And who is going to close the Bering Strait to make all that possible? There has been no collapse of the thermohaline circulation ever since sea-levels were higher than about 50m below current levels - the depth of the Bering Strait. https://www.pnas.org/doi/pdf/10.1073/pnas.1116014109
That doesn’t say AMOC can’t collapse - just that the AMOC off state isn’t stable without Beting being closed. You might be interested in this more recent paper, which has Hu as a co-author.
If there is no hysteresis it means that any cooling - such as through reduced thermohaline circulation - will result in warming through a strengthening of the thermohaline circulation without any meaningful delay. Thus: no collapse and no protracted cooling (as seen in NGRIP ice core data).
Yes, for a freshwater forcing of 420.000 cubic meters per second. That's 36.3 cubic kilometers per day or 13,245 cubic kilometers per year. That's a sea level rise of 3.7 meters per century or a complete melting of the Greenland ice-sheet within about 150 years.
This is a simulation of meltwater pulse 1A that lead to a collapse of the thermohaline circulation (THC), after 4-500 years of this rate of melting of the ice in Canada, Europe and Siberia. Except under present day conditions, with magic freshwater inflow.
Comments
After collapsing in the Open Bering State system it *return* in less than 400 years.
But it does collapse.
Ridiculous.
