WebJun 6, 2024 · If the thermohaline circulation shut down, cooling would likely occur only in regions that are currently warmed by the ocean conveyor. And even if the thermohaline circulation did shut down, winds would still likely drive the Gulf Stream; however, there would be less warm water from the tropics and the Gulf Stream could become cooler and not … WebDec 14, 2024 · Laura Jackson, the lead author of the study, stresses that it was an “idealized” model, using a large amount of fresh water to quickly shut down the Atlantic circulation and shorten the length ...

Shutdown of circulation pattern could be disastrous

WebJul 9, 2004 · Thermohaline circulation is driven by the sinking of cold, salty water at high latitudes. Fresh water flowing into the North Atlantic Ocean from rainfall or the melting of ice and permafrost can make the ocean water less salty, and therefore less dense. If it becomes "light" enough, it will not sink any more, possibly slowing or shutting down ... WebMar 13, 2024 · There are a number of ocean currents around the world and these currents are known collectively as a global ocean conveyor. One of the most significant driving forces in the circulation of the ocean waters is thermohaline circulation, where the density of water, affected by temperature and salinity, causes water to circulate. porsche gt2 cup car https://dlrice.com

WebReflections on a Possible Outcome of the Great Global Experiment. W. S. Broecker. Lamont-Doherty Earth Observatory, Palisades, NY 10964. ABSTRACT. Suggestions that the ongoing greenhouse buildup might induce a shutdown of the ocean's thermohaline circulation raise the questions as to how Earth's climate would change if such an event were to occur. WebThe global conveyor belt thermohaline circulation is driven primarily by the formation and sinking of deep water (from around 1500m to the Antarctic bottom water overlying the bottom of the ocean) in the Norwegian Sea. When the strength of the haline forcing increases due to excess precipitation, runoff, or ice melt the conveyor belt will weaken or …
