In his new film, Merchants of Doubt, director Robert Kenner looks at a select group of charismatic pundits who spread confusion about threats ranging from toxic chemicals to climate change.
The men at the heart of Kenner's film have mobilized an army of climate deniers. Here are the three kinds you're bound to run into:
1) The Unchanged. This guy simply doesn't believe the climate is changing. Unfortunately, this brand of denialism has no basis in reality. 2014 was the hottest year ever recorded. The ten hottest years on record all came in the last 16 years.
2) The Unmanned. This denier acknowledges our climate is changing, but he doubts that humans are the cause. As James Inhofe, chair of the Senate Environment and Public Works Committee, once said, "The arrogance of people to think that we, human beings, would be able to change what [God] is doing in the climate is to me outrageous." As it turns out, us human beings are undeniably the problem.
3) The Unconcerned. Okay, the climate's changing and we're the problem, but what's a little warming between friends? This denier understands we're changing the climate, but he just isn't that bothered about it. This is the argument du jour of climate contrarians. Regrettably, there's plenty to worry about.
