Now the Pentagon tells Bush:

Climate change will destroy us

Climate change 'should be elevated beyond a scientific debate to a US national security concern', say the authors, Peter Schwartz, CIA consultant and former head of planning at Royal Dutch/Shell Group, and Doug Randall of the California-based Global Business Network.

An imminent scenario of catastrophic climate change is 'plausible and would challenge United States national security in ways that should be considered immediately', they conclude. As early as next year widespread flooding by a rise in sea levels will create major upheaval for millions.

Not that it will make any difference to Bush - but he will have a hard time squaring the circle of being a protect the US president and then not acting on what the Pentagon says is the biggest threat. Its about friggin' time they did.
