““Some of the scientists on Dr. Molina’s committee like to point out that people can be pretty intelligent about managing risk in their personal lives. It is unlikely that your house will burn down, yet you spend hundreds of dollars a year on insurance. When you drive to work in the morning, the odds are low that some careless driver will slam into you, but it is possible, so we have spent tens of billions of dollars putting seatbelts and air bags in our cars. The issue of how much to spend on lowering greenhouse gases is, in essence, a question about how much insurance we want to buy against worst-case outcomes.””
