They start with an ad hominem and their arguments deteriorate from there by just making shit up.
Contrarians Using Hacked E-mails To Try to Fool Public on Climate Science
In their ongoing campaign to distort the facts and deceive the public, climate policy opponents are misrepresenting illegally obtained e-mails from the Climate Research Unit at the University of East Anglia in Great Britain. Opposition groups are taking passages out of context to try to undermine public confidence in climate science.
The e-mails provide no information that would affect the scientific understanding of climate change, as many contrarians are falsely claiming. For years, thousands of scientists working at climate research centers around the world have carefully and rigorously reached a consensus on the extent of climate change, the urgency of the problem, and the role human activity plays in causing it.
UCS should try looking at the computer code that was also released by this courageous whistleblower. If it is beyond the abilities of these Concerned Scientists, Lord Monckton has conveniently issued a report that addresses the manipulation of data in the CRU codes.
Who are the deniers, now?
