With more than a half-million people worldwide dying from heat-related causes every year, a group of philanthropies is putting $300 million into developing life-saving solutions as global temperatures continue to rise.

The money, announced this week at the COP30 climate negotiations in Brazil, is aimed at developing data and figuring out the best investments for tackling rising risks from extreme heat, air pollution and infectious disease.

"We are a philanthropy. We can't just keep plugging holes and resuscitating a dying model of development," said Estelle Willie, the director of health policy and communications at The Rockefeller Foundation, one of the funders.

"So what we are trying to do is through our philanthropy capital, we can start testing and validating new solutions through this work and coming together," she said.

Separately, COP30 host Brazil launched an initiative called the Belem Health Action Plan to encourage countries to monitor and coordinate climate-related health policy across their various ministries and departments, reports Reuters.

According to a report by Oil Change International, Azerbaijan, Kazakhstan and the United States shipped vast amounts of oil to Israel during its two-year Gaza offensive, which says the same fossil-fuel system driving climate change is also enabling "genocide."

Released at the UN climate summit in Brazil, the analysis titled "Behind the Barrel" found that 25 countries were responsible for 323 shipments of crude and refined petroleum products totaling 21.2 million tonnes between November 1, 2023, and October 1, 2025.

Meanwhile, lobbyists tied to the fossil fuel industry have turned up in strength at the UN climate talks in the Brazilian Amazon, an NGO coalition said yesterday, warning that their presence undermines the process.

A total of 1,602 delegates with links to the oil, gas and coal sectors have headed to Belem, equivalent to around one in 25 participants, according to Kick Big Polluters Out (KBPO), which analyzed the list of attendees.

Brazil has pushed back against a complaint by the UN's climate chief over a security breach at the COP30 summit in Belem, saying responsibility for safeguarding the venue's interior lies with the world body itself, reports AFP.

Simon Stiell, executive secretary of the UN Framework Convention on Climate Change, criticised the host nation's security personnel for "failing to act" on Tuesday night when dozens of Indigenous protesters forced their way inside, according to a letter reported by Bloomberg News.

His letter, addressed to Brazilian President Luiz Inacio Lula da Silva's chief of staff and to Andre Correa do Lago, the diplomat presiding over the summit, accused the hosts of a "serious breach of the established security framework".

In its response, seen by AFP, Brazil said: "Internal security within the Blue Zone is the responsibility of the UN Department of Safety and Security (UNDSS), which defines how all areas within it will be protected."
