Al,
We know you werent trying to stir up anything,
and I just posted because I know that everytime an iceberg breaks off its a cause celebre for the global warmers. They absolutely have a field day over it.
I have to admit, anytime something huge like this happens the forces that are unleashed and the physics are fascinating. Who wouldnt want to witness something that big start breaking off. Of course, it happens over many years, but at some point there must be the straw that finally breaks its back, and wham, it starts to really go.
