The melting of the Antarctic ice sheet will contribute for a long time to sea level rise, which will test humanity’s capacity to adapt.

The trend globally is for countries to be explicit about their maritime interests, underpinned by a sound security strategy.
Southern Ocean heat uptake accounts for almost all the planet’s ocean warming, thereby controlling the rate of climate change.
Migaloo, where are you? How searching for the iconic white humpback whale connects us all with the ocean.
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.
The resting place of Shackleton’s ill-fated ship is now an international heritage site, and a reminder of how Antarctica’s place in our collective consciousness has changed since the ‘heroic age’.
This enormous, unprecedented algal bloom could have profound implications for carbon dioxide levels in the atmosphere and for the marine ecosystem.
These giant predators are helping solve the mystery of Earth’s cooling shift some 50 million years ago.
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.
Glaciers aren’t sterile wastelands – they’re chock-full of microscopic life.
Australia is considering removing humpback whales from the threatened species list after their numbers rebounded in recent decades. But the mammals face new threats.
Whales are rediscovering their old haunts in the Arctic and Southern oceans after centuries of hunting.
Oceans 21 is a Conversation international series examining the history and future of the world’s ocean.
The Southern (Antarctic) Ocean is our planet’s primary storage of heat and carbon, and it’s home to extraordinary life forms, from tiny algae and spineless creatures to penguins, seals and whales.
‘Antarctic cities’ residents care deeply about the continent, with environmental concerns outweighing economic priorities. Asked about its future, they feel a mix of hope, pessimism and sadness.
For 200 years, a small number of countries have exploited the marine wildlife of Antarctica, often with devastating impact on their populations.
Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.
Our new research has more than doubled the known fossil record of seals in Australia.
As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That’s always puzzled scientists, but now they think they know what happened.
