Environmental alarmists will scream about forest fires ignoring the fact that I know what I am doing. They scream about super hurricanes, then when we don't have any, they look stupid. If anything, they hurt your cause since the average joe will tune everyone out, alarmist or not.
Science isn't a democratic process though.
I know the IDer's wish it were so, but it isn't. Scientists need to base their recommendations on the best available science. Politicians heed or ignore their advice at their own peril.
At the moment I see every industrialized nation with leaders that more or less except what the overwhelming majority of the scientific community is telling them about man's contribution to climate change. The only exception is the American President. The same statement could be made about evolution.
