Former White House regulatory czar Cass Sunstein says the international community hasn’t fought global warming because the people aren’t afraid enough.
“An understanding of what human beings fear — and what they do not — helps to explain why nations haven’t insisted on more significant emissions reductions,” writes  Sunstein, who is now a professor at Harvard Law School.
According to Sunstein, one reason people don’t fear global warming is because they don’t associate it with any “particular tragedy or disaster.” Even though environmentalists are quick to point to every weather event as global warming-induced, it’s hard to actually prove that warming caused the bad weather.
