Cooling global warming hysteria just one story of '08

As James Peden, an atmospheric physicist, said, many scientists "are now searching for a way to back out quietly" from global-warming fearmongering, "without having their professional careers ruined."

This is an ethical or political problem, not a problem in climate science. The crux of it is that major research grants and, in this country, prestigious Canada Research Chairs, have been awarded on the assumption something must be done to stop CO2 from destroying the world.

Those scientists who are the current beneficiaries of a moral panic they help sustain are squirming not because of their ethical transgressions but because of scientific facts. Facts are fragile because they could always be different, but stubborn because they are what they are, independent of opinions, including any "consensus." In this context the big inconvenient fact is that for almost a decade, ice-core data have shown climate cycles antedate changes in atmospheric CO2.

In 2006, experiments at the Danish National Space Center provided evidence that changes in the magnetic field of the sun can affect not CO2 but water vapour--clouds--which are responsible for up to 95 per cent of the warmth that keeps Earth habitable. Last year the implications finally sunk in.

The original experiment is being replicated by CERN, the European Organization for Nu-clear Research, so stay tuned.

Remember, there is no experimental evidence--none at all--that an increase in CO2 can increase greenhouse warming, and that ice-core evidence indicates the causal arrow does not go from changes in CO2 to changes in climate...
