There is some evidence to suggest that an increase in global temperature may reduce the amount of sea ice formation. A decrease in the amount of sea ice formation would reduce the formation of bottom water. Because of the importance of bottom water in global thermohaline circulation, heat transport to the poles from the equator would decrease if thermohaline circulation slowed or stopped.
Polar regions would get colder because they would not be receiving as much heat. For example, according to IPCC reports, scientists predict that in the Atlantic ocean basin, thermohaline circulation will slow over the course of the 21st century. If the Atlantic ocean basin thermohaline circulation were to stop, the climate in western Europe could be affected.
However, the IPCC reports that it is unlikely that thermohaline circulation would abruptly stop, and there is currently no indication that a shutdown of thermohaline circulation is occurring. Furthermore, regional warming due to an increased greenhouse effect would likely initially cancel out the effects of cool westerly winds.

Bottom Water Currents The formation of dense bottom water near the poles forms a cold layer of ocean water on the ocean floor. He has conducted more than 60 scientific expeditions in the Arctic, Atlantic, Pacific, and Indian Oceans.
Sunita L. Her research explores how the larvae of seafloor invertebrates such as anemones and sea stars disperse to isolated, island-like habitats, how larvae settle and colonize new sites, and how their communities change over time.
Kirstin also has ongoing projects in the Arctic and on coral reefs in Palau. Her work frequently takes her underwater using remotely operated vehicles and SCUBA and carries her to the far corners of the world. January 4, The long memory of the Pacific Ocean.
