Is catastrophic global warming, like the Millennium Bug, a mistake?

Independent
"At a public meeting in the Commons, the climate scientist Professor Richard Lindzen of MIT made a number of declarations that unsettle the claim that global warming is backed by “settled science”. They’re not new, but some of them were new to me.....Lindzen says: “Claims that the earth has been warming, that there is a Greenhouse Effect, and that man’s activity have contributed to warming are trivially true but essentially meaningless.” ........How to explain the procession of eminent opinion leaders – some even in our own Royal Society – who advance the tenets of catastrophic global warming? “It is science in the service of politics,” he said.

If Lindzen is right, we will never be able to calculate the trillions that have been spent on the advice of “scientists in the service of politics”.
