Donuel, This has not happened in thousands of years anywhere on Earth is not true. I was in Abidjan a weekend we got a quarter of our annual rainfall, back in the 1970's. This stuff happens. It's rare, not unprecedented.

Why do we build cities in floodplains, why do we build them so big they cannot possibly be evacuated, and why O why do people choose to live in them?

How much money is the insurance industry making on this kind of thing?
