What we do now will stick around for 400,000 years. Flex your muscles, mankind. Doesn't that give you a sense of ... Power!

What will the Climate Deniers make of that?
I strongly recommend having a look at Hot Earth Dreams. There's a free 5 chapter sampler here.

This idea that blowing 1TtC of easily accessible carbon into the atmosphere in 100 years will take 400k years to leave again is one that's taking hold.
At the moment, I think it's all about the time-scales. If we move to a fully sustainable, small population over 200 years, it would be survivable, not particularly unpleasant and there'd be time for plenty of fun. There's a strong chance we'll be able to maintain an advanced technological society. If the systems force us to do it in under 50 years it will unimaginably horrific and post crash/burn, all bets are off.
I'll probably feel differently in a few months time.
