The world’s sluggish response to climate change is a mystery to many. After all, overwhelming evidence of a problem usually results in mitigation of the problem. Witness the global response when scientists suggested in the 1990s that chlorofluorocarbons (CFCs) might be busting a hole in the ozone layer, leading to high rates of skin cancer, amongst other consequences. The reaction was swift; CFCs were banned from aerosol cans. In America, consumers voluntarily switched away from aerosol sprays, resulting in a 50% loss in sales even before legislation was enforced.
