What it doesn't need is Al Gore, which is kinda the subtext of the quotes from prominent academics and pundits in this USA Today piece by Dan Vergano, who elicits feedback on the recent Climate Reality event. This snippet caught my eye:
Gore trying to change public opinion over climate change puts the political cart in front of the horse, says sociologist Robert Brulle of Drexel University in Philadelphia. "People are busy, if Rush (Limbaugh) tells them it's crap, it probably is and that's good enough for them," he says. "All the research suggests that what really changes people's views are their opinion leaders saying something." The political divide between Republican and Democrats on environmental issues is simply a long-growing four-decade fact of American life, Brulle adds. "This is really all about political power." Until unexpected voices start venting different views, Brulle doesn't see climate politics changing.
So what "unexpected voices" would it take to move the arrow?
