Not at all.

It is a clear prediction of global warming that as more heat is trapped 
in the lower troposphere that the stratosphere at the heights where 
intercontinental aircraft cruise will get colder.

When it gets below -80C and the conditions are exactly right we get 
treated to displays of polar stratospheric clouds over the UK (which are 
normally exceedingly rare at temperate latitudes). There have been a few 
displays of PSCs in the past decade or so over the UK (prior to that you 
have to go back to Krakatoa in 1884-5 for regular annual displays).

The very cold air in the stratosphere is one consequence of less heat 
escaping from the troposphere and thinning of the ozone layer in spring.
