Feb 12, 2025 · Extreme precipitation is defined as precipitation equal to or greater than the top 1% of heavy precipitation events occurring between 1915 and 2018. These maps show the projected change in days with extreme precipitation under two average global warming scenarios: 1.5˚C (2.7˚F) on the left and 3˚C (5.4˚F) on the right.

How does climate change affect precipitation? Current climate models indicate that rising temperatures will intensify the Earth’s water cycle, increasing evaporation. Increased evaporation will result in more frequent and intense storms, but …
