Ok, so for those who do not believe that the globe is warming, take a chill pill and engage An illustrated guide to the latest climate science « Climate Progress.
I am not a fan of Thomas Friedman, but he makes a good point on the subject of “global weirding,” at the New York Times.
And, for those of who still doubt the science and its process, see the “Discovery of Global Warming,” which is an excellent (and overly detailed) primer on the science behind our understanding of this change.
You can even find a teacher’s guide on the subject.
