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. _________________ The end is nigh! OR forums die APRIL 1. Don't lose contact!

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 _________________ where-ever you get it - there you have it. - Anon. |

They say water is rising because the polar ice caps are melting (They actually got thicker this year according to The American Legion magazine) but here is my problem. Put an ice cube in a glass, then fill it to the rim with water. When the ice melts, why doesn't the glass overflow?
Seems the same would hold true about the ice caps and ocean levels? | TRY GETTING YOUR INFORMATION FROM ONE OTHER THAN .....THE AMERICAN LEGION MAGAZINE FOR DRUNKS.BB |

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:

Brant, this is the same artice posted in th eoriginal. At least the facts are the same. As iI said before water is raising at a rate on 0.2 feet/yr. that must have been one flat a$$ed island to disappear so quickly.
I don't believe anyone is disputing global warming. Its been warming to some degree since the last ice age ended. The issue is some idiots are blaming humans. The earth has undergone many temperature changes all by itself over the last billions of years. There is nothing we have done to earth to to make the temperature rise or lower then or now. There is nothing we can do to stop it either. At some point it will reverse and we will move into the next ice age.
I realize people will be displaced but many live way too close to shorelines now. we see this from repeated damage from storms and people rebuild in the same place. In this area we see repeated floods in the same areas and people are stupid enough to demand the government stop future floods. They live in floodplains, they will always get flooded, its nature and we can't control these things. we can't control global warming either. |
