Combustion of available fossil fuel resources sufficient to eliminate the Antarctic Ice Sheet
The Antarctic Ice Sheet stores water equivalent to 58 m in global sea-level rise. We show in simulations using the Parallel Ice Sheet Model that burning the currently attainable fossil fuel resources is sufficient to eliminate the ice sheet. With cumulative fossil fuel emissions of 10,000 gigatonnes...

The Antarctic Ice Sheet stores water equivalent to 58 m in global sea-level rise.
