I am too busy, and too sick, to blog much recently. But I did want to mention the September issue of National Geographic, which has a very good article on sea level rise. (Miami is toast; even seawalls won't help, because the land sits on porous rock. Water already shoots out of their manholes at very high tides.)
One interesting number was that the total amount of water in all living organisms (on Earth) is 269 cubic miles. Cubic miles.
If I calculated correctly, that works out to 2.2 millimeters if spread across the entire surface of the planet. Just enough to keep the surface wet -- about like Oregon 8 months of the year
