To me - it seems the existential fear around climate change is the topic of the day for environmentalists only because nuclear ended up not gaining traction. Nuclear waste/proliferation is not the number one existential threat these days only because it's used so little (both because of PR issues and lack of economics/long term maintenance challenges). The masses of environmentalists moved on from nuclear in the 80's but would surely return if nuclear regained traction.
