Sea ice extent sinks to record lows at both poles

Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent. This is the lowest maximum in the 38-year satellite record. On the opposite side of the planet, on March 3 sea ice around Antarctica hit its lowest extent ever recorded by...

NSIDC reports record low Arctic sea ice extent

Average Arctic sea ice extent for November set a record low, reflecting unusually high air temperatures, winds from the south, and a warm ocean, NSIDC reports. Since October, Arctic ice extent has been more than two standard deviations lower than the long-term...

West Antarctic Ice Sheet breaking apart from the inside out

A new study has found the glacier bounding the West Antarctic Ice Sheet is breaking apart from the inside out. The Pine Island Glacier, one of the glaciers which will probably rapidly retreat, forms an important part of the ice shelf of the West Antarctic Ice Sheet....

Rare phenomena: giant ice balls form on a beach in Siberia

Thousands of large ice balls have appeared on a beach in Nyda, Russian Siberia in late October 2016 and remain to this day. Many US meteorologists believe this is a sign of extra snowy winter throughout the United States. This is the first time that this rare...

Mysterious waves in the Antarctic atmosphere triggered by ice shelf vibrations

According to the new research, the ripples and undulations in the atmosphere above Antarctica are most likely induced by the low-frequency vibrations of the Ross Ice Shelf, the largest ice shelf in the world, extending over half a million square kilometers (188 000...

2016 Arctic sea ice minimum the second-lowest on record

The Arctic sea ice appears to have reached its seasonal minimum for 2016 on September 10, the NSIDC said yesterday in a preliminary announcement. A relatively rapid loss of sea ice in the first ten days of September has pushed the ice extent to a statistical tie...
