Can solar radiation modification prevent a future collapse of the West Antarctic Ice Sheet?

The stability of the West Antarctic Ice Sheet is uncertain on a rapidly warming planet. Geoengineering through solar radiation modification could halt global warming and potentially delay the demise of the ice sheet. But in high-greenhouse-gas-emission scenarios, collapse of the ice sheet ensues despite such intervention.
