Scientists believe they have found the world's oldest ice sheet, which will provide information on future climate change.
In a few weeks, NASA's Operation IceBridge will take to the skies for another busy season of monitoring ice sheets, glaciers and sea ice from above. This year, the mission will be stationed in Antarctica for the first time, enabling scientists to conduct longer flights, and explore areas of the icy...
A block of countries has issued a joint call for the creation of marine reserves in Antarctica.
If greenhouse emissions continue their steady escalation, temperatures across most of the earth will rise to levels with no recorded precedent by the middle of this century, researchers said Wednesday.
Deep furrows on Antarctica's floating ice shelves mark arch-shaped channels melted out under the ice. Thinner ice floats lower, and researchers can read the corrugated surface topography like a map that mirrors what lies beneath.
The global climate has already changed in many ways that are unprecedented in the past hundreds or thousands of years, the world's scientists and governments concluded in the new report from the Intergovernmental Panel on Climate Change.
Recent warming of the Greenland Sea Deep Water is about ten times higher than warming rates estimated for the global ocean. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently published these findings in the journal Geophysical Research Letters.
The Arctic's summer sea ice is set to nearly vanish in less than 40 years, according to the final draft of a sweeping UN climate change report that sharply revises past estimates of how fast the icy north is melting.
The volume of sea ice in the Arctic hit a new low this past winter, according to observations from the European Space Agency's (Esa) Cryosat mission.
After a record-breaking decline in the extent of summer sea ice on the Arctic Ocean last year, this year's minimum has returned to levels that more closely track the long-term rate of decline that scientists have measured for at least 34 years.
Ice in Antarctica and Greenland is disappearing faster and may drive sea levels higher than predicted this century, according to leaked United Nations documents.
The results of research conducted by professors at UC Santa Barbara and colleagues mark the beginning of a new paradigm for our understanding of the history of Earth's great global ice sheets. The research shows that, contrary to the popularly held scientific view, an ice sheet on West Antarctica...
Data from a NASA airborne science mission reveals evidence of a large and previously unknown canyon hidden under a mile of Greenland ice.
The LC-130 Hercules flew low over the ice sheet in a tight grid pattern, Teflon-coated landing skis barely 300 metres above the soft upper layer of snow. At the rear of the plane, scientists clustered round a monitor displaying a regular pattern of dark red waves generated by a radar signal.
The effects of increased melting on the future motion of and sea-level contribution from Greenland’s massive ice sheet are not quite as dire as previously thought, according to a new study from an international team of researchers.
