Scientists do not directly attribute the new glacier's calving to climate change, as such shifts in ice shelves are considered natural, but scientists agree climate change contributed to the disintegration of both Larsen A and Larsen B ice shelves, beginning in the 1990s. “It’s like your ice cube in your gin and tonic-it is already floating and if it melts it doesn’t change the volume of water in the glass by very much at all,” Anna Hogg, a glacier expert from the University of Leeds, told The Guardian. Sea levels will not immediately rise, according to Project MIDAS, as A68 was already floating, but further destabilization of the ice shelf could lead to its collapse, which would contribute to rising sea levels. Scientists say the event was expected and. During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North Atlantic Ocean around Greenland, triggering abrupt climate change impacts across the globe. ![]() "Some of the ice may remain in the area for decades, while parts of the iceberg. A massive 600-square-mile iceberg separated from Antarctica last week in the second major break-awayor calvingfrom the area in the past two years. READ MORE: Giant iceberg breaks off from Antarctica."It may remain in one piece but is more likely to break into fragments," Adrian Luckman, a professor at Swansea University and lead investigator of Project MIDAS, told Reuters. "Most of the time they have nothing to do with climate change." "But they're just part of how Antarctica's ice sheet works," he added. ![]() "These large iceberg calvings, sometimes as large as a small state, are spectacular," Ted Scambos, a senior research scientist at the University of Colorado at Boulder, told the WaPo. Back in 2021, another massive - albeit slightly smaller - chunk of ice broke off of the same Antarctic shelf, an event that scientists say was also unrelated to our changing climate. It's not the first recent Brunt Ice Shelf break. ![]() British Antarctic Survey January 24, 2023 □ Sentinel-2 & thanks to for the before shot from 20 Jan. Here's a super sharp view of the vast new #iceberg breaking away from the Brunt Ice Shelf in #Antarctica. A satellite image showed a piece breaking off the end of A68a. "This calving event has been expected and is part of the natural behavior of the Brunt Ice Shelf," said BAS glaciologist Dominic Hodgson in the statement. The iceberg drifted slowly through the icy Weddell Sea for a few years, before picking up steam as it entered the Southern Ocean. " calved after cracks that have been developing naturally over the last few years extended across the entire ice shelf," reads a press release by the British Antarctic Survey (BAS), which captured images of the event, "causing the new iceberg to break free." Scientists have been monitoring Chasm-1 closely in the years since, anticipating a future break. In fact, researchers who are observing the unstable ice sheet have found that it is speeding up, indicating that a massive iceberg could break off. Roughly ten years ago, as The Washington Post reports, scientists detected new growth in Chasm-1, a crack in the ice shelf that was long considered dormant. Antarcticas Larsen C ice sheet is flowing fast. Scientists say that rising global temperatures had nothing to do with the iceberg calving incident. "It is not linked to climate change." Breakin' FreeĪ gigantic iceberg twice the size of New York City has separated itself from Antarctica's 500-foot-thick Brunt Ice Shelf, as captured in new satellite imagery - and, for once, the climate crisis isn't to blame. ![]()
