By Simon Jessop and Anna Portella BELEM, Brazil (Reuters) -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 incident folded into the greater drama playing out at COP30 — the 30th U.N. Climate Conference — where the complex, sprawling geopolitical and economic policy concerns underlying climate action rub against the deep anguish and alarm of climate activists.

A coalition of climate groups said they have identified more than 1,600 lobbyists for fossil fuels at the COP30 climate talks.

At COP30 in Belem, countries have rallied behind proposals for a roadmap to transition away from fossil fuels.

A top UN climate official demanded Brazilian authorities immediately develop a plan for addressing security lapses, soaring temperatures, flooding and other poor conditions at the COP30 conference in the city of Belém.

Launched at COP28 and implemented by the Oil and Gas Climate Initiative (OGCI), the Oil & Gas Decarbonization Charter (OGDC) is a global industry pledge to accelerate the reduction of Scope 1 and 2 emissions across the oil and gas sector.

At the COP30 climate summit in Brazil, Pacific Island states are making a familiar plea to keep warming at 1.5°C. But now they have the backing of a legal opinion that has transformed climate action from a moral and political aspiration into an obligation under international law.

Campaigners say Loss and Damage Fund, agreed at Cop27 in 2022, is under-funded, too restrictive and too slow to respond
