After the Bush administration was heavily criticized by a number of top scientists over its 'suppression of scientific information', now a Pentagon report is taking up the question of global warming, climate change and is warning of possible consequences.
A secret report, suppressed by US defense chiefs and obtained by The Observer, warns that major European cities will be sunk beneath rising seas as Britain is plunged into a 'Siberian' climate by 2020. Nuclear conflict, mega-droughts, famine and widespread rioting will erupt across the world.
The document predicts that abrupt climate change could bring the planet to the edge of anarchy as countries develop a nuclear threat to defend and secure dwindling food, water and energy supplies. The threat to global stability vastly eclipses that of terrorism, say the few experts privy to its contents.
Scientists say that global warming could bring about a flip towards a colder climate for much of northern Europe. The Gulf Stream, a warm water ocean current which brings climatic moderation to the Atlantic shores of Europe, may be about to subside.
A report by Geoffrey Lean, Environment Editor of The Independent, says: The scientists, who studied the composition of the waters of the Atlantic from Greenland to Tierra del Fuego, found that they have become "very much" saltier in the tropics and subtropics and "very much" fresher towards the poles over the past 50 years.
This is alarming because the Gulf Stream is driven by cold, very salty water sinking in the North Atlantic. This pulls warm surface waters northwards, forming the current.
The change is described as the "fingerprint" of global warming. As the world heats up, more water evaporates from the tropics and falls as rain in temperate and polar regions, making the warm waters saltier and the cold ones fresher. Melting polar ice adds more fresh water.
Apparently, similar "flips" have occurred before and caused major cold periods in Europe. The article in The Independent explains how:
