The rocky road to accurate sea-level predictions
– dirt and water under Greenland control future sea-level rise
The type of material present under glaciers has a big impact on how fast they slide towards the ocean. Scientists face a challenging task to acquire data of this under-ice landscape, let alone how to represent it accurately in models of future sea-level rise. “Choosing the wrong equations for the under-ice landscape can have the same effect on the predicted contribution to sea-level rise as a warming of several degrees,” says Henning Åkesson, who led a new published study on Petermann Glacier in Greenland.
