It's Cold Out There.
It looks like the temporary and entirely natural warming cycle of the 90s is now completely over.
Of course they will talk about it until they find a new environmental boogie-man to hit us over the head with.
1960s Litter and DDT
1980s Acid Rain
1990s Hole in the Ozone Layer
2000s Global Warming (AKA Climate Change)
They'll "discover" a new doomsday threat. They always do.
