I really didn't want to say anything about George Will's recent Washington Post columns - RealClimate has links to the relevant discussions. I haven't read Will's columns for years, since before we canceled our Newsweek subscription. I had found his frequent clear misstatements annoying, and decided I was learning nothing from reading his opinions. So I've not made an exception in this case, I still haven't read what he actually wrote.
However, over at Andy Revkin's Dot Earth blog there have been several comments on the question of whether one or two (or 10) years of data can be considered strong evidence for a warming or cooling climate, and I thought I would add my own thoughts on that topic, somewhat relevant to the claims in Will's case.
