This is a map of Antarctica that I lifted from the U.S. Geological Survey website. Antarctica has the largest mass of ice in the world by far. The white areas are land mass above sea level, the greenish areas are floating ice and blue is ocean.
If someone to ask "How much water do you think is stored in the ice in Antarctica?", I reckon it'd be fair to say there is a small ocean worth there. So what would happen if you added an ocean worth of water to our oceans?
Ice reflects 90% of the suns rays and absorbs 10%. Water on the other hand reflects only 10% and absorbs 90%. So when pools of water started forming on the Larsen Ice Shelf on the Antarctic Peninsula, the bit on the top-left of the map that points to South America, the water started to heat up and melt holes in the ice, drilling tunnels into it and making it like Swiss cheese, eventually causing it to collapse under its own weight into the ocean. These ice shelves are what is holding back the ice on the land and when they melt, huge chunks of ice slide off the land and into the ocean. The video on my post "Cool Science" may give you some idea of the consequences of that.

This is not an isolated incident. The great glaciers of the world are melting and quite a number have completely gone. The ice in Greenland is cracking and threatening to slide into the North Atlantic. The ice at the North Pole is melting. Some scientist say that it could be gone in only ten years. Have a look around on the net. The scientist all agree that we could be looking at a world that is very hard for people to live on possibly in as little as ten years and if we keep going the way we are now, vast areas of Earth will certainly be unlivable in fifty years.
