Dim Bulbs

Jonathan Chait tires of George Will's climate change denialism:

Will (again) cites the unusually hot year of 1998 to prove that the planet isn't warming. He fails to understand a very basic concept in data that you don't need any particular social science expertise to grasp, which is that trends don't always move in a perfectly straight line. The planet has been getting warmer, and there was an extreme spike in 1998. Both these things can be true.
