Ocean warming threatens the viability of 60% of Antarctic ice shelves
Nature - The viability of Antarctic ice shelves under low rates and high rates of global warming is modelled to estimate when it will become unfeasible for the ice shelves to maintain their...

This study therefore confirms that today's choices regarding greenhouse gas emission reduction will directly determine the future of Antarctica and of global sea-level rise.

The main driver for the increased mass loss that leads to non-viability is the warming of the ocean. The warm water circulates beneath the ice shelves, leading to increased melt at their base.

These 38 ice shelves act as a break on the outflow of large glacial drainage basins that have the potential to add 10 m to global sea level on the long term if all their ice flows into the ocean.

In a high-emission scenario reaching up to 12°C global warming by 2300, 38 out of 64 Antarctic ice shelves could be destined to disappear in the long term. 26 of these already by 2150. In a low-emission scenario limiting global warming to 2°C, 63 out of 64 ice shelves would remain viable.
