My point is that if we do nothing about climate change it will still inevitably cause the same if not more devastation than that of nuclear and bioweapons. One is absolute if we do nothing, the other is not so obvious. At the end of the day there isn't ever one focus, there are multiple focuses when it comes to keeping ourselves and each other alive. The risks of climate change IMO are not a question of how but when, in amongst all other health risks.
