The Center for Inquiry has found that the popular textbook American Government Institutions and Policies has such significant flaws in its coverage of the science of global warming that either a new edition should be published or a separate list of errors should be distributed.

Here is the story about a pretty cool Kansas high school student who first challenged the publisher:

Here is a link to the Center for Inquiry's assessment of the book:

To give you a flavor of their assessment of the textbook:

The discussion of global warming contained in Chapter 21 "Environmental Policy" suffers from egregious flaws and clear factual errors. The textbook wrongly portrays the settled, firmly-established science of global warming as a product of "activist scientists" and the source of "profound disagreement" within the scientific community.2 The textbook levels the outrageous charge that global warming "has resulted in a conflict among elites who often base their arguments as much on ideology as on facts." 3 Astonishingly, the textbook questions whether the greenhouse effect itself exists at all.
