Forget Copenhagen.

AAAAAAAARRRGH! AaaaaaAAAaaarrrrghgh!

Argh.

James - you ever consider what Peak Oil may do to the calculations? After all, if oil peaks in the next 5-10 years, it will take down the economy, and the "business as usual" scenario along with it.

Not exactly an ideal solution, but still...

Wohoo we might get warm summers up here in Sweden but if the gulf streem changes direction it will get very cold so its good if the temperature increases to compensate.

I highly doubt we will continue to use coal, oil at the increase per year we do now. Where will we get it from?
We ain't got that much coal and people hate coal mines.

Perhaps the huge cost of CO2 emission reduction should go to research in alternative energy sources instead. Or condoms so we don't get more people thereby less emissions and also a much happier humanity overall =).

Wait -- you mean that the process of political compromise that our species has developed over thousands of years can't be used to change the laws of physics? Madness.
