Reply #2: It's called wisdom.

Science tells us smoking causes cancer. Wise people can see further ahead to the cancer and don't smoke (or stop smoking.) Those who aren't very wise continue to smoke despite the scientific data.

Science is telling us all we need to know about climate. Now it's time for us to gain wisdom and act on that information. Figuring out how to change the mindset of 6 billion people is a very important area of academic inquiry.

If we don't pursue this area of inquiry, we're going to be the patient who stops smoking only after the first lung is removed.
