What shall we call it?

I recently learned that the term climate change came into common usage through Frank Luntz, a man who specializes in helping right-wing politicians (and cartels) tune their language to the emotional response they want or need (he also came up with "death tax"). Luntz's focus groups thought that climate change was less threatening than global warming; although, I don't think he did any of his research in Canada, where the idea of warmer winters isn't nearly as unpopular as he might've found it was in, say, Florida. Long-story-short, the Dubya administration started using climate change and now it has all but replaced global warming in mainstream media usage. (Aside: politicians lead most effectively through careful use of language).

Extreme weather events are becoming ever more commonplace, and this year both "red" and "blue" states in the U.S. have experienced them, though nothing gets attention quite like subway flooding in Lower Manhattan. Hurricane Sandy may turn out to be a turning point in climate politics, so it might be a good time to rethink how we describe the phenomena we are experiencing. As I alluded earlier, I think global warming isn't as threatening to Canadians as it might be to sub-Saharan Africans, Fijians, or even Frank Luntz's focus groups, but climate change is itself too clinical and antiseptic (probably what Luntz was going for, of course). Different regions are going to experience the effects of global warming differently (Europe may well get colder) with a few "winners" and a great many losers. For most people the felt issue isn't going to be an abstract degree or two of higher average temperatures world-wide, it's going to be the increasing unreliability of the seasons, and the weather; it will be the freak storms, droughts, wild-fires, and wild-life (water moccasins in Toronto?). So I'm proposing we ditch technician's climate change for a term both more accurate to real experience, and yes, more threatening: climate instability. Or perhaps, Anthropogenic Climate Instability; maybe Human-Induced Climate Instability?

Any other ideas?
