Study: We Have to Leave Fossil Fuels Where They Are or Climate Change Will Reach Dangerous Levels

It may seem like a no-brainer, but now there’s scientific evidence to support the idea that if humans want to avoid catastrophe, we’ll have to stop tapping into underground fossil fuels.

The Guardian:

Vast amounts of oil in the Middle East, coal in the US, Australia and China and many other fossil fuel reserves will have to be left in the ground to prevent dangerous climate change, according to the first analysis to identify which existing reserves cannot be burned.

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.
