This is due to climate warming. |
This is raising concern on the effects of the polar caps. |
We are witnessing enormous changes, and it will take some time before we understand how it happened, although it is clearly a result of warming around the glaciers. |
We did not look at one or two glaciers. We looked at all of them. |
We don't think these are just bursts. We haven't seen any of these glaciers coming back to normal. |
What it means right now is that Greenland is producing 20 percent of the sea rise. We think that contribution will increase from generation to generation. |
What surprised us was the magnitude of the changes. |
What we found is this is probably the dominant response of the ice sheets. |
Whether the warming is effected by man is not something that we can directly determine with this study. |
