The Thwaites Glacier in West Antarctica — nicknamed the “Doomsday Glacier” because its collapse could cause catastrophic sea level rise — is the world’s widest glacier and roughly the size of Florida. Thwaites, which already contributes 4% to global sea level rise, holds enough ice to raise sea levels by more than 2 feet. “This process of widespread, enormous seawater intrusion will increase the projections of sea level rise from Antarctica,” he added. Sea ice around Rothera Point, on Adelaide Island to the west of the Antarctic Peninsula. The researchers also used climate models to predict the potential speed of recovery from such extreme sea ice loss and found that even after two decades, not all the ice will return.

They have discovered it started retreating rapidly in the 1940s, according to a new study that provides an alarming insight into future melting. The Thwaites Glacier in West Antarctica is the world’s widest and roughly the size of Florida. “Once an ice sheet retreat is set in motion it can continue for decades, even if what started it gets no worse,” he told CNN. While similar retreats have happened much further back in the past, the ice sheet recovered and regrew, Smith said. “Further events arising more from the warming climate trend took things further, and started the widespread retreat we’re seeing today,” he told CNN.

The world is off track in its efforts to curb global warming in 41 of 42 important measurements and is even heading in the wrong direction in six crucial ways, a new international report calculates. On the flip side, public money spent to create more fossil fuel use is going in the wrong direction and faster than it has in the past, said study co-author Kelly Levin, science and data director at the Bezos Earth Fund. The globe has already warmed about 1.2 degrees Celsius (2.2 degrees Fahrenheit) since the mid 19th century.

The study, published in the journal Nature Climate Change on Monday, found no matter the degree of warming this century, the melting of the West Antarctic Ice Sheet will speed up as warmer water in the Amundsen Sea erodes ice shelves bordering the ocean. These ice shelves buttress ice further inland, acting as a cork in a bottle that stops their flow into the ocean. The collapse of the West Antarctic Ice Sheet is one of nine global climate 'tipping points' scientists identified in 2009. If the ice sheet were to fully melt, average global sea levels would rise by more than a metre. Antarctic Sea ice saw its lowest maximum extent on record this winter.

☆ Climate change: Rapid melting of West Antarctica ice now 'unavoidable,' study finds
▼ + stars: | 2023-10-23 | by ( Rachel Ramirez | ) edition.cnn.com time to read: +5 min

CNN —Rapid melting of West Antarctica’s ice shelves may now be unavoidable as human-caused global warming accelerates, with potentially devastating implications for sea level rise around the world, new research has found. Even if the world meets ambitious targets to limit global heating, West Antarctica will experience substantial ocean warming and ice shelf melting, according to the new study published Monday in the journal Nature Climate Change. They act like buttresses, helping hold ice back on the land, slowing its flow into the sea and providing an important defense against sea level rise. While there has been growing evidence ice loss in West Antarctica may be irreversible, there has been uncertainty about how much can be prevented through climate policies. “The thing that’s depressing is the committed nature of sea level rise, particularly for the next century,” Scambos told CNN.

No matter how much the world cuts back on carbon emissions, a key and sizable chunk of Antarctica is essentially doomed to an “unavoidable” melt, a new study found. Researchers used computer simulations to calculate future melting of protective ice shelves jutting over Antarctica’s Amundsen Sea in western Antarctica. How much melting can still be prevented by reducing emissions?” said study lead author Kaitlin Naughten, an oceanographer at the British Antarctic Survey. In each case, ocean warming was just too much for this section of the ice sheet to survive, the study found. That part of Antarctica “is doomed,” said University of California Irvine ice scientist Eric Rignot, who wasn’t part of the study.

All told, Antarctic ice shelves lost about 8.3 trillion tons (7.5 trillion metric tons) of ice in the 25-year period, the study found. The largest of the Larsen ice shelves, Larsen C, has lost 1.8 billion tons (1.7 trillion metric tons) of ice, about one-eighth of its mass. The shelf has lost 70% of its mass since 1997 — about 4.1 trillion tons (3.7 trillion metric tons) — into the Amundsen Sea. The ice shelves on the east were growing slower than the shelves losing ice to the west.

☆ Antarctica is missing an Argentina-sized amount of sea ice – and scientists are scrambling to figure out why

Antarctic sea ice has fallen to unprecedented lows for this time of year. Every year, Antarctic sea ice shrinks to its lowest levels towards the end of February, during the continent’s summer. In mid-July, Antarctica’s sea ice was 2.6 million square kilometers (1 million square miles) below the 1981 to 2010 average. While natural climate variability affects the sea ice, many scientists say climate change may be a major driver for the disappearing ice. A lack of sea ice could also have significant impacts on its wildlife, including krill on which many of the region’s whales feed, and penguins and seals that rely on sea ice for feeding and resting.

☆ Greenland and Antarctic ice sheets are melting rapidly and driving sea level rise, new satellite data finds
▼ + stars: | 2023-04-20 | by ( Jack Guy | ) edition.cnn.com time to read: +4 min

CNN —The Earth’s ice sheets lost enough ice over the last 30 years to create an ice cube 12 miles high, according to new research. They found that ice sheet melting has increased six-fold over the past 30 years, as record levels of planet-heating pollution push up global temperatures. The worst year for ice sheet loss was 2019, the report found, when the ice sheets lost around 675 billion tons of ice. Ice sheet melting now accounts for a quarter of all sea level rise – a fivefold increase since the 1990s. Otosaka expects the Greenland ice sheet to continue losing ice, but said it’s not yet clear what might happen to the Antarctic ice sheet.

Becka Bower/Cornell University/Handout via REUTERSMEXICO CITY, Feb 15 (Reuters) - Scientists studying Antarctica's vast Thwaites Glacier - nicknamed the Doomsday Glacier - say warm water is seeping into its weak spots, worsening melting caused by rising temperatures, two papers published in Nature journal showed on Wednesday. As part of the International Thwaites Glacier collaboration - the biggest field campaign ever attempted in Antarctica - a team of 13 U.S. and British scientists spent about six weeks on the glacier in late 2019 and early 2020. "Warm water is getting into the weakest parts of the glacier and making it worse," Schmidt told Reuters. Scientists have previously depended on satellite images to show the behavior of the ice, making it difficult to get granular details.

Melting ice that could tip sea level rise into catastrophic levelsSource: NASA Ice ViewerChart: Annie Fu/InsiderWhile it's easier to plan for a steady sea level rise, scientists are very concerned about what would happen if huge chunks of ice collapse and abruptly change sea levels. The Antarctic ice sheet is much bigger than the ice sheet on Greenland. If they were to melt totally, the Greenland ice sheet would contribute about 23 ft to the sea levels, while the Antarctic ice sheet holds enough ice to raise sea levels by 58 feet. Local sea level variationGlobal mean sea level rise is only a snapshot of the whole picture. Because sea levels are influenced by the local environment, the sea level rise can be much higher locally than it is on a global scale.
