dave, Glaciers exposed to the #ocean are melting much faster than previously predicted. 🧊 ☀️
Melt #water underneath the #glacier in the 'grounding zone cavity' significantly increases the projections of glacier mass loss as these zones reduce the amount of resistance glaciers experience as they flow out into the sea.
The result is that past models underestimate the severity of #sealevel rise over the coming decades
