Shutting down the thermohaline circulation
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 … 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 27, 2015 · The Atlantic Conveyor Belt is a system of ocean currents that bring warm temperatures and important nutrients to the waters off of East Coast America and Western Europe. But as global warming melts ice in Greenland, the influx of fresh water seems to be slowing the northward drift down and could shut the system down altogether. WebOct 11, 2007 · The potential shutdown of the Thermohaline Circulation (THC), commonly misidentified (.pdf ) as the Gulf Stream, often makes the list of the most dangerous potential impacts of climate change. However, the current state of the science suggests 1) that the THC, rather than abruptly shutting down, is likely to slow over the course of centuries; and …

WebDec 19, 2013 · Thermohaline circulation, the large-scale movement of surface water through the world’s ocean basins, in latitudes near the poles is sensitive to temperature but even more so to salinity, so the larger concern in the North Atlantic Ocean comes from ice melt from the Greenland ice sheet and other sources of ice in the Arctic. The current melt rate … WebDec 14, 2004 · If global warming shuts down the thermohaline circulation in the North Atlantic Ocean, the result could be catastrophic climate change.
