*RIght, no sea ports in the Pleistocene era. Of course I knew that and my question to Clark was entirely rhetorical. Why didn't he know the obvious? And there are other, possibly dire effects of the **Greenland ice sheet melting, such as change in the thermohaline current, that is shift of the Gulf Stream making Britain and Northern Europe effectively an arctic zone. Ho-hum, nothing to worry about as Florida goes below sea level. AG* -- You received this message because you are subscribed to the Google Groups "Everything List" group.
