Another Melting Antarctic Glacier
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 […]
Read moreArctic soil frost affects greenhouse gas emissions
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 […]

Research shows there may be an entire world underneath Antarctica’s ice-free Dry Valleys, which on the surface may seem hostile to life. Below the surface lies rivers of liquid salt water which flow into subsurface lakes, every drop of which could be swarming with microbial life. One of Antarctica’s most unique features, the briny, rusty-red colored Blood Falls, could possibly […]
