Global warming deniers: what went wrong with sticking your head out the window to prove it's colder than usual?

Last winter when we were having all the snows (which global climate change predicts, by the way) deniers were constantly talking about sticking their head out their window on a particularly cold day and thereby instantly analyzing climates around the entire world over the past 100 years. Apparently they have amazing heads.

But now that the central USA has seen 32 days over 100 degrees F. with tomorrow scheduled to be over 110 in Dallas, I am not hearing a word about the new-found climate science of sticking your head out a window. What’s wrong, deniers? Window air conditioner in the way? Heads melting and unablen to register such readings?
