The Earth is accumulating heat at an accelerating rate. Global warming reached 1.37°C in 2025

Strong and consistent evidence shows that the entire climate system is continuing to heat, driving rapid global warming. Human activities pushed global warming to 1.37°C in 2025, and its level is projected to surpass 1.5°C in about four years. Crucially, the rate at which heat is accumulating in the Earth system suggests high levels of future warming. These are some of the key findings from the latest Indicators of Global Climate Change (IGCC) report, published recently in Earth System Science Data. An international team of more than 70 scientists, including…

2025 was the third hottest year on record

Copernicus data show that 2025 was the third warmest year on record [1], only marginally (0.01°C) cooler than 2023, and 0.13°C cooler than 2024 – the warmest year on record. The past 11 years have been the 11 warmest on record. Global temperatures from the past three years (2023-2025) averaged more than 1.5°C above the pre-industrial level (1850–1900). This marks the first time a three-year period has exceeded the 1.5°C limit. Air temperature over global land areas was second warmest, whilst the Antarctic saw its warmest annual temperature on record and…
