Carbon damage cumulative

Re: Containing climate change saves us, not Earth, Sept. 4

Peter Gorrie’s column cited my essay but somehow missed its relevant point. Cutting down global fossil fuel consumption by, say, 20 per cent will have no long-term effect on either the Earth or “us” (i.e. on human beings 10 generations hence) because the carbon stress on the atmosphere is cumulative.

What matters for both is how much of the (finite) fossil fuel reserve you burn, not how fast. Whether people will burn the entire amount is yet to be determined, of course, but the long-term danger to “us” from their doing so is fundamentally constrained by supplies in the ground.

No such constraint exists for the danger of warfare in about 60 years time when oil begins to tighten for good. I personally think that managing this latter problem needs to be a major component any serious energy/environment conversation.

Just to drive the point home, the Athabasca oil sands, which should still be very productive then, would be a particularly juicy target for countries possessing no oil themselves. Names need not be named.
