By December 5, 2020No Comments

An iceberg has broken off Pine Island Glacier (PIG) on the edge of Antarctica, according to, And it's a big one. They think the falling ice slab that was caught on camera probably weighed thousands of tonnes. Mass melting of the West Antarctic ice sheet, driven by warmer ocean temperatures, was … The shocking footage shows an ice slab that's at least 40 metres high hurtling towards the sea. The iceberg, dubbed D-28, split off from the Amery Ice Shelf in East Antarctica on Sept. 25, creating a free-floating mountain of ice more than 600 feet thick. The remaining ice shelves have also lost a significant amount of their area over time, with the Milne Ice Shelf being the last to be affected with it breaking off in August 2020. But climate change isn't to blame. 36, L15501 (2009). The loss of the Thwaites glacier could trigger the broader collapse of the West Antarctic ice sheet. An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Pugh is known for swimming in arctic water to raise awareness for climate change, but on January 23, he became the first person to swim in a supraglacial … The Antarctic minimum sea ice extent, which was noted in the previous post, was indeed reached on February 22. Like corks in a bottle, they block the ice flow and keep nearly 10 percent of the West Antarctic Ice Sheet from draining into the sea. This is by far the largest ice mass on Earth and is assumed to be less sensitive to climate change than other ice sheets simply because of its size. "Its floating ice front, which has an average thickness of approximately 500 meters, has experienced a series of calving events over the past 30 years, some of which have abruptly changed the shape and position of the ice front," the ESA said. The coast of West Antarctica is rapidly losing mass as warm water melts ice shelves from below and icebergs break off. The Pine Island Glacier recently spawned an iceberg over 300 square kilometers that very quickly shattered. Like corks in a bottle, they block the ice flow and keep nearly 10 percent of the West Antarctic Ice Sheet from draining into the sea. In 2002, a large piece of the nearby Larsen B ice shelf snapped off, but within a month - and quite unexpectedly - an even larger swath of the 10,000-year-old feature behind it rapidly disintegrated. The Sun website is regulated by the Independent Press Standards Organisation (IPSO), Our journalists strive for accuracy but on occasion we make mistakes. The chunk broke off from the Pine Island Glacier in Antarctica, which helps connect the West Antarctic Ice Sheet with the ocean, the agency says.

"What you are looking at is both terrifying and beautiful," Mark Drinkwater, head of the Earth and Mission Sciences Division at the ESA, told CNN. Wed 12 Feb 2020 18.30 EST. The 2020 maximum sea ice extent is the eleventh lowest in the 42-year satellite record, but the highest since 2013.

The same report claimed that according to satellite data, the Greenland ice sheet lost a record amount of ice in 2019, equivalent to a million tonnes per … ... the early 2000s and had predicted a large iceberg would break off … Do you have a story for The Sun Online Tech & Science team? While icebergs calving from glaciers is a natural process, Drinkwater made it clear that the rate of melting and calving being seen in West Antarctica is greater than anything observed in the satellite record. Ice shelves propping up two major Antarctic glaciers are breaking up and it could have major consequences for sea level rise By Helen Regan , CNN Updated 1043 GMT (1843 HKT) September 15, … The 1981 to 2010 median is in dark gray.

Arctic sea ice appears to have reached its annual maximum extent on March 5. An international team of researchers led by geoscientist Dr Kim Jakob from Heidelberg University has now examined the dynamics of the East Antarctic Ice Sheet more closely. A huge raft of ice has cleaved off the Antarctic peninsula and smashed into thousands of icebergs. It was hard to take in just how much was going on at the same time. Changes to the Antarctic ice sheet at the bottom of the southern hemisphere have been triggered by sea level changes in the northern hemisphere … The Pine Island glacier in #Antarctica has finally calved, creating many large icebergs! The breaking off of this large ice piece was technically the birth of a new iceberg. And, here's how Antarctica's ‘Doomsday Glacier’ Thwaites could collapse and send sea levels soaring. July 22, 2020 — Questions about the stability of the East Antarctic Ice Sheet are a major source of uncertainty in estimates of how much sea level will rise as the Earth continues to warm. Indeed, Pine Island’s ice has been flowing out to sea faster since the 1990s, with the ice stream now moving at a rate exceeding 35 feet per day, according to Drinkwater. A huge iceberg just broke off West Antarctica’s most endangered glacier. "Sea level rise can have huge economic and societal impacts. DAVE MOSHER, BUSINESS INSIDER . Shockingly, half of this melting occurred in the last five years. But if you weren't paying attention before, it probably is worth doing so now.

This phenomenon of calving isn't new for Pine Island Glacier, according to the ESA. Pine Island Glacier has a crack tens of kilometers long and is one of Antarctica's fastest flowing rivers of ice, moving 4,000 meters a year, according to the report. "Also, Antarctic ice shelves are currently losing most [of their] mass due to basal melting," or melting on the underside of the ice sheet, "in response to … Pine Island Glacier, along with its neighbor Thwaites Glacier, effectively act as arteries connecting the West Antarctic ice sheet to the ocean. Rothrock, "Decline in Arctic sea ice thickness from submarine and ICESat records: 1958 - 2008," Geophys. And only a few days later, the glacier, also referred to as PIG, "spawned piglets," ESA said -- in a process known as calving -- and "many large" icebergs were formed. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic.The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. A mathematics graduate student at the University of Sydney in Australia, Hester and researchers at … The two glaciers effectively act as arteries connecting the West Antarctic ice sheet to the ocean.

The Amery Ice Shelf in Antarctica has just produced its biggest iceberg in more than 50 years. Res. This sea-level fall reduced the exposure of East Antarctic ice to relatively warm ocean waters and thus minimised the potential of sea water to cause basal melt in parts of the ice sheet. Calving is the phrase used to describe when an iceberg is formed from breaking off of a glacier. And it's a … The ship that enabled the capturing of the footage had to leave the bay in a hurry due to fears that an even more catastrophic event could trigger a tsunami. Scientists aboard the ship are being filmed by Sky as they track the impact of climate change in the area.

The changes to the glacier have been mapped by ESA-built satellites since the 1990s, with calving events occurring multiple times since 1992. Instead, the melting is occurring due to warm ocean water melting the land ice around its edges, easing the transport of inland ice to the sea. The rest of Larsen B may splinter off by 2020. Details of previous record at https://t.co/19Un83mmHn#ClimateChange pic.twitter.com/ZKvzr765Am. Over the past 40,000 years, ice sheets thousands of miles apart have influenced one another through sea level changes, according to new research. The largest of them was so big, it was even given a name: B-49. "It is clear from these images (that the Pine Island Glacier) is responding to climate change dramatically," he added. The Larsen Ice Shelf in Antarctica has been calving icebergs for decades. The video was captured by James Clark Ross who is part of the Sky News British Antarctic Survey ship crew.

Shown below are up-to-date satellite observations of the sea ice covers of both the Arctic and the Antarctic, along with comparisons with the historical satellite record of more than 37 years. Violent noise from the glacier also suggested to the researchers that the ice was still unstable and could be ready for more iceberg 'calving' events. The event saw a collapse that stretched half a mile across the glacier. pic.twitter.com/iubE8JffVR, The Argentine research base Esperanza, on the northern tip of #Antarctic Peninsula, saw a new record temperature of 18.3°C today (old one 17.5°C on 24 March 2015), per @SMN_Argentina.
