North Atlantic Deep Water North Atlantic Deep Water formation has been dramatically reduced at times during the past (such as during the Younger Dryas or during Heinrich events), and that this might correlate with a decrease in the strength of the Gulf Stream and the North Atlantic drift, in turn cooling the climate of northwestern Europe. There is concern that global warming might cause this to happen again. It is also hypothesized that during the Last Glacial Maximum (LGM), NADW was replaced with an analogous watermass that occupied a shallower depth known as Glacial North Atlantic Intermediate Water (GNAIW).

Norwegian Current increased warming of the North Atlantic Drift is a much larger contributor to the inhibition of formation of sea ice in the Arctic, than the contribution from the Norwegian Coastal Current. Hence, the impact of the Norwegian Coastal Current on climate change is relatively small. Norwegian Current The Norwegian Current (also known as the Norwegian Coastal Current) is a water current that flows northeasterly along the Atlantic coast of Norway at depths of between 50 and 100 metres through the Barents Sea Opening into the Barents Sea. It contrasts with the North Atlantic Current because it is colder and contains
