Because of its huge economic and political implications, Climate Change is rarely presented without spin. This will be an attempt to do that. I'll discuss the physics of the greenhouse effect, and the data that indicate global warming. Among key topics are: Copenhagen -- why did we fail to get a major treaty? Climategate -- what really happened? IPCC standards -- and why they are undergoing major revisions. What are the top prospects among the many choices for alternative energy? What kind of example can the U.S. set that could be followed by the rest of the world? I'll also report on new results of our "Berkeley Earth" project -- a detailed re-analysis of the evidence for global warming; see www.BerkeleyEarth.org.
