WHAT HAVE WE DONE?!

'
The World's leading scientists have made a desperate plea to politicians to act on climate change or see civilisation as we know it degenerate into mere survival, banditry, war, chaos and death.

The future therefore means no politicians but also the death of our progeny and the World as we know it!

In what was described as a watershed moment, more than 2,500 leading environmental experts agreed a statement that called on governments to act before the planet becomes an unrecognisable, unpleasant, difficult and in places, impossible – place to live or probably even survive....

At the emergency climate summit in Copenhagen, scientists agreed that "worst case" scenarios were already becoming reality and that, unless drastic action was taken soon, "dangerous climate change" was imminent, with increasing average temperatures will mean huge areas lost to massive rises in sea level, devastated by hurricanes, rainforest's become uninhabitable desert, social unrest, then the forced migration of billions of people from what were their homelands, with fighting, banditry, war and famine flushing away what little is left of civilisation and our children's lives.

In a strongly worded message that, unusually for academics, appealed directly to politicians, they said there was "no excuse for inaction" and that "weak and "ineffective" governments must stand up to the short term concerns of big business and other "vested interests".

Steps should be "vigorously and widely implemented", they said, to reduce greenhouse gases. Failure to do so would result in "significant risk" of "irreversible climatic shifts", the statement added.

The plea came as Lord Stern, the former chief economist of the World Bank whose report two years ago drew attention to the possible results of global warming, told the conference that unless politicians grasped the gravity of the situation it would be "devastating with.... increases in average temperatures of six degrees by the end of the century were an increasing possibility and would produce conditions not seen on Earth for more than 30 million years..... that could mean massive rises in sea level, whole areas devastated by hurricanes and others turned into uninhabitable desert, forcing billions of people to leave their homelands."

He told the summit that politicians continued to underestimate the impact of climate change and that scientists needed to redouble their efforts to get them to understand. "Much of southern Europe would look like the Sahara. Many of the major rivers of the world, serving billions of people, would dry up in the dry seasons or re-route..... what would be the implication? Hundreds of millions of people would have to move, probably billions. What would be the implication of that? Extended conflict, social disruption, war essentially, over much of the world for many decade upon decade"

The Copenhagen conference is intended to publicise the latest research on climate change ahead of December's meeting of world leaders. The United Nations Climate Conference, which will also be held in Copenhagen, aims to draft an updated Kyoto-style agreement on reducing emissions.

Under the Kyoto deal, developed nations have to cut emissions of greenhouse gases by 5.2 per cent below 1990 levels by 2008-2012. However, during the meeting scientists have frequently spoken about how former assumptions about the risks have had to be redrawn. They have repeatedly warned that higher than expected emissions have meant that temperatures will rise at rates far higher than thought just a few years ago. This in turn will lead to disastrous sea level rises, melting of the icecaps and acidification of the oceans.

Scientists warned that the weather will continue to change resulting in destruction of the rainforests, widespread droughts and flooding.

Prof Kevin Anderson, the research director at the Tyndall Centre for Climate Change Research in Manchester, said: "Scientists have lost patience with carefully constructed messages being lost in the political noise. We are now prepared to stand up and say enough is enough."
