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 […]
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 […]
Rising temperatures in the air and the water surrounding Greenland are melting its massive ice sheet at a faster rate than anytime in the last 12 millennia, according to a new study published Wednesday in the journal Nature. The study, Rate of mass loss from the Greenland Ice Sheet will exceed Holocene values this century, […]
Antarctica‘s Thwaites Glacier has been called the “Doomsday Glacier.” Thwaites and its neighbor, the Pine Island Glacier, are among those in West Antarctica most influenced by the climate crisis. If they melted, they could destabilize the entire West Antarctic Ice Sheet, which has the potential to contribute about 10 feet to global sea level rise. […]
Antarctica and Greenland‘s ice sheets are currently melting at a pace consistent with worst-case-scenario predictions for sea level rise, with serious consequences for coastal communities and the reliability of climate models. A paper published in Nature Climate Change Monday compared the latest satellite observations of polar ice melt with the predictions outlined in the Intergovernmental […]
The Earth has lost 28 trillion tonnes (approximately 31 trillion U.S. tons) of ice in just 23 years, and the climate crisis is largely to blame. The finding comes in a review paper published in The Cryosphere this month that used satellite data and numerical modelling to calculate all the ice that melted worldwide between […]
New satellite images have revealed 11 new throngs of emperor penguin colonies, lifting the number of known emperor penguin colonies by 20 percent and their total population by 5 to 10 percent, according to The Guardian. “The [new colonies] are an exciting discovery,” said Peter Fretwell, at the British Antarctic Survey (BAS), who led the […]
By Shaun Brooks and Julia Jabour Australia wants to build a 2.7-kilometre concrete runway in Antarctica, the world’s biggest natural reserve. The plan, if approved, would have the largest footprint of any project in the continent’s history. The runway is part of an aerodrome to be constructed near Davis Station, one of Australia’s three permanent […]
