Despite the discovery of this land mass we don’t really know much about it. This has led to a combined 17.8 mm rise in sea-level, of which 10.6 mm (60%) is caused solely by Greenland ice losses, while 7.2 mm (40%) is due to the thawing of Antarctica. Racing to Find Answers in the Ice. But the patterns in this region match up nearly perfectly with conditions far away, in the tropical Pacific Ocean, where much better, longer-term records exist—so the team could extrapolate how the polar-region winds have changed over the last century. When that happens, seas rise. Our Tiny Room. Antarctica might be emerging as a popular alternative vacation option, but it's not likely many would want to live there months on end like the hardy Russian researchers hunkered down at Vostok Station.. Recent uprisings in France reveal the contrary. It’s now happening in Antarctica and scientists are worried. Science news in brief, from bat-winged dinosaurs to penguin poo. But Antarctica is a complicated place that changes a lot because of natural variability, so it has been challenging to pinpoint the extent of human influence on the changes. He is a tireless reader, whose interests range from P. G. Wodehouse through Karl Marx to Roger Scruton. But about a century ago, pieces of it started to retreat in measurable ways. Some scientists manning lonely outposts under the drifting and shifting aurora are nearly paralyzed with fear. The changing westerlies may also help explain the seemingly unusual changes happening elsewhere in Antarctica. Antarctica. This website uses cookies to improve performance and enhance your user experience. What is happening to ice in Antarctica, and why does the reality of ice loss or gain on Earth’s southernmost continent seem so elusive? Pine Island Glacier and Thwaites Glaciers, for example, are losing about 100 billion tons of ice each year, and more in bad years. That’s well within the time frame when carbon dioxide and other greenhouse gases had started to accumulate thickly in the atmosphere, so it seemed logical to think that human influence was affecting the ice. (See what the world would look like if all the ice melted away). What do you think, is this an early warning of a larger problem? But understanding what is happening here is essential for scientists to be able to predict future sea level rise accurately. Find out more at Eureka Report. All rights reserved. There are glaciers on all continents except Australia. And how can we limit deforestation if urban areas will have to expand inland in order to relocate millions of coastal inhabitants? To be honest, I just brushed it aside. Also, we should consider that we could be wrong strategically. All rights reserved. Timothy is an aspiring journalist and recent graduate in Politics, Philosophy and Economics at LUISS University, Rome. He specializes in European, British and American politics and international conflict zones. New studies in Antarctica have found a fresh danger zone and while it may not spell apocalyptic sea level rise by 2100, it certainly presents bad news. For years, scientists have watched and learned that those glaciers are crumbling and melting, the rate speeding up over the decades and imperiling the stability of the entire ice sheet. 2016 continues to be a momentous year for the world’s climate, on track to be the new hottest year on record.. To our south, Antarctica has also just broken a new climate record, with record low winter sea ice.After a peak of 18.5m square kilometres in late August, sea ice began retreating about a month ahead of schedule, and has been setting daily low records through most of September. Me Driving The Delta. The glaciers have been receding because their snouts spill over the edge of the continent into the surrounding ocean, which is warmer than the ice. Tour operators are tapping a huge and ever increasing demand to visit the Earth's last great wilderness. measurements from Antarctica’s Pine Island Glacier (P.I.G.) Keeping future greenhouse gas emissions in check would go a long way toward keeping those crucial winds from weakening further, the water under the edge of the ice chilly, and the ice frozen. The hacktivist group Anonymous have ‘revealed’ the chilling (Get it, because it’s cold there) secret the U.S. government discovered in Antarctica back in the 1940s. These epochal phenomena are driven by a force of nature that dwarfs our petty human ‘initiatives’, and the question we should ask ourselves is whether the solutions so far presented by our ruling classes may do us more harm than good. Underwater Diving. Scientists knew that the strength of the winds in this region of the Amundsen Sea affected the water temperature. Scientists came to that conclusion after systematically computing gains and losses across 65 sectors of Antarctica where large glaciers - or glaciers flowing into an ice shelf - reach the sea. 2016 continues to be a momentous year for the world's climate, on track to be the new hottest year on record.. To our south, Antarctica has also just broken a new climate record, with record low winter sea ice.After a peak of 18.5m square kilometres in late August, sea ice began retreating about a month ahead of schedule, and has been setting daily low records through most of September. https://coolantarctica.com/Antarctica fact file/science/global_warming.php These include such particular measures as carbon taxes, which only hurt the poorer among us and are of dubious efficacy, or more general panaceas from on high like the paraded Green New Deal, effectively beckoning forth the end of the global economy as we know it. “The effects will be global, because sea level will rise globally.”, Photograph by Jeff Schmaltz, NASA/GSFC/MODIS Land Rapid Response Team, West Antarctica is melting—and it’s our fault, See the crack splitting an Antarctic ice shelf in two. Antarctic Dispatches 1 2 Part 3. Yesterday, someone asked me to do some research into bad boy MR. Skull and Bones, John Kerry. (Illuminati Exposed) (2017) Share The Video & Subscribe To Stay Updated ! Furthermore, the news came a week after Argentina’s National Meteorological Service — in operation since 1961 —registered the hottest day on record for Argentine Antarctica: 18.3 degrees Celsius (65F) at midday at the Esperanza base, it too located near the northernmost point of the peninsula. Your email address will not be published. Lakes on Signy Island in the Maritime Antarctic for instance have shown possibly the fastest local response to regional climate found anywhere on Earth. This year’s sea ice growth continues a long-term trend of increasing sea ice around Antarctica. But over the last century, that balance has come undone. Is P.I.G. In the Arctic, which is losing sea ice all the time, it's possible that the reverse process is happening. View on Map . Antarctica: 60% of ice shelves at risk of fracture, research suggests. WHAT IS HAPPENING IN ANTARCTICA? The glacier ice is attached the “rim” of the bowl, but if it melts back past that edge, warm ocean water can spill underneath it and melt it even more quickly from the bottom. Iceberg ‘the size of Norfolk’ on collision course with South Georgia. Collapse of shelves would accelerate loss of Antarctic ice sheet and increase sea-level rise Published: 26 Aug 2020 . Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss. “[West Antarctic Ice Sheet] melting will affect everyone,” says Steig. But we are doing just that, even from our comfortable homes in temperate climes, and the ice in Antarctica is waking up and shifting in response. (See what a 10 billion ton chunk of ice looks like in this video). Secondly, and more importantly, ice is disappearing at a rate which far exceeds the upper bound of expectations projected by models built by the Intergovernmental Panel on Climate Change (IPCC). a climate canary? The United Nations also declared at the beginning of January that the past decade has been the hottest on record, and 2019 being the second-hottest year ever after 2016. This is "(57) WHAT Is Happening To Antarctica _! Scientists came to that conclusion after systematically computing gains and losses across 65 sectors of Antarctica where large glaciers - or glaciers flowing into an ice shelf - reach the sea. Required fields are marked *, I have read and agree to the Privacy Policy. But a warming planet has very clearly changed the way winds move around Antarctica—and that change is likely to continue, unless something drastic happens to slow or reverse the warming process. West Antarctica is … Records of wind strength and direction only went back until 1979. The expansion of sea ice, particularly in the Ross Sea, may be due to the strengthened westerlies pushing colder Antarctic surface water northwards. 10th Jun 2014. In the summer of 2017, we saw the largest iceberg ever — a piece of the Larsen C Ice Shelf — break off of Antarctica. The visit to Antarctica by Patriarch Kirill, the head of the Russian Orthodox Church, in February was the first sign of something unusual happening. But we are doing just that, even from our comfortable homes in temperate climes, and the ice in Antarctica is waking up and shifting in response. Copyright 2020 © Italics Magazine. In the panel’s 2014 assessment, its mid-range simulations (RCP4.5) suggested global sea-levels might rise by 53 cm by 2100. For some time now, I have heard stories of strange happening in Antarctica. Have we really grasped the social implications of these decisions? Follow. The world’s largest glacier is the Lambert Glacier is located in Antarctica. 5. By Retnik Beats:\r\r / On Dec 6, 2019 There are a lot of weird things happening in Antarctica. Antarctica is an important laboratory for research into the global impacts of the industrialized world. What’s happening in Antarctica won’t stay in Antarctica. Nerilie Abram, Australian National University; Matthew England, UNSW Australia, and Tessa Vance, University of Tasmania. Italics Magazine was born less than two years ago in Rome, from the idea of two friends who believed that Italy was lacking a complete, in-depth, across-the-board source of information in English. Due to this, the entire region contains many water ponds which never freeze over. Sea Spiders. If you’re not afraid of spiders yet, these fellows might change your mind if you’re “lucky” … More precisely, Earth’s great ice sheets, Greenland and Antarctica, are now losing mass six times faster than they were in the 1990s due to warming conditions. Their clipped reports are being reviewed by astonished superiors back in the home countries. Sometimes, those winds have weakened or reversed, which in turn causes changes in the ocean water that laps up against the ice in a way that caused the glaciers to melt. This has important implications for the future, for coastal flooding and erosion,” said Andrew Shepherd, professor at the University of Leeds and co-leader of the IMBIE project in a BBC interview. That’s not likely to happen anytime particularly soon, scientists think, but some parts of the ice sheet are particularly vulnerable, in danger of crossing a crucial “tipping point” if they retreat too far. In 2014, this iceberg, 20 miles wide, broke off the tongue of the glacier and floated away. The visit to Antarctica by Patriarch Kirill, the head of the Russian Orthodox Church, in February was the first sign of something unusual happening. Environment. It is the most southern of continents, quite at home on the bottom of our globe, as well as the coldest and most dry (classed as a desert!). The icy wastelands of Antarctica are infamously barren and inhospitable, making research very difficult. What is Happening in Antarctica? It is estimated to have a depth of 2,500 meters and covers a land area of 100 km wide and 400 km long. While the world frantically copes with the onslaught of the Sars-Cov-2 virus — the response to which has paralyzed our country and will soon do the same throughout Europe — we have overlooked two recent developments caused by that other curveball nature seems to be throwing at us: global warming. Those who are supposed to guard us should be forced to consider these and other questions seriously, lest we find ourselves facing Goliath, sling in hand, and wondering why we threw away the stones. Why call on countries to drastically cut carbon emissions when, in the near future, they will need to harness their productive capabilities to build barriers and seawalls around their coastlines and cities? What’s REALLY happening in Antarctica right now?. Antarctica is a very large continent, but it is still a mystery to most people. The ultimate cause of the wind patterns, they found, is human-caused climate change. The snow in Antartica is turning green. In the past decades, some glaciers in the region have been retreating shockingly quickly. This is especially possible thanks to our readers, who we hope to keep inspiring with our articles. The loss of polar ice may seem like an abstract concern, but it’s one that will affect all of us, no matter where we live, says glaciologist Michele Koppes. In the past, and even up to the early part of the record the scientists looked at in the 1920s, ice melted during warm phases and grew back during cold phases. Antarctica saw two record-high temperatures set between Feb. 6 and Feb.9, and that took a huge toll on the continent's ice, as seen in NASA images. This past week I read two scientific reports about planetary temperature changes. That's what the new research says is happening. That's what the new research says is happening. Though Shaefer cautioned that such a reading, taken on February 9, does not affect the general climate-change trend, he did clearly state that such a temperature had never been recorded in the history of human presence there. Scientists are sprinting to understand what is happening in West Antarctica as the planet warms around it. By Jeff. When they do, more warm water ends up near the edge of the ice sheet, which means more ice melts away. And if you want to see first-hand what’s happening with Antarctic sea ice and wildlife, well then come on down to Antarctica next year and we can have a great discussion over a glass of wine. Due to the coronavirus pandemic, we have ignored the latest discoveries in Antarctica that show we underestimated the rise in sea levels. The Antarctic ice sheet sat more or less stable in shape and size for many thousands of years. An international team of climate scientists and researchers working on a project called the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), has reviewed polar measurements acquired by observational satellites over the course of three decades, and in their comprehensive review, published in Nature in early March, they confirmed that the ice melting process is accelerating. Asked by Julianna. While some publications do a great job, writing about the latest news or focusing on specific areas of interest, we do believe that other kinds of quality insights are just as needed to better understand the complexity of a country that, very often, is only known abroad for the headlines that our politicians make, or for the classic touristic cliches. Running The Ice Marathon. Now, a team has unraveled evidence of that human influence. The lowest temperature recorded on our planet was taken here, at … Most of the glaciers in Antarctica are currently shrinking. Happening in Antarctica : Make a contribution ! “Today, the ice sheets contribute about a third of all sea-level rise, whereas during the 1990s their contribution was actually pretty small at about 5%. But while the science was clear that human influences on climate would affect the ice down the line, it has been hard to tell whether human-driven global warming has affected the melting already underway. Thank you. Stunning drone footage shows how an iceberg the size of Houston, Texas is holding on by a thread. Getty Images If it all melted away, global sea levels would rise by about 10 feet or more. One report concerned a space probe we launched years ago that is now circling the planet Mercury and sending back data. Antarctica is known as being one of the last places on Earth that humans discovered. Pine Island Glacier, in West Antarctica, is retreating quickly. (Read about the "tipping point" here). Michele Koppes. https://www.nationalgeographic.com/environment/2019/08/west-antarctic-glaciers-melting-human-influence.html, See what a 10 billion ton chunk of ice looks like in this video, See what the world would look like if all the ice melted away. The extra greenhouse gases humans have pumped into the atmosphere over the past few hundred years have changed the way heat moves around the planet so thoroughly that they’ve changed the shape of the basic wind patterns at the poles. Today’s pattern—with about equal west-flowing and east-flowing winds—means the whole region ends up quite a bit warmer than it was 100 years ago, when the wind flowed toward the west most of the time. About 10,000 years … The main purpose of these adventurers from the Bel Paese was in fact to study the evolution of global temperatures over the course of this quite brief period of geological history, and their findings are much awaited by their international colleagues, accustomed though they are to bad news. We wait for the next communication. Two new studies suggest West Antarctic ice melting is now occurring at a worrying level and one that is highly unusual compared to natural variability. This means that, while the effort is bigger, we can surely boast our independent and free editorial line.
