The Earth has just experienced its warmest day in recent history, according to the Copernicus Climate Change Service (C3S) data. On 21 July 2024, the daily global average temperature reached a new record high* in the ERA5 dataset**, at 17.09°C, slightly exceeding the previous record of 17.08°C from 6 July 2023.
Based on preliminary data released by C3S on 23 July, Sunday 21 July was the hottest day since at least 1940, by a small margin of 0.01ºC.
While it is almost indistinguishable from the previous record, what really stands out is the difference between the temperatures since July 2023 and all previous years. The data can be explored in Climate Pulse, the C3S application that provides historical and near real-time temperature data from the ERA5 reanalysis dataset.
