CLIMATE CHANGE WILL DESTROY US

Climate change over the next 20 years could result in a
global catastrophe costing millions of lives in wars and natural
disasters.
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.
'Disruption and conflict will be endemic features of life,'
concludes the Pentagon analysis. 'Once again, warfare would
define human life.'
