In 2024, the trend of record-breaking warmth continued, with January being the warmest on record according to the EU’s Copernicus Climate Change Service. This marks the eighth month in a row that has been the hottest on record for the time of year. The sea surface temperature is still at a record high.
The average monthly surface air temperature was 1.66°C higher than the estimated January average for 1850-1900, the designated pre-industrial reference period. This is according to the ERA5 dataset used by the Copernicus Climate Change Service (C3S), which is run by the European Center for Medium-Range Weather Forecasts on behalf of the European Commission. However, this does not mean that the world has exceeded the lower level goal of 1.5° Celsius above the pre-industrial era set out in the Paris Agreement on climate change. The Paris Agreement is about long-term warming over many years, not monthly or annual overshoot.
In January, global temperatures were 0.70°C above the 1991-2020 average and 0.12°C above
