According to the United States Geological Service (www.usgs.gov), if the glaciers on Greenland melt completely, the oceans will rise about 6.5 meters (over 21 feet). If the ice cap on Antartica melts completely, the oceans will rise an additional 64.8 meters (over 212 feet). If all the glaciers in the world melt, the total rise in the oceans worldwide will be 80.32 meters (over 263 feet - that is one quarter of the height of the Chrysler Building).
If the oceans rise by only 10m (about 33 feet), at least one quarter of the population of the USA will have to find somewhere else to to live.

The real danger is the ice currently on land melting and the water being deposited into the sea, Greenland and Antarctica. The water frozen over water in the northern arctic region is not a problem with rising sea levels. If you have a glass of ice water filled to the top when the ice melts the water does not pour over the sides because the amount of water displaced by the ice is equal in proportion to the ice itself. I did also hear that ocean levels would rise about 26 feet or roughly 8 or 9 meters or so.

Al Gore says that his research indicates that if the small section of Antarctica (that he discusses in his documentary) melted, the seas would rise 20 ft. Another 20 ft. would be added if Greenland melted. I have to assume that he is talking about the ice above sea level, or any land, since the ice below would only displace itself. I would have to do the math, I guess, but that seems way over the top to me.

I just got the TIME "naturals extreme magazine and in there it says if the ice caps melted completely the ocean level would raise more than 200 ft around the world!

long before they could melt the salinity of the oceans would be vastly altered,decreasing the density of the water and upsetting the currents.thereby causing another ice age.

between 5 and 10 meters

around 61 metres. so be plenty of land left, just the top of mountains or extremely high land mass

The influx of fresh water will shut down ocean currents.This they say will throw us into another ice age.

Not worth thinking about that disaster.
