Global emissions have to decline by Immediate action (by 2025) 1.5°C AND 2°C limits (1.5C now way too late) (IPCC 6th Assessment, WG3, SPM C.1) Dedicated to the world's children
2024 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. April 2025 was 1.51°C warmer than pre-industrial April average for 1850-1900 (Copernicus)
Global warming June 2025 ended the recent global warming acceleration, dropping to 1.3C. As of June 2025, globally the annual average for the latest 12-month period was 1.55°C above 1850-1900 (Copernicus)
Atmospheric greenhouse gas concentrations drive global warming. All are record high and increasing at accelerating rates.
CO2 is responsible for about two thirds of global heating and all the ocean acidification.
Mitigation of climate change
IPCC AR6 For the 1.5C limit and for the 2C limit global GHG emissions decline by 2025 at the latest.
GLOBAL EMISSIONS Global emissions of CO2 and the greenhouse gases all together (atmospheric CO2 equivalent) are Record high- Increasing as from 1990
