A major glacier is undermined from below Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say"”a process that feeds back into the ongoing rise in global sea levels. The glacier is currently sliding into the sea at a clip of four...

Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East Antarctica larger than Texas. The map reveals some of the largest fjords or ice cut channels on Earth, providing important insights into the history of ice in Antarctica. The data will also help computer modelers improve their simulations of the past...

With an estimated 34,000 square miles of ice, an area about the size of Maine, Alaska's multitude of glaciers have a global impact. Anthony Arendt, an assistant research professor at the University of Alaska Fairbanks Geophysical Institute, has outlined the complexity and influence of Alaska glaciers in last week's issue of the journal Science. In his article, Arendt explains the importance of integrating field observations and more precise glacier simulation models. "We have used satellites...

A team of scientists from the University of Sheffield and Bangor University have used a computer climate model to study how freshwater entering the oceans at the end of the penultimate Ice Age 140,000 years ago affected the parts of the ocean currents that control climate. A paper based on the research, co-authored by Professor Grant Bigg, Head of the University of Sheffield's Department of Geography, his PhD student Clare Green, and Dr Mattias Green, a Senior Research fellow at Bangor...

According to a new study, melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought. There are bout 30,000 islands within the 550,000-square-mile Canadian Arctic Archipelago.  The study found that between 2004 and 2009, the region lost the equivalent of three-quarters of the water in Lake Erie. Alex Gardner, a research fellow in the Department of Atmospheric, Oceanic and Space Sciences at the University of...

Loss of glaciers and snowpack due to climate warming in alpine regions is putting pressure on a rare aquatic insect, the meltwater stonefly, according to a study recently released in Climatic Change Letters. In the study, scientists with the U.S. Geological Survey, the University of Montana, U.S. Fish and Wildlife Service and National Park Service illustrate that alpine aquatic insects can be good early warning indicators of climate warming in mountain ecosystems. The glaciers in Glacier...

New research, published Sunday in the journal Nature Geoscience, highlights San Rafael Glacier in Patagonia, which has retreated about 5 miles since the peak of the Little Ice Age, BBC News reports. Glaciers have lost volume on average "10 to 100 times faster" in the last 30 years. Sea levels are rising faster now than at any time in the last 350 years and melting glaciers are a large reason for that, according to the study by Universities at Aberystwyth, Exeter and Stockholm who looked at...

"Recent scientific studies indicate that between June 1983 and August 2006, a glacier on Peru's Huaytapallana Mountain has lost 50 percent of its surface ice," Erasmo Meza, manager of natural resources and the environment in the central Andean region of Junin, told the official Andina news agency. Losing the ice in just 23 years, officials warned of concerns of climate change's growing threat to fresh water resources in the Andes mountains. Meza continued, telling AFP the 1.9 square miles of...

Glacier National Park is located in the American state of Montana, south of the Canadian borders of British Columbia and Alberta. The park contains one million acres of varying landscape with a wide range of plant and animal life. It holds two mountain ranges, over 130 discovered and named lakes, and 16,000 square miles of protected unspoiled ecosystem known as the Crown of the Continent Ecosystem. The history of human presence in the Glacier National Park area is thought to begin about...

Glacier Bay National Park and Preserve is located in the Alaska panhandle, west of the city of Juneau. The establishment of the park first began in 1925, when Calvin Coolidge signed the bill that would make the Glacier Bay area a national monument. After an expansion occurred in 1978 by President Jimmy Carter, the park increased in size by 523,000 acres under the Alaska National Interest Lands Conservation Act (ANILCA). This act helped expand the park again in 1980, while it was in the...
