Experts: Greenland’s ice melt won’t stop soon

According to a German study, a critical point in parts of the Greenland ice sheet, from which the melting point can barely be stopped, will soon be exceeded.

The Potsdam Institute for Climate Impact Research (PIK) announced Monday, citing the Potsdam Institute for Climate Impact Research (PIK), that due to rising temperatures, destabilization has already begun in the midwestern regions. Even with limited global warming, melt could then continue.

“We have found evidence that the midwestern portion of the Greenland Ice Sheet has been shaken,” explained PIK scientist Niklas Bowers. “Our results indicate that there will be a significant increase in avalanches in the future – which is extremely worrying.” Thus the cause is the feedback effects, where the temperature of the ice sheet progresses faster as its height decreases.

In order to prevent melting, not only will the warming stop, but temperatures will have to drop below the pre-industrial level in order to return to the height of the ice sheet of past centuries. “In practice, the current and projected loss of ice in the near future will be largely irreversible,” Bowers said. “So it is time to rapidly and dramatically reduce greenhouse gas emissions from burning fossil fuels and stabilize the ice sheet and our climate again.”

According to the results of the previous model, according to PIK, melting of the Greenland ice sheet is inevitable from a critical global average temperature threshold of 0.8 to 3.2 ° C above pre-industrial levels. Once this threshold is crossed, the ice sheet could completely melt over hundreds or thousands of years, which could lead to a global sea level rise of more than seven meters and the collapse of the Atlantic Zidial Circulation (AMOC) responsible for the relative temperatures in Europe and North America are to blame.
