2024 is confirmed by the Copernicus Climate Change Service (C3S) to be the warmest year on record globally, and the first calendar year that the average global temperature exceeded 1.5°C above its pre-industrial level. C3S is implemented on behalf of the European Commission by the European Centre for Medium-Range Weather Forecasts (ECMWF), whose scientists have been monitoring key climate indicators, and documenting unprecedented daily, monthly, and annual temperature records over 2024. Human-induced climate change remains the primary driver of extreme air and sea surface temperatures; while other factors, such as the El Niño Southern Oscillation (ENSO), also contributed to the unusual temperatures observed during the year.
