Greenland Glacier Loses An Ice Island Twice The Size Of Manhattan
2012-07-18 07:11:16

redOrbit Staff & Wire Reports - Your Universe Online Andreas Muenchow, associate professor of physical ocean science and engineering in University of Delaware´s College of Earth, Ocean, and Environment, reports the calving of an island two times the size of Manhattan on July 16, 2012, in his “Icy Seas” blog. Muenchow credits Trudy Wohleben of the Canadian Ice Service for first noticing the fracture. MODIS, the Moderate Resolution Imaging Spectroradiometer aboard...

Resting in the Karakoram Range between northern Pakistan and western China, the Karakoram glaciers are stumping scientists. Unlike most mountain glaciers, the Karakoram glaciers, which account for 3 percent of the total ice-covered area in the world, excluding Greenland and Antarctica, are not shrinking. On the contrary, a team of French glaciologists has recently confirmed that these glaciers on average have remained stable or may have even grown slightly in recent years. Although all...

Deglaciation Data Opens Door For Earlier First Americans Migration
2012-06-25 04:06:21

A new study of lake sediment cores from Sanak Island in the western Gulf of Alaska suggests that deglaciation there from the last Ice Age took place as much as 1,500 to 2,000 years earlier than previously thought, opening the door for earlier coastal migration models for the Americas. The Sanak Island Biocomplexity Project, funded by the National Science Foundation, also concluded that the maximum thickness of the ice sheet in the Sanak Island region during the last glacial maximum was 70...

80-Year-Old Photos Aid In Greenland Ice Melt Study
2012-05-30 09:11:47

Researchers from Denmark´s University of Copenhagen have gained new insight into the loss of ice mass in Greenland´s glaciers thanks to a chance discovery of 80-year-old photo plates discovered in a Danish basement. It is often difficult for scientists to assess the scale and speed of Arctic ice melt, but the extremely rare photos provide them with a more accurate picture. Greenland´s ice was rapidly melting in the 1930s, followed by a cooling period in middle of the 20th...

Antarctica Ice Sheet May Begin Melting Rapidly By Century's End
2012-05-09 13:58:16

Scientists report in the journal Nature that an Antarctic ice sheet may start to melt rapidly in this century. The finding, made by climate researchers of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, refute a widely believed theory that ice shelves in the Weddell Sea would not be affected by global warming due to the peripheral location of the sea. "The Weddell Sea was not really on the screen because we all thought that unlike the Amundsen...

Greenland Glacier Acceleration Levels Less Than Originally Feared
2012-05-04 06:55:11

Some of Greenland's glaciers are moving approximately 30% faster than they were a decade ago, contributing to the rising sea level but not reaching worst-case speed levels that experts once feared, a new study published in Friday's edition of the journal Science has discovered. According to Reuters reporter Deborah Zabarenko, researchers at the University of Washington (UW) and Ohio State University (OSU) studied satellite data from 2000 to 2011. They focused on more than 200 glaciers and...

Image 1 - Warm Ocean Currents Cause Ice Loss In Antarctica
2012-04-26 04:55:01

Lee Rannals for RedOrbit.com [ Watch the Video ] An international team of scientists reported in the journal Nature on Thursday that warm ocean currents are the culprit behind recent ice loss in Antarctica. The team, lead by British Antarctic Survey, used 4.5 million measurements made by a laser instrument mounted on NASA's ICESat satellite to map the changing thickness of Antarctica's floating ice shelves. Of the 54 ice shelves they mapped, they revealed that 20 are melting...

State Of Himalayan Glaciers Less Alarming Than Feared
2012-04-20 08:21:58

Ever since the false prognoses of the Intergovernmental Panel on Climate Change (IPCC), the Himalayan glaciers have been a focus of public and scientific debate. The gaps in our knowledge of glaciers in the Himalayan region have hindered accurate statements and prognoses. An international team of researchers headed by glaciologists from the University of Zurich and with the involvement of scientists from Geneva now outlines the current state of knowledge of glaciers in the Himalayas in a...

CU Research Shows Warming Climate Threatens Ecology At Mountain Research Site West Of Boulder
2012-04-19 07:42:15

A series of papers published this month on ecological changes at 26 global research sites -- including one administered by the University of Colorado Boulder in the high mountains west of the city -- indicates that ecosystems dependent on seasonal snow and ice are the most sensitive to changes in climate. The six papers appeared in the April issue of the journal BioScience. The papers were tied to data gathered at sites in North America, Puerto Rico, the island of Moorea near Tahiti, and...

Greenland Slipping Away
2012-04-17 05:03:44

Massive releases of meltwater from surface lakes may be causing Greenland to slide ever faster into the ocean, according to a new study by the University of Colorado Boulder-based Cooperative Institute for Research in Environmental Sciences (CIRES). Researchers say these actions could increase sea-level rise, having a direct impact on coastal communities. “This is the first evidence that Greenland´s ℠supraglacial´ lakes have responded to recent increases in surface...

Glacier National Park (US)
2013-03-19 14:40:11

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
2013-03-19 13:07:23

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...
