I agree, AGW appears to be horse hockey.
But . . .

Floating ice cubes affect water levels one way.
ice volume < water volume, no real rise.

Mountains of ice on land that melt into a body of water affect water levels differently. More akin to run-off during a flood.

proving the point of the article about posters and knowledge of science; Often just innocent mistakes versus scientists who know better, who persist in AGW tripe.

Floating ice cubes affect water levels one way. ice volume < water volume, no real rise.

The density of ice is less than water, especially of salt water. A floating ice cube/berg will displace a volume of seawater equal to the weight of the ice cube/berg. When the frozen fresh water of the iceberg melts, because it is less dense than the heavier saltwater of the sea, that freshwater will occupy more volume than what the iceberg displaced.

Still, if you took all the floating ice bobbing around on the great briny seas of the world, the total sea level increase would be... 4 centimeters.

4 centimeters!?!
