I was meaning that tongue-in-cheek (like, I assume, the GP too) and you're right of course. In fact there were a series of short but unusually intense cold snaps in recent years in both the EU and US, which I think can also be traced back to climate change relatively easily: Global warming changes the way the polar jetstreams (aka polar vortices(?)) move, so the one in the northern hemisphere will more often stay to the south of populated areas and expose them to polar air and unusually cold weather. Then there is the other effect that warmer air captures more moisture and so warming can paradoxically lead to more draughts and more rainstorms.
