Spring Temperature Trends

By Climate Central

Spring has been getting steadily warmer almost everywhere. Nationwide, temperatures have climbed an average of 1.9°F since 1970 (0.42°F per decade). The greatest warming has been observed in southern Nevada, which falls in the West region, up as much as 6°F since 1970. The Southwest region has also experienced significant warming, up as much as 5.6°F since 1970.

Warming is not uniform. Temperatures have stayed nearly steady in a few places — parts of Montana, Oklahoma, Arkansas, New Hampshire, Vermont, Washington, Oregon, and the Dakotas. Small sections of North and South Dakota, along with a tiny sliver of Idaho, have gotten cooler, decreasing by as much as 0.42°F since 1970. But even with those few cooling spots, every climate region (as defined by NOAA) has warmed.

These local and regional differences illustrate a basic fact of climate science. Even as the world warms overall, some places will warm less than others.
