Antarctica‘s Denman Canyon is the deepest gorge on the Earth’s surface, and, if the ice inside it melted, it could raise sea levels by almost five feet. Now, research published in Geophysical Research Letters Monday looked at how close that might be to happening and found that the glacier had retreated five kilometers (approximately three […]
The climate crisis is taking a toll on Antarctica‘s chinstrap penguins. Scientists on a Greenpeace expedition to Antarctica found that the penguins’ numbers were falling, with one colony decreasing by 77 percent in nearly 50 years. This is especially surprising because, up until now, the chinstrap penguin has been considered a species of “least concern” […]
T-shirt weather in Antarctica? The continent just measured its hottest temperature on record at a balmy nearly 65 degrees Fahrenheit. The reading was taken by Argentina’s National Meteorological Service at the country’s Esperanza research station, AFP reported. The thermometer climbed to 18.3 degrees Celsius (approximately 64.9 degrees Fahrenheit) around noon on Thursday, beating Antarctica’s previous […]
The world’s largest iceberg, which broke free from Antarctica in 2017, is about to escape the boundaries of the continent’s perennial sea ice and make its way into the open ocean, according to the BBC. The massive iceberg, named A68, weighed up to a trillion tons, and measured 2,300 square miles, when it broke off […]
Scientists have discovered record warm water beneath Antarctica‘s “doomsday glacier” for the first time, leading to concerns for the glacier whose collapse could contribute nearly a meter (approximately 3 feet) to global sea level rise. The findings are part of the International Thwaites Glacier Collaboration — a UK and U.S.-led research expedition to better understand […]
By Douglas Broom Endurance swimmer and UN Patron of the Oceans Lewis Pugh has completed a 1 kilometer swim under the East Antarctic ice shelf. The feat was part of his campaign to secure a series of protected zones in the seas around the continent. He chose the 200th anniversary of the discovery of Antarctica […]
By Tara Lohan Part of Joellen Russell’s job is to help illuminate the deep darkness — to shine a light on what’s happening beneath the surface of the ocean. And it’s one of the most important jobs in the world right now. Russell is a professor of biogeochemical dynamics at the University of Arizona. From […]
By Dan Morgan Antarctica is the remotest part of the world, but it is a hub of scientific discovery, international diplomacy and environmental change. It was officially discovered 200 years ago, on Jan. 27, 1820, when members of a Russian expedition sighted land in what is now known as the Fimbul Ice Shelf on the […]
The world awakened to the hole in the ozone layer in 1985, which scientists attributed it to ozone-depleting substances. Two years later, in Montreal, the world agreed to ban the halogen compounds causing the massive hole over Antarctica. Research now shows that those chemicals didn’t just cut a hole in the ozone layer, they also […]
