The DUers are really torn over Michael Crichton's book, "State of Fear." Many of them clearly don't want you or anyone else to read the book. ("Once I put it down, I just couldn't pick it up!")
Others try to arm readers with information to counter Crichton's charges in the book. The counter-arguments are miserably lame and usually non-responsive to the charge. In other words, "we know we're wrong, so change the subject."
Still, others side with Crichton, declaring global warming--at least as caused by human activity--horsefeathers.
I'm with the last of these.
