The U.S. Climate Change Science Program just relased the first of hopefully more "interpreted products" (meaning that it does not reflect policies, just the facts ma'am): Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences. Downloadable all in one swoop as an 180-page PDF; or, as individual sections and chapters. Notable features include a glossary and acronyms section so you can impress your friends with your knowledge of the technical side when you go see Al Gore's new movie.
