Reply #2: The point that gets neglected, unfortunately,

[EST]

when discussing the consequences of global warming is the fact that the melting of those huge icecaps and the rising sea levels change the stress on the earth's crust.
As has been pointed out with the rising of the appalachian range and the earthquakes in the area of the Aswan dam, among others, this rapid change should be expected to touch off an extraordinary number of tectonic disturbances, resulting, most likely, in an enormous increase in the quantity and intensity of volcanoes and earthquakes, world wide. This increase is not likely to subside for fifty thousand years or more. Damn dumb humans.
