In doing so, it sinks to the ocean bed and pushes the deep segment of the conveyor belt forward.

For decades, research on climate variations in the Atlantic has focused almost exclusively on the role of ocean circulation as the main driver, specifically the Atlantic Meridional Overturning Circulation, which carries warm water north in the upper layers of the ocean and cold water south in lower layers like a large conveyor belt.

Gentlepeople, well done on nipping any controversy in the bud — as usual; though I'm left wondering if the warming trend isn't related to a subject that i'd like to see Real Climate Address more often; The possible shut - down of The North Atlantic Conveyor — as extreme warming of the Southern Oceans, along with the plunging of Europe into a new Ice Age would be the result of this, as I'm sure you all know.

The ocean conveyor gets its «start» in the Norwegian Sea, where warm water from the Gulf Stream heats the atmosphere in the cold northern latitudes.

I have to raise an objection to the phrase «the only region of the world that has defied global warming» — that might be neglecting a certain area in the Pacific where England 2014 has identified a very obvious point where the «Pacific conveyor» was bringing in the last decade up a lot of cold water from the deep ocean and has possibly played a major role in the specific trends for that period.

I haven't had time to read all of these postings — let alone Jim Hansens DIRE piece (though I DID just download it and I will do so; and Thank You, by the way, for telling the WHOLE SCARY Truth Dr. Hansen); but, out of what I did scan, I didn't seem to notice any references having been made in regards to the possibility that the Fresh Meltwater comming off of the Greenland Ice Sheets — and them plunging striaght to the bottom of the North Atlantic Ocean — could shut down the so - called «Atlantic Conveyor».

For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to heat & drought & wild fires enhanced by GW (reducing or cutting short their uptake of CO2 & releasing CO2 in the process) 3) ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more heat 6) the warming slowing the thermohaline ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.

Half of that CO2 is removed from the atmosphere by rain in the Arctic and buried deep in the ocean by the descending leg of the THC (the Conveyor ocean current.)

It releases more than it absorbs because of ocean conveyor belt circulation pulling in tropically warmed water.

The sink in the Greenland Sea is simply part of a vast conveyor belt that carries the North Atlantic's excess salt to the less salty southern oceans and eventually to the Pacific Ocean.

Losing the perennial Arctic sea ice is speeding up the melting and partial disintegration of the great Greenland Ice Sheet, and is also having an effect in Antarctica, partly through disruption of the «great ocean conveyor» which sends Arctic - cooled water all the way to the Antarctic.

During his study, Wallace Broecker discovered that the currents in the Atlantic Ocean sort of work like a conveyor belt, bringing warm water up from the equator and sending cold water down to the equator.

Broecker had already distinguished himself in his work on what's called the «ocean conveyor belt» — the system of jet streams and other circulatory patterns that stir the planet's waters, regulating heat along the way.

Nothing like this happens in the Pacific Ocean (which is, in consequence, about 5 °C cooler), but the Pacific is nonetheless affected, because the sink in the Nordic Seas is part of a vast worldwide salt - conveyor belt.

Currents that move through the upper ocean then dive down to depth may move some of the surface heat to the deeper waters, especially where the currents have dived not just from cooling water (hot water would tend to go up, cold water would tend to go down) but because it is driven in «conveyor» systems which may run counter to expectations of where water should go when considering only local conditions, and especially, if the water is dropping because of an increase in salinity.

In the Atlantic Ocean, the Gulf Stream is part of what's called the Atlantic Meridional Overturning Circulation, a conveyor belt of ocean water that carries warm water from Florida to Greenland where it cools and sinks to 1000 meters or more before traveling back down the coast to the troOcean, the Gulf Stream is part of what's called the Atlantic Meridional Overturning Circulation, a conveyor belt of ocean water that carries warm water from Florida to Greenland where it cools and sinks to 1000 meters or more before traveling back down the coast to the troocean water that carries warm water from Florida to Greenland where it cools and sinks to 1000 meters or more before traveling back down the coast to the tropics.

The activity in the Greenland Sea is part of a global pattern of ocean movement, known as thermohaline circulation, or more commonly the «global conveyor belt.»

«Recent research, however, suggests that there is a possibility that this gradual global warming could lead to a relatively abrupt slowing of the ocean's thermohaline conveyor, which could lead to harsher winter weather conditions, sharply reduced soil moisture, and more intense winds in certain regions that currently provide a significant fraction of the world's food production.
