2024 is the first year more than 1.5 degrees above pre-industrial levels

10 January 2025

On 10 January 2025 the European Copernicus Climate Change Service announced that 2024 had been the warmest calendar year in its records, with an average global temperature of 1.60 degrees Celsius above the pre-industrial level of 1850 to 1900, the first year to exceed the 1.5-degree threshold mentioned in the Paris Agreement. The heat was driven by greenhouse gas emissions, an El Nino event and other factors. This single year does not mean that the Paris target has been broken, since that is measured as a long-term average of about 20 years, but scientists say the world is likely to pass it in the coming decade without much faster cuts in emissions.
