Oil production (all liquids in barrels per day) in the US and Canada. (From Ron Patterson's blog). Does this rapid growth indicate that the resources are abundant and that all the worries about peak oil are misplaced? Maybe not....
Sometimes, we use a simple metric to evaluate complex systems. For instance, a war is a complex affair where millions of people fight, struggle. suffer, and kill each other. However, in the end, the final result is seen in terms of a yes/no question: either you win or you lose. Not for nothing, General McArthur said once that "there is no substitute for victory".
Now, think of the economy: it is an immense and complex system where millions of people work, produce, buy, sell, and make or lose money. In the end, eventually, we think that the final result can be described in terms of a simple yes/no question: either you grow, or you don't. And what McArthur said about war can be applied to the economy, as well: "there is no substitute for growth".
But complex systems have ways to behave and to surprise you that can't be reduced to a simple yes/no judgement. Both victory and growth may well create more problems than they solve. Victory may falsely signal a military might that doesn't really exist (think of the outcome of some recent wars....), while growth may signal an abundance which is just not there.
Give a look at the figure at the beginning of this post (from Ron Patterson's blog). It shows the oil production (barrels/day) in the US and Canada. The data are in thousand barrels per day for "crude oil + condensate" and the rapid growth for the past few years is mostly due to tight oil (also known as "shale oil") and oil from tar sands. If you follow the debate in this field, you know that this growth trend has been hailed as a great result and as the definitive demonstration that all worries about oil depletion and peak oil were misplaced.
Fine. But let me show you another graph, the US landings of North Atlantic Cod, up to 1980 (data from Faostat).
overfishing" and things like that. It is what was said, indeed (see Hamilton et al. (2003)).
Now, look at the cod landings data up to 2012 and see what happened after the great burst of growth.
overexploitation leads to collapse: people don't realize that by pushing for growth at all costs, they are destroying the very resource that creates growth. This can happen with fisheries just as with oil fields. Then, note also that we have here another case of a "Seneca Cliff," a production curve where the decline is much faster than growth. As the ancient Roman philosopher said, "The road to ruin is rapid". And this is exactly what we could expect to happen with tight oil
