I actually think there is more evidence that we are headed into a period of climate cooling, maybe long term. We are clearly in a interglacial period. The question is how long is the period ? Of course you could state that the last Ice Age was the last ice age and will never happen again! of course one must forget the earths history which shows a repetition of ice ages. Maybe there won't be another Ice Age because we have the shining genius of liberal thought stopping all these previously unstoppable geophysical, solar, galactic & intergalactic forces that give us climate. Yeah right!
Anyway I in 400 years we may find ourselves wishing for global warming ! Solution: SUV’s needing tune ups for all!
I actually think there is more evidence that we are headed into a period of climate cooling, maybe long term. We are clearly in a interglacial period. I think it's moot if the Mayans are right. So let's wait until 2013 or whenever the next near-term prediction of universal doom is supposed to occur before we implement anything (there's always a new one waiting in the wings when the last one didn't happen, anyway).
That said (in fun), The 'buzz' was about the coming Ice Age in the '70s, then global warming by the '90s, and now we're cooling again. 30 year cycle anyone?
