Unfortunately, all researchers can do at the moment is watch, wait and hope for the best. In 2016, a study published in Nature confirmed that if greenhouse gas emissions continue unabated, Antarctica could experience uncontrollable collapse over the next several decades.Īntarctica’s ice mass has the potential to contribute more than a 1-metre sea-level rise by 2100, and more than 15 metres by 2500. The iceberg that broke off from Antarcticas Larsen C Ice Shelf between July 10 and July 12 is gargantuan. The east coast of Antarctica is heating up quickly and is experiencing accelerated global warming. Since the beginning of satellite observations in the 1970s, the tip of the. "We don't think there is a strong link to climate change in terms of the provocation of the crack in question… but we couldn't work that out,” admitted O’Leary. East Antarctica’s Conger ice shelf a floating platform the size of Rome broke off the continent on March 15, 2022. ![]() Martin O'Leary, a researcher at MIDAS, told CNN the previous breaks were ‘“unequivocally climate change related,” however so far Larsen C has not been linked directly to global warming. Larsen A ice shelf gave way 22 years ago and Larsen B, 15 years ago, in what was the largest collapse on record. “This event will fundamentally change the landscape of the Antarctic Peninsula,” said Professor Adrian Luckman in a statement posted on the MIDAS website.Ĭlimatologists and Glaciologists warn that this event is yet another sign of global warming and rising sea levels. While it’s considered normal for an ice shelf to discard an iceberg every ten years, many fear that the rapidly growing crack is a sign of an inevitable decline and future instability of the entire region. When the iceberg carves off, the Larsen C Ice Shelf will lose just over 1,930 square miles, an equivalent of more than 10% of its area. While this is not the first time icebergs have developed this way in Antarctica, scientists are emphasising the significant impact it will have on the topography of the continent. Larsen C is cleaving along an impressive fault line. The iceberg, known as Larsen C, is ready to break off in spectacular fashion - rather than splintering at the edges and collapsing into smaller chunks like most icebergs. “If it doesn't go in the next few months, I’ll be amazed,” Professor Adrian Luckman lead researcher from Swansea University, told BBC News. Recent investigations show the rift now measures a staggering 175 kilometres in length, leaving a mere 20 kilometres of fragile ice connecting the vast iceberg to the Antarctic shelf. Scientists from the UK-based research team, Project MIDAS, have been monitoring the developing rift in the Larsen C Ice Shelf since 2014.Īfter months of steady and incremental growth, the division suddenly accelerated, adding an additional 18 kilometres in the second half of December 2016. NASA Scientists studying one of the most crucial glaciers thats been deteriorating by climate change got a new look at whats going on underneath the surface. s is 1 : 6) to the size categories 100200 m. ![]() The Thwaites Glacier, located on the West Antarctic ice sheet, is often nicknamed the "doomsday glacier" due to its size and its rate of disintegration.An iceberg, anticipated to be among the largest recorded, is positioned to break away from Antarctica. 1:00 Thwaites Glacier is seen in this undated photo. We assign a height of 50m (and an average thickness of 300 m i.e. A-23A is around 1,498 square miles (3,880 square km) in size. That record is held by an iceberg called B-15, which measured a massive 4,247 square miles, and broke off from the Ross Ice Shelf of Antarctica in March 2000.Īntarctica is the coldest and driest continent on Earth, containing around 70 percent of the planet's freshwater frozen inside enormous ice sheets. A-76 snatched first place as the world’s biggest iceberg from iceberg A-23A, also located in the Weddell Sea. While B-22A is a large iceberg, it isn't anywhere near the largest one ever recorded. Bigg, an emeritus professor of Earth system science at the University of Sheffield in England, previously told Newsweek. "Large ice sheets around Antarctica do occasionally calve large icebergs, just as part of the natural process of the ice moving towards the sea," Grant R.
