There's a good opinion piece in The Tyee by Michael McGonigle, in which he argues that Copenhagen must fail "if we are to win the fight against global warming".
Looks like he might get his wish, although there's still a chance that his worst fear might be realised: a weak climate change agreement that acts like a major obstacle to change. I haven't heard that many advocates making the connection between climate change and the general ill health of the environment, although it's pretty plain to see.
