"It's so far outside anything we've seen, it's almost mind-blowing," says Walter Meier, who monitors sea-ice with the National Snow and Ice Data Center.
An unstable Antarctica could have far-reaching consequences, polar experts warn.
Antarctica's huge ice expanse regulates the planet's temperature, as the white surface reflects the Sun's energy back into the atmosphere and also cools the water beneath and near it.
Without its ice cooling the planet, Antarctica could transform from Earth's refrigerator to a radiator, experts say.
