The worst-case scenarios on climate change envisaged by the UN two years ago are already being realised, say scientists at an international meeting.
he meeting was also addressed by Lord Stern, the economist, whose landmark review of the economics of climate change published in 2006 highlighted the severe cost to the world of doing nothing.

He said that if the world was to warm by 5C over the next century, there would be dramatic consequences for millions of people. Rising seas would make many areas uninhabitable leading to mass migrations and inevitably sparking violent conflict.

Lord Stern: 'The Economics of Climate Change' underestimated the risks
"You'd see hundreds of millions people, probably billions of people who would have to move and we know that would cause conflict, so we would see a very extended period of conflict around the world, decades or centuries as hundreds of millions of people move, " said Lord Stern.
Dr Rajendra Pachauri, the IPCC chairman, said: "It is extremely encouraging in that the science has moved on from what was possible in the Third Assessment Report.
"If you see the extent to which human activities are influencing the climate system, the options for mitigating greenhouse gas emissions appear in a different light, because you can see what the costs of inaction are," he told delegates in Paris.
Achim Steiner, executive director of the United Nations Environment Programme (Unep), said the findings marked a historical landmark in the debate about whether humans were affecting the state of the atmosphere.
Appropriate technology (AT) is technology that is designed with special consideration to the environmental, ethical, cultural, social and economical aspects of the community it is intended for. With these goals in mind, AT typically requires fewer resources, is easier to maintain, has a lower overall cost and less of an impact on the environment compared to industrialized practices.[1]

The End Of Surburbia
As the population of suburban sprawl has exploded in
the past 50 years, so too the suburban way of life has
become embedded in the American consciousness.
Suburbia, and all it promises, has become the American
Dream. But as we enter the 21st century, serious
questions are beginning to emerge about the
sustainability of this way of life. The consequences
of inaction in the face of the global environmental
crisis are enormous. What does Oil Peak mean for North
America? As energy prices skyrocket in the coming
years, how will the populations of suburbia react to
the collapse of their dream? Are today's suburbs
destined to become the slums of tomorrow? And what can
be done NOW, individually and collectively, to avoid
The End of Suburbia ?
Scientists are a step closer to making environmentally-friendly 'magnetic' refrigerators and air conditioning systems a reality, thanks to new research published today in Advanced Materials.
