Shrinking of Antarctic ice shelves is accelerating

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.

Ozone hole closing for the year, but full recovery is decades away

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…

Japan’s new whaling program is a small win for whales, but…

This week, Japan announced a research plan for its New Scientific Whale Research Program in the Antarctic Ocean, to replace previous programs. In March this year, Japan’s previous whaling program, JARPA…

The ozone hole leaves a lasting impression on southern climate

Many people think of sunburn and skin cancer when they hear about the ozone hole. But more ultraviolet (UV) radiation isn’t the only problem. The ozone hole has also led to dramatic changes in Southern…

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…

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…

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…

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…

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…
