A Florida-sized glacier in the western Antarctic is currently holding back enough ice to raise sea levels around the world by 10 feet. And a new study found its safeguards could collapse in less than a decade, in the video published on Dec 30, 2021, “‘Doomsday Glacier’: Experts Raise Alarms About Cracking Antarctic Ice Shelf“, below:
After last week’s news about the potential Thwaites Glacier collapse, scientists now say Antarctic ice sheet melting could increase sea levels by over five meters by the year 3000 if current warming trends continue, according to a Journal of Glaciology study. The ice sheet’s sea level contribution without reductions in emissions of greenhouse gases has already been assessed as rising between 7.8 and 30 centimeters by 2100, and now further simulations of mass ice loss show that by the year 3000, a continuation of current climate conditions would produce between 1.5 to 5.4 meters of increase. Such rises would make large areas of densely populated coastal land uninhabitable, while reducing emissions could allow for a rise of only 0.13 to 0.32 meters. The main mechanism behind the worst-case-scenario rise is the potential collapse of the West Antarctic ice sheet, according to a study press release on Eurekalert. The sheet is grounded on a bed that is mostly well below sea level, meaning ocean currents can deliver warm water to the area where the ice attaches to the bed. NASA’s website explains this is the first step in a potential chain reaction, where ocean heat eats away at the ice, the grounding line retreats inland and ice shelves lose mass. When ice shelves lose mass, they can no longer hold back inland glaciers, so those glaciers can accelerate toward the ocean and thin as a result of that acceleration. This process then causes more acceleration and more thinning, and as more ice flows to sea every year, sea levels rise. The U.S. National Oceanic and Atmospheric Administration says sea levels have already risen between 21 to 24 centimeters since 1880, and the rate has more than doubled from 1.4 millimeters per year throughout most of the 20th century to 3.6 millimeters per year from 2006 to 2015, in the video published on Dec 28, 2021, “Doomsday Glacier 2021: Thwaites Gacier Collapse Could Provoke ‘Don’t Look Up’ Level Disaster“, below:

In a report presented at the world’s largest earth science conference this week, researchers revealed that the ice shelf on the Thwaites Glacier in Antarctica could collapse in just a few years. CBS News meteorologist and climate specialist Jeff Berardelli joins CBSN’s Lana Zak to explain how this might impact the world, in the video published on Dec 16, 2021, “Ice shelf on Antarctica’s “doomsday glacier” could shatter in next 5 years, researches warn“, below:
A warming atmosphere is creating concern in the Arctic Circle and on the continent of Antarctica. The Arctic Report Card shows high temperatures, shrinking sea ice and extreme melting events are transforming the region. At the opposite pole, in Antarctica, a key ice shelf that sits in front of the Thwaites Glacier could break up much sooner than expected — within 5 years. William Brangham reports, in the video published on Dec 15, 2021, “Melting of the Thwaites Glacier could rewrite the global coastline“, below:
Educational festival Antarctica Month 2021 officially launched on Antarctica Day (1 December), and we have some great videos to share throughout the month! In this video, join Dr. Anna Crawford, Postdoctoral Researcher at St. Andrews University, to explore ‘Understanding Thwaites Glacier’. This talk was recorded at the National Maritime Museum, Royal Museums Greenwich, during pre-COP26 event, in the video published on Dec 14, 2021, “Understanding Thwaites Glacier – Dr. Anna Crawford“, below:
