Global warming hit 1.37°C in 2025, with Earth accumulating heat at an accelerating rate
Key Points
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 Earth's 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 in Earth System Science Data.
