Best-case scenario, how much are we locked into?
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?

Climate change is set to expand Antarctica's ice-free area, potentially helping native species to flourish but also paving the way for invasive species to gain a foothold.
Furious winds keep the McMurdo Dry Valleys in Anarctica free of snow and ice. Calcites found in the valleys have revealed the secrets of ancient subglacial volcanoes.
Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
Trips to Antartica are part of the ‘last chance’ tourism to environmentally fragile places.
No place is off-limits to tourism, so the industry grows without restriction – but there are ways to curb the environmental damage it does.

The new sub allows scientists to access some of the most remote and hazardous environments in the ocean.
Senator Jacqui Lambie, speaking on Q&A.
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?
A photo from Sea Shepherd allegedly shows a Japanese whaling vessel with a dead minke whale on board.

Japan is once again allegedly killing whales in Antarctica. But after taking Japan to international court in 2014, there's not much Australia can do.

There is no doubt that 2016 has been a record-breaking year for the Earth’s climate.
Next year the Ross Sea will be home to the world’s largest marine reserve.

After years of stalled negotiations, China has ended its opposition to the world's largest marine park off Antarctica - part of a wider trend towards increased Chinese involvement in global governance.
The Balleny Islands off East Antarctica - one of the many stops along the way.
Why spend three months completing a lap of Antarctica (and probably getting seasick along the way)? It's the only way to get vital clues about the remote Southern Ocean and its influence on the planet.
Antarctica hangs in the balance. Five cities have the chance of securing the future of this fragile continent.
An icebreaker makes its way through Antarctica’s sea ice.
After record-breaking amounts of sea ice in Antartica, this year we're seeing record lows.
End of an era? The Macquarie Island research base could close next year.
The shock decision to close Australia's year-round research station at Macquarie Island will make monitoring Antarctica and the Southern Ocean harder, and will force Tasmania to get creative.
What can life on Antarctica tell us about future colonies on Mars or other planets?

Dallas Rogers speaks with Prof Juan Francisco Salazar about studying the research community in Antarctica to learn about what colonising Mars and other planets might look like.
Britain’s industrial pioneers couldn’t have known how they would affect the climate.
The first signs that humans were warming the climate appeared much earlier in the northern hemisphere - way back in the 1830s. But now the trend is emerging all over the globe.
Antarctica’s ice sheets will continue to melt long after this century.

If we accept that 2 degrees warming is dangerous this century, we have to accept it is dangerous beyond.
What lies beneath: bedrock peeks through the Antarctic ice.

Buried beneath kilometres-thick slabs of ice are rivers and huge lakes - some of which are teeming with microbes that thrive in a world without light or oxygen.
The Chinese icebreaker Xue Long sails from Fremantle Harbour on its way home from Antarctica.
Australia and China both have a keen interest in the frozen continent. And while they don't agree on everything, there is great scope for scientific collaboration.

It's one of the remotest places on Earth and yet is still claimed by six nations – including Australia.
Ban on CFCs in aerosol sprays and refrigerants has led to a steady shrinking of the ozone hole.
What the Montreal Protocol has done for the ozone hole threat other international accords could do for climate change – if we all agree.
