Upside-down rivers lapping at the bottoms of ice sheets and brilliant blue mini-lakes dotted on top may be speeding up Antarctic melting. As the Earth continues to warm, both processes could hasten the demise of Antarctica’s icy armor.
A new research suggests a 2ºC (3.6ºF) rise in global temperatures could melt more than a million square kilometers (386,000 square miles) of ice if the temperatures are sustained long enough.
