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For the new study, which has not yet been peer-reviewed, a U.S. team of researchers looked at how hotter temperatures were linked to dengue infections in 21 countries across Asia and the Americas.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Another set of research, also not peer-reviewed, raised hopes of a potential tool to help fight the rise of dengue.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.”

WINCHESTER, England — In the half-light of dusk, Martin Edwards surveys the shadows of the ancient woodland from a high seat and waits. He sits still, watching with his thermal camera.

Even the hares don’t seem to notice the deer stalker until he takes aim. The bang of his rifle pierces the stillness. He’s killed a buck, one of many wild deer roaming this patch of forest in Hampshire, southern England.

Edwards advocates humane deer management: the culling of deer to control their numbers and ensure they don’t overrun forests and farmland in a country where they no longer have natural predators. For these advocates, shooting deer is much more than a sport. It’s a necessity because England’s deer population has gotten out of control.

There are now more deer in England than at any other time in the last 1,000 years, according to the Forestry Commission, the government department looking after England’s public woodland.

That has had a devastating impact on the environment, officials say. Excessive deer foraging damages large areas of woodland including young trees, as well as the habitats of certain birds like robins. Some landowners have lost huge amounts of crops to deer, and overpopulation means that the mammals are more likely to suffer from starvation and disease.

“They will produce more young every year. We’ve got to a point where farmers and foresters are definitely seeing that impact,” said Edwards, pointing to some young hazel shrubs with half-eaten buds. “If there’s too many deer, you will see that they’ve literally eaten all the vegetation up to a certain height.”

Forestry experts and businesses argue that culling the deer — and supplying the meat to consumers — is a double win: It helps rebalance the ecosystem and provides a low-fat, sustainable protein.

While venison — a red meat similar to lean beef but with an earthier flavor — is often perceived as a high-end food in the U.K., one charity sees it as an ideal protein for those who can’t afford to buy other meats.

“Why not utilize that fantastic meat to feed people in need?” said SJ Hunt, chief executive of The Country Food Trust, which distributes meals made with wild venison to food banks.

Pandemic population boom

An estimated 2 million deer now roam England’s forests.

The government says native wild deer play a role in healthy forest ecosystems, but acknowledges that their population needs managing. It provides some funding for solutions such as building deer fences.

But experts like Edwards, a spokesman for the British Association for Shooting and Conservation, believe lethal control is the only effective option, especially after deer populations surged during the COVID-19 pandemic.

The pandemic was a boon to deer because hunters, like everyone else, stayed home and the restaurant market — the main outlet for venison in the U.K. — vanished overnight.

“There were no sales of venison and the price was absolutely on the floor,” said Ben Rigby, a leading venison and game meats wholesaler. “The deer had a chance to breed massively.”

Rigby’s company now processes hundreds of deer a week, turning them into diced venison or steaks for restaurants and supermarkets. One challenge, he said, is growing the domestic appetite for venison so it appears on more dinner plates, especially after Brexit put new barriers up for exporting the meat.

“We’re not really a game-eating nation, not like in France or Germany or Scandinavia,” he said. “But the U.K. is becoming more and more aware of it and our trade is growing.”

From the forest to the table

Shooting deer is legal but strictly regulated in England. Stalkers must have a license, use certain kinds of firearms and observe open seasons. They also need a valid reason, such as when a landowner authorizes them to kill the deer when their land is damaged. Hunting deer with packs of dogs is illegal.

Making wild venison more widely available in supermarkets and beyond will motivate more stalkers to cull the deer and ensure the meat doesn’t go to waste, Edwards said.

Forestry England, which manages public forests, is part of that drive. In recent years it supplied some hospitals with 1,000 kilograms of wild venison, which became the basis of pies and casseroles popular with patients and staff, it said.

The approach appears to have been well received, though it has attracted some criticism from animal welfare group PETA, which advocates veganism.

Hunt, the food charity chief, said there’s potential to do much more with the meat, which she described as nutritious and “free-range to the purest form of that definition.”

Her charity distributed hundreds of thousands of pouches of venison Bolognese meals to food banks last year — and people are hungry for more, she said.

She recalled attending one food bank session where the only protein available was canned sardines, canned baked beans and the venison meals.

“There were no eggs. There was no cheese. That’s all that they could do, and people were just saying, ‘Thank you, please bring more (of the venison),” she said. “That’s fantastic, because people realize they’re doing a double positive with helping the environment by utilizing the meat as well.”
