We're still coming out of the last Ice Age...some are calling it Global Warming.
Actually, I'm in the camp that is firmly convinced that anthropogenic (man made) global warming is affecting our current climate... and that it's the only thing keeping the overdue ice age at bay!!!!
So throw another log on the fire!
Download the book Fallen Angels (free from Baen's library) by Larry Niven, Jerry Pournelle and Michael Flynn for a fun story based on that premise. They use the opportunity to skewer every liberal sacred cow they can. Fun book.
Seriously, I agree with your comment about still being in the "warm up" phase following the last ice age. It is well within the range of recorded evidence that we've got a lot more natural warming to go before things change, or that we're just about to tip over into another ice age. The most alarming thing to me about the so called science of "global warming" is the conceit of the money grubbing whores jockeying for grant money that somehow what they have known during their lifetimes is "normal" or "right." They simply don't have a clue about the nature of reality.
