**UPDATE: The Cornell paper is now available in final, published format here: “Methane and the greenhouse-gas emissions footprint of natural gas from shale formations.”[PDF]
The Hill reported this morning on a groundbreaking report from Cornell University researchers confirming that shale gas recovered through high volume hydraulic fracturing, or “fracking,” will produce even more greenhouse gases than the burning of coal in the next two decades - a critical window in which society must reduce emissions to combat climate change. While natural gas is often viewed as a “cleaner alternative” to conventional fossil fuels - and is often promoted as a “bridge fuel” by environmentalists and politicians alike - the new Cornell report explodes this myth.
Gas is not just a “bridge to nowhere,” it turns out to be a highway to hell. The Cornell study makes clear that the widely-held perception that gas is the “cleaner” darling of the fossil fuel trio is a myth. With total methane emissions factored in, shale gas turns out to have the greatest climate impact of all the fossil fuels.
Contrary to popular belief, gas is just as polluting as coal in the long term - and far worse in the near term due to the higher warming impact from methane when it is first released to the atmosphere during the controversial fracking stage. This news is certain to rattle policymakers in Washington who have promoted gas as a solution to our energy crisis. The Cornell paper is a game changer, and its release this week should command the attention of everyone concerned about our energy future.
New analysis shows that the science underpinning the global treaty aiming to stop average temperatures rising more than 1.5°C above pre-industrial levels urgently needs more research,...
