[Editor note: David (P. D.) Henderson, formerly head of the Economics and Statistics Department of the OECD, is currently Chairman of the Academic Advisory Council of the London-based Global Warming Policy Foundation, which is headed by Nigel (Lord) Lawson). This is his first post at MasterResource.]

Over the past 22 years, governments everywhere and a great many outside observers have put their trust in the official expert advisory process as a whole and the IPCC process in particular.

I have come to believe that this widespread trust is unwarranted. But it is not just the IPCC process that is in question here. The basic problem of unwarranted trust goes further: it extends to the chronically biased treatment of climate change issues by responsible departments and agencies which the Panel reports to, and in nationally-based organizations which they finance.…

On June 10, the U.S. Senate will debate and vote on a resolution of disapproval (S.J.Res.26), sponsored by Republican Senator Lisa Murkowski of Alaska, to stop the U.S. Environmental Protection Agency from ‘enacting’ controversial global warming policies through the regulatory back door.

S.J.Res.26 would overturn the EPA’s endangerment finding, a December 2009 rulemaking in which the agency concluded that greenhouse gas emissions endanger public health and welfare. The endangerment finding is both trigger and precedent for sweeping policy changes Congress never approved. America could end up with a bundle of greenhouse gas regulations more costly and intrusive than any climate bill or treaty the Senate has declined to pass or ratify, yet without the people’s representatives ever voting on it.

At a minimum, as former Virginia Gov. George Allen and I explain elsewhere, unless stopped, the EPA will be in a position to determine the stringency of fuel economy standards for the auto industry, set climate policy for the nation, and even amend the Clean Air Act — powers never delegated to the agency by Congress.…

The wonderful “A billion here, a billion there, and pretty soon you’re talking real money” statement attributed to Senator Everett Dirksen  may be apocryphal, but it remains a prescient warning to our nation’s leaders. At a time when Congress is throwing billions of dollars around like pocket change based on claims of scientists and engineers, a real quote of Dirksen may be equally important (Congressional Record: June 16, 1965, p. 13884):

One time in the House of Representatives [a colleague] told me a story about a proposition that a teacher put to a boy. He said, ‘Johnny, a cat fell in a well 100 feet deep. Suppose that cat climbed up 1 foot and then fell back 2 feet. How long would it take the cat to get out of the well?

“[Robert] Mendelsohn’s position is rather similar to yours…. He believes the impacts are not negative at all for the US and most of the developed countries. Most impact studies seem to be showing this. It leads us to think that a little warming is not so bad. Glad I have kept my mouth shut on this issue of which I know so little.”

“I agree that the case for 2C warming [for a doubling of manmade greenhouse gas forcing in equilibrium] is pretty strong.”

Yesterday, the Wall Street Journal published my letter-to-the-editor rebutting Kerry Emanuel’s letter, which, in turn, was critical of his fellow MIT climatologist Richard Lindzen’s op-ed, “Climate Science in Denial.”…
