The discovery was due to the melting of a glacier on Canadian Baffin Island, although this also indicates that the hottest year of the last year would be the hottest. The specialists still can not believe it.
A amazing arctic landscape been discovered for researchers after being hidden under the ice for 40,000 years.
This could be glimpsed after the Melting of a glacier on the Canadian island of Baffin, which worries many specialists because it would leave in evidence, that in theory we live the hottest year for 115,000 years.

According to a study by researchers at the University of Colorado at Boulder, USA, this collapse immediately left the Arctic landscape, as reported last week by Natural Communications magazine.
"The Arctic is currently warming two or three times faster than the rest of the world, so naturally, glaciers and ice caps will react more quickly," said Simon Pendleton, lead author and researcher at the Arctic Ocean. Research Institute. Alpine and Arctic (INSTAAR), Live Science.

Worry about the shocking discovery they made in Greenland
"We went to the margins of the recessed ice and took samples from the newly exposed plants in these ancient landscapes to see when the last time the ice came in. As the dead plants are effectively removed From the landscape, the radiocarbon age of rooted plants defines the last time the summers were as hot, on average, as those of the last century, "said Pendleton.
And closed: "Being here and seeing that change is … I do not have a good word for that, it takes your breath away."
