Team of Scientists Declare: ‘The Profiteers of Doom Were Wrong About Climate’
More than a century from now, on current trends, today’s concentration of CO2 in the air will have doubled. How much warming will that cause? The official prediction, 1.5-4.5 Celsius degrees per CO2 doubling, is proving a substantial exaggeration.
Professor William Happer of Princeton, one of the world’s foremost physicists, says computer models of climate rely on the assumption of the CO2’s direct warming effect that is about a factor two higher, owing to incorrect representation of the microphysical interactions of CO2 molecules with other infrared photons.
As if that were not bad enough, the official story is that feedbacks triggered by direct warming roughly triple it, causing not 1 but 3 degrees’ warming per CO2 doubling. Here, too, the official story is a significant exaggeration, as Professor Richard Lindzen of MIT, the world’s most knowledgeable climatologist, has demonstrated.
The wild exaggerations of both the direct CO2 warming and the supposedly more serious knock-on warming are rooted in an untruth: the falsehood that scientists know enough about how clouds form, how thunderstorms work, how air and ocean currents flow, how ice sheets behave, how soot in the air behaves.
In truth, we do not understand climate enough to make even an uneducated guess about how much global warming our adding CO2 to the air will cause. Other things being equal, we will cause some warming, but – on measurements to date – not much.
The national science academies and the UN’s climate panel have profitably contrived what the late Stephen Schneider called “scary scenarios” on the basis of inadequate knowledge.Etatiste politicians and bureaucrats have gone along with them.
