The faster melting rates are also changing the balance of freshwater and saltwater in the oceans, affecting both ocean circulation and global weather in unknown ways, according to findings published Friday in Science Advances.
The study focused on two Antarctic glaciers — which collectively hold enough water to raise global sea levels by 5 feet.
Scientists have long known that Antarctica’s Denman glacier — like many across the once-vast icelands of the polar regions — was melting from beneath.
