More Peer-Reviewed Studies Contradict Global Warming Alarmism

Published August 1, 2008

Despite what many global warming alarmists assert in the media, there are many articles in the world’s leading science publications contradicting the assertion that “the debate is over” about global warming. These articles destroy the illusion that there is a “consensus” among scientists about the causes of global warming. The following is the second of a three-part list of many such articles.
