I intend to come back to this strip and rewrite some of the first half, in order to make the science clearer. I'm sure there will be a few spelling errors and suchlike. Feel free to point them out, but keep in mind that I've been staring at many of these pages for weeks, to the point where even the word 'and' looks funny to me. I shall be adding on references to this strip over the coming few days. Thanks to Albert the Knowledge Penguin for his help.
Note: added Jan 2012. A slightly different version of this strip will appear in my book Science Tales, out from Myriad Editions in April this year. This is a book of comic strip essays on controversial science subjects that include: chiropractic, evolution, the so-called Moon-landing hoax, the MMR/Andrew Wakefield vaxination scandal, and homeopathy. Read all about it here.
A few references. More will be posted shortly.
Superb New Yorker piece about the Koch Brothers and their involvement with the far right.
That Proceedings of the National Academy of Science paper, which I mention in the strip, on the numbers of climate researchers who believe that science points to the truth of man made climate change, compared to those researchers who don't.
Excellent book that does what it says on the tin. Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming, by Naomi Oreskes and Erik Conway.
NASA's climate change evidence page.
Wikipeadia entry on the the Fourth Assessment Report (AR4) of the United Nations Intergovernmental Panel on Climate Change (IPCC).
Scott Mandia's research into the media's deplorable Climategate coverage.
