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.

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.

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.

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.

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.

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.

Scientists say that increasing number of houseflies that arrive in Antarctica on ships are surviving as the continent warms up. Their growing population can introduce deadly pathogens that could have a harmful effect on indigenous lifeforms.

Large-scale melting of snow and ice on Antarctica's massive Ross Ice Shelf, brought on by an unusually warm stretch of weather in the austral summer of 2015-2016, has been documented for the very first time, according to a new study.

While the idea of towing a massive iceberg from Antarctica to supply drinking water to millions of people in the United Arab Emirates may sound ludicrous, it is in the planning stages. But, does this "stopgap measure" actually address the real problem?
