It is possible, he adds, that these persistent high - pressure zones may be produced by two well - known oceanographic patterns: La Nina and El Nino in the Pacific Ocean (which mark alterations in warmer and cooler conditions between that ocean's eastern and western equatorial waters) and the North Atlantic Oscillation (which results from weather patterns between Iceland and the Azores).

But increasingly warmer summer temperatures are melting the ice of the Bering Strait and Northwest Passage, opening a water highway between the Pacific and the Atlantic.

Observations and the high - resolution climate model CM2.6 show a strong relationship between a weakening Atlantic Meridional Overturning Circulation (AMOC) and an increase in the proportion of warm - temperate slope water entering the U.S. Northeast Continental Shelf, primarily through the Gulf of Maine's Northeast Channel.

The argument is that the increased separation of the Antarctic land mass from South America led to the creation of the powerful Antarctic Circumpolar Current which acted as a kind of water barrier and effectively blocked the warmer, less salty waters from the North Atlantic and Central Pacific from moving southwards towards the Antarctic land mass leading to the isolation of the Antarctic land mass and lowered temperatures which allowed the ice sheets to form.

The warm Atlantic water continued to flow into the icy Nordic seas during the coldest periods of the last Ice Age.
