Polar bears threatened to destroy the North Atlantic warm
The latest research shows that flow from the Arctic waters of a North Atlantic ocean currents, water temperature reached its highest level in more than two thousand years. Scientists fear that global warming and rising sea temperatures caused by the phenomenon of melting ice will threaten the very survival of polar bears rely on ice.
Arctic waters from the North Atlantic to join the flow of ocean currents, the water temperature reaches the highest level more than two thousand years. According to the survey, this channel currents in summer in recent years, Greenland and Norway through the Gulf Stream Islands in the north between the average water temperature was 6 degrees Celsius, Roman and medieval times higher than the highest temperature recorded.
According to foreign media reports, scientists are concerned that due to global warming and rising sea temperatures caused by the phenomenon of melting ice will threaten the very survival of polar bears rely on ice. According to the researchers concluded that such changes will lead to global sea level rise and rapidly changing environment.
University of Colorado in Boulder scientists of the latest findings of the study, researchers in the seabed sediment reconstruction of microbial analysis, found that the channel currents in the summer the average temperature in 1890 to 2007 was about 5.2 degrees Celsius, while in 2000 years ago, only 3.4 degrees Celsius, and at present this data has reached 6 degrees Celsius.
