Under the terms of the current treaty all commercial mining is forbidden, but rumblings of discontent are stirring beneath the ice.
As the world prevaricates over climate action, Antarctica’s future is shrouded in uncertainty.

What will Antarctica look like in 2070? Will the icy wilderness we know today survive, or will it succumb to climate change and human pressure? Our choices over the coming decade will seal its fate.
Without floating sea ice, climate-weakened ice shelves are wide open to attack by waves.

Since 1995, several ice shelves off the Antarctic Peninsula have abruptly disintegrated. A new analysis suggests that these events are triggered when ice shelves lose their buffer of floating ice.

John Carpenter's The Thing is a sci-fi classic with a strong fanbase among polar scientists. So why does it resonate so much?
Melting Antarctic ice can trigger effects on the other side of the globe.
The climate secrets contained in an ancient tree that lived through abrupt global change reveal how Antarctica can trigger rapid warming in the north by dumping cold water into the Southern Ocean.

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.
Water mass enters the ocean from glaciers such as this along the Greenland coast.
Greenland's ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.

There is no doubt that 2016 has been a record-breaking year for the Earth’s climate.
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.
Knowing where the ice comes from can help work out what it will do to sea levels.
Polar ice isn't all the same - it can be divided roughly into "land ice" and "sea ice". What matters most for sea levels is how much ice slides off the land and melts in the sea.
Some parts of Antarctica’s Totten Glacier are more stable than others.
New mapping shows how Antarctica's huge Totten Glacier has retreated far inland, raising sea levels by more than a metre. Rising temperatures could trigger it to do so again.
Glaciers have been a major contributor to sea-level rise.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
We still don’t know enough about questions such as where the tipping points are for Arctic ice melt.

The Paris agreement has given us some solid targets to aim for in terms of limiting global warming. But that in turn begs a whole range of new scientific questions.
Antarctica is vital to the planet’s climate system.

Why should we care if the polar ice sheets melt hundreds of years in the future? Because they are vital for maintaining our current climate.
In some regions of the Arctic, polar bears will spend their entire lives on sea ice or the ocean.
Could polar bears slip into a hibernation-like state to tough out lean hunting during summers with little sea ice? Sadly, experiment suggests no.
Rising sea levels are one of the clearest and most widespread manifestations of climate change.
Since 1993, satellites have been used as well as tidal gauges to monitor sea level. A new calibration of this satellite record now shows that the rise in sea level is gathering pace.
The Totten Glacier, the largest in East Antarctica, has deep channels running beneath it that may allow relatively warm water into its belly.

Researchers in East Antarctica have surveyed an area the size of New South Wales to study the behaviour of the region's biggest glacier - and the secrets below the ice that could speed up its melting.
