We can perhaps look at current trends and extrapolate. Currently at less then 1.5° C and we are seeing a lot of failed policies both regarding minimizing further warming, and dealing with the current damage. We are seeing many people dying in various climate related disasters (by some estimate covid level numbers and growing). We are seeing crop failures, a mass extinction event, we are seeing pests becoming more severe, both in the natural world (see the giant Sequoias in Yosamite) as well as in our crops. This will get worse. Note, we will probably have enough food, but just like now, it will not be evenly distributed. Expect famines in the future. Currently things are not so bad. We are seeing a lot of people fleeing their homes, and we are not seeing anybody accepting them as refugees. As the climate warms further, one can expect either our refugee policy changes and we open our borders (unlikely) or we can expect wars to break out as migration crises become severe (likely). As the global hunger increases, as global wealth distribution gets worse, and as the global poor are at serious risk of dying from climate disasters, famin, etc. As tension grows on our borders, and as our governments become increasingly hostile towards refugees, then I honestly don’t see how our democratic world can survive. Of course our governments can make the right choice and open our borders, then it will be a different world, that still sucks from all our climate related disasters, but at least it might survive. The other option is a increasingly facistical world. Which in my book is definitely civilization crushing.
