Adélie Penguins struggle to reach their nesting sites if there’s too much ice in the way.
Despite their image as cold-loving creatures, Adélie penguins could be winners from climate change.
Ice cold physics: hunting for neutrinos in Antarctica.

A cubic kilometer of clear, stable ice could help physicists answer big questions about cosmic rays and neutrinos. Hardy scientists collect data via a unique telescope at the frozen bottom of the world.
Antarctica is vital to the planet’s climate system.

Why should we care if the polar ice sheets melt hundreds of years in the future? Because they are vital for maintaining our current climate.
The continent's ice caps are melting, and both native and alien species will soon colonise the newly uncovered areas.
Antarctica is managed by the Antarctic Treaty System, which regulates what states and private companies can do.

If we're going to mine asteroids, then we need an international treaty to prevent it becoming a wild west. Thankfully we can look to Antarctica to see how such a treaty might work.
Study raises new questions over the rate of ice melting, and thus sea level rise.
NASA's former climate chief, James Hansen, is lead author on a paper that predicts rapidly rising seas this century, but not all climate scientists believe the study's models are convincing.
Gathering data at the calving front of the Ilulissat Glacier, Greenland.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
Icy waters off the western Antarctic Peninsula.
Hundreds of meters below the surface of the freezing ocean surrounding Antarctica, the seafloor is teeming with life. The animals living there have no idea that an army is on the brink of invading their tranquil environment.
Australia has a long history of first class science.

Australian scientists are listened to by government and business, but must do more to ensure their advice and work contributes to a stronger future for Australia.
The frontline of climate change.
Yet more doom and gloom from the bottom of the Earth.
Breaking the ice: while scientists increasingly understand why Antarctic sea ice is growing, it remains tricky to forecast.
Australian Antarctic Division
Antarctica's sea ice is changing in ways that scientists didn't predict, and is now causing headaches for Antarctic stations.
Rising sea levels are one of the clearest and most widespread manifestations of climate change.
Since 1993, satellites have been used as well as tidal gauges to monitor sea level. A new calibration of this satellite record now shows that the rise in sea level is gathering pace.

On the eve of a summit in Chile to discuss the protection of marine life in Antarctic waters, much still needs to be done to guard against overfishing, climate change and other threats.
The Totten Glacier, the largest in East Antarctica, has deep channels running beneath it that may allow relatively warm water into its belly.
Tas van Ommen
Researchers in East Antarctica have surveyed an area the size of New South Wales to study the behaviour of the region's biggest glacier - and the secrets below the ice that could speed up its melting.
Antarctica’s Brunt Ice Shelf photographed in October 2011 from NASA’s DC-8 research aircraft during an Operation IceBridge flight.
Researchers find that ice around Antarctica shrank quickly last decade, raising concerns over this buttress against melting land-based ice and future sea-level rise.
These ‘cliffs’ can be the height of a skyscraper.

A massive glacier tongue sticking out off the edge of the continent has been snapping off every 70 years.
Not too hot, not too cold, but just right.

Emperor penguins are adapted to the bitter cold of Antarctica, but a new study reveals that during the last ice age it got too cold even for them.
Policing toothfish is not as straightforward as Sea Shepherd would like it to be.

This morning, Sea Shepherd Conservation Society vessels leave port to pursue a new campaign in the Southern Ocean — but this time, it’s not all about whales. Operation Icefish will target vessels fishing…
We can’t figure it out.
For several years now climatologists have puzzled over an apparent conundrum: why is Antarctic sea ice continuing to expand, albeit at the relatively slow rate of about one to two percent per decade, while…
These clouds – formed high in the Antarctic atmosphere during spring – provide a place where ozone-destroying chemicals can form.
Imagine an environmental crisis caused by a colourless, odourless gas, in minute concentrations, building up in the atmosphere. There is no expert consensus, but in the face of considerable uncertainty…
