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.

Is the Atlantic Overturning Circulation Approaching a Tipping Point? (tos.org)

The Atlantic Meridional Overturning Circulation has a major impact on climate, not just in the northern Atlantic but globally. Paleoclimatic data show it has been unstable in the past, leading to some of the most dramatic and abrupt climate shifts known. These instabilities are due to two different types of tipping points, one linked to amplifying feedbacks in the large-scale salt transport and the other in the convective mixing that drives the flow. These tipping points present a major risk of abrupt ocean circulation and climate shifts as we push our planet further out of the stable Holocene climate into uncharted waters.

Intetesting, any study to back those numbers?

just going chime in here with an unsourced figure.

quite some time ago I read a few articles claiming a comfortable global carrying capacity of about 500 milion for a post fossil fuel world. this number is old (as I am), and I have no idea if this was misinfo/disinfo/propaganda but if you poke around you may find more detail.
