Fate of ‘sleeping giant’ East Antarctic ice sheet ‘in our hands’ – study ice

The fate of the world’s largest ice sheet is in human hands, a new analysis suggests. The vast East Antarctic ice sheet should remain stable if global warming is limited to 2 degrees Celsius, but melting could raise sea levels by meters if the climate crisis causes temperatures to rise. The East Antarctic Ice Sheet …
