As we recently reported, on January 10, organizations involved in global climate monitoring, including the Copernicus Climate Change Service, NASA, NOAA, and WMO, officially announced that 2024 would be the hottest year since records began in 1850 and the first year on the calendar to observe warming above 1.5°C relative to pre-industrial levels.

The global average temperature is 15.10°C, 0.72°C above the 1991-2020 average and 0.12°C above the record for 2023, which was the hottest year to date. This is equivalent to 1.60°C above the estimated temperature in 1850-1900, which is considered to be the pre-industrial level.
