But its happening already right now, it will just become very much worse over the next three to six generations.. it is also clear what we would need to mitigate right now.. not doing it is robbing us of any future options. But I'm still wanting and waiting to here just one concrete option (which if not simpler nor cheaper than preventing further greenhouse gas emissions I'm not sure why we would want to do those then at all) that could help the e.g. surely unavoidable famine problem that we will encounter if world cements its path towards 3-4°C? There is just none even imaginable.. > Or continued serious drought, or climate migration, or massive heat die-offs, etc. We know these all will happen together?
