The only problem with all the predictions about the level of the World Ocean rising is that, the World Ocean is refusing to rise up in support of the predictions, the other problem is that ice is frozen fresh water and frozen fresh water only covers about 5 % of this planet above sea level and frozen water under the level of the World Ocean does not count as the World Ocean will fall a small amount if that ice melts, so if the ice there is enough to get the World Ocean to rise and significant amount then it must be piled up very high, I cubic kilometer of water as ice, should it melt, would make 1000 square kilometers rise by one meter, so when you use this simple math then somewhere on the planet, above the level of the sea, then there must be over 500,000 cubic kilometers of ice, piled up and just waiting to melt, strange that no one can find that amount of ice, all these morons who talk about the rise of the World Ocean in tens of meters, this includes you Peter Garrett or Mr. 7 Meters, the ice does not exist to allow this amount of rise in the World Ocean, it is just not there.
