2024 Accelerating greenhouse gas emissions
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 Global temperature was averaged at. 1.44°C by WMO,
and 1.47°C by NASA GISS and Copernicus.

2024 was the global warming record year at 1.55°C
From January to November 2025 the globa temperature increase was 1.5°C and mostly above, except November at 1.49°C.

Atmospheric greenhouse gas concentration (CO2 eq.) drives global warming.
It is record high (519 ppm CO2eq) and accelerating
CO2 is responsible for about two thirds of global heating and all the ocean acidification.

GLOBAL GHG EMISSIONS
2024 Global CO2 equivalent emissions- (of CO2 and the other main greenhouse gases all together) are record high (519 ppm CO2 eq.)

Global temperatures from the past three years (2023-2025) averaged more than 1.5°C above the pre-industrial level (1850–1900). This marks the first time a three-year period has exceeded the 1.5°C limit. Air temperature over global land areas was second warmest, whilst the Antarctic saw its warmest annual temperature on record and the Arctic its 2nd warmest (Copernicus)
The 1.5°C danger limit is broken, and 2°C is being broken, which James Hansen
says will be in the 2030s, not 2050 (as IPCC)
