El Niño, 1998, And "Global Cooling" Revisited
July 29, 2009

To be honest, I've never been terribly interested in the long-running pseudo-debate over whether global warming "stopped" in 1998. If you don't know what I'm talking about, here's the dime version: 1998 was an exceptionally hot El Niño year, we're all agreed. Global temperatures have still been trending upward over the past decade, and the ten warmest years on record have all occurred since 1997, but it's quite true that there hasn't been a hotter year than 1998 yet. (OK, actually, if you use NASA's data, 2005 was the hottest year on record, but never mind.) But honestly, who cares?
