In each state, we determined the average of each year’s average temperatures over the course of the 20th century. In no state is that figure lower than the 20th century average, nor has it been for at least a decade. (Philip Bump/The Washington Post)The state that’s seen the most modest change relative to its 20th century average is the usually-warmer state of Alabama. That’s the figure for Alabama in 2001, the last time that the 10-year rolling average for any state was at or below the state’s 20th century average. The trend is for states to see higher and higher temperatures relative to what they saw in the past century.
