Good initial point in that it is the coastal cities that are in danger, New York, Seattle, Portland, San Francisco, all the libtard places that need to be flushed out. If global warming would guarantee the above, then I vote for rapid and decisive global warming.
Think what a service the rising ocean levels will do. Seattle, Portland, San Francisco, L.A. Oakland and San Diego sidewalks will be flushed clean of all that homeless poop and pee. The Earth is renewing itself.
