A 13-month streak of record-breaking global warmth has ended.
From June 2023 until June 2024, air and ocean surface water temperatures averaged a quarter of a degree Celsius higher than records set only a few years previously. Air temperatures in July 2024 were slightly cooler than the previous July (0.04°C, the narrowest of margins) according to the EU’s Copernicus Climate Change Service.
July 2023 was in turn 0.28°C warmer than the previous record-hot July in 2019, so the remarkable jump in temperature during the past year has yet to ease off completely. The warmest global air temperature recorded was in December 2023, at 1.78°C above the pre-industrial average temperature for December – and 0.31°C warmer than the previous record.
