'Global cooling' is one of the most pervasive myths put forward by those bent on sowing doubt and confusion about climate change. It goes like this: Ever since 1998, a year when record-high global temperatures were recorded, the world has been undergoing a gradual global cooling.
Of course, that's simply not the case. Average temperatures have been steadily rising, as climate scientists have predicted. But don't take my word for it. Here's a video of leading climatologist Ben Santer debunking the myth, and explaining how it illuminates an important principle of climate science in the process.

If you're of a wonkier persuasion, you may recognize Santer from his appearances at Congressional hearings, where he routinely offers robust and vigorous defenses of the evidence in support of global climate change.
