Study raises concerns over big, rapidly thinning Antarctic glacier
2015-03-18 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
CNN: Scientists have raised concerns about a large, rapidly thinning glacier in Antarctica, warning it could contribute significantly to rising sea levels. They say they've discovered two openings that could channel warm seawater to the base of the huge Totten Glacier and bring the threat of potentially disastrous melting. The glacier is bigger and thinning faster than all the others in East Antarctica. It contains enough ice to raise the global sea level by at least 11 feet (3.4 meters), according...

A second giant blob of Antarctic ice is getting ready drown us
2015-03-17 19:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Remember when we found out last year that the West Antarctic ice sheet had started to collapse, that the collapse more or less cant be stopped, and that it will eventually result in 10 to 15 feet of sea-level rise? Now we have some more bad news of that caliber. An enormous glacier, one on the other side of the continent from the ailing ice sheet, is doing pretty much the same thing, researchers have discovered. Chris Mooney reports for The Washington Post: The findings about East Antarctica...
How Earth's Orbit Affects Antarctic Ice Caps

Nature World: The Earth's orbit, while a concept that is light-years away, is hitting close to home, affecting the stability of Eastern Antarctic ice caps, according to a new study. Sea levels in Antarctica are rising or falling by as much as dozens of meters due to simple changes in the Earth's orbit around the Sun. And the site that is most affected is the continental fringe of Wilkes Land in East Antarctica. Analyses of seabed sediments dating back 2.2 to 4.3 million years ago show that natural climatic...
Underwater Drones Map Algae Beneath Antarctic Ice

Live Science: Although the surface of Antarctica is almost completely white, a field of green and brown algae clings to the underside of the sea ice around the frozen continent. Previously, this underwater forest of algae was accessible only to marine creatures or specially trained divers. But now, researchers are using pioneering drones to scout out and map the miles of algae mats. The Antarctic algae begin growing in early spring and rely on the small amount of sunlight that penetrates the ice to survive....

Climate change could be happening 2,400 feet under Antarctic ice
2015-01-19 13:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: In case you missed out on the bad news du jour, let me both enlighten and disturb you (the primary job description here at Grist): The world is now experiencing skyrocketing temperatures and ocean death spirals, all while humans are sucking the living daylights out of the planet. And now, scientists have uncovered data that suggests climate change could be affecting a place where humans have never even set foot: 2,400 feet below Antarctic ice. We`ve known for a while that the warming planet is...
