Subject: Re: A "simple" physics problem?
_______________________________________________BTW, this question is tied into some environmental issues. Any risein the ocean levels due to global warming will be due to ice that's
currently on land (ice sheets in Greenland or Antarctica). Melting
sea ice (i.e. the north polar ice cap)will not contribute to the rise
in sea level because floating sea ice is already displacing ocean
water.
Warming of the existing sea water will also cause sea levels to
rise, due to "thermal expansion."
