You do know they where only making fun of the thing in general, the joke wasnt about global warming being real or not.. Right?
Yes, which is why I wrote the title the way I did (all inclusive). They were making fun of people thinking that the snow in DC or melting ice in the Arctic somehow scientifically proves/disproves global warming. It is a fair skewering of both sides beliefs.
So sick of snow, summer needs to get here already.

Good thing that CO2 only capacitates heat in the laboratory!
