Climate Change Word Choice

There's a certain faction that insists that environmentalists ought to use the term "global warming" because Republican strategist Frank Luntz famously advised Republicans to say "climate change." In that light, I found it very interesting to catch this comment by "pimp hand strikes!" to a Matthew Yglesias post:

tut tut, yglesias. It is no longer 'global warming'. It is now 'climate change' since that allows us to cite any short term weather effects, whatever their nature, as proof of the coming apocolypse.

(I happen to prefer "climate change" not because of what the no-action side says, but because I think it's more accurate. But I also think quibbling over this one bit of terminology is a distraction from the larger question of proper and effective framing of the issue.)
