Ars Technica has a neat piece on the current pseudo-controversy in the field of global warming cooling warming.

The facts are that 2008 was cooler than the last few years, but warmer than most in recent history, which lends itself to spin based on the predilections of the person talking about it. But some of that spin specifically plays upon the widespread innumeracy of the public, which isn't well prepared to separate trends from short-term variability, or recognize when certain figures are selectively chosen. We'll try to separate out some of these in a way that will hopefully help readers make a bit of sense out of the conflicting noise.
