LaClair said he was particularly upset about the book's treatment of global warming. The book says that "science doesn't know whether we are experiencing a dangerous level of global warming or how bad the greenhouse effect is, if it exists at all."
A newer edition published late last year was changed to say, "Science doesn't know how bad the greenhouse effect is," but the authors kept a phrase stating that global warming is "enmeshed in scientific uncertainty."
James Hansen, the director of NASA Goddard Institute for Space Studies, recently heard about La Clair's concerns and has lent him some support.
Hansen has sent Houghton Mifflin a letter stating that the book's discussion on global warming contained "a large number of clearly erroneous statements" that give students "the mistaken impression that the scientific evidence of global warming is doubtful and uncertain."
Polistra was named after the original townsite of Manhattan (the one in Kansas). When I was growing up in Manhattan, I spent a lot of time exploring by foot, bike, and car. I discovered the ruins of an old mill along Wildcat Creek, and decided (inaccurately) that it was the remains of the original site of Polistra. Accurate or not, I've always liked the name, with its echoes of Poland (an under-appreciated friend of freedom) and stars. ==== The title icon is explained here. ==== Switchover: This 2007 entry marks a sharp change in worldview from neocon to pure populist. ===== The long illustrated story of Polistra's Dream is a time-travel fable, attempting to answer the dangerous revision of New Deal history propagated by Amity Shlaes. The Dream has 8 episodes, linked in a chain from the first. This entry explains the Shlaes connection.
