Antarctic sea ice cover fell to an all-time low recently and hasn't yet recovered. Why? The initial answers could lie in an unlikely place – the tropics.
There are some limits on what countries can do in the Antarctic, but not when it comes to science.
Under the terms of the current treaty all commercial mining is forbidden, but rumblings of discontent are stirring beneath the ice.
A flavor of diplomacy that focuses on science cuts through political differences and finds new ways for nations to work together.
Mosses are sensitive to even minor changes in their living conditions, and scientists traditionally tramped through difficult terrain to collect data on them.
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.
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?
Antarctica hangs in the balance. Five cities have the chance of securing the future of this fragile continent.
It's one of the remotest places on Earth and yet is still claimed by six nations – including Australia.
A warming Earth could see invading species arrive in Antarctica via the floating "taxi service" of the sea. That could be a threat to the southern continent's delicate ecosystem.
What gaps have the CSIRO cuts left in climate research?
As the world warms, Antarctica's melting ice will likely reach the point of no return.
Iron and nutrients from Antarctica's bedrock are carried into the oceans – nourishing entire food webs.
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.
If we burned all fossil fuels, the loss of ice in Antarctica would raise sea levels 160 to 200 feet, but even our current trajectory could lead to dramatic sea level rise.
Deception is the premier tourist destination in the Antarctic. It's also the volcano that scientists are still not sure why it's there.
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.
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…
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…
