The usual caveats apply: just a single number, more to understanding climate change than surface temp., etc. NASA’s GISS team has posted its global January number, with fodder for everyone to misinterpret. On one side, you could argue it’s cooling. (You’ve got to be careful in picking your starting year to make that case, but that does’t stop people from regularly doing it.) On the other side, you could argue that the five warmest Januaries in history globally have come in the last five years. Cherrypickers, have at it. Or you could just ignore the arguments and lay in a stockpile of salty snack foods in preparation for the winter Olympics.
Wait! Could we make a case that global warming threatens the winter Olympics?
