An incredible Arctic landscape was discovered for researchers after being hidden under ice for 40,000 years.
This can be glimpsed after the melting of a glacier on the Canadian island of Baffin, which worried the experts a lot because it would make it clear that in theory the hottest year is lived for 115,000 years.
According to a study by researchers at the University of Colorado at Boulder, this collapse left the Arctic landscape at a glance, as reported last week in Natural Communications.
"The Arctic is heating up two or three times faster than the rest of the world, so naturally the glaciers and the polar ice caps will react faster"he expressed Simon Pendleton, lead author and researcher at the Institute of Alpine and Arctic Research (INSTAAR), Ciência Viva.
Speaking on the University portal last August, experts collected 48 plant samples from 30 locations to determine their antiquity, and found there that the ancient vegetation is 40,000 years old.
"We traveled to the retreating ice sheets and collected samples of newly exposed plants preserved in these ancient landscapes to find out when the ice was last in the area. Since dead plants are efficiently removed from the landscape, the radiocarbon age of rooted plants sets the last time summers were as hot on average as those of the last century. "says Pendleton.
