Antarctic Melting Increased 6x in the Past 40 Years

The results of what researchers say is the longest-running study of Antarctica's ice mass have been published, and they are dramatic. Yearly ice loss has increased by a factor of six in the past 40 years, contributing more than half an inch to global sea level rise, a University of California, Irvine (UCI) press release reported. The researchers also observed consistent ice loss from East Antarctica, which boasts the world's largest ice sheet and has traditionally been assumed to be more stable.

"The places undergoing changes in Antarctica are not limited to just a couple places," lead author and UCI chair of earth system science Eric Rignot told The Washington Post. "They seem to be more extensive than what we thought. That, to me, seems to be reason for concern."

Ice Sheets in Greenland, Antarctica Could Reach Catastrophic 'Tipping Points' if We Don't Limit Warming

Scientists just gave us another terrifying reason to limit global warming to 1.5 degrees Celsius above pre-industrial levels: If temperatures push much beyond that point, both Greenland and Antarctica's ice sheets could reach a point where nothing can stop them from melting.

An international team of researchers published this chilling finding in Nature Climate Change Monday. The researchers set out to study how the ice sheets would fare in a warming world, and the results were urgent.

Iceberg 5x the Size of Manhattan Breaks Off Pine Island Glacier

The Pine Island Glacier, the fastest-retreating glacier in Antarctica, lost another massive chunk of ice earlier this week.

A 115-square-mile section calved off the ice shelf on Oct. 29. That's roughly the five times the size of Manhattan.

NASA Flew Over Not One But Two Rectangular Icebergs

Last week, NASA tweeted a photo of a perfectly natural and rectangular iceberg spotted during a flyover of the northern Antarctic Peninsula.

The unusual image blew up online and now NASA is back with more photos of weirdly angular icebergs from the same Operation IceBridge trip.

'Headless Chicken Monster' to Help Antarctic Conservation Efforts

Enypniasties eximia—a deep-sea swimming sea cucumber scientists have affectionately called the "headless chicken monster"has been caught on camera for the first time in Antarctic waters thanks to new underwater camera technology developed by Australian researchers.

Footage of the finned sea creature will be used to aid important marine conservation efforts in the Southern Ocean.

Scientists Study Ice Shelf by Listening to Its Changing Sounds

By Marlene Cimons

Researchers monitoring vibrations from Antarctica's Ross Ice Shelf were flabbergasted not long ago to hear something unexpected—the ice was "singing" to them. "We were stunned by a rich variety of time-varying tones that make up this newly described sort of signal," said Rick Aster, professor of geosciences at Colorado State University, one of the scientists involved in the study.

Thom Yorke of Radiohead Releases Song With Greenpeace to Help Antarctica

Greenpeace is on a mission to create the largest protected area on earth in Antarctica, and it just gained a very talented ally to help promote that goal.

Radiohead frontman Thom Yorke released a single Tuesday in support of the campaign called "Hands Off Antarctica," The Guardian reported.

Scientists Link Southern Ocean's Rapid Warming to Human Activity

In the past few decades, the Southern Ocean surrounding Antarctica has gotten less salty and has warmed at roughly twice the rate of global oceans overall.

Now, in a new study, scientists found convincing evidence that these trends are the result of two human influences: climate change from greenhouse gas emissions and the depletion of the ozone layer.

NASA's New Space Laser to Measure Earth's Changing Ice

NASA will soon activate the "most advanced laser instrument of its kind" to study Earth's changing polar ice.

The incredibly precise Advanced Topographic Laser Altimeter System (ATLAS) is the main feature of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) that successfully launched into space from the Vandenberg Air Force Base in California on Sept. 15.
