In recent years this has played out largely as a contest between "global warming" and "climate change." Bush's use of the latter was consistent with Republican practice, which calls for de-emphasizing the urgency of the situation, as recommended in a 2002 memo by strategist Frank Luntz.
George Lakoff, the Berkeley professor of linguistics and cognitive science, is a strong backer of the dark horse "climate crisis," which is also favored by Gore (along with the rather more cumbersome term he used in his congressional testimony last month, "planetary emergency"). "'Climate change' doesn't suggest immediate action," says Lakoff. "'Climate crisis' says immediate action needed. The framing is not just a matter of labels, it's modes of thought. In Europe they use 'climate chaos'."
Richard C.J. Somerville, a leading researcher on"”um,
worldwide calorification?"”at Scripps Institution of Oceanography, thinks "global warming" is problematic because it puts the focus on worldwide average temperature, rather than the more serious regional dangers of storms, floods and drought. More pointedly, a leading Democratic strategist, Celinda Lake, actually endorsed "climate change" in 2004 on the grounds that "global warming" only works for half the year. "Every time we'd use the term in the winter, people would say, 'It doesn't feel that warm to me'," she said. (For the record, she now believes the issue has penetrated the public's awareness to the point where it doesn't matter much what it's called.)
