Because there are so many better reasons to scuttle the nonsense in Copenhagen:

While it’s great fun — and entirely worthwhile — to make a big stink about Climategate, it would be a shame if people believed that Copenhagen’s inevitable failure hinged on this one scandal. Even if the CRU researchers were the model of scientific dispassion, these schemes are pointless. Indeed, even if global warming is the threat the alarmists claim it is, it makes no sense to waste trillions of dollars on “fixes” that will do little to fix the alleged problem.

I like the reference to Canada as the Richie Cunningham of the UN.
