Overview
- Updated analyses find global warming now running at about 0.27°C per decade, with records set across 2023–2025 and scientists projecting a 1.5°C breach around 2030.
- Sea levels have accelerated to roughly 4.5 millimeters per year over the past decade, while the World Meteorological Organization estimates total warming at 1.3–1.4°C since pre-industrial times.
- Evidence of tipping-point risks is growing, including near-irreversible warm-water coral die-offs, warnings of Amazon dieback, declining Antarctic sea ice, and potential AMOC disruption linked to Greenland meltwater.
- The 2025 State of Wildfires report tallies about 3.7 million square kilometers burned from March 2024 to February 2025, with higher CO2 emissions as more carbon-dense forests went up in flames.
- Researchers estimate 24,400 heat-related deaths this summer in parts of Europe, 62,700 across 32 countries last year, and more than $1 trillion in 2024 productivity losses, while the U.S. 2026 budget proposal would slash NASA and NOAA climate programs as other nations boost science funding.
