Coal, not oilsands, the real threat to climate, study finds
Quote:
One of the world’s top climate scientists has calculated that emissions from Alberta’s oilsands are unlikely to make a big difference to global warming and that the real threat to the planet comes from burning coal.
“I was surprised by the results of our analysis,” said Andrew Weaver, a University of Victoria climate modeller, who has been a lead author on two reports from the United Nations Intergovernmental Panel on Climate Change. “I thought (the threat of oilsands emissions) was larger than it was.”
In a commentary published Sunday in the prestigious journal Nature, Weaver and colleague Neil Stewart analyze how burning all global stocks of coal, oil and natural gas would affect temperatures. Their analysis breaks out unconventional gas, such as undersea methane hydrates and shale gas produced by fracking, as well as unconventional oil sources including the oilsands.
They found that if all the hydrocarbons in the oilsands were mined and consumed, the carbon dioxide released would raise global temperatures by about 0.36C. That’s about half the total amount of warming over the last century.
