Mount Erebus is Antarctica’s obvious volcano, but there is more below the ice. Josh Landis/USAP

Volcanic rift valley under Antarctica hotter than expected

The Thwaites glacier is one of the most rapidly changing in Antarctica. It’s been the focus of considerable attention in recent weeks, after scientists suggested that this sector of the huge West Antarctic…

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…

Melting glaciers deform the Earth’s mantle and crust

The significant retreat of elements of the West Antarctic ice sheet such as the Thwaites glacier recently reported in the journal Science suggests a possible sea level rise of 3 to 3.7m. This is a huge…
Antarctic tourism numbers are modest, but some nations seem to be eyeing up the continent’s industrial potential. Supplied

Is there about to be a dash for Antarctica’s resources?

Few places have captured the human imagination like Antarctica. It is colder than anywhere on Earth, bounded by rough seas, buffeted by intense winds, home to fauna that are found nowhere else and, as…

How wind helps Antarctic sea ice grow, even as the Arctic melts

Strong winds linked to climate change and the hole in the ozone layer are driving a steady increase in Antarctic sea ice, even as Arctic levels continue to shrink dramatically, a new report shows. While…

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…

New behaviour leaves Antarctic penguins on the shelf

Emperor penguins have been spotted breeding on ice shelves for the first time, where previously they were thought only to breed on the much lower ice that floats on the ocean surface. It is not clear whether…

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…

Building a telescope in the coldest place on Earth

Russia’s Vostok station in Antarctica must be one of the scariest places on Earth. Temperatures regularly drop below -80C, and there is no way in or out for nine months of the year. The inhabitants become…
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…

Was penguin evolution driven by a cooling Antarctic?

Penguins are a remarkable group of flightless birds. We tend to think of them as Antarctic birds, but they actually inhabit an extremely diverse range of habitats from subzero Antarctic coastline to the…
