Rift Speeds Up Across Antarctic Ice Shelf

Rift Speeds Up Across Antarctic Ice Shelf

As the sun reemerged over the Antarctic horizon in August after the long, dark austral winter, satellites could once again peer at a rift that has been wending its way across the white expanse of the Larsen C Ice Shelf on the eastern side of the Antarctic Peninsula. To the surprise of scientists, satellite images revealed that the fissure had … Read More

Greenland is Losing More Ice Than Scientists Thought

Greenland is Losing More Ice Than Scientists Thought

Bad news keeps flowing for the icy landscapes of the world. Rising temperatures are melting ice and sending it to the ocean, a process that is pushing sea levels higher and altering the landscape at both poles. The latest news comes from Greenland, where researchers have used high-tech satellite and GPS measurements to see how much mass the ice … Read More

These Images Show Near-Record Low 2016 Arctic Sea Ice

Arctic sea ice is one of the grandaddy’s of climate indicators. And this grandaddy isn’t doing so good these days. Ice is disappearing at a quickening clip as rapidly warming air and water eats away at the briny, frozen mantle on the top of the planet. In the nearly four decades of satellite monitoring, sea ice has disappeared at a clip of 13.4 … Read More

Scientists Are Racing to Unravel an Ice Avalanche Mystery

Scientists Are Racing to Unravel an Ice Avalanche Mystery

In July, one of the largest ice avalanches ever recorded ripped through a remote area of Tibet. Scientists are now working in the region to understand what caused such a massive chunk of ice to break off a glacier and wreak havoc on the landscape and people living in the region. There are signs climate change could have played a role in weakening … Read More

Despite Major Melt, Arctic Sea Ice Will Miss Record Low

Despite Major Melt, Arctic Sea Ice Will Miss Record Low

As the sun begins its seasonal descent in the Arctic sky and temperatures drop, the summer melt of sea ice is slowing down. In the next few weeks, the span of the Arctic Ocean covered by ice will reach its annual low. But despite beginning the summer at unprecedentedly low levels, this year’s minimum won’t break the stunning record of 2012, expert… Read More

Climate Change Could Put Tiny Krill at Big Risk

Climate Change Could Put Tiny Krill at Big Risk

They may be small, but krill — tiny, shrimp-like creatures — play a big role in the Antarctic food chain. As climate change warms the Southern Ocean and alters sea ice patterns, though, the area of Antarctic water suitable for krill to hatch and grow could drop precipitously, a new study finds. Most Antarctic krill are found in an area from the … Read More

This Is What the Ice-Free Northwest Passage Looks Like

This Is What the Ice-Free Northwest Passage Looks Like

An ice-free Northwest Passage was once the stuff of legend. But it’s now becoming the norm thanks to global warming, and commercial freighters to luxury cruise ships are racing to turn a profit off the newest frontier on earth. An image published by NASA Earth Observatory shows a nearly ice-free path from the North Atlantic to the Pacific… Read More

Greenland Melt Could Expose Hazardous Cold War Waste

Greenland Melt Could Expose Hazardous Cold War Waste

When the U.S. military abandoned Camp Century, a complex of tunnels dug into the ice of northwest Greenland, in the mid-1960s, they left behind thousands of tons of waste, including hazardous radioactive and chemical materials. They expected the detritus would be safely entombed in the ice sheet for tens of thousands of years, buried ever deeper… Read More
