Global warming and emissions of greenhouse gases are having a massive impact on Earth’s atmosphere. Most notably, Antarctica’s massive ice sheets, including glaciers, have started melting. As a result, water from the melted ice is contributing to increasing sea levels. Before this, many pieces of research have revealed that the ice is melting at a faster pace. Similar is the latest study, which shows schemas of thinning of Antarctica’s largest glacier. The researchers from the University of Bristol have used ESA’s (European Space Agency) latest high-tech satellite technology. While analyzing the data, they have tracked trends of massive loss from Antarctica’s largest glacier – Pine Island.
The team has discovered that the form of thinning is developing in challenging ways in both aspects, i.e., time and space. As per the researchers, the thinning rates now are the highest along the glacier’s slow flow margin. Meanwhile, since 2007, the pace in the fast-flowing dominant trunk has lessened by about a factor of five. Notably, the cases are adverse to what researchers had observed a decade ago. Pine Island has remained a significant contributor to rising sea levels for the past forty years than Antarctica’s other glaciers. Although, various model estimations of future ice loss offer contrary outcomes. Some pinpoint melting of ice could drastically increase in the upcoming few decades. On the other hand, other findings specify an adequate response.
Meanwhile, the outcomes of the latest study, released in the journal Nature Geoscience, indicate the speedy relocation of the mass or grounding line. It is the location where the grounded ice meets the ocean for the first time. In its place, the outcomes uphold model replications that suggest the glacier will continue to melt but not at far higher rates than existing. Prof. Jonathan Bamber, leading author of the study, said it could look like good news, but it’s essential to recall that the glacier may continue to lose mass in the future. He added the pace might also increase in the future. Prof. Jonathan said, in the study, they have not made estimations. He said with the help of this new information; they can enhance model predictions for this region of Antarctica.
