Re: RE: Only nuclear power can now halt global warming

Hi all:

The following link to "Volume of Earth's Polar Ice Caps" answers a lot of the questions and WAGs that 

have been part of this thread about ocean rise and volume of water tied up in the polar ice caps as it 

relates to global warming/nuclear power:



http://hypertextbook.com/facts/2000/HannaBerenblit.shtml



Of note from the above: "An ice cap is defined as a thick permanent covering of ice and snow on 

land.....Ice caps were formed millions of years ago from layers of snow that were compressed 

together...."



Greenland - Standardized volume of ice result: 2.8 E6 km^3 [670,000 cubic miles of ice!]

            Maximum sea rise potential: 6.5 meters



Antarctica: - Standardized volume of ice result: 30.1 E6 km^3 [about 7 million cubic miles of ice!]

              Maximum sea rise potential: 73.3 meters



So if the polar caps melted in their entirety over time, maximum sea rise about 80 meters [261 feet].
