The official tallies are in and—huzzah!—2014 set a record for being the hottest year in known history. What was speculated a short while ago by Japan is now confirmed by both NOAA and NASA: most of the globe sweltered with abnormally high temperatures last year (though the eastern U.S. had a run on cold). Things are now roughly 1.4 degrees hotter than they were a century ago, and most of the warm-up has come since 1980.
