Scientists have found organic soil 10,000 feet beneath the icing sail that stretches across 80 percent of Greenland . The discovery reveals that the central area of Greenland ’s tundra — once cross with forests — was locked off and keep up , as if in an icebox .
“ The traditional knowledge about glaciers is that they are very powerful agentive role of corroding and can effectively strip a landscape painting clean , ” order Lee Corbett , a University of Vermont ( UVM ) grad scholar who is a co - writer of a written report appear inScience . “ We establish that the Greenland Ice Sheet is not roleplay as an agentive role of erosion ; in fact , at its center , it has performed fantastically picayune erosion since its inception almost three million years ago . ”
“ Rather than scrap and sculpture the landscape , the ice piece of paper has been frozen to the ground , like a gargantuan deep freezer that ’s keep an antique landscape painting , ” tot up Paul Bierman , a UVM geologist , who is the lead generator of the study .
Greenland is a place of great interest to scientists and policymakers studying global climate alteration , since its vast ice plane can reveal how other frappe sheets in Alaska and Antarctica will melt and uprise in response to change in globose temperature . The magnitude and rate of sea level rise due to the melting of chicken feed stay on uncertain factors in climate example .
The ice sheet hatch Greenland ’s tundra has not disappeared during the span of time in which human existence emerged a species . “ But if we keep on our current trajectory , the glass tabloid will not live , ” says Bierman . “ And once you clear it off , it ’s really strong to put it back on . ”
