9 Takeaways From the National Climate Report
A scientific report on climate change obtained by The New York Times, part of a regular federal climate assessment, shows that warming is already having a large effect on the United States.
1. It’s hot out there.
It is getting warmer everywhere, but in the contiguous United States, the West is warming the fastest. While temperatures in the country (excluding Alaska and Hawaii) have increased an average of 1.2 degrees Fahrenheit since 1900, the Southwest and the Northwest, as well as the Northern Great Plains, have seen a temperature increase of 1.5 degrees or more. A degree and a half may not seem like much, but even slight changes in temperature can have widespread effects.

4. When it rains, it pours more.
Americans are already experiencing more extreme precipitation. The amount of precipitation that falls in the heaviest storms is higher across the country, when storms from the last three decades are compared to storms from 1900 to 1960. The change has been highest in the Northeast, where 27 percent more rain falls in the worst storms.
