The collapse time is estimated between 2037-2064 (10-90% CI) with a mean of 2050 and the probability of an AMOC collapse before the year 2050 is estimated to be 59 +/- 17%.
We'll miss you, Gulf Stream.
TLDR: the Gulf Stream originates from a very different phenomenon than the AMOC and is not at risk of collapse. A small part of the heat transported by the Gulf Stream does originate from the AMOC though, but its collapse would be much less severe than a full collapse of the Gulf Stream.
