I don’t know when global oil supplies will start to decline. I do know that another resource has already peaked and gone into freefall: the credibility of the body that’s meant to assess them. Last week two whistleblowers from the International Energy Agency alleged that it has deliberately upgraded its estimate of the world’s oil supplies in order not to frighten the markets(1). Three days later, a paper published by researchers at Uppsala University in Sweden showed that the IEA’s forecasts must be wrong, because it assumes a rate of extraction that appears to be impossible(2). The agency’s assessment of the state of global oil supplies is beginning to look as reliable as Mr Greenspan’s blandishments about the health of the financial markets.

According to farm scientists at Cornell University, cultivating one hectare of maize in the United States requires 40 litres of petrol and 75 litres of diesel(3). The amazing productivity of modern farm labour has been purchased at the cost of a dependency on oil. Unless farmers can change the way it’s grown, a permanent oil shock would price food out of the mouths of many of the world’s people. Any responsible government would be asking urgent questions about how long we have got.

The challenge of feeding 7 or 8 billion people while oil supplies are falling is stupefying. It’ll be even greater if governments keep pretending that it isn’t going to happen.
