Oil itself isn't the problem. Climate change is about adding the carbon from fossil fuels to the air. If we could magically convert all remaining unburned coal/oil to an enormous cube of polyester, it would more or less immediately put a cap on global warming. Of course it would also cause worldwide famine, but my point is that global warming itself isn't a directly result of the extraction/use of fossil fuels, but specifically the burning of them.
