Greenland’s ice melting past ‘tipping point’: study

Let’s Start this Interesting Article Shared on

Copenhagen: The melting of Greenland’s ice cap has increased so much that it is now irreversible, no longer able to compensate for ice loss due to snowfall, even though global warming is over today, according to researchers.
A statement from Ohio State University said, “Greenland’s glaciers have passed through a type of tipping point, where icebergs that change the ice sheet each year cannot escape the ice that flows into the sea from the glaciers.” The studies published on August 13 in Communications Earth and Environment are based.
Climate change is having a devastating impact on the world’s glaciers, melting ice poses a threat to millions of people around the world.
In the 1980s and 1990s, the ice cap lost about 450 billion tons of ice per year, which was offset by snowfall, scientists said after analyzing 40 years of data.
But the melting of ice has accelerated this century, climbed to 500 billion tons and is no longer sufficiently filled with ice.
“In the 21st century, Greenland’s ice sheet is decelerating at a rapid rate, making it the largest contributor to rising sea levels,” the study said.
While researchers agree that Greenland ice is melting, not everyone agrees that it has reached a ‘tipping point’.
“We don’t know how much greenhouse gas concentrations will increase,” climatologist Ruth Motram of Denmark’s Meteorological Institute told AFP.
Published results indicate that “even if we stabilize temperatures (and greenhouse gas emissions) at current levels, the ice sheet will still melt, but only as long as the size of the ice sheet is in equilibrium with the climate. May the bar be no more “said Mataram.
Another recent study by Britain’s University of Lincoln has concluded that Greenland’s expected ice melting contributes 10–12 centimeters to the world’s rising sea levels by 2100.
The United Nations’ IPCC Climate Science Advisory Panel said in 2013 that it expected sea levels to rise 60 centimeters by the end of the century.
