Another thing Holdren said answered a question I'd been wondering about for a while -- why have the cool kids stopped using the term "global warming." Holdren said this phrase wrongly implies to people a uniform change and that, in turn, makes talk of a single-digit change in temperatures sound like no big deal. After all, lots of places experience a seven degree temperature swing in a single day. The point that needs to be gotten across is that the temperature change will produce all kinds of large, but somewhat localized changes as climate patterns shift about. He likes the phrase "global climactic disruption" though I think we'll probably have to stick with "climate change."
