We did not look at one or two glaciers. We looked at all of them.

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

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

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

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

A few years back, we thought ice sheets might grow because of increased precipitation. Now we see that rates of glacier flow are changing. We think the process that is winning overall is the rate of glacier flow.
