Warm ocean melting East Antarctica's largest glacier
The largest glacier in East Antarctica, containing ice equivalent to a six-metre (20-foot) rise in global sea levels, is melting due to warm ocean water, Australian scientists said on Monday.
A 3-D view of the Greenland Ice Sheet opens window on ice history
Scientists using ice-penetrating radar data collected by NASA's Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening ...
Two lakes beneath the ice in Greenland, gone within weeks
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly drained away.
Scientists drilling first deep ice core at the South Pole
This winter, when many people's imaginations were fixed on the North Pole, a small group of scientists has been working on the other side of the planet. In round-the-clock daylight and frigid temperatures, ...
Acceleration in sea level rise far larger than initially thought, study shows
The acceleration in global sea level from the 20th century to the last two decades has been significantly larger than scientists previously thought, according to a new Harvard study.
Melting glaciers have big carbon impact, study shows
As the Earth warms and glaciers all over the world begin to melt, researchers and public policy experts have focused largely on how all of that extra water will contribute to sea level rise.
Study shows how meltwater on Greenland's ice sheet contribute to rising sea levels
As the largest single chunk of melting snow and ice in the world, the massive ice sheet that covers about 80 percent of Greenland is recognized as the biggest potential contributor to rising sea levels due ...
Antarctic drilling team is first to bore through hundreds of meters of ice to where ice sheet, ocean and land converge
Using a specially designed hot-water drill to cleanly bore through a half mile of ice, a National Science Foundation (NSF)-funded team of researchers has become the first ever to reach and sample the "grounding ...
UNL drillers help make new Antarctic discoveries
Using a hot-water drill and an underwater robotic vehicle designed, built and operated by a University of Nebraska-Lincoln engineering team, scientists have made new discoveries about Antarctica's geology ...
Greenland Ice: The warmer it gets the faster it melts
Melting of glacial ice will probably raise sea level around the globe, but how fast this melting will happen is uncertain. In the case of the Greenland Ice Sheet, the more temperatures increase, the faster ...
Giant atmospheric rivers add mass to Antarctica's ice sheet
Extreme weather phenomena called atmospheric rivers were behind intense snowstorms recorded in 2009 and 2011 in East Antarctica. The resulting snow accumulation partly offset recent ice loss from the Antarctic ...
On a tropical island, fossils reveal the past—and possible future—of polar ice
The balmy islands of Seychelles couldn't feel farther from Antarctica, but their fossil corals could reveal much about the fate of polar ice sheets.
