We're about in the same boat. It could have happened, and it's probably too late for both of us, but maybe we each helped a little. Eventually it will be done.
I was pondering a Noah's Ark situation... what items to send into orbit that we'd use to re-biosculpt the damaged area (really the whole planet: 65m yrs ago the shrews re-engineered the biosphere)...theoretically it might take six months for water/wind/atmospheric systems to re-integrate into something vaguely familiar.
Looks like we really are going to lose California, but on the bright side, look what that Cretaceous monster did to develop tourism in the Yucatan.
