Westerners need to get a grip and man-up with reality. To think "we," gnats that we are, could identify, let alone manipulate, climate trends, is idiocy. We need to get on with our civilizations and lives. We don't manipulate the climate, it manipulates us.
But if we did that then the neo-luddites wouldn't have a handy excuse to destroy Western civilization.
