Because there is no global warming, of course! :
Actually whether there is or not is well debated...apparently there have been warming/melting trends years before people existed. I'm sort of in the camp that the pollution isnt good anyhow, so why not work at reducing the effects...just in case
But that would go against the energy/oil businesses and hit them pretty hard, so since we'd rather die choking and up to our necks in water than cut the oil profits, there we go.
But thats nothing...wait until the island of La Palma in the Canary's lets go.
If nobody's heard of this, this island is split in half up the middle and on top of an active volcano. During one of its next eruptions (last one in 1949), the shelf on the west side will let go. Its more a question of when than if. When that happens, the tsunami created will wipe out the entire eastern seaboard of the united states to a depth of about 20 miles inland, destroying new york, boston, DC and most of florida along with any other coastal towns. Further, many european countries would take severe damage as well and a fairly substantial wave would hit northern africa. The east coast would get maybe a few hours notice before they were hit...nowhere near long enough to evacuate. Europe and africa would be hit much faster, but not as hard
Unless we find a way to stop volcanic eruptions or hold up 500 billlion tons of rock, or some way to calm a 5000 mile long, 50 yard high wall of water before it drops. Could be tomorrow. Or a thousand years from now.
Learning this was a real turning point for me. Millions dead, world economy tossed on its ear. Because a rock fell in the water.
