They returned with images and data showing that red-hot magma has been rising from deep inside the earth and blown the tops off dozens of submarine volcanoes, four kilometres below the ice."Jets or fountains of material were probably blasted one, maybe even two, kilometres up into the water," says geophysicist Robert Sohn of the Woods Hole Oceanographic Institution, who led the expedition.

The result of the Arctic, Antarctic and ice in Greenland disappearing is a major one and involves three main areas.
1: Sea levels will rise.
2: Temperatures will rise. The ice sheets in the Arctic act as a reflector. Sunshine and a lot of the heat is reflected back in to space by the ice. If there is no ice, that heat is absorbed by the water, thus warming the water, which just means more rapid melting of what ever ice that remains. Also, warmer sea temperatures means a change in weather patterns.
3: Ocean currents will change. The fresh water from the melted ice sheets will mix with the salt water oceans and will throw off the ocean currents that determine our weather patterns. It will change how cold it is in one area of the world, how hot it is in another, how wet it is in this place, and how dry it is in that place. This will occur at times in the year that you wouldn't typically see those weather patterns. Winter may not be cold in areas it usually is. Summer may not be as wet as it usually is in other areas. The weather patterns will change.
This isn't speculation.

I completely agree.

If all of this ice melted, would there be massive floods. From the pictures I seen in school, these ice shelves are massive. They are talking about all of the ice melting by the summer, it's kind of like it is going to happen overnight.
Actually not. Since all of the ice at the North Pole is sea ice. melting it will not cause any change in sea levels -- sort of like the ice cubes melting in your drink -- it doesn't make the drink overflow.
The melting ice that can cause changes in the ocean levels is the antarctic and Greenland ice sheets sheets that are on land. As they melt, they add to the amount of water in the oceans. Remember that there is no land ice in the arctic

If indeed the ice is sea-ice that would mean NO rising of the waters, this is basic physics.
If the ice is predominantly land ice then yes, we would see some rising of the waters.

As it happens this topic was picked up by another ATS-er, Hellmutt, back in March 08. These are the images he used:
That thread was based on the following quote:
The polar cap in the Arctic may well disappear this summer due to the global warming, Dr. Olav Orheim, head of the Norwegian International Polar Year Secretariat, said on Friday.
Here is the thread from which the quote was taken:
