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.

The IPCC 2007 Fourth Assessment of climate change science concluded that large reductions in the emissions of greenhouse gases, principally CO2, are needed soon to slow the increase of atmospheric concentrations, and avoid reaching unacceptable levels.However, climate change is happening even faster than previously estimated; global CO2 emissions since 2000 have been higher than even the highest predictions, Arctic sea ice has been melting at rates much faster than predicted, and the rise in the sea level has become more rapid.

One hears of dire predictions of sea - level rises which don't seem to be eventuating, of stasis in global temperatures that weren't predicted, of claimed ad - hoc appeals to aerosol effects, etc., and that's without going into the general atmosphere of hostility to people like me who genuinely think the case for harmful AGW effects looks shaky.
