A funding bid to establish a polar security research program has been knocked back, despite the changing geopolitical dynamics in Antarctica and the Southern Ocean.

Proposed "geoengineering" projects designed to reduce the impacts of global warming in polar regions would be ineffective, extremely costly and environmentally dangerous, researchers have warned.

More than 100,000 international tourists — including almost 10,000 Australians — travel to Antarctica each year. But a new study shows that getting there creates a significant carbon footprint.

Glaciers on the remote Australian territory of Heard Island have lost almost a quarter of their size over the past seven decades amid rising temperatures in the sub-Antarctic region, new research show...

Australia's ability to conduct strategic, in-depth, and long-term research in Antarctica is being compromised by "terminating" funding models for key programs, scientists warn.

A new forecast suggests annual tourist numbers in Antarctica could almost quadruple within a decade, prompting calls for mitigation measures to reduce potential impacts on the continent's sensitive en...

From giant sea spiders to "sea pigs" and "sea butterflies" — analysing the rich biodiversity in Antarctica has thrilled researchers studying the impacts of climate change.

Scientists have found it difficult to capture longer-term changes to Antarctic sea ice as satellite records date from 45 years ago, but a recent reconstruction winds the record back to 1899.

An abandoned Australian base in Antarctica has undergone an initial clean-up after a French inspection team last year raised concerns hazardous waste at the site posed an environmental risk.
