The description of the book doesn't make me want to read it. His
argument is that all "deniers" are funded by powerful interests or
simply naively helping those powerful interests.
I wonder if he actually addresses the short-comings of his methods in
the book.
The trouble with the hockey stick is that both the historic and
modern temperatures are not consistent with most other data
available in the peer-reviewed literature (for historic data) and for
satellite data for global temperatures (available since 1979).
For
example, the midieval warming period seems to be absent from the
data. A literature review finds 200 peer-reviewed articles that
discuss the MWP by 660 different scientists from 385 separate
institutions. Of those, 66 articles give quantitative data: 56
indicate MWP temeratures greater than today, 8 equalling today's
temps, and only 2 indicating less than today's temperatures (this is
consistent with Mann's work).
They also failed to explain why in their methods that they included
a weighting scheme that heavily weighted tree ring data that showed
a substantial warming trend over data that did not.
