Stratospheric temperatures have been constant for 10 years

I read on http://www.realclimate.org/index.php/archives/2006/11/the-sky-is-falling/The long term trend in stratospheric temperatures is clearly downward. For the last decade, however,stratospheric tempratures haven't changed much.How can the stratosphere temperature be independent of the warming of the troposphere in the last ten years -why haven't stratospheric temperatures consistently changed over the last ten years?

Stratosphere is mainly warmed by absorption of UV from sunlight.

One of the prediction of GW is that stratosphere will cool, unlike-troposphere which will warm. IPCC http://www.grida.no/climate/ipcc_tar/wg1/351.htm" .

This is, however, no use for detecting climate change as it might be, because with decrease of ozone is predicted with decrease with temp.

Im not sure of the exact mechanism why it cools, etc. I don't think there is clear consensus.

Could heat from the stratosphere be warming the troposphere?

NO, stratosphere is stratified, there is little or no vertical motion of air masses. The radiative influence of stratosphre-troposphere is also not large.

Stratosphere cannot warm troposphere.
