The Atlantic meridional overturning circulation (AMOC) is the main current system in the Atlantic Ocean, [1]: 2238 and is also part of the global thermohaline circulation, which connects the world's oceans with a single "conveyor belt" of continuous water exchange. [29] Normally, relatively warm, less-saline water stays on the ocean's surface ...
Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [ 1 ][ 2 ] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine the density of sea water.
Even if initiated in the near future, the circulation's collapse is unlikely to be complete until close to 2300, [89] Similarly, impacts such as the reduction in precipitation in the Southern Hemisphere, with a corresponding increase in the North, or a decline of fisheries in the Southern Ocean with a potential collapse of certain marine ...
A crucial system of ocean currents may already be on course to collapse with devastating implications for sea level rise global weather — leading temperatures to plunge dramatically in some ...
A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...
While climatologists say the collapse of the AMOC is a real threat, and that the new study raises a legitimate alarm that we may pass a key climate change tipping point sooner than previously ...
A Heinrich event is a natural phenomenon in which large groups of icebergs break off from the Laurentide ice sheet and traverse the Hudson Strait into the North Atlantic. [2] First described by marine geologist Hartmut Heinrich, [3] they occurred during five of the last seven glacial periods over the past 640,000 years. [4]
Scientists predict that the AMOC may come to a halt by the end of this century, with the possibility of collapsing even earlier, possibly within the next 20 to 25 years.
