Overview
- The 2025 analysis estimates an average 546,000 heat-related deaths each year from 2012–2021, about 154,000 deaths from wildfire smoke in 2024, and more than 2.5 million deaths from outdoor fossil-fuel air pollution in 2022.
- Researchers report 13 of 20 tracked health indicators at record levels, reflecting escalating risks as global temperatures continue to rise.
- Global fossil-fuel consumption set a new high in 2024, with many governments still providing substantial subsidies to oil, gas and coal.
- In 2023, 15 of 87 high-emitting countries spent more on net fossil-fuel subsidies than on their national health budgets.
- The report describes weakening climate adaptation finance from wealthy nations—tied in part to U.S. cuts under President Donald Trump and similar trends in Germany and France—as major private lenders raised fossil-fuel financing to $611 billion in 2024.
