The Atlantic Meridional Overturning Current, of which the Gulf Stream is a part, may collapse by the middle of the century or possibly as early as 2025, according to a new study published on July 25, 2023in the journal Nature.
The AMOC would deteriorate during the course of this century, according to a 2019 research by the UN's Intergovernmental Panel on Climate Change, although its complete collapse before 2100 seemed unlikely. According to Ditlevsen, this area of the ocean is warmed by water that the AMOC carries north from the tropics; as a result, if it cools, the AMOC is losing strength. In order to understand how the currents were changing, the authors then subtracted the effects of human-caused global warming on the water temperature.
