Well, if precise scientific terms haven’t worked to dramatize the potential impact of climate change, perhaps imprecise, scary-sounding ones will. The U.K. government kicked off Tony Blair’s promised climate science conference today with a call to avoid “dangerous climate change.” All could agree it is to be avoided. Agreeing on a definition of “dangerous” is perhaps another matter.

This conference, held at the leading Hadley Centre for Climate Prediction and Research in Exeter, England, is part of the lead-up to Blair pushing climate change as he hosts the upcoming G8 summit. The U.S. government is a key target audience. When pushed to provide evidence of any budging in the U.S. position, U.K. Environment Secretary Margaret Beckett offered no examples, according to this BBC story.
