Angry in the Great White North

More lies from the IPCC.  This time, it's about hurricanes and floods:

THE world's leading climate change body was plunged into fresh controversy yesterday for wrongly linking global warming to an increase in hurricanes and floods.

The UN's Intergovernmental Panel on Climate Change based its claims on an unpublished and unverified report.

But it then ignored warnings from scientific advisers that the evidence supporting the link was too weak, it was claimed.

The report's own authors later withdrew the claim because they acknowledged that the evidence was not strong enough.

By the time [the paper on which the IPCC based its claim] was published in 2008 it carried a warning: "We find insufficient evidence to claim a statistical relationship between global temperature increase and catastrophe losses." Despite this change, the IPCC did not issue a clarification ahead of the Copenhagen summit.

Who cares about statistical evidence?  The only statistics the IPCC cares about are the ones tracking how much cash climatologists can scam from governments running scared at the thought of monster hurricanes ravaging their countries.

The IPCC went into Copenhagen knowing that the paper had backed away from the original claim, but they selectively ignored that correction.  Instead, in order to achieve their own political and financial goals, the IPCC repeated the earlier conclusion that the paper's authors themselves had refuted.

Oh, and by the way, the idea that a general uptick of temperature would cause stronger hurricanes doesn't even make sense.  If the effect of global warming is to make the planet as a whole more tropical, then hurricanes ought to decrease.  Look, it's not hard to understand.  Any system is driven by gradients.  Weather systems are the same.  High pressure and high temperature flows into low pressure and low temperature.  Put the flow on a spinning surface where the linear velocity at the surface decreases as you move north from the equator, and you induce a counter-clockwise spin (looking down from above) to the flow.  The rotation of the surface is constant, so the strength of the resulting vortex is constrained by the intensity of the flow, which in turn is defined by the steepness of the gradient.  If the temperature and pressure differences start to disappear as everything becomes more tropical, there is far less gradient and there far less intensity to the flow.  Ergo, less intense storms.

OK, where's my grant?
