Using examples from the history of science Dr. James Powell explains why it is unlikely that climate scientists are wrong about global warming. However his final consideration is probably the most apropos in the current debate over climate change: the possibility “that scientists are deliberately wrong, engaged in a global conspiracy,” and concludes that “this notion, [is] the intellectual equivalent of believing that the Earth is flat or that men did not land on the Moon. To claim conspiracy is to prefer a blatant absurdity over scientific fact and only because accepting global warming does not happen to suit people. But the implacable laws of science remain unaffected by what suits us.”
