Guest guest Posted March 14, 2006 Report Share Posted March 14, 2006 Sharp rise in CO2 levels recorded By David Shukman BBC science correspondent US climate scientists have recorded a significant rise in the concentration of carbon dioxide in the atmosphere, pushing it to a new record level. BBC News has learned the latest data shows CO2 levels now stand at 381 parts per million (ppm) - 100ppm above the pre-industrial average. The research indicates that 2005 saw one of the largest increases on record - a rise of 2.6ppm. The figures are seen as a benchmark for climate scientists around the globe. The chief carbon dioxide analyst for the US National Oceanic and Atmospheric Administration (Noaa) says the latest data confirms a worrying trend that recent years have, on average, recorded double the rate of increase from just 30 years ago. Mankind is changing the climate Professor Sir David King, UK chief scientific adviser " We don't see any sign of a decrease; in fact, we're seeing the opposite, the rate of increase is accelerating, " Dr Pieter Tans told the BBC. The precise level of carbon dioxide in the atmosphere is of global concern because climate scientists fear certain thresholds may be " tipping points " that trigger sudden changes. The UK government's chief scientific adviser, Professor Sir David King, said the new data highlighted the importance of taking urgent action to limit carbon emissions. " Today we're over 380 ppm, " he said. " That's higher than we've been for over a million years, possibly 30 million years. Mankind is changing the climate " . British Scientist Lovelock Says it's Too Late To Reverse Global Warming By Staff (EUNN) London - James Lovelock, 81, a Fellow of the Royal Society and honorary visiting professor at Oxford University, says it is too late for the world to turn around the damage that's been done to Earth's climate and warned the leading nations to prepare for what he called " living hell " as the earth's climate continues to grow warmer. Lovelock was responsible for the discovery of the global distribution of nitrous oxide and of the chlorofluorocarbons, both of which are important in the stratospheric chemistry of ozone. If a lesser scientist made such a prediction they'd be ridiculed. But Lovelock, now 81, has received a slew of environmental and scientific awards and honours in the US, Europe and Japan. Before this century is over, billions of us will die, and the few breeding pairs of people who survive will be in the Arctic where the climate will be tolerable, Lovelock maintains. According to Lovelock, the world has already passed the point of no return for climate change, and civilisation as we know it is unlikely to survive. The theory holds that the planet has a special way of regulating itself, chemically and atmospherically, of keeping itself fit for life, as if it were a great superorganism; as if, in fact, it were alive. Lovelock, who conceived the idea in the 1970s while examining the possibility of life on Mars for Nasa, has been warning of the dangers of climate change since major concerns about it first began to surface nearly 20 years ago. Now his concerns have reached a peak and have a new emphasis. Rather than calling for further ways of countering climate change, he is calling on governments around the world to begin large-scale preparations for surviving. " I think we have little option now but to prepare for the worst, " Lovelock recently told western governments, " and assume that we have passed the threshold. We will do our best to survive but sadly I cannot see the US or the emerging economies of China and India cutting back in time, and they are the main source of emissions.
