[...] 'There’s an even bigger reason to oppose the pipeline, one that should be on the minds of even those of us who live thousands of miles away: Alberta’s tar sands are the continent’s biggest carbon bomb. Indeed, they’re the second largest pool of carbon on planet Earth, following only Saudi Arabia’s slowly dwindling oilfields.
If you could burn all the oil in those tar sands, you’d run the atmosphere’s concentration of carbon dioxide from its current 390 parts per million (enough to cause the climate havoc we’re currently seeing) to nearly 600 parts per million, which would mean if not hell, then at least a world with a similar temperature. It won’t happen overnight, thank God, but according to the planet’s most important climatologist, James Hansen, burning even a substantial portion of that oil would mean it was “essentially game over” for the climate of this planet'.
