Researchers have discovered an incredible arctic landscape, hidden under the ice for 40,000 years.
This can be seen after the melting of the glacier on the Canadian island of Buffin, which it was very exciting for specialists, because it would prove that, in theory, the hottest year lasts 115,000 years.
According to a study by scientists at the University of Colorado in Boulder (USA), this destruction immediately took a look at the Arctic landscape, as reported last week in the journal Natural Communications.
“The Arctic is currently heating up two to three times faster than the rest of the world, so naturally, glaciers and ice caps will react faster”he expressed Simon Pendleton, principal author and researcher of the Institute of Alpine and Arctic Studies (INSTAAR), Live Science.
As they reported on the university portal, in August last year, experts took 48 samples of plants in 30 localities to determine their antiquity, and there they found that the ancient vegetation is 40,000 years old.
“We approached the edges of the retreating ice and took samples of newly exposed plants, preserved in these ancient landscapes, to find out when the last time the ice moved in this place. Because dead plants are effectively removed from the landscape, the radiocarbon age of rooted plants determines the last time that summer was on average as warm as in the last century. "says Pendleton.
And closed: "To be here and see that this change … I do not have a good word for this. You catch your breath. "
