The Atlantic meridional overturning circulation (AMOC) is a major tipping element in the climate system. Here, data-driven estimators for the time of tipping predict a potential AMOC collapse mid-century under the current emission scenario.
It doesn't stop overnight. In fact it has noticeably slowed down already. Of course the process becomes quicker when Greenland freshwater runoff becomes massive.
Yeah, I know it's a bit of a meme within the community. But surely scientists should start modelling in 'faster than expected' to get more accurate results.
