Canada pushes development as it takes over Arctic Council
Canada said Wednesday it will promote unprecedented industrial development in the far north as it takes over the helm of the Arctic Council, while activists called for a ban on oil drilling.
Scientists sound alarm at Arctic Ocean's rapid acidification
Scientists expressed alarm on Monday over the rapid acidification of the Arctic Ocean caused by carbon dioxide emissions, which could have dire consequences on the region's fragile ecosystem.
How the ice ages ended
A study of sediment cores collected from the deep ocean supports a new explanation for how glacier melting at the end of the ice ages led to the release of carbon dioxide from the ocean.
1000-year Antarctic Peninsula climate reconstruction provides new insight into accelerating ice melt
A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ...
Simulations reveal formation of some glassy materials like the setting of a bowl of gelatin
Gelatin sets by forming a solid matrix full of random, liquid-filled pores—much like a saturated sponge. It turns out that a similar process also happens in some metallic glasses, substances whose molecular ...
Summer melt season is getting longer on the Antarctic Peninsula, research shows
New research from the Antarctic Peninsula shows that the summer melt season has been getting longer over the last 60 years. Increased summer melting has been linked to the rapid break-up of ice shelves in the area and rising ...
Experiments demonstrate unusual melting and recrystallization behavior in one-dimensional electron crystals
(Phys.org) —The melting of ice is a familiar process: the ice gradually loses its crystalline structure and becomes a featureless puddle of liquid. Normally, no amount of further heating will bring back ...
The future of exploration starts with 3-D printing
(Phys.org) —The latest in cutting-edge manufacturing is already making a significant impact in the future of space exploration.
Team finds how the world's saltiest pond gets its salt
Antarctica's Don Juan Pond might be the unlikeliest body of water on Earth. Situated in the frigid McMurdo Dry Valleys, only the pond's high salt content—by far the highest of any body of water on the planet—keeps it ...
Melt ponds cause the Artic sea ice to melt more rapidly
The Arctic sea ice has not only declined over the past decade but has also become distinctly thinner and younger. Researchers are now observing mainly thin, first-year ice floes which are extensively covered ...
Research update: Atomic motions help determine temperatures inside Earth
(Phys.org)—In December 2011, Caltech mineral-physics expert Jennifer Jackson reported that she and a team of researchers had used diamond-anvil cells to compress tiny samples of iron—the main element of the e ...
Researchers team up with some 'locals' in Greenland to study rising sea levels
David Holland, a professor in NYU's Courant Institute of Mathematical Sciences, has been studying changes in the sea level off the coast of Greenland for years. His work involves collecting data on glacier formation, then ...
Climate—the hot topic in Doha
ESA joined international delegates in Doha, Qatar, to discuss how satellite observations show our planet's most sensitive areas reacting to climate change – and how this information is useful to the people living there.
UN chief urges faster response to global warming
(AP)—U.N. Secretary-General Ban Ki-moon on Tuesday urged governments to speed up talks to forge a joint response to global warming, describing it as an "existential challenge for the whole human race."
