The Guardian says: «the Atlantic Meridional Overturning Circulation (Amoc), has weakened by 15 % since 1950, thanks to melting Greenland ice and ocean warming making sea water less dense and more buoyant.

This is not necessarily a contradiction to the other data series, because the two sediment cores used are located in the area of the deep outflow of Labrador Sea Water — but this is only one of two deep currents that together make up the southward part of the overturning circulation of the Atlantic, and thus the heat transport to the north.

Water temperature, «sea roughness», the changing patterns of oceanic circulation, and the use of carbon by marine creatures - all of these factors play up against one another.

The analysis revealed two major factors that could be contributing to the unusually large snowfall in recent winters — changes in atmospheric circulation and changes in atmospheric water vapor content — which are both linked to diminishing Arctic sea ice.

We work with global ocean circulation models to understand issues like the thermal expansion of ocean waters due to global warming or the effect of changing ocean currents on regional sea levels.

But, the flipside of this is that changes in the thermohaline circulation patterns can alter local water densities, and hence local water volumes, i.e., local sea levels.

Extreme scenarios of climate change predict changes in the site of deep - water formation and a weakening of thermohaline circulation, which could result in changes in the oxygenation and biogeochemical cycles in the bottom layers of the deep Mediterranean Sea [148].

An abrupt change in hydrography and large - scale circulation of the deep waters of the Eastern Mediterranean resulted from a unique, high - volume influx of dense waters from the Aegean Sea during the 1990s.

-LRB-- NAO) This sea ice then melts in the Sub Polar Atlantic, releasing fresh water into the sub - polar Atlantic waters, which in turn impedes the formation of NADW, which slows down the thermohaline circulation causing warm air not to be brought up from the lower latitudes as far north as previous while in lessening amounts.

An El Nino analysis released by the national weather service last week says sea surface and sub-surface temperature anomalies were consistent with El Niño during December, but the overall atmospheric circulation continued to show only limited coupling with the warm water.

«While no one expects our climate to change in the space of a few days, like the movie, we do know that fresh water flowing into our seas could dramatically affect sea levels and ocean circulation,» said study coauthor Alexander Forryan of the University of Southampton.

Um... while the oceans as a whole would have to cool, the sea surface would have to warm up substantially in order to transfer lots of heat to the air (and in order to warm up substantially, I suppose there would have to be reduced circulation with cold deeper waters).

Some of the warm water would be subducted by Atlantic Meridional Overturning Circulation / Thermohaline Circulation, some would be carried by ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade winds.

This resulted from the combined effects of high sea surface temperatures in open water areas and the effects of atmospheric circulation drawing warm air into the region.

The unusually high sea ice surface temperatures reflect a shift in ocean circulation, enhancing the import of warm, Atlantic - derived waters into the Arctic Ocean.

Ongoing changes in ocean circulation patterns, which are helping to drive warm water from other parts of the sea closer to the Antarctic continent, are also believed to be a major factor.

Much of the warming in the Arctic in the 20s and 40s, as well as in recent decades was likely due to increased ventilation of ocean heat after sea ice was reduced by intruding warm water and the altered atmospheric circulation.

The warmer - than - normal waters raised Sea Surface Temperatures and changed atmospheric circulation.

Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount of ice and water they discharge into the ocean, contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated melting also adds freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.7 (See Greenland ice sheet hotspot for more information.)

The antarctic sea ice is melted from below from the circulation of warmer waters under the sea ice.

The outgoing flow through Fram Strait carries with it large volumes of fresh water as fragmented pack ice, a flow that is strongly episodic at decadal scale and is associated with the series of so called Great Salinity Anomalies observed within the circulation of the subarctic gyre and in the Nordic seas that were discussed in the previous chapter.

Because of their large size, tabular icebergs often travel great distances, and their movement can affect ocean circulation, the formation of bottom water (the dense layer of water at the very bottom of the ocean) and sea ice, and the productivity of life - forms in their path.

In addition to the main threshold for a complete breakdown of the circulation, other thresholds may exist that involve more - limited changes, such as a cessation or diminishment of Labrador Sea deep water formation (Wood et al., 1999).

These results also increase our overall understanding of glacial − interglacial cycles by putting further constraints on the timing and strength of other processes involved in these cycles, like changes in sea ice and ice sheet extents or changes in ocean circulation and deep water formation.
