What is it going to take to bring clear thinking liberals to the side of reason on the matter of “human-caused global warming?”

It appears to me the greatest intellectual tragedy of our time that mankind has become so blinded about the question of “global warming” that the fact the Earth is not warming and that, if it were, human activity is a negligible factor in such “warming,” demonstrates that the popularly accredited cries for us to change the ways we do things are patently insane.

As Christopher Booker notes:

First, all over the world, temperatures have been dropping in a way wholly unpredicted by all those computer models which have been used as the main drivers of the scare…

Secondly, 2008 was the year when any pretence that there was a “scientific consensus” in favour of man-made global warming collapsed. At long last, as in the Manhattan Declaration last March, hundreds of proper scientists, including many of the world’s most eminent climate experts, have been rallying to pour scorn on that “consensus” which was only a politically engineered artefact, based on ever more blatantly manipulated data and computer models programmed to produce no more than convenient fictions.

Thirdly, as banks collapsed and the global economy plunged into its worst recession for decades, harsh reality at last began to break in on those self-deluding dreams which have for so long possessed almost every politician in the western world. As we saw in this month’s Poznan conference, when 10,000 politicians, officials and “environmentalists” gathered to plan next year’s “son of Kyoto” treaty in Copenhagen, panicking politicians are waking up to the fact that the world can no longer afford all those quixotic schemes for “combating climate change” with which they were so happy to indulge themselves in more comfortable times…

One of the more common arguments I have heard for blind faith in the dangers of “climate change” is something like Pascal’s wager: Believing in it, even if it be proven wrong, is less risky than denying it should it be proven right.

I think this is crazy talk, much as if someone told us we should stop going to work, “be prepared,” and instead dig holes under our houses because the world is about to end.

The evidence is against “global warming.” The idea that humans should alter their activity to potentially alter the temperature of the Earth because mankind’s survival depends on it is nonsense. What will it take to get us over this mass hysteria? Perhaps, the economy.
