A massive Antarctic ice shelf is showing signs of cracking and could trigger worldwide flooding.

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.

How do organisms survive extreme conditions – and how can their adaptations help us develop better technology?

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.

Antarctic Ice Sheet melting to lift sea level higher than thought, study says. New calculations show the rise due to warming would be 30% above forecasts.

In a new study, we found that a third of Antarctica's ice shelves could collapse at 4°C of global warming.

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?

Whales are rediscovering their old haunts in the Arctic and Southern oceans after centuries of hunting.
