Short course in climate at An Open Mind

Tamino, who runs an excellent blog on climate and weather statistical analysis (most of it over my head mathematically :)) at An Open Mind (listed on the right of this page in the blog roll), has a lengthy response today to a lengthy comment on a post concerning the recent U.S. heat wave.  While his response is, as usual, very good, several of the comments are also very educational and provide a good short course on key indicators of climate change.  Recommended.
