If emissions continue at their current pace, Antarctica will cross a threshold into runaway sea rise when today’s kids are raising families. Pulling CO2 out of the air later won't stop the ice loss.

Two centuries after it was first sighted by Russian explorers, Antarctica is a key site for studying the future of Earth's climate – and for global scientific cooperation.
These lakes could threaten the future stability of parts of the Antarctic ice sheet.
Studies show that the Arctic is heating up twice as fast as the rest of the planet.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical 'cores' of the sediment and rock that's as much as two miles down at the ocean floor.
Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
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.
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.
After record-breaking amounts of sea ice in Antartica, this year we're seeing record lows.
New projections suggest the world could warm 3-7 degrees over coming centuries.
A glaciologist develops a lightweight method for probing the depths of Greenland's ice sheet to answer a crucial question: How fast is it melting?
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.
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.
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.
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.
As the world warms, Antarctica's melting ice will likely reach the point of no return.
Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
The way ice sheets respond to global warming may be more predictable than previously thought
