Not much chance for change.

Have a look at the thousands of comments on Copenhagen COP 15 and climate change on this moderated  BBC discussion forum.  Especially if you’re a green thinker.  It’s pretty depressing, though no surprise.  The reds are loud and cynical, the greens are modest.  And it seems that there are far more reds.  Which means rich people (ie everyone writing their comments on a computer, not the poorest 3 billion) are not willing to change their behaviour, because they see no reason to do so.
