I heard -20C colder winters... ports getting fucked up due to ice... food production likely tanking.

Probably a lot of free variables in that problem. Press reports on climate modeling usually don't mention the gigantic error bars their predictions come with (especially for exotic long-horizon events like AMOC).

Also, -4°C was the average yearly temperature across the continent for a AMOC collapse. That doesn't contradict -20°C in winter in certain coastal regions (probably those most benefiting from Gulf stream heating right now) in the case of a full AMOC reversal.

But yeah, -20°C would be the end of agriculture. Let's hope for a worst case that is closer to... British Columbia.
