One of the blogs I've been struggling to get the time to read for quite some time now is Bob Tisdale's. This is Climate Audit territory - lots of graphs, lots of statistics, lots of reading to do before you can understand the full story. Like Climate Audit it's a site that cries out for an introductory text to enable newbies to catch up with the story that has gone before.
Fortunately, Bob Tisdale has now produced a book, which I'm currently working my way through. There are still lots of graphs and lots of statistics, but it's written in a good accessible fashion and I'm getting a great deal from it.
