Antarctica is shedding ice at an accelerating rate

The melting of Antarctica is accelerating at an alarming rate, with about 3 trillion tons of ice disappearing since 1992, an international team of ice experts said in a new study.

Sea level fears as more of giant Antarctic glacier floating than thought

Sydney - More of a giant France-sized glacier in Antarctica is floating on the ocean than previously thought, scientists said Tuesday, raising fears it could melt faster as the climate warms and have a dramatic impact on rising sea-levels.

Antarctic sea ice shrinks for second-straight year

Sydney - Sea ice cover in Antarctica has dropped to its second-lowest on record, Australian authorities said Friday, adding that it was not yet clear what was driving the reduction after several years of record-highs.

Antarctica: a laboratory for climate change

A decade ago, a thick layer of ice covered the Collins Glacier on Antarctica's King George Island.Now, the rocky landscape is visible to the naked eye, in a region that is both a victim of and a laboratory for climate change.

Scientists set off to explore new Antarctic ecosystem

London - A team of international scientists led by the British Antarctic Survey set off on Wednesday to explore a mysterious marine ecosystem that has lain hidden under an ice shelf for up to 120,000 years.

Robots en route to Antarctica to study underside of ice shelves

It has become increasingly common to see cliff-sized chunks of glacial ice falling into the Southern Ocean, suggestive of a warming climate. But scientists don't know what's going on beneath Antarctica's ice sheets., so they are preparing to find out.

Evidence points to collapse of Pine Island and Thwaites glaciers

In a remote region of Antarctica known as Pine Island Bay, the Thwaites and Pine Island glaciers sprawl across a plain over 150-miles-long, widening as they go inland to a reserve of ice two-miles-thick, about the size of Texas. They are melting fast.

260-million-year-old fossil forest discovered in Antarctica

Long ago, Antarctica was covered in forests. The ancient trees were able to withstand prolonged periods of pure sunlight or complete darkness, transitioning rapidly between the seasons. But they were victims of the world's greatest mass extinction event.

New ice crack forces Halley VI Research Station to close again
