Just a thought. Why is it that every time that every time a scientist warns about global warming the first post is by a warming denial professional? Just a thought.

If you dont believe me ask nasa http://www.giss.nasa.gov/research/briefs/gornitz_09/ To think that melting the remaining ice sheets wont affect future sea level rise is preposterous.

Any geologist can tell you that sea levels rose about 125 meters in the ten thousand years from 15ooo to 5000 years ago, with very little sea level rise since[average about 14cm per centuary].. Sea levels around Tuvalu have actually fallen in the last 20 years, in spite of what the environmentalists keep insisting. Please do a reality check.

It's a system! That means many elements, some more important at various times of the year. Wind currents are impacted by the ice or lack thereof AND the ice is impacted by the wind passing over it. The saline in arctic ice is minimal, so the sea water flows at a different depth when it is saturated by salt free ice water. The Gulf Stream then changes it's depth, impacting weather in Europe, causing more snow. The snow reflects the sun, cooling the air, etc etc. see? A system with many currents. Overall it means the ice melts and our weather changes. And 2/3 of Florida vanishes beneath the waves. Kurt, you can’t derive from this report that CO2 has nothing to do with the lack of ice.

Here's a mechanism by which summer warmth can destroy thick multiyear pack ice, without direct melting. When summer warmth melts enough thin ice, favorable winds can create areas of open water, and the swells that can break up thick multiyear ice. Something similar has been suggested for Antarctica's ice shelves. They may be vulnerable to long swells from distant South Pacific storms. Wow!

It tells me something very interesting: The lack of multi-year ice has got nothing to do with CO2. It is an effect of deep water currents. Thanks for the report.
