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.
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.
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 ...
Iceland rises as its glaciers melt from climate change
The Earth's crust under Iceland is rebounding as global warming melts the island's great ice caps, a University of Arizona-led team reports in an upcoming issue of Geophysical Research Letters.
Erratic as normal: Arctic sea ice loss expected to be bumpy in the short term
Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change—and rapid change—at ...
Gully patterns document Martian climate cycles
Geologists from Brown University have found new evidence that glacier-like ice deposits advanced and retreated multiple times in the midlatitude regions of Mars in the relatively recent past.
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 ...
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, ...
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.
The heat is on; NOAA, NASA say 2014 warmest year on record
For the third time in a decade, the globe sizzled to the hottest year on record, federal scientists announced Friday.
Measuring the impact of light-absorbing particles on Earth's snowpack, glaciers, and ice cover
When dust, soot and other black or dark-colored particles emitted through pollution are deposited in snow and ice, they increase melting. Pacific Northwest National Laboratory led a comprehensive, state-of-the-science ...
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.
Distinctive sounds announce iceberg births
Underwater sounds can be used to detect different ways glaciers lose ice as they flow into the ocean, giving scientists new insight into these poorly understood events, according to new research.
