Right…those are the major concerns for warming of over 4C. That’s a realistic scenario if warming exceeds 4C (though more likely 6C…it just becomes a plausible reality around 4C). If we hit that level, collapse of civilization is on the table. Hitting that level also was realistic until the last couple years.

Warming 2.4-2.6C is really bad for a lot of people; it does not destroy and stress civilization to the point of widespread displacement and war.
