Hi, again, Storm Sorry to take so long, but I needed a couple of hours for experimentation (Just kidding-really!)
I certainly hope you didn't take offense. I was not implying that YOU got your science from movies. However, many people do.
About my "bad science"... (Please, I'm not being testy or sarcastic...just trying to explain) Tried your Achimedes experiment...I did, indeed, put FRESH WATER ice in a container full of SALT WATER. Allowed it to melt. Surprise Surprise...water overflowed the container and I had to clean up water from my counter. The problem is the different densities of the two substances.
As for the the coast of Antarctica...the same principle works there, too, especially since glaciers (100 per cent on land) calve ice into salt water. The pack ice would behave as above.
The statements about your snowfall: Yup, you had a big one...sounds about as local as my statements about the ski resorts.
The person I took my data about global snowfall from is a climatologist with NOAA. If he's wrong, then I'm mis-informed. (It was at a science conference for NSTA.)
Of course, we're only touching the "tip of the iceberg" here. For example, any warming trend that could cause even a partial melting of glacial ice would have much more far reaching effects. If it's enough to melt polar ice, then there would still be an increase in sea levels due to expansion of the trillions of tons of water near the ocean's surface. Hey, we see it happen in the Pacific in every El Nino year, so there is every reason to believe it would happen on a larger scale.
An interesting side note is that global warming could actually increase snowfall in some areas, particularly coastal regions. Smaller ice caps would increase the surface area open to evaporation. That increased atmospheric load of moisture could make it to places that would otherwise have remained dry. If it's a mountainous coastal region, snowfall could definitely be increased.
Still lots to consider. But I'd make a lousy movie writer. My scripts would be way too full of boring details...such as good science.
