Researchers from the Australian Antarctic Division have completed one of the most ambitious expeditions since the 1960s, but the world's ice remains locked deep in the frozen continent.

Researchers uncover new information about the coldest times in the continent's history by studying a system of caves on South Australia's Limestone Coast.

On February 13, 1954, a group of expeditioners set up camp in Antarctica. Seventy years on, their huskies are no longer there but Australia's presence at Mawson Station remains vital for scientific research on the frozen continent.

Australians are still reeling from a summer of extreme weather events, so the news a US climate agency is on La Niña watch could spark fears about the years ahead. However, Australian scientists are taking a cautious approach.

More than 85 per cent of Australians live within 50 kilometres of the ocean, but the variation in weather across any slice of this narrow coastal band is substantial.

China opens its fifth Antarctic research station, starting operations in an outpost due south of Australia and New Zealand for the first time.

Kate Selway has spent the past two months battling subzero temperatures, perpetual sunlight, and getting stuck on the ice to help unlock the secrets of Antarctica’s melting glaciers.

In a whitewashed corner of one of the world's coldest continents, Australian scientists are living in tents and undertaking some of the most ambitious research in 20 years.

A study has found that the Greenland ice sheet lost one-fifth more mass than previously estimated, which could have implications for ocean currents that regulate temperatures in Europe and North America.

The researcher found that Greenland's ice level was relatively steady from 1985 up until 2000 and began to rapidly melt thereafter.

This week, inhabitants of the Southern Hemisphere will experience their longest stretch of daylight hours over a 24-hour period, as the summer solstice approaches once again.

Popular theories about industry emissions damaging ancient rock art in Western Australia's Pilbara region are yet to be conclusively proven, according to a new report.

The research shows that the glaciers have been cooling and drying in recent decades.

As the clean-up begins, local scientists took the rare chance to observe the powerful weather system close-up.

New research shows global carbon emissions from fossil fuels have increased over the past year despite most of the world committing to net zero targets.

Recent satellite images reveal that the iceberg, weighing nearly a trillion metric tonnes, is drifting quickly past the northern tip of the Antarctic Peninsula, aided by strong winds and currents.

Last week, the planet appeared to briefly breach a climate threshold set by world governments for the first time. Experts say it is just another sign of how much the planet is warming.

A study of a thousand glaciers in the area shows the rate of melting entering a new phase over the last two decades.

Between November 2022 and October this year, the average global temperature was more than 1.3 degrees Celsius above pre-industrial levels, and more record highs are on the way.

Officials at the Australian Antarctic Division were left scrambling after a decision to block RSV Nuyina from transiting the Tasman Bridge and refuelling close to port, with the true cost of a 660km detour now revealed.

Sand movement has been recorded on this beach on the New South Wales southern coast since 1971. It's one of the longest data sets in the world, and holds important clues for the future.

The asteroid 66 million years ago erased three-quarters of the world's species in an instant — but new research suggests the final blow may have unfolded in the following years, as the skies were darkened by clouds of debris and temperatures plunged.

Using satellite data, researchers uncover an ancient river system hidden for millions of years beneath the East Antarctic Ice Sheet.

The Marshall Islands are surrounded by seawater, but fresh water is in short supply. As the Pacific nation stares down the barrel of climate change, people are working to help mitigate what's to come.
