Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

The warming of the world’s oceans is penetrating radar. They discovered two causing a glacier the size of California in massive undersea valleys beneath the East Antarctica to melt, and scientists fear ice sheet, one of which is 3 miles wide, its collapse could eventually cause global Those canyons allow warm, salty water sea levels to rise by as much […]

Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of Arctic soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil. Soil in the Arctic has for thousands of years gathered large quantities […]

It’s official: There really was a giant, flightless bird with a head the size of a horse’s wandering about in the winter twilight of the high Arctic some 53 million years ago. The confirmation comes from a new study by researchers from the Chinese Academy of Sciences in Beijing and the University of Colorado Boulder that describes the first and […]

A new NASA study on the Antarctic Ice Sheet says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that […]

On Dec 1st 2016, 86 year old former astronaut Buzz Aldrin was evacuated from the South Pole after his health deteriorated during a trip with a tourist group visiting the Amundsen-Scott South Pole Station. After being transported to Christchurch, the Antarctic program’s logistics hub in New Zealand, Aldrin was transferred to a local medical facility, where he was responding well […]
