Since Americans first heard the term global warming in the 1970s, the weather has actually improved for most people living in the U.S. But it won't always be that way, according to a new study.

Research shows Americans typically — and perhaps unsurprisingly — like warmer winters and dislike hot, humid summers. And they reveal their weather preferences by moving to areas with conditions they like best.

A new study in the journal Nature has found that 80% of the U.S. population lives in counties experiencing more pleasant weather than they did 40 years ago.

“Virtually all Americans are now experiencing the much milder winters that they typically prefer, and these mild winters have not been offset by markedly more uncomfortable summers or other negative changes,” write Patrick Egan, a political scientist at New York University, and Megan Mullin, professor of environmental politics at Duke University.

It’s hard to complain about sunny days, but the researchers foresee a problem. If Americans think climate change has benefited their lives so far, they’ll have little motivation to demand action or overcome apathy in responding to global warming, the scientists write.

By the end of the century, however, the study predicts the pleasant weather trend to reverse as summers heat up to uncomfortable temperatures.
