After a cold winter, some Americans have decided that climate change is a hoax

March was pretty cold this year, and you know what that means: Global warming is a hoax!

OK, that isn’t actually what it means. But for a depressingly significant number of Americans, the nippy weather was apparently reason enough to decide that climate change isn’t a real thing after all. Yale’s latest survey of public opinion on climate change found that the percentage of Americans who believe global warming is happening has dropped to 63 percent from 70 percent just last fall. This is the unfortunate corollary to the post I wrote last July, when tornados and scorching temperatures were driving belief in climate change to the highest levels since 2008.
