What about the physical and psychological damage if the scientists are right and things get really really really really bad? If the ocean levels really do rise 10+ meters, won’t that cause even worse psychological damage? If places like the Middle East really do become uninhabitable, won’t that cause even worse psychological damage? Millions of refugees. If the vast majority of sea life dies, won’t that cause psychological damage? What about the Atlantic current stopping and the effects that would have on Europe? What about the increased drought and crop failure? What about invasive species moving farther North? More animals going extinct? Etc. It seems to me that the psychological damage from any and all of those will be far worse that what you are worried about.
