The Larsen C Iceberg Is Already Cracking Up

The Larsen C Iceberg Is Already Cracking Up

The trillion-ton iceberg that broke off Antarctica last week will not go quietly into the night. New satellite imagery reveals that the iceberg, dubbed A68, is already shifting shape along with the remaining Larsen C ice shelf itself. The iceberg has traveled about 1.5 miles from the ice shelf it was formerly attached to. A piece of ice the size … Read More

Arctic Heat Is Becoming More Common and Persistent

Arctic Heat Is Becoming More Common and Persistent

The Arctic is a bastion of cold, blustery weather. But in the latest sign of how quickly changes are happening, new research published this week shows that the Arctic has seen more frequent bouts of warm air and longer stretches of mild weather. The new findings show that while warm snaps have occurred even as far as back as the 1890s, a massive… Read More

These Images Show Just How Big the Larsen C Iceberg Is

These Images Show Just How Big the Larsen C Iceberg Is

The Larsen C ice shelf has calved an iceberg after months of waiting and watching. With an area the size of Delaware and a volume of 277 cubic miles, its measurements boggle the mind. Even written comparisons don’t fully convey the hulking hunk of ice currently adrift in the Weddell Sea. After all, can you really imagine 463 million Olympic-sized … Read More

The Larsen C Iceberg Finally Broke Away. Now There’s a Trillion-Ton Iceberg Adrift

The Larsen C Iceberg Finally Broke Away. Now There’s a Trillion-Ton Iceberg Adrift

The inevitable moment of reckoning for the Larsen C ice shelf arrived. The growing rift that carved across one of the Antarctica Peninsula’s largest ice shelves reached its end, sending a 2,240-square mile iceberg spiraling into the sea. Welcome to the world, iceberg A68. The massive slab of ice, equivalent to the size of Delaware and large enough … Read More

The Larsen C Iceberg Is Expected to Have Company

The Larsen C Iceberg Is Expected to Have Company

It’s stressful being an iceberg hanging on by a thread. If you want proof, look no further than the Larsen C ice shelf. Just three miles stand between the crack that’s been cutting across the ice shelf since 2010 and open water. When it breaks through, it will cleave a trillion-ton iceberg. The stress of having a huge iceberg-to-be nearing its … Read More

The Arctic Has Been Crazy Warm All Year. This Is What It Means for Sea Ice

The Arctic Has Been Crazy Warm All Year. This Is What It Means for Sea Ice

Melt season has begun in earnest in the Arctic. Scientists will spend the next few months watching sea ice turn into open water until the ice pack hits its nadir in early fall. The vagaries of the weather and ocean currents will play a major role in determining where this year’s Arctic sea ice minimum ranks. But the steady drumbeat of climate… Read More

Scientists Know How Big the Larsen C Iceberg Will Be

Scientists Know How Big the Larsen C Iceberg Will Be

It’s the final countdown. The European Space Agency said on Wednesday that just three miles separate the Larsen C crack — a rift slicing the front off a major Antarctic ice shelf — from open water. Like a tailor with a tape measure, scientists have been measuring the crack using ESA satellites. The next Sentinel-1 satellite pass will happen later … Read More

Antarctica’s Ice-Free Areas to Increase By 2100

Antarctica’s Ice-Free Areas to Increase By 2100

Climate change will cause ice-free areas on Antarctica to increase by up to a quarter by 2100, threatening the diversity of the unique terrestrial plant and animal life that exists there, according to projections from the first study examining the question in detail. If emissions of greenhouse gasses are not reduced, projected warming and changes … Read More
