Pentagon tells Bush: climate change will destroy us - not quite

Secret report warns of rioting and nuclear war
Britain will be 'Siberian' in less than 20 years
Threat to the world is greater than terrorism

This is clearly overstated. This sounds like it was a Futures Studies scenario to guide Pentagon planning if global warming alarmists, who are increasingly backed by most scientists, are true.

Yes, here is a copy of that supposedly secret report's Executive Summary.

Submerging Markets - As the Pentagon report itself acknowledges, it is not a "forecast," but a "what if?" exercise in "thinking about the unthinkable,"in the great tradition of Dr. Edward Teller and DOD's "wintry doom" scenarios of the late 1950s and the 1980s. The aim was to construct a "plausible," if not necessarily probable, scenario, in order (in the authors' words) to "dramatize" the possible consequences of "an abrupt slowing" of the ocean's "thermohaline circulation" (TC), the deep ocean currents that have a profound influence on subsidiary ones like the Gulf Stream and the Humboldt Current.

...So what do we conclude from all this? Stepping back from the Pentagon report's apocalyptics, it does concur, in broad strokes, with the growing sense of urgency among many professional scientists about global warming, and our own sense that the case for taking action is now stronger than ever.
