Watch: How to Dance Like a Glacier

By Jeremy Deaton

Eighteenth century French choreographer Jean-Georges Noverre once wrote, "A fine picture is but the image of nature; a finished ballet is nature herself." Noverre was arguing for the immediacy of dance. Twenty-first century American choreographer Diana Movius took his words literally.

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.

Melting Glaciers Dramatically Alter Canada's Yukon

Glaciers in Canada's Yukon territory are melting at an alarming pace, causing bodies of water to dry up and whipping up dust storms in the region, CBC News reported.

Researchers have determined that the rapidly retreating Kaskawulsh Glacier in the Yukon's St. Elias Mountain region cannot compensate for the volume it is losing now each year.

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.

NASA Study of Increasingly Dire Global Water Shortages Finds 'Clear Human Fingerprints'

By Julia Conley

With a first-of-its-kind satellite study, NASA scientists have identified more than 30 parts of the globe where the depletion of freshwater has been most dramatic, largely due to human activity and the climate crisis.

Parts of India, the Middle East, Australia, the Arctic, Antarctica, and California were among the places pointed out in the new study, published in Nature on Wednesday, as areas where an overuse of groundwater resources from irrigation, agricultural, and industry projects, as well as the loss of glaciers and ice sheets, have led to water shortages.

Antarctic Seals Help Scientists Track Melting Ice Sheet

Scientists studying the warming waters and salinity of the Southern Ocean's Amundsen Sea—which surrounds the Thwaites and Pine Island glaciers, two of the largest and fastest-retreating glaciers in Antarctica—are using a novel method to collect data.

They temporarily glued sensors onto the fur of Antarctic seals. Really.

Satellite Reveals Troubling Retreat of Patagonian Glaciers

Researchers with the European Space Agency (ESA) have mapped in stunning detail the extensive retreat of South America's Patagonian ice fields, where some glaciers are melting at the highest rates on Earth and contribute to global sea level rise.

In a report this week, ESA revealed that between the years 2011 and 2017, Patagonia's ice fields receded at a rate of more than 21 gigatonnes (Gt)—21 billion metric tons—a year, the equivalent to adding 0.06 millimeters to global sea level.
