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.

I'm no climate scientist so I find this paper hard to interpret. Am I correct that they believe their early warning model indicates that the AMOC may be collapsing and if so, that Europe may face 3°C decreases per decade? And that that would essentially mean that large parts of europe would not be capable anymore to support populations of current size?

It's very speculative, but compare some places in Canada of similar latitudes in regards to population density and possibility to grow food to those in Europe. Very few people realize how atypically mild the European climate is relative to how far north most of it is.

So… I’m also not a climate scientist, but I also research dynamical systems within a time-based series (computer scientist). All of the research on this is very difficult to read, but it all sort of leads up to the fact that we are approaching some sort of tipping point where the system, in this case climate, will bifurcate. Meaning things will be different and can turn into chaos (chaos theory).

I’ve spoken with Dr. Edward Ott at University of Maryland on his work with climate change, and I’ve spoke with chaos theory researchers at University of Arizona. It’s all very abstract, and it’s difficult to predict what this actually means for the climate and for us.
