"One of the biggest challenges in predicting Antarctica’s deeply uncertain
future is understanding exactly what’s driving its ice loss.
A vast network of lakes and streams lies beneath the thick ice sheet. This
water can lubricate the ice, allowing it to slide more rapidly toward the
ocean.
Our new research shows “subglacial water” plays a far larger role in Antarctic
ice loss than previously thought. If it’s not properly accounted for, future
sea-level rise may be vastly underestimated.
Including the effects of evolving subglacial water in ice sheet models can
triple the amount of ice flowing to the ocean. This adds more than two metres
to global sea levels by 2300, with potentially enormous consequences for
coastal communities worldwide."
