For those who still don’t understand “what happened to global warming” when there were snowstorms in the Eastern US earlier this year … this graph explains very clearly that while it was indeed unusually cold in those parts, and in central Asia, large parts of the world that happen to be uninhabited by politicians, Fox News pundits and Exxon Mobil executives were actually unusually hot. The map is from the US National Oceans and Atmospheric Administrations, via Brian Collins’ superb “Interlinked Climate and Energy Challenges” website at Michigan State University.
It’s also important to understand that unusual snow storms are also a likely consequence of warming. You can’t have lots of snow without having lots of water vapour in the atmosphere. And it’s warming that puts it there.
