Bob Tisdale's illusion is that global warming is caused by magic, or blobs, or El Niño. Anything but human activity. He's announced at WUWT that he has written a new book (archived here). He's called it "On Global Warming and the Illusion of Control Part 1". It's very long, running to 733 pages. You'll have to wade through 82 pages before you get to the first page of the first chapter. There are three chapters plus the 82 pages of introductory material.
Bob relies on the hard work done by climate scientists for much of his book, he picks bits he likes but ignores or rejects the bits he doesn't like. That is, he rejects all the science that confirms human-caused warming. For the most part, he doesn't understand the data he uses. Certainly he doesn't understand climate models. For the other much of his book, he relies on conspiracy theories dreamt up by him or other science deniers. What his book boils down to is:
- Climate scientists are right, except when their science demonstrates that humans are causing global warming, and except when he can provide an alternative notion, usually involving a gigantic conspiracy of incredible proportions, or no alternative at all
- Bob learnt lots about ENSO from Dr Kevin Trenberth, but doesn't believe him where it matters
- According to Bob, the cause of global warming is hotter oceans (i.e. warming is caused by warming), or a magical bounce from the Little Ice Age with no cause, or the sun heating up the ocean (even though the sun's output has decreased a bit lately), or anything except human activity
- Climate models are wrong - based on Bob not understanding the first thing about them
- The IPCC is [insert conspiracy theory here] - based on Bob's denialist imagination.
