In May 2025, the World Meteorological Organization and the U.K. Met Office released a new report. It stated that Earth will likely experience more years of very hot weather. This heat could cause serious problems. There is an 80% chance of a record-breaking hot year before 2030. In addition, there is an 86% chance that one year will go over 1.5°C above the old global temperature. This number was the target set in the 2015 Paris Agreement to avoid dangerous climate change. A 2°C rise is still possible before 2030, which would be very serious for many areas.

Experts said the extra heat may cause more heatwaves, heavy rainfall, long dry seasons, and large wildfires. Warmer air holds more moisture and energy, leading to more extreme weather events. The Arctic may heat up 3.5 times faster than other places. This will cause more ice to melt and raise sea levels. Scientists warned that this new heat may become normal. The forecast used 200 computer models from many research teams. The results are clear: strong action is needed for the future.
