Climate scientists just debunked deniers' favorite argument | Dana Nuccitelli

And in the process, illustrated the difference between skepticism and denial

Whenever they hold one of their frequent hearings to reject and deny established climate science, congressional Republicans invariably trot out contrarian scientist John Christy, who disputes the accuracy of climate models. In doing so, Christy uses a cherry-picked, error riddled chart, but there's a nugget of truth in his argument. Although the discrepancy isn't nearly as large as Christy's misleading chart suggests, atmospheric temperatures seem not to have warmed quite as fast since the turn of the century as climate model simulations anticipated they would.
