The Southern Ocean’s krill-rich waters attract multiple species of filter-feeding whales – and, increasingly, fishing boats.
Freshening seawater around Antarctica is disrupting a global ocean conveyor which regulates the climate.
Thwaites Glacier’s ice shelf appears to be splintering, and scientists fear it could give way in the next few years. A polar scientist takes us on a tour under the ice to explain the forces at work.
For the first time since satellites started studying the continent, East Antarctica has lost an entire ice shelf.

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.
