The recent troubling news from the Antarctic Peninsula region gives a threat to the Larsen C, a Scotland-sized ice shelf is an imminent risk of collapsing. This reminds us the Larsen B shelf, which collapsed in the year of 2002.
In Science magazine, researchers from the University of Bristol, Britain reported a suite of the glacier, which is located north to Larsen B and C in the southern Antarctic Peninsula. By using gravity and satellite measurements, the team has found that the majority of the area in Larsen C, is being destabilized since 2009. As a result of this, drastic rise of sea level and will bring out many losses to the people in this world.
Jonathan Bamber of the University of Bristol, one of the paper’s authors said,
“This is one of now three really quite substantial signals that we’ve seen from different parts of West Antarctica and the Antarctic peninsula that is all going in the same way,”
The main cause of this effect is that, warmer waters are making the base of the submerged ice shelves to melt, and this made ice shelves to melt. Thereby, larger glaciers held by ice shelves have collapsed into the sea. Nowadays, this is becoming a common thing in the Antarctic region and similar mechanism has happened in nearby West Antarctica.
“The geometry of the bedrock … it’s below sea level and it dips inland” “That geometry means that the grounding line is potentially unstable.” “It only needs to change position slightly for it to move quite rapidly, and for a sustained period, further inland,” Bamber continues. “That’s the theory behind the instability of these sectors of West Antarctica and the peninsula.”
According to the reports, the region is losing 56 gigatons of ice per year and the rate is being increased tremendously while comparing to previous years. The paper says that the glaciers are unstable and will slopes further soon. The paper concludes that destabilization of the inland ice regions results in a huge amount of mass loss to the ocean, results in an immense rise in sea level.
