Climate change: can the Seneca effect save us?

Climate change: can the Seneca effect save us?

Nothing we do (or try to do) seems to be able to stop carbon dioxide from accumulating in the atmosphere. And, as a consequence, nothing seems to be able to stop climate change. With the situation getting worse and worse (see here for an example), we are hoping that some kind of international agreement can be reached to limit emissions. But, after many attempts and many failures, can we really expect that next time – miraculously – we could succeed?

Another line of thought, instead, has that depletion will save us. After all, if we run out of oil (and of fossil fuels in general) then we’ll have to stop emitting greenhouse gases. Won’t that solve the problem? In principle, yes, but is it going to happen?

The gist of the debate on the future of fossil fuel production is that, despite the theoretically abundant resources, the production rate is strongly affected by diminishing economic returns generated by depletion. This factor forces the production curve to follow a “bell shaped”, or “Hubbert,” curve that peaks and starts declining much before the resource runs out, physically. In practice, most studies that take into account the diminishing economic returns of productionarrive to the conclusion that the IPCC scenarios often overestimate the amount of fossil carbon that can be burned (see a recent review by Hook et al.). From this, some have arrived to the optimistic conclusion that peak oil will save us from climate change (see this post of mine). But that’s way too simplistic.
