Bad News Keeps Flowing From Antarctica

Bad News Keeps Flowing From Antarctica

The massive shelves of ice that ring Antarctica have been shrinking over the past couple of decades, and that could have grave implications for sea level rise. It’s not the ice shelves themselves that pose a problem: they’re mostly afloat, so when they melt or dump massive icebergs, it doesn’t affect water levels any more than melting ice cubes … Read More

The ABCs of Antarctic Ice Shelf Melting

The ABCs of Antarctic Ice Shelf Melting

January 1995 marked a seminal moment in modern Antarctic history, with the crumbling of the Larsen A ice shelf, a floating plain of ice fed by glaciers on the Antarctic Peninsula. Less than a decade later, its southern neighbor, the Larsen B ice shelf, disintegrated, stunning polar scientists. After the spectacular collapses of Larsen A and B… Read More

Antarctica’s Record High Temp Bodes Ill for Ice

Antarctica’s Record High Temp Bodes Ill for Ice

The Antarctic Peninsula is one of the fastest warming spots on the planet, but in recent days, a stubborn weather pattern sent temperatures skyrocketing there, setting a record high for the continent. While the event that set the mercury soaring — called a Chinook, or foehn wind — isn’t unusual for the region, it does seem to be increasing with… Read More

Antarctica’s Icy ‘Doorstops’ Thin; Rising Seas At Risk

Antarctica’s Icy ‘Doorstops’ Thin; Rising Seas At Risk

Over the past two decades, the massive platforms of floating ice that dot the coast of Antarctica have been thinning and doing so at an increasing rate, likely at least in part because of global warming. Scientists are worried about its implications for significant sea level rise. The ice shelves — some of which are larger than California and… Read More

Sea Ice Still Declining, Despite Antarctica’s Gains

Sea Ice Still Declining, Despite Antarctica’s Gains

When Antarctica grabbed headlines last year because of record-high sea ice levels circling the southernmost continent, it created confusion. Its increase was so at odds with the trend of dwindling sea ice, particularly in the Arctic, that it prompted those skeptical of the science of climate change to suggest it meant ocean ice is not disappearing.… Read More

Fate of Earth’s Ice Comes Further Into Focus

Fate of Earth’s Ice Comes Further Into Focus

The frigid, ice-covered expanses that make up Earth’s poles are some of the fastest warming parts of the planet as human activity drives up greenhouse gas levels in the atmosphere, altering the global climate. What happens to all that ice isn’t just a concern for these remote, frozen wilds: The ice sheets that cover Greenland and Antarctica hold… Read More

Warm Water Invasion Is Fueling Striking Antarctic Ice Melt

Warm Water Invasion Is Fueling Striking Antarctic Ice Melt

The tongues of ice that stick out from and help to buttress the frozen expanse of Antarctica are increasingly under assault from warm ocean waters invading from below, potentially impact global sea level rise a new study says. That warm water intrusion eats away at the parts of Antarctica’s glaciers that flow into and float atop coastal waters.… Read More
