Precipitation varies significantly across the U.S. Late summer and autumn tropical cyclones bring rain, dropping across the Atlantic states and Gulf area. In winter and spring, Pacific storm systems get Hawaii and the western U.S. states most precipitation. Low-pressure moving up the U.S.’s eastern shore brings cold season precipitation to the Mid-West and Northeast U.S. states.

How is climate will change in the U.S. (2030 – 2100)?

Since 1901, the average temperature across the contiguous U.S. states has grown at an average rate of 0.16°F (0.09°С) per decade. Average temperatures have grown more rapidly since the late 1970s (0.31 to 0.54°F or 0.17°С to 0.3°С per decade since 1979). Eight of the top ten hottest years on record for the contiguous U.S. states have happened since 1998, and 2012 and 2016 were the 2 warmest years on record. Over the following few decades (2021–2050), yearly average temperatures are supposed to grow by around 2.5°F (1.39°С) for the U.S., related to the recent past (average from 1976 – 2005), under all probable future climate scenarios.
