Serhat TUNAR -TDO- Scientists at the United States Department of Aeronautics and space (NASA) have warned that a large ocean current in the Arctic could change direction as temperatures rise, and that such a change could lower temperatures in Western Europe.
The circular current, called the Beaufort Loop, travels clockwise around Canada's North and Alaska, west of the Arctic Ocean, where it collects fresh water from naturally melting ice, river runoff and rainfall. This fresh water protects sea ice from salt water melting faster and helps keep the north of the planet cool.
However, the increasingly rapid melting of ice due to climate change, the unusual amount of fresh water in to the air flow and this means the tide move faster, and causes them to become more turbulent.
Using 12 years of satellite data, the scientists measured how this circular current balanced an unprecedented amount of cold fresh water flow, and how that balance could be disrupted in a short time.
