The Copernicus Climate Change Service (C3S), implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the European Commission with funding from the EU, routinely publishes monthly climate bulletins reporting on the changes observed in global surface air and sea temperatures, sea ice cover and hydrological variables. All the reported findings are based on computer-generated analyses and according to ERA5 reanalysis dataset, using billions of measurements from satellites, ships, aircraft and weather stations around the world.

January 2024 was the warmest January on record globally, with an average ERA5 surface air temperature of 13.14°C, 0.70°C above the 1991-2020 average for January and 0.12°C above the temperature of the previous warmest January, in 2020.
