2026 Accelerating atmospheric greenhouse gas concentrations and global warming
May 2025 was the 21st month in a 22-month period for which the global-average surface air temperature was more than 1.5°C above pre-industrial levels. The run was broken by June 2025.
2025 The global average temperature for the 12-month period ending in November 2025 (December 2024 to November 2025) was 1.49°C
above pre-industrial. (Copernicus)

Global warming
2025 is a 1.5°C year
From January to November 2025 the global temperature increase is 1.5°C and mostly above, except November at 1.49°C.

Atmospheric greenhouse gas concentrations drive global warming.
All record high, increasing as fast as evrer, some faster
CO2 is responsible for about two thirds of global heating and all the ocean acidification.

For the 1.5°C limit and for the 2°C limit
global GHG emissions decline by
2025 at the latest.
