I don't know what your point is Clem. The drying out of Lake Mead is not a result of Global Warming.

Do I think that Global Warming may be a result of man ...? I'm sure that some of it is ... but it has nothing to do with consumption of Lake Mead's water resources.

BTW: What ever happened to the hole in the ozone layer that alledgedly threatened life on this planet? Has it closed up? We don't hear much about it anymore.
