A 20-year plan welcomed for Australia in the Antarctic

The Antarctic is a vast and inhospitable place with a time scale all of its own. For the scientists who travel there to carry out research, a project can sometimes take years to plan and even longer to…

New Zealand is drying out, and here’s why

Over 2012 and 2013, parts of New Zealand experienced their worst drought in nearly 70 years. Drought is the costliest climate extreme in New Zealand; the 2012-2013 event depressed the country’s GDP by…
It may already be too late to stop Antarctic ice sliding into the ocean. EPA

Why ice sheets will keep melting for centuries to come

Ice sheets respond slowly to changes in climate, because they are so massive that they themselves dominate the climate conditions over and around them. But once they start flowing faster towards the shore…

New Antarctic sea ice record — but scientists aren’t ‘confounded’

Antarctic winter sea ice has once again broken the record for maximum extent. On September 12, the coverage measured 19.619 million square kilometres, the highest since satellite records began. The ice…

Japan could resume whaling – this time with The Hague’s blessing

Japan is reportedly set to release plans to resume killing whales in the Southern Ocean in the 2015-16 season. It seems like a defiant move, coming just six months after the International Court of Justice…
Expanding protected areas to safeguard the unique biodiversity, such as these emperor penguins, is just part of the Australian research role in Antarctica. Australian Antarctic Division

Private funding could help Australia’s role in the Antarctic

The Australian government’s blueprint for the Antarctic is due out soon. Given the recent cuts in public funding for science, what hope is there for any extra monies for the polar region. And what should…

Our pollution reached Antarctica long before the great explorers

Lead pollution from Australia reached Antarctica in 1889 – long before the frozen continent’s golden age of exploration – and has remained there ever since, new research shows. In our study, published…

Data error discovery slows trend of growing Antarctic sea ice

The amount of the earth’s ocean surface covered by sea ice has been continually observed by satellites and its extent estimated since 1978. The trend has been for shrinking sea ice in the Arctic and, more…

What climate tipping points should we be looking out for?

The concept of a “tipping point” – a threshold beyond which a system shifts to a new state – is becoming a familiar one in discussions of the climate. Examples of tipping points are everywhere: a glass…

Volcanic history of the Antarctic helps with future climate models

An international study of ice cores has helped researchers pave the way for a better understanding of how Antarctica’s volcanoes have affected the global climate over the past 2,000 years. The research…

In Conversation: what does the future hold for Antarctica?

Antarctica is a continent less suited to human habitation than any other. Temperatures rise above freezing only briefly on the northern Antarctic peninsula. At the coast mean temperatures range between…

In Conversation on Antarctic sovereignty: full discussion

Antarctica is a continent less suited to human habitation than any other. Temperatures rise above freezing only briefly on the northern Antarctic peninsula. At the coast mean temperatures range between…

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…
