Climate researchers are doing their best to calculate the speed and potential height that the sea level will rise.
They found some new clues on the seafloor that’s around Antarctica. A study that’s been just released is suggesting that some of the continent’s floating ice shelves can melt back by six miles per year during eras of rapid warming.
This is definitely much faster than the ice retreat that’s been observed by the satellites.
Global warming speeds up the Antarctic meltdown
Global warming is speeding up the Antarctic meltdown and the findings in the study seem to have set up a new upper limit for the worst-case scenario, according to the director of the Scott Polar Research Institute at the University of Cambridge.
Inside Climate News reveals that the estimate of the ice shelf retreat is based on a patter of ridges that’s been discovered on the seafloor near the Larsen Ice Shelf.
The spacing and the size of the ridges is suggesting the fact that they were crated as the floating ice shelves rose and fell with the tides while they were shrinking back from the ocean.
The ice would have retreated by 150 feet/day
It’s been also revealed that the study published in Science reports that “researchers estimate that to corrugate the seafloor in this way, the ice would have retreated by more than 150 feet per day for at least 90 days.”
If the rate of retreat that’s been estimated by the news study should be extended across an 18 mile-wide and half-mile-thick ice shelf, experts said that “it would release 138-gigatons of ice per year— three to five times more ice than is currently lost annually from that glacier system.”
