Near-record hot year seen as a warning by scientists.

Five climate monitoring groups reported 2025 as the third-warmest year on record, with global average temperatures near 1.47°C above pre-industrial levels; researchers say recent years show an accelerating warming trend.

Scientists reported that 2025 was the third-hottest year on record. Multiple monitoring teams said the year's global average temperature hovered around 1.47°C above pre-industrial levels. Researchers noted the last 11 years are the warmest on record and that the recent three-year run departs from the earlier linear warming trend. Scientists attribute most of the warming to human greenhouse gas emissions. Key findings: - Five monitoring groups calculated 2025 as the third-warmest year, behind 2024 and 2023. - Global average temperatures for 2025 were reported near 1.47°C above pre-industrial levels, and the last 11 years are the warmest on record. - U.S. climate teams and the World Meteorological Organization were scheduled to release related reports the following day, and some groups estimate the long-term average could cross 1.5°C within this decade. Summary: Scientists describe 2025 as a warning sign of accelerating global warming and note that higher average temperatures are linked with more frequent and intense extreme weather. Several monitoring groups expect 2026 to be similarly warm, and some analyses point to a likely long-term breach of the 1.5°C threshold by around 2029.
