Mega-canyon discovered beneath Greenland ice sheet
A previously unknown canyon hidden beneath two kilometers of ice covering Greenland has been discovered by a group of scientists, led by a team from the University of Bristol.
'Cascade of events' caused sudden explosion of animal life
The explosion of animal life on Earth around 520 million years ago was the result of a combination of interlinked factors rather than a single underlying cause, according to a new study.
Video from polar bear's neck cam shows life on ice
The first video of life on Arctic sea ice from a polar bear point of view has been released by the U.S. Geological Survey.
Unprecedented rate and scale of ocean acidification found in the Arctic
Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a proces ...
Global warming: The conversation we need to have
We all know the earth's climate is changing. The effects are inescapable no matter where we live. Here in New England, some changes are subtle (more humidity, consistently warmer nights), dramatic (more intense ...
Arctic ice shrinking in volume, too, ESA reports
Arctic sea ice, which has been declining in area by unprecedented amounts in summer, is also falling in volume, the European Space Agency (ESA) said on Wednesday.
Climate change: Polar bears change to diet with higher contaminant loads
Researchers expect the climate to become warmer in the future and predict that climate change will have a significant impact on the Arctic. How will a warming Arctic affect the polar bears?
Arctic warmth unprecedented in 44,000 years, reveals ancient moss
When the temperature rises on Baffin Island, in the Canadian high Arctic, ancient Polytrichum mosses, trapped beneath the ice for thousands of years, are exposed. Using radiocarbon dating, new research in Geophysical Research Le ...
NASA to investigate climate impacts of Arctic sea ice loss
A new NASA field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate. The Arctic Radiation IceBridge Sea and Ice Experiment (ARISE) will conduct ...
Ex-NASA expert issues call for climate solutions
Longtime NASA expert James Hansen has issued a call for new approaches to stop global warming, saying solutions are needed and that currently accepted targets are too dangerous.
Facebook starts first servers outside the US (Update)
Facebook on Wednesday started processing data through its first server farm outside the United States, on the edge of the Arctic Circle in Sweden.
Alaska tundra shows surprising resilience after unprecedented fire
Despite the size and severity of the massive 2007 Anaktuvuk River fire on Alaska's North Slope, much of the arctic vegetation has recovered and the tundra is likely to return to its pre-fire condition according ...
Is global warming hiding underwater?
Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result ...
Study shows global sea ice diminishing, despite Antarctic gains
Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new NASA study finds. As a whole, the planet has been shedding sea ice at an average annual rate ...
