"It's time to stop wrapping public policy around a fraud"

Daily Tech:
[A subgroup of physicists inside] [t]he American Physical Society, an organization representing nearly 50,000 physicists ... is now proclaiming that many of its members disbelieve in human-induced global warming. The [subgroup inside the APS] is also sponsoring public debate on the validity of global warming science. The leadership of the society had previously called the evidence for global warming “incontrovertible.” …

The [subgroup within the APS] is opening its debate with the publication of a paper by Lord Monckton of Brenchley, which concludes that climate sensitivity — the rate of temperature change a given amount of greenhouse gas will cause — has been grossly overstated by IPCC modeling. A low sensitivity implies additional atmospheric CO2 will have little effect on global climate.

Larry Gould, Professor of Physics at the University of Hartford and Chairman of the New England Section of the APS, called Monckton’s paper an “expose of the IPCC that details numerous exaggerations and “extensive errors”

Dr. David Evans, of the Australian Greenhouse Office:
When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty good: CO2 is a greenhouse gas, the old ice core data, no other suspects.

The evidence was not conclusive, but why wait until we were certain when it appeared we needed to act quickly? Soon government and the scientific community were working together and lots of science research jobs were created. We scientists had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet.

But since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming. As Lord Keynes famously said, “When the facts change, I change my mind. What do you do, sir?”
Ed Morrisey of Hot Air:
Even those who helped lead the hysteria now have serious doubts. It’s time to stop wrapping public policy around a fraud.
