Mussels have been spotted just 1.300 km from the North Pole, which is another indication of global warming, scientists said on Friday.
Blue mussels usually prefer warmer waters off the coast of France or the east coast of the United States. But swarms were discovered last month off the Norwegian archipelago of Svalbard, in ice-covered waters most of the year. "The climate is changing rapidly," said Geir Johnsen, professor at the Norwegian University for Science and Technology. Molluscs are "a very good indicator of global warming". "It looks like the mussels we found are two or three years old," he told Reuters.
Their presence had not been recorded off these islands since the time of the Vikings, 1.000 years ago, another period of warming. United Nations scientists say the Arctic is warming faster than any other region due to the emissions of carbon dioxide and other greenhouse gases from fossil fuels. Melting snow and ice discovers darker soil or water that absorbs more heat, accelerating warming more than regions further south. In
By comparison, the ice in Antarctica is thicker and resists warming.
In Canada, the Inuit saw for the first time robins, hitherto unknown in their region, and previously solid patches of ice gave way under the feet of hunters. In Scandinavia, birch trees began to grow further north, in formerly frozen regions where only reindeer would graze.
