A foot or more of global sea level rise is now locked in due to widespread Greenland ice loss, and new research indicates that even if the world stopped emitting greenhouse gases today, there would be no way to halt it.
Greenland ice loss
The study, published Monday in the journal Nature Climate Change, found that the overall ice loss from Greenland’s ice sheet will trigger at least 10 inches of sea level rise, no matter the climate warming scenarios.
That’s generally the same amount that global seas have already risen over the last century from Greenland, Antarctica and thermal expansion (when ocean water expands as it warms) combined.
Researchers from the Geological Survey of Denmark and Greenland observed changes in ice-sheet volume in and around Greenland and saw that meltwater runoff has been the primary driver.
This water is technically already under the bridge.
While the authors did not specify a timeline, they predict that the change in sea levels …
