Researchers say polar bears are victims in public war of words
Polar bears and Inuit communities have become victims in the public war of words on climate change and wildlife conservation, according to researchers from Britain and Canada.
Weakened 'polar vortex' blamed for N. American chill
The bitter chill gripping North America is a result of Arctic air that has spilled southwards, and global warming may be a cause, an expert said on Monday.
An icebreaker gets stuck in the ice, photos are used to mislead
As the saying goes, a picture is worth a thousand words, and by now you might have seen dramatic images of passengers on stranded icebreaker Akademik Shokalskiy being rescued by helicopter last Friday after becoming lodged in Antarctica sea ice on Christmas Eve. ...
New research sheds light on history of polar current
Research conducted by a team that included scientists from British Antarctic Survey reveals the ocean current moving around the South Pole flowed at much the same speed in the last ice age as it has done ...
Video: Mars 360: The North Pole
Enjoy views of the martian north pole from all angles in this new animation from ESA's Mars Express.
Scientist tries to predict rise in ocean levels
Columbia climatologist Maureen Raymo is trying to predict the planet's future by looking to its past.
Why is Antarctic sea ice growing?
Recently NASA reported that this year's maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year's record. ...
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?
Stronger winds explain puzzling growth of sea ice in Antarctica
(Phys.org) —Much attention is paid to melting sea ice in the Arctic. But less clear is the situation on the other side of the planet. Despite warmer air and oceans, there's more sea ice in Antarctica now ...
Tackling an Ice Age mystery
In the northern hemisphere, ice sheets ebb and flow in 100,000-year cycles, driven by varying amounts of sunlight falling on Earth's surface as its orbit and orientation toward the sun changes. But astronomical variations ...
The paradox of polar ice sheet formation solved
The beginning of the last glacial period was characterized in the Northern hemisphere by major accumulation of snow at high latitudes and the formation of a huge polar ice sheet. For climatologists this was ...
Floe by floe, the ice surrenders its secrets
Bowhead and minke whale sightings, extensive ice floe measurements and the successful retrieval of important moored instruments are among the successes of a multinational team of ice engineering researchers ...
Earth orbit changes key to Antarctic warming that ended last ice age
For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher ...
Mars: What lies beneath
There is much more to Mars than meets the eye. By using the radar on Mars Express, we can see several kilometres below the surface to see what lies beneath.
