Forget "deniers"
Forget "skeptics"
Lets "frame" them as Procrastinators.
Years ago, we had a chance for relatively inexpensive and gradual fixes to a wide range of environmental problems. But instead, we procrastinated until the problems seem so pressing that we suddenly have to do something. Now, of course, like the high school student who has wasted the days away and has to do a term paper overnight, we're desperate for a solution. The quick fixes that seem most available at this late stage will be very expensive. And, since decisions made under pressure often turn out to be bad decisions, they may not even work.
Jim: there are still a bunch of "procrastinators" out there...
