Where a "real" national security crisis looms.... obviously the August 6th PDB didn't signal a "real" one. Aparrently, greenhouse gas and global warming (check the recent weather) are not signalling one either.

>>CLIMATE COLLAPSE
The Pentagon's Weather Nightmare
The climate could change radically, and fast. That would be the mother of all national security issues.
By David Stipp<<
>>The threat that has riveted their attention is this: Global warming, rather than causing gradual, centuries-spanning change, may be pushing the climate to a tipping point. Growing evidence suggests the ocean-atmosphere system that controls the world's climate can lurch from one state to another in less than a decade—like a
canoe that's gradually tilted until suddenly it flips over. Scientists don't know how close the system is to a critical threshold. But abrupt climate change may well occur in the not-too-distant future. If it does, the need to rapidly adapt may overwhelm many societies—thereby upsetting the geopolitical balance of power.<<
