The number of Antarctic sightseers doubled over the past decade, reaching nearly 75,000 in 2019. New research finds the soot, or black carbon, from these visits is causing an extra inch of snowpack shrinkage each year. “It really makes us question, is our presence really needed?” Alia Khan, a glaciologist and study author asked NPR. […]
The Pine Island Glacier is currently Antarctica‘s greatest contributor to sea level rise, and, now, a new study warns that it could be closer to collapse than previously thought. The research, published in Science Advances Friday, found that the vulnerable glacier had sped up by 12 percent over the last three years as the ice […]
Yesterday was World Oceans Day, and this year National Geographic made the celebration extra special — by recognizing a whole new ocean. Since National Geographic began making maps in 1915, it has officially acknowledged four oceans: the Atlantic, Pacific, Indian and Arctic. Now, it is adding the Southern Ocean, the body of water that surrounds […]
A massive chunk of ice broke off of Antarctica this month, and it is now the largest iceberg in the world. The iceberg, known as A-76, was first spotted by a British Antarctic Survey researcher May 13. It was then confirmed by the U.S. National Ice Center (USNIC) the next day using images from the […]
By Jake Johnson A new study published Wednesday in the journal Nature warns that if the world’s governments fail to meet warming targets set by the Paris climate accord, sea level rise from the melting of the Antarctic ice sheet will accelerate at a “rapid and unstoppable” rate in the coming decades. Authored by researchers […]
By Brett Wilkins Researchers warned of the need for urgent climate action as a study published Wednesday revealed that the world’s mountain glaciers are melting at an unprecedented pace, with glacial thinning rates outside Antarctica and Greenland doubling this century. For the first time ever, researchers analyzed three-dimensional satellite measurements of the world’s approximately 220,000 […]
The world’s largest iceberg could collide with South Georgia Island, posing a major risk to the wildlife that call it home. The iceberg, dubbed A68a, broke off from Antarctica‘s Larsen C ice shelf in 2017. After three years at sea, it is now approaching South Georgia Island, where it could run aground. This would block […]
By Peter A. Kloess Picture Antarctica today and what comes to mind? Large ice floes bobbing in the Southern Ocean? Maybe a remote outpost populated with scientists from around the world? Or perhaps colonies of penguins puttering amid vast open tracts of snow? Fossils from Seymour Island, just off the Antarctic Peninsula, are painting a […]
The hole in the ozone layer over Antarctica is one of the largest and deepest in the past 15 years, the World Meteorological Organization (WMO) said Tuesday. The ozone hole over Antarctica usually starts to grow in August and reaches its peak in October, The Associated Press explained. This year, it peaked at 24 million […]
