This is the place for discussing the potential collapse of modern civilization and the environment.

Collapse, in this context, refers to the significant loss of an established level or complexity towards a much simpler state. It can occur differently within many areas, orderly or chaotically, and be willing or unwilling. It does not necessarily imply human extinction or a singular, global event. Although, the longer the duration, the more it resembles a ‘decline’ instead of collapse.

This factors in some feedback loops which most sudies to date have ignored. Note, that it excludes extra warming caused by all the additional water vapour in the air.

For context, studies suggest that the largest extinction event in Earth's history (so far), the Late Permian Extinction Event, saw temperature rises of around 8°C.

I hope this paper gets peer reviewed - I want to believe it so bad as I agree with the general ideas (people ignoring feedback loops and other factors which impact the climate as well). Though I do wonder sometimes if there are any remaining negative feedback loops which we aren't aware of, and might help as CO2 levels worsen. It certainly seems like we're already aware of all negative loops (the ocean, plant life, rocks?, etc), so we're really only missing the positive loops
