“The world only has 10 years to develop and implement new technologies to generate clean electricity before climate change reaches a point of no return,….” “The rate at which we are emitting now, around 2ppm a year and rising, we could expect that that tripping point will reach us in 20 years’ time. That gives us 10 years to develop technologies that could start to bite into the problem.”
Peter Smith, a professor of sustainable energy at the University of Nottingham, theguardian.com, 5 September 2006
