Odd Rifts in Antarctic Ice Could Mean ‘Sayonara, Glacier’

Odd Rifts in Antarctic Ice Could Mean ‘Sayonara, Glacier’

In August of 2015, a large iceberg broke off from the floating section of Antarctica’s massive Pine Island Glacier. While such an event is part of the natural life cycle of glaciers, this one was precipitated by an unusual rift in the middle of the ice that could point to a new mechanism for the collapse of this and potentially other glaciers … Read More

World’s New Marine Protected Area is a Big Climate Win

World’s New Marine Protected Area is a Big Climate Win

The creatures of the Southern Ocean just got a lot more space to roam freely. On Thursday, 24 countries and the European Union agreed to set aside a 600,000-square-mile swath of ocean — roughly twice the size of Texas — off the coast of Antarctica as a marine protected area. It’s taken years of negotiations to get to this point, but the end… Read More

Warm Ocean Water Takes Toll on Antarctica’s Glaciers

Warm Ocean Water Takes Toll on Antarctica’s Glaciers

It has become increasingly clear in recent years that ocean waters are eating away at the undersides of the ice shelves that fringe Antarctica and buttress its many glaciers. A new study released Tuesday has found that hundreds of feet of ice have been lost from the bottoms of a few of these ice shelves and glaciers in a region of the continent… Read More

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

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

Antarctic Peninsula Has Cooled, but Warming Will Win

Antarctic Peninsula Has Cooled, but Warming Will Win

For most of the latter half of the 20th century, the Antarctic Peninsula was one of the fastest-warming places on the planet, with serious repercussions for the local environment, including the spectacular disintegration of a millennia-old ice shelf, and global sea level rise. But a new study detailed Thursday in the journal Nature suggests … Read More

Oceans Eating Away at Yet Another Part of Antarctica

Oceans Eating Away at Yet Another Part of Antarctica

The Antarctic Peninsula is one of the fastest warming spots on the planet, and it was thought that the rising air temperature was driving the melt of the glaciers along its fringes. But it is actually warm ocean waters that are eating away at the ice along part of its western side, a group of scientists reported Thursday in the journal Science. The… Read More

Antarctic CO2 Hit 400 PPM For First Time in 4 Million Years

Antarctic CO2 Hit 400 PPM For First Time in 4 Million Years

We’re officially living in a new world. Carbon dioxide has been steadily rising since the start of the Industrial Revolution, setting a new high year after year. There’s a notable new entry to the record books. The last station on Earth without a 400 parts per million (ppm) reading has reached it. A little 400 ppm history. Three years ago, the … Read More
