Atlantic Circulation Is Showing Warning Signs And Scientists Have Modelled What Comes After Collapse
Scientists are finding growing signs that the Atlantic Meridional Overturning Circulation may be weakening, while new modelling reveals what could follow if the system eventually collapses. Researchers have identified changes in the Gulf Stream, the persistent cold region south of Greenland and possible instability within the wider circulation. Separate simulations suggest a shutdown could trigger severe Arctic cooling, major Antarctic warming and the release of deep-ocean carbon back into the atmosphere, turning an Atlantic circulation failure into a much wider planetary disruption.
