I know that many Americans like to think that the only things that matter happen in the U.S., but there’s a whole world out there, and while U.S. temps were cooler than normal in January, it was still warmer than normal globally.
The La Nina, which has an overall cooling effect, has contributed to global temperatures being not as much above normal during the past couple of months…and that trend might continue since La Nina’s global effects on temperatures are often delayed by a month or two.
See my AOL News article for more.
