Phys.org / Amplifying feedbacks could drive Greenland ice sheet to near-complete disappearance

Greenland, which has been prominently in the news in recent days, hosts a vast ice sheet. If it melts, it will become one of the largest contributors to global sea-level rise. Under a high-emissions scenario, the Greenland ...
