True, but it means that you maybe shouldn't partake in extreme hysteria. I vividly remember my teacher in High School asking the students to raise their hands if they thought there would be a nuclear war with the USSR in their lifetime, and I was the only kid in my class who didn't think there would be. I imagine that there would be a similar response now, if you asked a bunch of kids if civilization was going to collapse due to global warming in their lifetime. Doesn't mean that global warming isn't a problem, just like nuclear war wasn't a problem; it just means that people have a hard time evaluating risk and likelihood.
