“Scientists” have been warning the world about this since Stommel issued his paper in 1961:

It’s going to shut down
The ice caps and antartic ice are going to melt entirely
The Gulf Stream is going to collapse
Global emissions have skyrocketed with no brakes since then
1.5C target was a joke. 2.0 target is a joke. There is no world where humans can coordinate in a way that reduces global emissions
MAYBE by accident with enough selfishness around not wanting to die. I don’t see it though
> There is no world where humans can coordinate in a way that reduces global emissions
They seem to have cooperated rather effectively on increasing them, so I wouldn't say "no world"?
The archeological and geological records strongly suggest we've been down this road before. There's as much arrogance in assuming we can prevent this, as there is in assuming we caused it (perhaps hastened it). Best use of national or global resources is preparing for the outcome, not trying to prevent it.
The problem is that by the time it becomes incontestable that the scientists were right, it will be much, much too late to do anything about it.
