If you have a (virtually) unlimited amount of time and energy to expend on thinking about climate change and its impacts, go for it.

My point is that you will get far more bang for your buck if you spend energy on political action. Most ordinary people don't have time to spend on HN arguing about the best way of stopping climate change, they have other things to do in their lives -- and we should be convincing them to take political action (with us) instead of wasting their limited amounts of spare energy on minor personal changes that won't have as much of an impact.
