Mussels were identified in 1.300 km from the North Pole, which is a new sign of a warming of the planet, scientists said Friday.
Blue mussels prefer common warmer waters off France or the eastern seaboard of the United States. But swarms were discovered last month off the Norwegian archipelago of Svalbard most of the year ice covered waters. "The climate is changing rapidly," said Geir Johnsen, a professor at the Norwegian University of Science and Technology. Shellfish are "a very good indicator of global warming." "They seem to mussels that we found were two or three years," he told Reuters.
Their presence had not been recorded off the islands since Viking times, 1.000 years ago, another period of warming. UN scientists say that the Arctic is warming faster than any other region because of carbon dioxide emissions and other greenhouse gases from fossil fuels. The melting of snow and ice discovers a darker ground or water that absorb more heat, accelerating warming more than the areas further south. In
comparison, ice in Antarctica is thicker and resistant to change.
In Canada, Inuit have seen for the first time robins, hitherto unknown in their area, and ice sheets until solid this gave way underfoot hunters. In Scandinavia, birch began to push further north into previously frozen regions where only reindeer were grazing.
