That's a "no shit, Dick Tracy" headline, capiche? An ocean current that runs into the Arctic Ocean is warmer than its been for 2,000 years.
A North Atlantic current flowing into the Arctic Ocean is warmer than for at least 2,000 years in a sign that global warming is likely to bring ice-free seas around the North Pole in summers, a study showed.
Scientists said that waters at the northern end of the Gulf Stream, between Greenland and the Norwegian archipelago of Svalbard, averaged 6 degrees Celsius (42.80F) in recent summers, warmer than at natural peaks during Roman or Medieval times.
"The temperature is unprecedented in the past 2,000 years," lead author Robert Spielhagen of the Academy of Sciences, Humanities and Literature in Mainz, Germany, told Reuters of the study in Friday's edition of the journal Science.
The summer water temperatures, reconstructed from the makeup of tiny organisms buried in sediments in the Fram strait, have risen from an average 5.2 degrees Celsius (41.36F) from 1890-2007 and about 3.4C (38.12F) in the previous 1,900 years.
The findings were a new sign that human activities were stoking modern warming since temperatures are above past warm periods linked to swings in the sun's output that enabled, for instance, the Vikings to farm in Greenland in Medieval times.
"We found that modern Fram Strait water temperatures are well outside the natural bounds," Thomas Marchitto, of the University of Colorado at Boulder, one of the authors, said in a statement.
The Fram strait is the main carrier of ocean heat to the Arctic.
Of course the dickish deniers will probably say something along the lines of god providing a Northwest Passage, the one that so many died trying to find. My emphases.
But....BUT... it's snowing! How can this be global warming?
