terms, climate finance. Who will pay for poorer countries to adapt to climate change and transition away from fossil fuels — and how much will it cost?

It’s hoped that the COP29 meeting will set an ambitious new funding target. Most estimates put the cost of climate finance in excess of $1 trillion every year. It’s reported that many richer nations are reluctant to agree to such an amount.

The current target of $100 billion annually, agreed in 2009, was met only in 2022.

‘Failed promises’

Bolivia’s representative at COP29, Diego Balanza — who chairs a negotiating bloc of developing nations — accused richer nations of a decade of failed promises.

“Our countries are suffering the impacts of climate change due largely to the historical emissions of developed countries. For us as developing countries, our people’s lives, their very survival and their livelihoods, are at stake,” Balanza told delegates in Baku.

He added that most of the climate finance so far has been provided through loans, not grants, which “has adverse implications for the macroeconomic stability of developing countries.”

Slow pace

Many observers have criticized the slow pace of negotiations in Baku. Mohamed Adow, director of the campaign group Power Shift Africa, accused the Azerbaijani hosts of a lack of direction.

“This has been one of the worst COPs — at least, one of the worst first weeks of COPs — that I have attended in the last 15 years,” Adow told VOA. “There has been very limited progress on climate finance and even on the rules around carbon markets and how the world is going to cut emissions.”

‘Theatrics’

Simon Stiell, the United Nations Climate Change executive secretary, on Monday called on parties to “cut the theatrics.”

“There is still a ton of work to do to ensure COP29 delivers. Parties need to be moving much faster towards landing zones. … I’ve been very blunt: climate finance is not charity. It is 100% in every nation’s interest to protect their economies and people from rampant climate impacts. Parties must wrap up less contentious issues early in the week, so there is enough time for the major political decisions,” Stiell said.

Emissions cuts

An ambitious COP29 deal on climate finance is meant to unlock the crucial next stage of negotiations. Ahead of next year’s COP30 in Brazil, all countries are due to deliver action plans on reducing greenhouse gas emissions, so-called ‘nationally determined contributions,’ with the goal of limiting global warming to 1.5°C above pre-industrial levels, a key target of the 2016 Paris Agreement on climate change.

On the current trajectory, scientists estimate the world is heading for a likely catastrophic 2.7°C of warming by the end of the century, which is predicted to cause widespread extreme weather and sea level rise.

Trump shadow

Adow, the director of Power Shift Africa, fears the COP29 negotiations are being overshadowed by the recent U.S. presidential election win for Donald Trump.

Trump pulled the United States out of the Paris Agreement on climate change during his first term. His successor, Joe Biden, re-entered the deal on his first day in office.

“I think the cloud hovering over these talks is the known unknown, around the election of Donald Trump and what the Trump administration is going to do. So, you have the rich world, that is actually hiding behind Trump — and not wanting to respond to the calls that we’ve had from the developing countries on the US$1.3 trillion that they require for climate finance,” Adow told VOA.

The COP29 talks are due to close on Friday. The deadline could be extended if a deal is in sight.

NAIROBI, KENYA — The spread of a mosquito in East Africa that thrives in urban areas and is immune to insecticide is fueling a surge in malaria that could reverse decades of progress against the disease, experts say.

Africa accounted for about 95% of the 249 million malaria cases and 608,000 deaths worldwide in 2022, according to the most recent data from the World Health Organization (WHO), which said children under 5 accounted for 80% of deaths in the region.

But the emergence of an invasive species of mosquito on the continent could massively increase those numbers. 

Anopheles stephensi is native to parts of South Asia and the Middle East but was spotted for the first time in the tiny Horn of Africa state of Djibouti in 2012.

Djibouti had all but eradicated malaria only to see it make a slow but steady return over the following years, hitting more than 70,000 cases in 2020. 

Then stephensi arrived in neighboring Ethiopia and WHO says it is key to an “unprecedented surge,” from 4.1 million malaria cases and 527 deaths last year to 7.3 million cases and 1,157 deaths between January 1 and October 20, 2024.

Unlike other species which are seasonal and prefer rural areas, stephensi thrives year-round in urban settings, breeding in man-made water storage tanks, roof gutters or even air conditioning units.

It appears to be highly resistant to insecticides, and bites earlier in the evening than other carriers. That means bed nets — up to now the prime weapon against malaria — may be much less effective.

“The invasion and spread of Anopheles stephensi has the potential to change the malaria landscape in Africa and reverse decades of progress we’ve made towards malaria control,” Meera Venkatesan, malaria division chief for USAID, told AFP.

More research is needed

The fear is that stephensi will infest dense cities like Mombasa on Kenya’s Indian Ocean coast and Sudan’s capital Khartoum, with one 2020 study warning it could eventually reach 126 million city-dwellers across Africa.

Only last month, Egypt was declared malaria-free by WHO after a century-long battle against the disease — a status that could be threatened by stephensi’s arrival.

Much remains unknown, however.

Stephensi was confirmed as present in Kenya in late 2022, but has so far stayed in hotter, dryer areas without reaching the high-altitude capital, Nairobi. 

“We don’t yet fully understand the biology and behavior of this mosquito,” Charles Mbogo, president of the Pan-African Mosquito Control Association, told AFP.

“Possibly it is climate-driven and requires high temperatures, but much more research is needed.”

He called for increased funding for capturing and testing mosquitos, and for educating the public on prevention measures such as covering water receptacles.

Multiplying threats

The spread of stephensi could dovetail with other worrying trends, including increased evidence of drug resistant malaria recorded in Uganda, Rwanda, Tanzania and Eritrea.

“The arrival of resistance is imminent,” said Dorothy Achu, WHO’s head of tropical and vector-borne diseases in Africa. 

WHO is working with countries to diversify treatment programmes to delay resistance, she said. 

A new malaria variant is also evading tests used to diagnose the disease. 

“The increased transmission that stephensi is driving could potentially help accelerate the spread of other threats, such as drug resistance or another mutation in the parasite that leads it to be less detectable by our most widely-used diagnostics,” said Venkatesan at USAID.

Another added challenge is the lack of coordination between African governments. 

Achu said WHO is working on “a more continental approach”. 

But Mbogo in Kenya said “more political will” was needed. 

“We share information as scientists with colleagues in neighbouring countries,” he said. “But we need to reach the higher level. We need cross-border collaborations, data-sharing.”

warsaw, poland — Poland’s health authorities on Monday urged polio vaccinations for children after the virus was detected in Warsaw’s sewage during regular tests this month.

The state Main Sanitary Inspectorate in a statement said the presence of the virus does not necessarily mean people have been sick, but those who have not been vaccinated against polio could be at risk. The vaccinations are free in Poland for people under 19.

New measures also include more intensive testing of Warsaw’s sewage, renewing the vaccination stocks and updating the list of children still unvaccinated. Polio is most often spread by contact with waste from an infected person or, less frequently, through contaminated water or food.

The polio virus mostly affects children under 5. Most people infected don’t have symptoms, but in severe cases, polio can invade the nervous system and cause paralysis within hours, according to the World Health Organization. It estimates that 1 in 200 polio cases results in permanent paralysis, usually of the legs.

Poland’s inspectorate said about 86% of the country’s 3-year-olds have been vaccinated against polio and that vaccinating at least 95% of children can prevent the spread of the virus. Poland has seen the rise of anti-vaccination movements among some parents, which has worried health officials.

The statement said Poland’s last case of polio was in 1984.

BAKU, Azerbaijan — United Nations climate talks resumed Monday with negotiators urged to make progress on a stalled-out deal that could see developing countries get more money to spend on clean energy and adapting to climate-charged weather extremes.

U.N. Climate Change executive secretary Simon Stiell called for countries to “cut the theatrics and get down to real business.”

“We will only get the job done if Parties are prepared to step forward in parallel, bringing us closer to common ground,” Stiell said to a room of delegates in Baku, Azerbaijan. “I know we can get this done.”

Climate and environment ministers from around the world have arrived at the summit to help push the talks forward.

“Politicians have the power to reach a fair and ambitious deal,” said COP29 President Mukhtar Babayev at a press conference at the venue. “They must deliver and engage immediately and constructively.”

Climate cash is still a sticking point

Talks in Baku are focused on getting more climate cash for developing countries to transition away from fossil fuels, adapt to climate change and pay for damages caused by extreme weather. But countries are far apart on how much money that will require.

A group of developing nations last week put the sum at $1.3 trillion, while rich countries are yet to name a figure. Several experts estimated that the money needed for climate finance is around $1 trillion.

“We all know it is never easy in politics and in international politics to talk about money, but the cost of action today is, as a matter of fact, much lower than the cost of inaction,” said Wopke Hoekstra, the EU climate commissioner at press conference.

“We will continue to lead to do our fair share and even more than our fair share, as we’ve always done,” he said. But Hoekstra added that “others have a responsibility to contribute based on their emissions and based on their economic growth too.”

Teresa Anderson, the Global Lead on Climate Justice at ActionAid International, was skeptical about rich countries’ intentions.

“The concern is that the pressure to add developing countries to the list of contributors is not, in fact, about raising more money for frontline countries,” Anderson said. “Rich countries are just trying to point the finger and have an excuse to provide less finance. That’s not the way to address runaway climate breakdown, and is a distraction from the real issues at stake.”

Rachel Cleetus from the Union of Concerned Scientists said $1 trillion in global climate funds “is going to look like a bargain five, 10 years from now.”

“We’re going to wonder why we didn’t take that and run with it,” she said, citing a multitude of costly recent extreme weather events from flooding in Spain to hurricanes Helene and Milton in the United States.

Robert Habeck, Germany’s climate and economic affairs minister said rich nations shouldn’t try to stop developing nations from producing more energy, but it has to come from cleaner sources.

“They have the same right to create same work, same education and health system,” he said. “On other hand, if we’re they are doing the same as we did for 100 years of burning fossil energy, that is completely messed up.”

Climate watchers keep an eye on Rio and Paris

Meanwhile, the world’s biggest decision makers are halfway around the world as another major summit convenes. Brazil is hosting the Group of 20 summit, which runs Nov. 18-19, bringing together many of the world’s largest economies. Climate change — among other major topics like rising global tensions and poverty — will be on the agenda.

COP President Babayev said the world “cannot succeed” in its climate goals without G20 nations.

“We urge them to use the G20 meeting to send a positive signal of their commitment to addressing the climate crisis. We want them to provide clear mandates to deliver,” he said.

Harjeet Singh, global engagement director for the Fossil Fuel Non-Proliferation Treaty Initiative, said G20 nations “cannot turn their backs on the reality of their historical emissions and the responsibility that comes with it.”

“They must commit to trillions in public finance,” he said.

Also on Monday, the Paris-based Organization for Economic Cooperation and Development has been mulling a proposal to cut public spending for foreign fossil fuel projects. The OECD — made up of 38 member countries including the United States, the United Kingdom, South Korea, Japan and Germany — are discussing a deal that could prevent up to $40 billion worth of carbon-polluting projects.

At COP29, activists are protesting the U.S., South Korea, Japan, and Turkey who they say are the key holdouts preventing the agreement in Paris from being finalized.

“It’s of critical importance that President Biden comes out in support. We know it’s really important that he lands a deal that Trump cannot undo. This can be really important for Biden’s legacy,” said Lauri van der Burg, Global Public Finance Lead at Oil Change international. “If he comes around, this will help mount pressure on other laggards including Korea, Turkey and Japan.”

DAEJEON, South Korea — Imagine a wheelchair equipped with wheels flexible enough to navigate all manner of obstacles from curbs to humps and even staircases.  

Or perhaps an unmanned delivery vehicle using the same wheels that takes the stairs to deliver food and groceries right to your door. 

This is what researchers from the Korea Institute of Machinery and Materials (KIMM) envision for their “morphing” wheel, which can roll over obstacles up to 1.3 times the height of its radius.  

Inspired by the surface tension of water droplets, it goes from solid to fluid when it encounters impediments. 

Other possible applications include robots that spy on the enemy in the battlefield. 

The KIMM team also hopes that morphing wheels will eventually be used with two- and four-legged robots – currently limited in movement efficiency and susceptible to vibration – that can carry payloads that need stable movement in industrial settings. 

“The goal is to make this viable for speed up to 100 kph, or the speed of an average car,” said Song Sung-hyuk, principal researcher at KIMM. 

Wheels developed for a similar purpose such as nonpneumatic or airless tires have flexibility but are limited in their ability to overcome obstacles, said Song, who is a member of KIMM’s AI robotics research team.  

The morphing wheel consists of an outer hoop of a chain and a series of spoke wires running through the hub. The stiffness of the spokes – and hence the wheel – is automatically regulated by a sensor as it reacts to the terrain. 

Song’s team demonstrated to Reuters a prototype wheelchair mounted on morphing wheels as it climbed stairs with 18-cm steps with a life-size dummy sitting in it. The team has also tested a device mounted with the wheel at speeds of up to 30 kph. 

The morphing wheel was featured on the cover of the journal Science Robotics in August.

BEIJING/HONG KONG — A 22-year-old Chinese woman’s account of how she was lured into the country’s illegal surrogacy industry before suffering a miscarriage went viral on Chinese social media this week and raised heated debates over women’s rights and social inequality. 

Surrogacy is banned in China, and authorities have vowed to severely crack down on illegal practices, including the buying and selling of sperm, egg and surrogacy services. 

The incident comes as Chinese authorities grapple with how to increase the country’s birth rate as more young couples put off having children or opt to have none. 

China’s population fell for a second consecutive year in 2023 and Beijing in October rallied local governments to direct resources towards fixing China’s population crisis to create a “birth-friendly” society.  

Zhang Jing, 22, told state-backed Phoenix TV magazine that she donated her eggs out of financial desperation and then agreed to “rent out her uterus” to be impregnated for a total of 30,000 yuan ($4,152).  

If she “successfully” delivered the baby, she would be paid a total of 240,000 yuan. At five months pregnant, she experienced severe complications and had to have an abortion.  

Zhang’s story amassed more than 86 million views and 10,000 comments on Chinese social media platform Weibo, with the hashtag “#2000s-born Surrogate Miscarriage Girl Speaks Out#.” 

The majority of comments strongly opposed surrogacy. Some warned that legalizing surrogacy in China could lead to increased competition that would lower compensation and further devalue women. 

“No woman could escape this if surrogacy were legalized,” one user wrote, while another said, “Legalizing surrogacy would drive down prices and commodify women.” 

Zhang’s story ignited calls for a more thorough crackdown on illegal surrogacy by authorities, with some commenters warning that allowing the black market to continue to operate could even normalize human organ trafficking.  

“Life should not be traded as a commodity,” one user wrote. “If this extends to the sale of organs, it will only get darker and darker, and women will have no future.” 

The incident comes a few weeks after a 28-year-old pregnant woman who acted as a surrogate in China’s southwestern city of Chengdu was allegedly abandoned by her surrogacy agency.

U.S. President-elect Donald Trump has selected Chris Wright, the founder of an oilfield services company, to lead the Energy Department, as his new administration continues to take shape. 

The transition team officially announced the choice on Saturday afternoon. On Friday, Trump announced a new National Energy Council to be led by his Interior Department pick, former North Dakota Governor Doug Burgum.

In this role, Burgum will direct a panel that crosses all executive branch agencies involved in energy permitting, production, generation, distribution, regulation and transportation, Trump said in a statement. As chairman of the National Energy Council, Burgum will have a seat on the National Security Council, the president-elect said. 

Wright, the CEO of Liberty Energy based in Denver, Colorado, has no political experience. He is an advocate for the oil and gas industry, including fracking. In 2019, he drank fracking liquid to show that it was not dangerous. 

According to a March 2024 report by the U.S. Energy Information Administration, the U.S. has produced more crude oil than any nation at any time, according to its International Energy Statistics, for the past six years in a row. Average monthly U.S. crude oil production established a monthly record high in December 2023 at more than 13.3 million barrels per day. 

Earlier announcements 

The Trump-Vance transition team announced Steven Cheung will return to the Trump White House as communications director. He held the same position for the Trump-Vance 2024 presidential campaign and served in the White House during Trump’s first term as director of strategic response.   

On Friday evening, Trump announced that his campaign press secretary, Karoline Leavitt, would be his White House press secretary. She served as assistant press secretary in his previous term in office. 

Trump has swiftly named an array of political loyalists to key Cabinet positions. Most of them are likely to win quick Senate approval after confirmation hearings.  

Having won majorities in both the U.S. House of Representatives and the U.S. Senate, Republicans are set to take full control of the U.S. government by the third week in January.  

“Republicans in the House and Senate have a mandate,” newly reelected House Speaker Mike Johnson said earlier this week. “The American people want us to implement and deliver that ‘America First’ agenda.” 

Trump will be sworn in as the country’s 47th president on January 20, two weeks after the new Congress has been seated.  

The 78-year-old Trump campaigned on a sweeping agenda that Democrats will be largely powerless to stop.  

Republicans will have a 53-47 edge in the Senate, and the tie-breaking vote of Vice President-elect JD Vance in the event of a 50-50 stalemate on any legislative proposal. Republicans have secured at least 218 seats in the 435-member House, pending the outcome of seven undecided elections for two-year terms.   

During his bid to win a second, nonconsecutive four-year term, Trump called for the massive deportation of millions of undocumented migrants living in the United States to their home countries, an extension and expansion of 2017 tax cuts that are set to expire at the end of 2025, further deregulation of businesses, a curb on climate controls, and prosecution of his political opponents.  

Senator John Thune of South Dakota, newly elected by his fellow Republicans as the Senate majority leader, said, “This Republican team is united. We are on one team. We are excited to reclaim the majority and to get to work with our colleagues in the House to enact President Trump’s agenda.”  

Trump also has called on Senate Republican leaders to allow him to make “recess appointments,” which could occur when the chamber is not in session and would erase the need for time-consuming and often contentious confirmation hearings.  

Despite the likelihood that most of his nominees will be approved, Trump this week named four who immediately drew disparaging assessments from several Democrats and some Republicans for their perceived lack of credentials.  

They are former Representative Matt Gaetz as attorney general; former Democratic congresswoman turned Republican Tulsi Gabbard as director of national intelligence; former junior military officer and Fox News host Pete Hegseth as defense secretary; and former presidential candidate and anti-vaccine activist Robert F. Kennedy Jr. to lead the Health and Human Services Department.  

The blowback presages tough confirmation fights for the four in the Senate, which reviews the appointments of top-level officials and then votes to confirm them or, on occasion, reject them, forcing the White House to make another choice.  

The appointment of Gaetz, 42, could prove particularly problematic, with some senators openly questioning whether he can win a 51-vote majority to assume the government’s top law enforcement position. 

A House ethics committee probe was in the final stages of investigating whether he engaged in sexual misconduct and illicit drug use when he announced his resignation from the chamber late Wednesday, ending the probe. 

The Justice Department that Gaetz hopes to lead had decided not to pursue criminal charges. Gaetz has denied all wrongdoing. 

Gabbard, 43, has been criticized for her lack of direct experience in intelligence and accused of disseminating pro-Russian disinformation. If confirmed, she would be tasked with overseeing 18 U.S. intelligence agencies. She won over Trump with her switch from being a one-time Democratic House member from Hawaii to changing parties and staunchly advocating for his election. 

Critics have assailed Hegseth, a 44-year-old decorated former military officer, as someone who lacks managerial experience in the business world. A weekend anchor on Fox News, he has voiced his opinions on military operations, including his opposition to women serving in combat roles. 

A descendant of the Kennedy family political dynasty, Kennedy, 70, for years has been one of the country’s most prominent proponents of anti-vaccine views. He also opposed water fluoridation. 

On Thursday, Trump also selected former Securities and Exchange Commission Chairman Jay Clayton to be Manhattan’s top federal prosecutor, and former Representative Doug Collins to be secretary of the Department of Veterans Affairs. 

Trump named one of his personal criminal defense attorneys, Todd Blanche, to be deputy attorney general, and another of his attorneys, D. John Sauer, to be solicitor general.

NEW YORK — Health officials said Saturday they have confirmed the first U.S. case of a new form of mpox that was first seen in eastern Congo. 

The person had traveled to eastern Africa and was treated in Northern California upon return, according to the California Department of Public Health. Symptoms are improving and the risk to the public is low. 

The individual was isolating at home and health workers are reaching out to close contacts as a precaution, the state health department said. 

Mpox is a rare disease caused by infection with a virus that’s in the same family as the one that causes smallpox. It is endemic in parts of Africa, where people have been infected through bites from rodents or small animals. Milder symptoms can include fever, chills and body aches. In more serious cases, people can develop lesions on the face, hands, chest and genitals. 

Earlier this year, scientists reported the emergence of a new form of mpox in Africa that was spread through close contact including through sex. It was widely transmitted in eastern and central Africa. But in cases that were identified in travelers outside of the continent, spread has been very limited, according to the U.S. Centers for Disease Control and Prevention. 

More than 3,100 confirmed cases have been reported since late September, according to the World Health Organization. Most of them have been in three African countries — Burundi, Uganda, and the Democratic Republic of the Congo. 

Since then, cases of travelers with the new mpox form have been reported in Germany, India, Kenya, Sweden, Thailand, Zimbabwe, and the United Kingdom. 

Health officials earlier this month said the situation in Congo appears to be stabilizing. The Africa CDC has estimated Congo needs at least 3 million mpox vaccines to stop the spread, and another 7 million vaccines for the rest of Africa. The spread is mostly through sexual transmission as well as through close contact among children, pregnant women and other vulnerable groups. 

The current outbreak is different from the 2022 global outbreak of mpox where gay and bisexual men made up most of the cases.

paris — Climate change is responsible for nearly a fifth of the record number of dengue cases worldwide this year, U.S. researchers said Saturday, seeking to shine a light on how rising temperatures help spread disease. 

Researchers have been working to demonstrate how human-driven climate change directly contributes to individual extreme weather events such as the hurricanes, fires, droughts and floods that have battered the world this year. 

But linking how global warming affects health — such as driving outbreaks or spreading disease — remains a new field. 

“Dengue is a really good first disease to focus on because it’s very climate sensitive,” Erin Mordecai, an infectious disease ecologist at Stanford University, told AFP. 

The viral disease, which is transmitted via bites from infected mosquitoes, causes fever and body aches and can, in some cases, be deadly. 

It has typically been confined to tropical and sub-tropical areas but rising temperatures have led to mosquitoes encroaching on new areas, taking dengue with them. 

For the new study, which has not yet been peer-reviewed, a U.S. team of researchers looked at how hotter temperatures were linked to dengue infections in 21 countries across Asia and the Americas. 

On average, around 19% of current dengue cases around the world are “attributable to climate warming that has already happened,” said Mordecai, the senior author of the pre-print study. 

Temperatures between 20-29 degrees Celsius (68-84 degrees Fahrenheit) are ideal for spreading dengue, Mordecai said. 

Elevated areas of Peru, Mexico, Bolivia and Brazil that will warm into this temperature range could see dengue cases rising by as much as 200% in the next 25 years, the researchers found. 

The analysis estimated that at least 257 million people are currently living in areas where global warming could double the rate of dengue during that period. 

This danger is just “another reason you should care about climate change,” Mordecai said. 

More than 12.7 million dengue cases were recorded worldwide this year as of September, nearly double 2023’s total record, according to World Health Organization figures. 

But Mordecai said a “massive amount of under-reporting” meant the real number was likely to be closer to 100 million. 

The research was presented at the annual meeting of the American Society of Tropical Medicine and Hygiene in the city of New Orleans, in the U.S. state of Louisiana.

Another set of research, also not peer-reviewed, raised hopes of a potential tool to help fight the rise of dengue. 

It involves breeding mosquitoes infected with a common bacteria called Wolbachia that can block the insect’s ability to transmit dengue. 

Five years ago, Wolbachia-infected mosquitoes were introduced across most of the Brazilian city of Niteroi. 

When Brazil endured its worst-ever dengue outbreak this year, there was only a small increase in dengue in Niteroi, they found. 

The number of cases was also 90% lower than before the Wolbachia mosquitoes were deployed — and “nothing like what was happening in the rest of Brazil,” said Katie Anders of the World Mosquito Program. 

That the city fared so well showed that “Wolbachia can provide long-term protection for communities against the increasingly frequent surges in dengue that we’re seeing globally,” Anders said. 

The researchers said they have partnered with the Brazilian government to build a Wolbachia mosquitoes production facility in hopes of protecting millions of people.

RIO DE JANEIRO — As Brazil prepares to welcome leaders from the world’s 20 largest economies for the Group of 20 summit, another event is taking place in Rio de Janeiro, one that brings global civil society to together for pivotal discussions.

The Brazil G20 Social Summit, an initiative by the Brazilian government, marks the first event at which citizens from around the world, as well as nonprofits and community organizations, are invited to participate in a series of smaller conferences.

One of the most talked-about initiatives is the launch of the Global Alliance Against Hunger — a group proposed by Brazil’s government to raise funds and implement policies aimed at reducing hunger worldwide.

Wellington Dias, Brazil’s minister of Development and Social Assistance, Family and Combating Hunger, told VOA this initiative is open to any nation. He said the G20 addressing hunger and poverty is a significant challenge and a new development.

Dias said the recent COVID pandemic and climate change created a problem for the world.

“It further disrupted the immigration process,” Dias said in an interview in Portuguese. “We also began to face situations involving climate change and people referred to as climate refugees. Hence, the need to address this issue.”

Brazil, Ghana, Zimbabwe, Kenya, Chile, Indonesia and the Dominican Republic have outlined their strategies. Countries supporting these efforts include Germany, France, the United Kingdom, Norway and Spain, as well as the European Union and organizations such as the World Bank, the Food and Agriculture Organization and the World Food Program.

Proposed measures include expanding cash transfer programs to support 500 million people, providing school meals to an additional 150 million children and offering health services to 200 million women and children younger than 6.

“What we need to solve hunger is much less than what is allocated to wars [and conflicts]. … The goal here is to develop a solution tailored to each country’s needs. It’s not just about distributing food baskets but also about delivering a development plan,” Dias said.

Brazilian officials said this financial commitment is expected to come from about 40 nation members of the alliance, 13 international organizations and financial institutions, 19 large philanthropic foundations, civil society organizations, nongovernmental organizations and other nonprofit organizations.

Dias said the alliance is expected to reach its target of 100 countries in the coming months, with more than 50 nations preparing plans to join. However, he said to join the alliance, countries must present well-defined plans and proven projects that effectively reduce poverty.

According to the United Nations, the relationship between food insecurity, migration and displacement is heavily influenced by factors such as conflict, climate change, natural disasters and poverty.

Current projections show that by 2030, 622 million people will live below the World Bank’s extreme poverty line of $2.15 a day.

The alliance’s mission is to lift at least 600 million people out of poverty by 2030.

The G20 social proposals will be compiled into a final document to be presented at the G20 leaders’ summit on Monday and Tuesday, hosted by Brazil. The Brazilian government has prioritized the fight against world hunger, alongside addressing climate change and anti-corruption governance reform.

South African Ambassador Nosipho Jezile told VOA: “Brazil has inspired me and [other] leaders in the context of this global alliance against hunger and poverty. It’s quite a stretch goal in terms of dealing with the challenges in hand.”

But she said nations know the problem and have evidence-based solutions.

“All we have to do is collaborate and make it happen. … It needs a lot of money, but of course, the reorientation of resources that are available to enable and deal with 500 million people that are in hunger and that’s what we have in this commitment,” she said.

About 47,000 people attended the G20 Social Summit from Thursday to Saturday, engaging in discussions on inequality and climate change.

“So, beyond the immigration issue, I always argue that hunger and extreme poverty are not just problems for those experiencing them — they are problems for the middle class, for the wealthy, for rich countries, and for rich individuals. There will be no social peace in the world if we do not find a solution to this issue,” Dias told VOA.

BAKU, AZERBAIJAN — Hundreds of activists formed a human chain outside one of the main plenary halls at the United Nations climate summit on what is traditionally their biggest protest day during the two-week talks.

The demonstration in Baku, Azerbaijan, will be echoed at sites around the world in a global “day of action” for climate justice that’s become an annual event.

Activists waved flags, snapped their fingers, hummed and mumbled chants, with many covering their mouths with the word “Silenced.”

Demonstrators held up signs calling for more money to be pledged for climate finance, which involves cash for transitioning to clean energy and adapting to climate change. It comes as negotiators at the venue try to hammer out a deal for exactly that — but progress has been slow, and observers say the direction of any agreement is still unclear.

‘Keep fighting’

Lidy Nacpil said protestors like her are “not surprised” about how negotiations are going. But past wins — such as a loss and damage fund that gives developing nations cash after extreme weather events exacerbated by climate change — keep organizers going, said Nacpil, a coordinator with the Asian Peoples’ Movement on Debt and Development.

“The role we play is to increase the pressure,” she said of the action. “We know we’re not going to get the results that the world needs in this round of negotiations, but at least to bring us many steps closer is our hope, is our aim.

“I think we have no option but to keep fighting. … It’s the instinctive response that anyone, any living being, living creatures will have, which is to fight for life and fight for survival.”

Tasneem Essop said she was inspired by the action, which was challenging to organize. “To be able to pull off something where people feel their own power, exercise their own power and get inspired in this creative way, I’m super excited about this,” she said.

Essop said she’s “not very” optimistic about an outcome on finance but knows next week will be pivotal. “We can’t end up with a bad deal for the peoples of the world, those who are already suffering the impacts of climate change, those who need to adapt to an increasing and escalating crisis,” she said.

“We fight until the end.”

Climate cash

Negotiators at COP29, as the talks are known, are working on a deal that might be worth hundreds of billions of dollars to poorer nations. Many are in the Global South and already suffering the costly impact of weather disasters fueled by climate change. Several experts have said $1 trillion or more annually is needed both to compensate for such damages and to pay for a clean-energy transition that most countries can’t afford on their own.

Samir Bejanov, deputy lead negotiator of this year’s climate talks, said in a press conference that the climate finance talks were moving too slowly.

“I want to repeat our strong encouragement to all parties to make as much progress as possible,” he said. “We need everyone to approach the task with urgency and determination.”

Diego Pacheco, a negotiator from Bolivia, said the amount of money on the table for developing countries needs to be “loud and clear.”

“No more speeches but real money,” he said.

Observers also were disappointed at the pace of progress.

“This has been the worst first week of a COP in my 15 years of attending this summit,” said Mohamed Adow, of climate think tank Power Shift Africa. “There’s no clarity on the climate finance goal, the quality of the finance or how it’s going to be made accessible to vulnerable countries.

“I sense a lot of frustration, especially among the developing country blocs here,” he said.

Panama environment minister Juan Carlos Navarro agreed, telling The Associated Press he is “not encouraged” by what he’s seeing at COP29 so far.

“What I see is a lot of talk and very little action,” he said, noting that Panama is among the group of countries least responsible for warming emissions but most vulnerable to the damage caused by climate change-fueled disasters.

BAKU, AZERBAIJAN — The United Nation’s climate chief urged G20 nations on Saturday to push COP29 negotiations toward a deal to raise money for developing nations, warning there was a “long way to go.”

Negotiators worked through the night to narrow their differences at the U.N. talks in Baku before ministers arrive next week for the final days of the summit, but major differences remain.

U.N. climate chief Simon Stiell appealed for leaders of the Group of 20 nations, which includes the world’s biggest economies and top polluters, to weigh in when they meet in Brazil on Monday.

“As G20 Leaders head to Rio de Janeiro, the world is watching and expecting strong signals that climate action is core business for the world’s biggest economies,” Stiell said in a statement.

Some developing countries, which are least responsible for global greenhouse gas emissions, want an annual commitment of $1.3 trillion to help them adapt to climate impact and transition to clean energy.

The figure is over 10 times what donors including the United States, the European Union and Japan currently pay.

But the negotiations are stuck over a final figure, the type of financing and who should pay, with developed countries wanting China and wealthy Gulf states to join the list of donors.

The latest draft deal was 25 pages long and still contained a raft of options.

“Here in Baku negotiators are working around the clock on a new climate finance goal,” Stiell said.

“There is a long way to go, but everyone is very aware of the stakes, at the halfway point in the COP,” he said.

“Climate finance progress outside of our process is equally crucial, and the G20’s role is mission-critical.”
