We've been warming for about 15,000 years. It started way before anyone was
driving SUVs. We're really just in a warm spell in a 1.5+ million year old
Ice Age. It hasn't been warming long enough to say it's over.

There was a cool talk on this at Woods Hole recently by someone who's been
looking at oxygen isotope data in ice and sea cores. Pretty cool talk but I
wont butcher what the guy was saying by trying to parrot it back.  Basically
what I was able to pull out of it is that we have good records of global
temps going back pretty far but are at a severe loss to explain what causes
the various short and long term cycles.

I think the short term (5,000-10,000 year scale) has to do with snow
cover/cloud cover/albido issues and long term has something to do with
continental geometry but that's just a poorly educated hunch.  I am positive
that the really short term (5-10 year) fluctuations are solely due to bad
attitudes in the southern New England and Mid-Atlantic states.
