The Observer of London has obtained a secret Pentagon report that predicts the climate change over the next 20 years could result in global catastrophe that leads to millions of deaths from war and natural disasters.

The Pentagon study predicts that major European cities will sink beneath rising seas and that Britain will suffer “Siberian”-like climate by 2020. As early as next year rising sea levels could create major upheaval for millions.

The rapid climate change will challenge U.S. power and lead to nuclear conflict, mega-droughts, famine and widespread rioting across the world.

The report concludes: “Disruption and conflict will be endemic features of life. Once again, warfare would define human life.” The White House has consistently denied climate change is even occurring. A representative from Greenpeace said, “You’ve got a President who says global warming is a hoax, and across the Potomac River you’ve got a Pentagon preparing for climate wars. It’s pretty scary when Bush starts to ignore his own government on this issue.”

Influential 82-year-old Pentagon defense adviser Andrew Marshall, who is close to Donald Rumsfeld, commissioned the climate change report. Marshall has been dubbed 'Yoda' by Pentagon insiders who respect his vast experience.
