If a doctor told you that your behaviours were courting death, you would stop your behaviour.

Probability here is irrelevant.

I think there are lots of people who have been given doctor's orders and refused to follow them.  Stop smoking, stop eating crap, get more exercise, etc.  The problem is always that the consequences are long term.  And somewhat vague.  Not all smokers die of lung cancer.

It's the same with climate change.  Vague consequences (to the individual), down the road a bit.

The main difference is in the likelyhood of action.  At least an individual might quit smoking.
