Nog meer wetenschappelijke feiten die bewust genegeeerd worden, terwijl onze politici ons aanvuren nog harder te werken voor economische groei. Opnieuw de Independent: 'Global warming '30 times quicker than it used to be.' Greenhouse gases are being released into the atmosphere 30 times faster than the time when the Earth experienced a previous episode of global warming. A study comparing the rate at which carbon dioxide and methane are being emitted now, compared to 55 million years ago when global warming also occurred, has found dramatic differences in the speed of release. James Zachos, professor of earth sciences at the University of California, Santa Cruz, said the speed of the present build-up of greenhouse gases is far greater than during the global warming after the demise of the dinosaurs. "The emissions that caused this past episode of global warming probably lasted 10,000 years," Professor Zachos told the American Association for the Advancement of Science at a meeting in St Louis. "By burning fossil fuels, we are likely to emit the same amount over the next three centuries."' Lees verder: http://news.independent.co.uk/environment/article345928.ece
