Scientists warn that Greenland could melt completely back to 400,000 years after


Greenland could melt completely and irreversibly if global warming reaches 1.6 degrees Celsius, according to a study by the University Complutense of Madrid (UCM) and the Institute Potsdam (Germany).

The research, conducted by the Department of Physics of the Earth II of the UCM and scientists of the Potsdam Institute for Research on Impact

Climate (PIK), confirms that the polar cap is more vulnerable to global warming than previously thought.

This research used computer simulations of the ice in this region and its climate, calculating the evolution of the island during previous glacial cycles and the future of ice.

Therefore, this new estimate of the critical temperature threshold for the survival of the island is more reliable than before.

According to the study, now global warming is 0.8 degrees Celsius above the temperature in pre-industrial levels.

So far, previous studies placed the melting of Greenland in a temperature increase of about 3.1 degrees, a calculation that, as this research is "optimistic."

The study also warns that, although the weather returned to its pre-industrial state, melting prevent new growth above the polar cap on the island.
