Well of course it is inconsistent with you mjp.

The ipcc reports vary from TAR, AR4 and AR5. Mostly AR4 and AR5


From observations confirming the poleward advance to the IPCC being clear that a cooling stratosphere causes the circumpolar jets, westerly jets or another common name in the Polar Vortex to tighten.

I have posted that the IPCC also state that like ghg's ozone loss also also contributes to a contraction of the polar vortex.

You can go on a fish hunt if you want to looking up every nook and cranny for a way out of this. But for what I have posted it is clear.

How one could construe anything less would have to be plain mischievous.


you need to address the common theme and that is a cooling stratosphere is responsible for a poleward shift in the polar vortex.
