Greenland could lose more ice this century than in the last 12,000 years


In Greenland, the mass loss of the ice sheet could be during this century higher than that recorded at any time in the past 12,000 years, a study published by the British scientific journal Nature warns.


Predictions made by experts from Buffalo University and the University of Alaska Fairbanks, both in the United States, from high-emission simulations of carbon dioxide (CO2) in scenarios in southwestern Greenland, estimate this.

Plate thaw in Greenland

Their findings provide further evidence on the need to reduce greenhouse gases to prevent melting in that area of The Earth from contributing to sea level rise.

"Basically, we have altered our planet so much that the rhythm of plate thaw this century is on track to be much higher than the one that has occurred naturally at any time in the last 12,000 years," says one of the study's authors, Jason Briner, of Buffalo University in a statement.

The expert recalls that, as the Arctic heats up, the loss of mass in Greenland's glacial ice cap has "increased considerably" since the past 1990s, contributing to sea level rise.

For their research, scientists designed "high-resolution simulations" from geological observations in the southwestern part of that Danish territory, ranging from the past 12,000 years to the year 2100.

Energy diet

"If the world were to apply a strict energy diet, in line with the scenario that the Intergovernmental Panel on Climate Change calls CPR2.6 (limited warming), our model predicts that the thaw rate this century would only be slightly higher than that recorded at any time in the past 12,000 years," Briner observes.

However, in a "worrying scenario" of CPR8.5 emissions, which "currently follows" Greenland's glacial cap, the rate of mass loss could be up to "four times higher" than that recorded "under natural climate variability". EFEverde
