Seafloor landforms reveal that ice sheets can collapse at 600 metres per day.
Unravelling the mystery of how life in Antarctica survived past ice ages involved sampling some of the oldest museum records. When combined with a dating database, a familiar story is revealed.
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.
Scientists used satellites to map tens of thousands of glacial landforms in Antarctica’s highest mountains.
Interestingly, we also found a major period of ice loss in Antarctica was followed by a period of gain, starting some 5,000 years ago.
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.
Liquid water below the ice determines how fast an ice stream flows. As the ice sheet gets thinner, more of that salty groundwater could rise.
Scientists have crafted the world’s first “treasure map” to reveal Antarctica’s meteorites. These chunks of stone-like material could throw light on the mysteries of our early solar system.
For the first time since satellites started studying the continent, East Antarctica has lost an entire ice shelf.
Researchers have surveyed an Antarctic under-ice river for the first time directly, and their observations support the idea that such sub-glacial rivers form estuaries as they flow into the ocean.
Climate change is making ocean levels rise in two ways. It’s a problem that will endure even after the world stabilizes and slashes greenhouse gas pollution.
If the world is to adapt to sea level rise with minimal cost, we must address the uncertainty surrounding Antarctica’s melting ice sheet. This requires significant investment in scientific capacity.
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.
A future of heat and strife or humanity’s finest hour – our response to climate change today will define the 21st century.
Microphones on the seafloor recorded life under the Antarctic ice for two years – inadvertently catching seal trills and chirps that are above the range of human hearing. Could they be for navigation?
Our research shows the Antarctic could be closer to a tipping point than previously thought.
Living sustainably has its challenges, but none greater than in the climate and geography of Antarctica.
New research shows that warming by more than 2°C could be a tipping point for Antarctica’s ice sheets, resulting in widespread meltdown and changes to the world’s shorelines for centuries to come.
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.
