Fact or Fiction Friday

Welcome back to the latest installment of Fact or Fiction Friday. Get your face paint on, pull out your favorite team jersey, and let's get stuck in. But before we do, as always, check out this important disclaimer.

Alright, here we go. Fact or fiction: Global warming stopped in 1998. This is one of my favorites. It's almost as good as the argument that the world is cooling.

And the answer is . . . FICTION! At the time 1998 was the record holder for hottest year, due in large part to the strongest El Nino of the century. Choosing 1998 as your starting point on which to compare all the following years is a perfect example of cherry picking the data to suit your argument. But once you take a look at the trend lines you can see, despite the 1998 anomaly, global temperatures have been on the rise.

Head over to Grist's How to Talk to a Climate Skeptic or SkepticalScience to learn more about this issue, and other arguments often rolled out to refute the existence of global warming and resulting changes in climate.
