Most U.S. states are warming but not in the way you think

Why it matters: Uneven warming across U.S. states impacts regional ecosystems and infrastructure differently.
- About half of U.S. states are experiencing rising average temperatures, a figure that masks more specific warming trends across the nation.
- Most states are heating up through particular shifts, such as hotter high temperatures or warmer low temperatures, rather than a uniform increase in average temperature.
- Regional variations in warming are significant, with the West experiencing more extreme heat, while the North shows different specific warming patterns.
While only half of U.S. states show an increase in average temperatures, most are experiencing significant warming trends through hotter highs or warmer lows, indicating a more nuanced and uneven climate shift than initially perceived. These regional variations include the West facing more extreme heat and the North experiencing different specific warming patterns.
