The mussels are getting closer to the North Pole, a sign of warming,

Mussels were spotted at 1.300 km only from the North Pole, which is a new indication of a warming of the planet, said scientists Friday.

Blue mussels prefer ordinary warmer waters off France or the east coast of the United States. But swarms were found 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". "They seem 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, there is 1.000 years, another period of warming. United Nations scientists say the Arctic is warming faster than any other region because of carbon dioxide and other greenhouse gas emissions from fossil fuels. Melting snow and ice discovers darker soil or water that absorbs more heat, accelerating warming more than areas further south. In
comparison, the ice in Antarctica is thicker and resists warming.

In Canada, Inuit have for the first time seen robins, so far unknown in their region, and so far patches of ice have fallen beneath hunters' feet. In Scandinavia, birches began to grow further north in previously frozen areas where only reindeer would graze.
