Why not? These guys argue that the most rational solution is to get ready to deal with the problems, and stop worrying about the science behind “whether.”
If a global warming debate about certainty and cause only deepens doubt and defensiveness, what kind of debate would create support for action? We saw Hurricane Katrina as an opportunity to shift from the tired debate over cause and prevention to a new discussion about preparedness, thus reframing global warming from certainty to uncertainty and from limits on human activity to greater activity. Regardless of the cause, global warming is here and we need to prepare for it in the same way we prepare for any other imaginable natural disaster, not knowing exactly when or where it will strike. Global Warming Preparedness was created to test the possibility that action on global warming could be taken, not in spite of uncertainty, but because of it.

Are they right?
