Unravelling the mystery of how life in Antarctica survived past ice ages involved sampling some of the oldest museum records. When combined with a dating database, a familiar story is revealed.
Macquarie Island isn’t just a windswept rock halfway to Antarctica. It’s a globally unique home to dozens of bird and marine mammal species, hence the government’s plans to give it greater protection.
If left unchecked, the complete melting of the West Antarctic ice sheet would cause a global sea level increase of 3.3 metres in the distant future.
The melting of the Antarctic ice sheet will contribute for a long time to sea level rise, which will test humanity’s capacity to adapt.

March 2 marks the 65th anniversary of the completion of the Trans-Antarctic Expedition. Intended to demonstrate Commonwealth unity, it became a symbol of Britain’s imperial decline.
Scientists think Mars rovers may have some blind spots when it comes to finding signs of life.
Our Mars rovers might not be sensitive enough to detect signs of life. But lessons from Antarctica might make future missions more successful.
Nasa’s new ‘Blue Marble’ photograph, taken on December 8 2022.
A new image has been taken of the whole Earth 50 years after the first - revealing noticeable changes to its surface.
PFAS are persistent and spread through the atmosphere via hydrological processes.
Toxic synthetic chemicals, called PFAS, are a serious threat to humans and wildlife – but many people are unaware of them.
More of us than ever want to see the ice continent. But is the environmental awakening many return with worth the emissions and possible environmental damage?
The species at risk include flowering plants, moss and lichens, tough invertebrates and breeding seabirds.
Transantarctic Mountains peaks are some of the only parts of the continent not buried beneath ice.

Emperor penguins survive in a ‘Goldilocks zone’ between too much sea ice and too little. Climate change is having an impact.
Women in Antarctica experience significant barriers of sexism, prejudice and abuse.

The U.S. Antarctic Program struggles to keep women safe – and through the continent’s history, discrimination and prejudice are rampant.

The edge of the Thwaites Glacier extends into the Amundsen Sea in western Antarctica.
If and when the Thwaites Glacier melts, it will result in nearly 0.6 metres of sea level rise, but it holds back another three metres of sea level rise lurking within the Antarctic continent. Listen to The Conversation Weekly podcast.

The place where oceans turn into ice holds the key to understanding some of the complex interactions of Earth’s climate. Thankfully, we’re making progress.
Southern Ocean heat uptake accounts for almost all the planet’s ocean warming, thereby controlling the rate of climate change.

A recent report reveals 72% of women stationed in Antarctica have experienced sexual harassment. This is a shockingly high number – but change is possible.

Antarctica’s ice shelves have helped insulate it from dangerous levels of ice loss. But this is changing.
