Is climate change humanity’s greatest-ever risk management failure?

Humans are generally very risk-averse. We buy insurance to protect our investments in homes and cars. For those of us who don’t have universal healthcare, most purchase health insurance. We don’t like taking the chance — however remote — that we could be left unprepared in the event that something bad happens to our homes, cars, or health.

Climate change seems to be a major exception to this rule. Managing the risks posed by climate change is not a high priority for the public as a whole, despite the fact that a climate catastrophe this century is a very real possibility, and that such an event would have adverse impacts on all of us.

For example, in my job as an environmental risk assessor, if a contaminated site poses a cancer risk to humans of more than 1-in-10,000 to 1-in-1 million, that added risk is deemed unacceptably high and must be reduced. This despite the fact that an American man has a nearly 1-in-2 chance of developing and 1-in-4 chance of dying from cancer (1-in-3 and 1-in-5 for an American woman, respectively).

To that 42 percent chance of an average American developing cancer in his or her lifetime, we’re unwilling to add another 0.001 percent. The reason is simple — we really, really don’t want cancer, and thus consider even a small added risk unacceptable.
