The Greenland ice sheet's contribution to sea level is an issue of considerable societal and scientific importance.

Greenland is probably going to contribute more and faster to sea level rise than predicted.

It's likely that Greenland is going to contribute more and faster to rising sea levels than previously estimated.

I think this will heighten concerns that maybe the sea-level models are a little too conservative.

The behavior of the glaciers that dump ice into the sea is the most important aspect of understanding how an ice sheet will evolve in a changing climate. It takes a long time to build and melt an ice sheet, but glaciers can react quickly to temperature changes.

If this ice melts in Greenland it can shut down the Gulf Current.
