I don't understand where that number comes from, or does it mean anything?
~~Anthropogenic Global Warming ™ ping~~
It's the angle of the dangle X the mass of the ass squared by the torque of the pork ...
Surface of the world’s oceans in volume assuming a 20 foot deep layer and adjusted for the loss of volume when ice melts into water.
That's part of the very definition of a Liberal. A Liberal is one who shows great disdain for laws or plainly ignores them. Whether in physics or economics or any number of other subjects, immutable laws are just too "mean" for a good, feeling Liberal.
"If I don't like it, it must not be true!"
Yes. They will. Within 10 Billion years the sun will expand to be a red giant and melt the ice caps... And the rocks. That is a given.

I did the math on this once and came to the rough conclussion that about 35 feet of ice would have to melt off of all land covering ice caps to raise the oceans 1 foot.
AGW/CC back of the envelope calculation that seems to be correct, but I can’t figure where he got the number noted in my comment# 1.

His assumption that the enegy radiating from the sun is constant is incorrect and the variations have been known and quantified for decades.
D-
I have a problem with this part:
"There is a difference of 300* between these two figures. Even if I am wrong by an order of magnitude, there is still an enormous difference. This does NOT mean that ice caps have not melted in the distant past nor that ice-age glaciers have not grown to cover much of the northern hemisphere; it simply means that the time scales involved to move sufficient quantities of heat to effect such melting or freezing occur over what we scientists commonly call "geological" time scales, i.e. hundreds of thousands and millions of years."
We know pretty much for a fact that very large glaciers covered all of Canada and probably 20-25% of the northern tier of United States only about 15-18,000 years ago. Now, virtually all of that is gone.
It obviously didn't take "geologic" time scales to melt those glaciers - i.e. "hundreds of thousands of years". A couple of thousand years got the job done.
I've booked that weekend away....

Volcanic activity can contribute as well.
That's understood. He's just assuming the worst with a five degree warming. It doesn't compute with the latent heat required for the phase change from ice to water.
Eventually the oceans will boil and no amount of icebergs will help.
theres not enough ice to raise the sea level very much,theres not enough heat to melt the ice and it doesnt matter,science has never been a barrier to hysteria, and hysteria on a global scale is a dangerous thing,especially when its as evil as this socialist garbage.The only truth is that the sun and volcanoes are sources of heat,sun goes through cycles,hotter and cooler,volcanoes are under the artic,antartic,oceans and they put out more greenhouse gases than we ever will in the history of mankind!It seems to me to be a balancing system that we cannot affect and may never understand,,,but geeshhh! if we can promote carbon free societies that great satan,,the USA will go down.! You think everybody in America will sit and watch us be destroyed,I dont,I think conservatism will have its best days ahead ,trying to save the last bastion of sanity on earth.
Assume that the earth is a sphere (which it is not), Mean Sea Level (MSL) occurs at radius R, add 20 feet. Calculate the volume of the two spheres and subtract the MSL volume from the plus 20 feet volume.
This, according to the author, gives you a volume of approximately (because the Earth is not a sphere) 6x10^24 m^3 or 600,000,000,000,000,000,000,000 cubic meters of H2O.
Thats a lot of water.
By those standards there's hardly any ice left to be melted anyway.
NOTE: the Ice Lobe covering the Lower Midwest penetrated into a still Temperate climatological zone. The ice there melted rapidly even during the height of the glaciation in North America. Ice continued to flow South to that area and was always melting. You could hunt Mastadons at the foot of a two mile high glacier, and while dining, be eaten leisurly by a local sabre toothed tiger!
