David Holmgren, co-originator of the permaculture concept, has a website that features speculation on the future of civilisation vis-a-vis peak oil and climate change.
http://www.futurescenarios.org/
I believe he is doing some of the best thinking in terms of what will come to be, as the twin influences of peak oil and climate change effect us.
He has also recently struck a deal to develop this web site into a book form next year, so keep a look out for that.
I would recommend in particular, that people read about his 4 energy decent scenarios. The essay can be found
here.
Brown Tech: (slow oil decline, fast climate change)
Green Tech: (slow oil decline, slow climate change)
Earth Steward: (fast oil decline, slow climate change)
Lifeboats: (fast oil decline , fast climate change)
Currently, the state we're in most accurately resembles 'brown tech'. Doomers will find the 'lifeboat' scenario their favorite.

remove that video. It is very annoying to include an auto-play video in a text thread.
