2025 ranked as the third warmest year ever recorded globally, according to data from the European Copernicus programme. Temperatures were just 0.01\u00b0C lower than in 2023 and 0.13\u00b0C cooler than 2024, which remains the warmest year on record. The past 11 years have also been the 11 warmest ever observed.<\/p>\n\n\n\n
A particularly alarming finding concerns the period 2023\u20132025: for the first time, a three-year average has exceeded the +1.5\u00b0C threshold compared to pre-industrial levels (1850\u20131900), the limit set by the Paris Agreement to avoid the most severe impacts of climate change.<\/p>\n\n\n\n
In 2025, the global average temperature reached +1.47\u00b0C above the pre-industrial level, following the record +1.60\u00b0C in 2024. Scientists estimate that long-term global warming is now around +1.4\u00b0C. If the current rate of warming continues, the +1.5\u00b0C limit could be permanently reached by the end of this decade\u2014more than a decade earlier than originally expected when the Paris Agreement was signed.<\/p>\n\n\n\n
Regionally, air temperatures over global land areas were the second highest on record. Antarctica experienced its warmest year ever, while the Arctic recorded its second warmest year.<\/p>\n\n\n\n
The data were released by the European Centre for Medium-Range Weather Forecasts (ECMWF), which runs the Copernicus Climate Change Service on behalf of the European Commission, in coordination with NASA, NOAA, the UK Met Office, Berkeley Earth and the World Meteorological Organization. Together, their observations confirm a clear trend: global warming is accelerating and pushing the planet ever closer to critical climate thresholds.<\/p>\n\n\n\n
