Nick,
Your optimism is refreshing and always backed up by some good links/facts or well reasoned arguments. Peak oil does not =peak energy!

I must admit to being pessimistic that CO2 levels will not be controlled until serious damage is done to ocean life by declines in pH and [CO3 =] ion.

Thanks for the compliment!

I agree about ocean acidification - that's a good example of why I'm less optimistic about climate change than I am about peak oil: ultimately, our FF consumption is under our control, while our effects on the planet are much less so due to lag times and positive feedback.
