Clouds over Australia’s Davis Research Station, containing ice particles that activate ozone-depleting chemicals, triggering the annual ozone hole.
The treaty to limit the destruction of the ozone layer is hailed as the most successful environmental agreement of all time. Three decades on, the ozone layer is slowly but surely returning to health.
Melting Antarctic ice can trigger effects on the other side of the globe.
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.
Mosses are sensitive to even minor changes in their living conditions.
Mosses are sensitive to even minor changes in their living conditions, and scientists traditionally tramped through difficult terrain to collect data on them.
The Mt. Takeha volcano in west Antartica rises more than 2,000 metres above the surrounding ice sheet.
18,000 years ago a volcano in Antartica began erupting – and didn't stop for 192 years.

More than 100 volcanoes lie beneath the continent's ice sheet.
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.
Analysis of 12,000-year-old Antarctic ice reveals that methane leaks from fossil fuel extraction play a larger role than previously thought.
Century-old fruit cake, anyone?

Fruit cake may last a century, but it's got nothing on honey.
The authors have collaborated on an Antarctic research project, investigating tiny ice crystals and their role in climate.

When artists and scientists get together, they fuel each other's creativity and inquiry.
Celebrity cows: Southern Girl and Iceberg enjoy a ‘hay cocktail’ at the Commodore Hotel in New York.

What would possess an Antarctic expedition to take dairy cows to the icy continent? Back in 1933, Admiral Byrd did so for reasons of image-making, publicity and territorial ambition.
Into the unknown.
In this episode of The Anthill podcast we are off exploring: land, sea and space.

Enormous Antarctic icebergs are a rare but natural occurrence.
The crack along the Larsen C ice has grown significantly over the past few weeks.
A huge iceberg is set to break free from Antarctica. While the iceberg isn't hugely concerning, it could herald the breakup of the entire Larsen C ice shelf, which could trigger more sea-level rise.
Best-case scenario, how much are we locked into?
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
Adélie penguin at the Mt Siple breeding colony, West Antarctica.
Climate change is set to expand Antarctica's ice-free area, potentially helping native species to flourish but also paving the way for invasive species to gain a foothold.
Furious winds keep the McMurdo Dry Valleys in Anarctica free of snow and ice. Calcites found in the valleys have revealed the secrets of ancient subglacial volcanoes.
Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
Trips to Antartica are part of the ‘last chance’ tourism to environmentally fragile places.
No place is off-limits to tourism, so the industry grows without restriction – but there are ways to curb the environmental damage it does.

The new sub allows scientists to access some of the most remote and hazardous environments in the ocean.
Senator Jacqui Lambie, speaking on Q&A.
During a Q&A discussion about climate change, Tasmanian Senator Jacqui Lambie said it was four degrees hotter 110,000 years ago. Is that right?
A photo from Sea Shepherd allegedly shows a Japanese whaling vessel with a dead minke whale on board.

Japan is once again allegedly killing whales in Antarctica. But after taking Japan to international court in 2014, there's not much Australia can do.
