Retreating Antarctic Glacier Could Raise Sea Levels 5 Feet

Retreating Antarctic Glacier Could Raise Sea Levels 5 Feet

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 […]

    This Penguin Colony Has Fallen by 77% on Antarctic Islands

    This Penguin Colony Has Fallen by 77% on Antarctic Islands

    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” […]

    Antarctica Breaks Its Hottest Recorded Temperature

    Antarctica Breaks Its Hottest Recorded Temperature

    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 […]

    World’s Largest Iceberg Headed for Open Water

    World’s Largest Iceberg Headed for Open Water

    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 […]

    Record Warm Water Measured Beneath Antarctica’s ‘Doomsday’ Glacier

    Record Warm Water Measured Beneath Antarctica’s ‘Doomsday’ Glacier

    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 […]

    5 Things to Know About Earth’s Warming Oceans

    5 Things to Know About Earth’s Warming Oceans

    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 […]

    Ozone-Depleting Substances May Have Driven Arctic Warming, Study Finds

    Ozone-Depleting Substances May Have Driven Arctic Warming, Study Finds

    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 […]
