WASHINGTON (AP) — The United States is warming fastest at two of its corners, in the Northeast and the Southwest, an analysis of federal temperature records shows.

Northeastern states — led by Maine and Vermont — have gotten the hottest in the last 30 years in annual temperature, gaining 2.5 degrees on average. But Southwestern states have heated up the most in the hottest months: The average New Mexico summer is 3.4 degrees warmer now than in 1984; in Texas, the dog days are 2.8 degrees hotter.
