Expanding protected areas to safeguard the unique biodiversity, such as these emperor penguins, is just part of the Australian research role in Antarctica. Australian Antarctic Division

Private funding could help Australia’s role in the Antarctic

The Australian government’s blueprint for the Antarctic is due out soon. Given the recent cuts in public funding for science, what hope is there for any extra monies for the polar region. And what should…

Our pollution reached Antarctica long before the great explorers

Lead pollution from Australia reached Antarctica in 1889 – long before the frozen continent’s golden age of exploration – and has remained there ever since, new research shows. In our study, published…

Data error discovery slows trend of growing Antarctic sea ice

The amount of the earth’s ocean surface covered by sea ice has been continually observed by satellites and its extent estimated since 1978. The trend has been for shrinking sea ice in the Arctic and, more…

What climate tipping points should we be looking out for?

The concept of a “tipping point” – a threshold beyond which a system shifts to a new state – is becoming a familiar one in discussions of the climate. Examples of tipping points are everywhere: a glass…

Volcanic history of the Antarctic helps with future climate models

An international study of ice cores has helped researchers pave the way for a better understanding of how Antarctica’s volcanoes…

In Conversation: what does the future hold for Antarctica?

Antarctica is a continent less suited to human habitation than any other. Temperatures rise above freezing only briefly on the northern Antarctic peninsula. At the coast mean temperatures range between…

In Conversation on Antarctic sovereignty: full discussion

Antarctica is a continent less suited to human habitation than any other. Temperatures rise above freezing only briefly on the northern Antarctic peninsula. At the coast mean temperatures range between…

The Arctic melts, but oceans and ozone hole may cool Antarctica

Over recent decades, scientists have watched the Arctic and Antarctic polar regions respond in starkly different and perhaps surprising ways to the effects of increasing human influence on the Earth’s…

What is the paradox of increasing Antarctic sea ice really telling us?

This year could well see a new record set for the extent of Antarctic sea ice – hot on the heels of last year’s record, which in turn is part of a puzzling 33-year trend in increasing sea ice around Antarctica…
The Thwaites Glacier is among several in West Antarctica that is already retreating. NASA

We can now only watch as West Antarctica’s ice sheets collapse

Antarctic climate science is having a moment – a worrying moment. Three new studies have all concluded that the West Antarctic Ice Sheet has begun to collapse. This collapse will impact humanity for generations…

Antarctic volcanoes help preserve life in the freezer

Antarctica was once covered in lush, subtropical forests, inhabited by diverse plants and animals including large dinosaurs. That’s going back many millions of years. These days, Antarctica is 99.7% covered…

An icebreaker gets stuck in the ice, photos are used to mislead

As the saying goes, a picture is worth a thousand words, and by now you might have seen dramatic images of passengers on stranded icebreaker Akademik Shokalskiy being rescued by helicopter last Friday…
Tractors and quad bikes – seen here at Australia’s Mawson Station – are only two of many forms of transport used in Antarctica. Chris Wilson/Australian Antarctic Division

Why the ‘infrastructure PM’ can’t give Antarctica the cold shoulder

Prime Minister Tony Abbott recently declared that he wanted to be known as the “infrastructure prime minister”. But what of Australia’s iciest infrastructure – that located in Antarctica? A 20-year strategic…

US shutdown means one sad tale after another for scientists

As a researcher funded by the US National Science Foundation (NSF), since October 1, I’ve known that I will be not be receiving my monthly fellowship. This has meant that my work, investigating genes…

What lies beneath … evidence of life under the Antarctic ice

That extreme lifeforms might exist in the cold and dark lakes hidden kilometres beneath the Antarctic ice sheet has fascinated scientists for decades. Understanding how life can exist in the most extreme…

Antarctic ice melting from below

Antarctic ice shelves are losing ice by melting from their undersides, as well as by calving icebergs. A study compiled by…
Lack of funding is just the tip of the iceberg for Australian Antarctic research. AAP/Australian Antarctic Division

Australian Antarctic science is being frozen out by budget cuts

A hundred years after Australian explorer and geologist Douglas Mawson returned from his epic scientific adventures in Antarctica, Australia’s scientific exploration of the icy southern continent has all…
