PARIS, Jan 1 — Central Asia, the Sahel region and northern Europe experienced their hottest year on record in 2025, according to AFP analysis based on data from the European Copernicus programme.
Globally, the last 12 months are expected to be the third hottest ever recorded after 2024 and 2023, according to the provisional data, which will be confirmed by Copernicus in its annual report in early January.
But the average, which includes land and oceans, masks overall records for certain parts of the world.
Many poorer nations do not publish detailed climate data, so AFP has completed the global picture by independently analysing Copernicus data from climate models, measurements from about 20 satellites, and weather stations.
The data spans the whole world, hour by hour, since 1970.
Here is what the detailed analysis revealed for 2025, during which 120 monthly temperature records were broken in more than 70 countries.
Records shattered in C.Asia
Every country in Central Asia broke its annual temperature records.
Landlocked, mountainous Tajikistan, where only 41 per cent of the population has access to safe drinking water, saw the highest abnormal temperatures in the world, at more than 3C above its seasonal averages from 1981 to 2010.
Monthly temperature records have been broken every month since May, with the exception of November.
Neighbouring countries such as Kazakhstan, Iran and Uzbekistan experienced temperatures 2C to 3C above the seasonal average.
