Melting ice in Canada reveals previously hidden arctic landscapes for 40,000 years

Ice-blended ice collections in Canada have resulted in an oversight of arctic landscapes that have been hidden in Europe for 40,000 years.

A group of researchers from the University of Colorado Boulder have found significant seasonal warming in the last decades has led to Baffin Island, the area being studied, has suffered its warmest temperatures over the past century. ; more than that of any century during the last 115,000 years.

The results are accidental and, after conducting the study, researchers were able to examine 48 samples of plants obtained from the margins of 30 different ice caps, all of which are 40,000 from years.

"The Arctic is heated twice three times faster than the rest of the world at the moment, so glacial glaciers and ice lids will respond faster," said Simon Pendleton, lead author and doctoral researcher at the Institute CU Boulder Arctic and Alpine Research.

"We are traveling to the growing green edges, samples of newly-exposed plants are kept on these ancient landscapes and carbon dating to plants to having a sense of when the ice had developed higher over that location, "added Pendleton. "Because dead plants are effectively removed from the landscape, the radiocarbons of plant age have been rooted and defined last time in such moments warm, on average, like the last century. "

The plants that the sampled team had buried under glacial ice for more than 40,000 years. Pendleton added that they had been "almost continually buried" since the last glacier that came over 120,000 years ago.

Of such a global warming rate, researchers predict Baffin Island could be completely ice-cream in the next few centuries.
