Annual temperature (top) and precipitation (bottom) in the contiguous United States from 1895-2023 arranged from left to right. Each line shows a given year's temperature or precipitation compared to the 20th-century average. The darker the red or blue, the warmer or cooler the year. The darker the green or brown, the wetter or drier the year. Red bars dominate the right end of the temperature image, showing the influence of human-caused global warming on U.S. average temperature. The precipitation stripes image also shows a pattern of more green than brown in recent decades. Although there is a lot of variability from place to place, the U.S. average precipitation is increasing.
