The "ice melting in a glass" argument does seem compelling at first, until you consider the land-based ice masses on Greenland and Antarctica... That ice is not displacing ocean water, it's sitting on top of solid ground. This would be as if you had a glass of water and a bucket of snow... when the bucket of snow melts, you pour that into the glass and viola! Overflow.

Another molecule family that does not conform to expansion and contraction rules is latex (all your rubbers and a lot of plastics...)-- most substances expand when heated... but since rubber molecules are a long chain (which gives them their elasticity), when they are heated, the chain breaks down and the molecule "collapses"--- thus making the substance contract. Water expands when it gets hot or cold... rubber contracts when it gets hot or cold.

You're right, E, I forgot about natural rubber, and its entropy release. ..
But if the question remains about global warming related to rising sea levels, I don't think there's any reliable evidence because there are far too many factors involved : solar activity, sea currents, volcanism, the tilt of the earth, the reflective discrepancy of ice and land, biological activity changing the atmosphere....and on and on... Factoring this list of variables makes chaos theory look like candy, and the Drake Equation look like real science.

Truth is, nobody knows, and the variables can be manipulated to support any conclusion, from warming to cooling to permanent stasis. My favorite opinion of our global future involves the Earth switching poles, doing a cha-cha with the moon, and forever dancing with the stars

You should subscribe-but that would mean you would have had to serve your country and we know you didn't have the stones for that. But that mag does have a lot of photos in it so your inablity to read would not hinder you.

Here's more evidence of the effects of global warming. I post this fully realizing that some of you don't give a damn about facts:
