These studies of potential "Tipping Points" are interesting, but the problem is they always are projections of effects that  "might" happen at some indeterminate time in the future.  This simply encourages inaction.  It's not happening NOW and you can't be sure if or when it will happen, so WTF are you supposed to do differently, other than the obvious prescription of stop burning FFs?  Which we all know won't happen, because there isn't enough alternative energy source available at the moment to feed 8B people parading around the planet.

This is why although climate is a long term existential issue, when I observe collapse the near term economic and political tipping points appear far more critical.  It seems unlikely to me BAU will continue on for another 15 or 50 or 70 years when these tipping points are supposed to kick in, and once we have full blown economic collapse people will be dieing like flies from that anyhow.  Political collapse will have them dieing from war.  So we can worry about dieing from climate collapse when we get there, after we finish counting the dead from economic and political collapse.
