I have been an admirer of Richard Muller for some time, though I had no idea that he was among the climate change skeptics. One of the reasons I admire him is that he follows the evidence, and in doing so, he came to a conclusion opposite to what his funders had hoped for: “that the Berkeley (Earth Surface Temperature) project would conclude that global warming is a myth.” No myth. No myth-take!
That quote is from Paul Krugman’s column in today’s New York Times.
To see how I treat this issue for young readers, read the climate modeling chapter in Seven Wonders of Exploration Technology (Twenty-First Century Books, 2010).
