As the world prevaricates over climate action, Antarctica’s future is shrouded in uncertainty. Hamish Pritchard/British Antarctic Survey

Antarctica has lost 3 trillion tonnes of ice in 25 years. Time is running out for the frozen continent

What will Antarctica look like in 2070? Will the icy wilderness we know today survive, or will it succumb to climate change and human pressure? Our choices over the coming decade will seal its fate.

Short-term changes in Antarctica’s ice shelves are key to predicting their long-term fate

Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
The Homeward Bound initiative works with women in science to enhance their opportunity to take up leadership roles globally. Oli Samson

How a trip to Antarctica became a real-life experiment in decision-making

This year 77 women took part in the largest all-female expedition to Antarctica as part of a leadership training program. Rough weather enroute put group decision-making skills to the test.

How Antarctic ice melt can be a tipping point for the whole planet’s climate

The climate secrets contained in an ancient tree that lived through abrupt global change reveal how Antarctica can trigger rapid warming in the north by dumping cold water into the Southern Ocean.
The analysis of large amounts of ice from Antarctica’s Taylor Valley has helped scientists to tease apart the natural and human-made sources of the potent greenhouse gas methane. Hinrich Schaefer

Antarctic ice reveals that fossil fuel extraction leaks more methane than thought

Analysis of 12,000-year-old Antarctic ice reveals that methane leaks from fossil fuel extraction play a larger role than previously thought.
