Global Warming

[VRM]

Ok, Scott - I went back and figured out what the problem is.

You are correct regarding a freshwater ice cube in a glass of fresh water with equal densities for both.

I am correct regarding a floating ice cube (or iceberg) with any degree of fresh water in the ocean raising the sea level more than it displaces.

My mistake was in applying what I know of ice bouyancy/density of icebergs to a freshwater ice cube in a fresh water glass (not many of us drink glasses of saltwater). Roughly 11% remains above water whereas an ice cube of equal density to the water in a glass has a little less than 9% above water.

Sorry about that...Does it make more sense now?

I suppose that is what I get for doing my own homework rather than just copying and pasting someone elses...

I tried in my own words to prove it, I then had to resort to someone else's.

I think I mentioned in an earlier post about averaging the ice. The experiment would be the same if you used both sea water and sea ice. The problem would be to determine how much freshwater ice/snow is on top of the sea ice.

I am wondering if the average salinity of the oceans is decreasing, that would mean that the fresh water ice on land is melting at an increased rate wouldn't it?
