From Snowy Atlanta to Sunny Sochi, It’s All About Global Weirding

Why global warming sceptics have it wrong

The “If global warming is real, then why is it cold out?” line of argument has been around since the early days of the climate change debate, but the positively Hoth-esque temperatures have increased the volume of those hoping to undercut the “inconvenient truth” of anthropogenic global warming. So, does the recent spate of cold snaps prove Al Gore a filthy, PowerPoint-loving, Oscar-winning liar? No. Sorry, Donald.

Most obviously, climate is different than weather—that’s why the Midwest and Northeast have faced three snowstorms in the past two weeks while the drought in California has been so severe that water deliveries from reservoirs to the Central Valley have been cut to zero. Climate trends are exactly that: trends. One swallow doesn’t make a summer, and one blisteringly cold month doesn’t prove 97 percent of climate scientists wrong.

Another key component of “global warming” is right there in the name: “global.” In December 2013, North America was colder than average, but Russia and most of Europe were far hotter. Despite what Ted Cruz thinks (or wants), the world extends beyond the continental United States, and most of it has been crazy hot. For every cold snap in the U.S., there’s a wildfire in Australia so intense that it creates its own weather.

It’s also important to note that although, baby, it’s cold outside, it’s not nearly as cold as it was generations ago. The East River froze at least a dozen times between 1780 and 1888. In fact, after a particularly hard winter in 1866-1867, frustration with halted ferry service eventually led to the construction of the Brooklyn Bridge. As webcomic xkcd noted, St. Louis, once the frozen home to a handful of sub-zero temperatures every year, hasn’t had a day that cold since the 1990s. That’s the thing about extreme weather: It’s extreme. The colds get colder, the hots get hotter, and the hurricanes get more destructive.
