Executive Summary
Global temperatures in 2024 and 2025 stayed near record highs, with ocean heat, sea level rise, and ice loss showing climate change intensifying
- 2025 ranked among the three warmest years on record, with global surface temperatures about 1.44 C above pre-industrial levels
- Eight independent datasets put 2025 as second or third warmest since mid-1800s, with very small differences from 2023
- Ocean heat content hit a record high in 2025 and oceans absorbed more than 90 percent of trapped heat
- Global sea levels reached record highs, continuing a long-term acceleration over the past three decades
- Glaciers and the Greenland ice sheet lost more ice in 2025, adding to sea level rise
- Greenhouse gas concentrations of carbon dioxide, methane and nitrous oxide reached record levels
- Arctic and Antarctic sea ice saw unusually low extents, reflecting broad cryosphere decline
Quick Facts
- What: Reports confirmed near record global warming and ocean heat
- Where: Worldwide across land, oceans, and ice regions
- Why: Rising greenhouse gases kept trapping more heat
- Who: WMO, Carbon Brief, and climate datasets
- When: 2024 and 2025, with 2026 outlooks
