Skeptics about the shrill certitudes concerning catastrophic manmade warming are skeptical because climate change is constant: From millennia before the Medieval Warm Period (800 to 1300), through the Little Ice Age (1500 to 1850), and for millennia hence, climate change is always a 100 percent certainty. Skeptics doubt that the scientists' models, which cannot explain the present, infallibly map the distant future.
The Financial Times' peculiar response to the CRU materials is: The scientific case for alarm about global warming "is growing more rather than less compelling." If so, then could anything make the case less compelling? A CRU e-mail says: "The fact is that we can't account for the lack of warming at the moment" -- this "moment" is in its second decade -- "and it is a travesty that we can't."
The travesty is the intellectual arrogance of the authors of climate change models partially based on the problematic practice of reconstructing long-term prior climate changes. On such models we are supposed to wager trillions of dollars -- and substantially diminished freedom.
Some climate scientists compound their delusions of intellectual adequacy with messiah complexes. They seem to suppose themselves a small clerisy entrusted with the most urgent truth ever discovered. On it, and hence on them, the planet's fate depends. So some of them consider it virtuous to embroider facts, exaggerate certitudes, suppress inconvenient data, and manipulate the peer review process to suppress scholarly dissent and, above all, to declare that the debate is over.
Consider the sociology of science, the push and pull of interests, incentives, appetites and passions. Governments' attempts to manipulate Earth's temperature now comprise one of the world's largest industries. Tens of billions of dollars are being dispensed, as by the U.S. Energy Department, which has suddenly become, in effect, a huge venture capital operation, speculating in green technologies. Political, commercial, academic and journalistic prestige and advancement can be contingent on not disrupting the (postulated) consensus that is propelling the gigantic and fabulously lucrative industry of combating global warming.
Copenhagen is the culmination of the post-Kyoto maneuvering by people determined to fix the world's climate by breaking the world's -- especially America's -- population to the saddle of ever-more-minute supervision by governments. But Copenhagen also is prologue for the 2010 climate change summit in Mexico City, which will be planet Earth's last chance, until the next one.
