Burning all of the world’s available fossil-fuel resources would result in the complete melting of the Antarctic ice sheet, a new study to be published in Science Advances shows. The Antarctic ice masses store water equivalent to more than 50 meters of sea-level rise. The new calculations show that Antarctica’s long-term contribution to sea-level rise could likely be restricted to a few meters that could still be manageable, if global warming did not exceed 2 degrees. Crossing this threshold, however, would in the long run destabilize both West and East Antarctica – causing sea-level rise that would reshape coastal regions around the globe for millennia to come.
