The largest glacier in Antarctica, which split up into a giant iceberg in July, is likely to continue its retreat, according to experts who say it is the largest single contributor to sea level rise in the region.
The Pine Island glacier generated an ice sheet of 720 sq km, after a crack was first spotted in 2011. Cracks occur naturally but in this case, warm ocean water brought by winds is thought to have played an important role.
Now scientists have said in an article in Nature Climate Change that even if temperatures get much colder, the retreat is likely to continue, as it sensitive to a marine ice sheet instability mechanism. They say that the grounding line, which separates the grounded ice from the floating ice shelf, has retreated by tens of kilometres.
Dr Hilmar Gudmundsson from the British Antarctic Survey said, “At the Pine Island glacier we have seen that not only is more ice flowing from the glacier into the ocean, but it’s also flowing faster across the grounding line… We also can see this boundary is migrating further inland.”
According to experts, the phenomenon will play a key role in future sea level rise.
“Pine Island glacier shows the biggest changes in this area at the moment, but if it is unstable it may have implications for the entire West Antarctic Ice Sheet”, Gudmundsson said.
“Currently we see around 3mm of sea level rise a year, and the Pine Island Glacier retreat could contribute an additional 3.5-10mm in the next 20 years, so it would lead to a considerable increase from this area alone. But the potential is much larger.”
