Wow. Just wow +Julian Bond 

What will the Climate Deniers make of that?

They'll grasp onto the quote “This is in principle good news, as ice ages are a great challenge,”. Which is the kind of thing people like Matt Ridley, Bjorn Lomborg, Piers Corbyn specialise in. Not denying climate change but denying that it's a problem. That's the next stage in denial.

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.

Indeed. And well said.

Thanks for the link to Hot Earth Dreams. I'm reading it with great interest now
