The new work reveals the profound geopolitical and economic implications of tackling global warming for both countries and major companies that are reliant on fossil fuel wealth. It shows trillions of dollars of known and extractable coal, oil and gas, including most Canadian tar sands, all Arctic oil and gas and much potential shale gas, cannot be exploited if the global temperature rise is to be kept under the 2C safety limit agreed by the world’s nations. Currently, the world is heading for a catastrophic 5C of warming and the deadline to seal a global climate deal comes in December at a crunch UN summit in Paris. “We’ve now got tangible figures of the quantities and locations of fossil fuels that should remain unused in trying to keep within the 2C temperature limit,” said Christophe McGlade, at University College London (UCL), and who led the new research published in the journal Nature. The work, using detailed data and well-established economic models, assumed cost effective climate policies would use the cheapest fossil fuels first, with more expensive fuels priced out of a world in which carbon emissions were strictly limited. For example, the model predicts that significant cheap-to-produce conventional oil would be burned but that the carbon limit would be reached before more expensive tar sands oil could be used. theguardian/environment/2015/jan/07/much-worlds-fossil-fuel-reserve-must-stay-buried-prevent-climate-change-study-says
