How do scientists know this? I don't believe they can actually measure with rulers or determine their mass with some sort of "glacial" scale. Maybe most of the Ice is under the surface and we just don't know it. Last week Japan was colder than normal. Satelite imaging can be distorted along a round surface. I think this is more climategate. Please people give it up. This is more made up Al Gore and Greenpeace fluff stuff.

freedumb86, instead of assuming that scientists have no accurate way to measure ice melt, you should follow the links, read their research reports, and find out for yourself what methods they are using. Then you can judge how valid you think their methods are. Otherwise you are as (or more) guilty of making things up as you claim scientists, Al Gore, and Greenpeace are making up.

While I have read that the Artic icecap is melting, I've also ready other reports from other scientists that say that the Antartic ice cap is actually expanding? Why is that mentioned in this report?

The west Antarctic ice is increasing due to increased snowfall in that region due to changed weather patterns. The overall mass of ice in the south pole region is still decreasing slightly. Greenland's melt is much more worrisome since all of that ice is land based and has the potential to raise sea level by quite a bit in only a few dozen years. And it's beginning to melt much faster than anyone predicted.

Ice floating on the seas - ice sheets and ice bergs do not contribute to see rises. Certainly some because of expansion of warming water. But ice on land - on Greenland and Antartic will cause the sea level to rise when it melts. Because there is so much water as ice on land if it were all to melt and/or slide into the sea, sea levels may rise over 200 feet. If that happens everyone will be heading to Minnesota. We are going to need some better roads.

Rather than worry about a rising sea level, which is dangerous enough considering how many people on this planet live in coastal areas, I would worry about the impact the melting and warming of the atmosphere has on the jet stream. The jet stream moves the weather and can cause droughts (perhaps like the one we're in) catastrophic rain storms, and perhaps strengthen hurricanes. The jet stream is the wild card in the global warming story.

There is the possibility that a large release of fresh water from Greenland into the North Atlantic might shut down the North Atlantic Gyre. This circular current plays a major role in circulating heat and ocean water in the northern hemisphere. No one really knows what the ramifications would be for the human race if the Gyre shuts down.
