2025 was the third hottest on record and stood on the cusp of surpassing a major climate threshold globally, according to new data from Copernicus, the European climate agency.
The data indicates 2025 was about 1.47 degrees Celsius warmer than pre-industrial levels, following 2024’s record-setting 1.6 degrees. When 2023 is added to the mix, it’s the first three-year period on record to exceed 1.5 degrees, the data suggests.
