The economics of volcano eruptions

Now that a small eruption has caused serious economic headaches to the north of Europe, (JUST the airlines are talking about losing $200 million euros a DAY) we are seeing some sober reflections of our vulnerabilities.

What links the banking crisis and the volcano? 
We rely globally on over-complex, over-strained systems. Act now, or wait for the much more brutal corrective of nature

Man proposes; nature disposes. We are seldom more vulnerable than when we feel insulated. The miracle of modern flight protected us from gravity, atmosphere, culture, geography. It made everywhere feel local, interchangeable. Nature interjects, and we encounter – tragically for many – the reality of thousands of miles of separation. We discover that we have not escaped from the physical world after all.

We have several such vulnerabilities. The most catastrophic would be an unexpected coronal mass ejection – a solar storm – which causes a surge of direct current down our electricity grids, taking out the transformers. It could happen in seconds; the damage and collapse would take years to reverse, if we ever recovered. We would soon become aware of our dependence on electricity: an asset which, like oxygen, we notice only when it fails. 
As New Scientist magazine points out, an event like this would knacker most of the systems which keep us alive. It would take out water treatment plants and pumping stations. It would paralyse oil pumping and delivery, which would quickly bring down food supplies. It would clobber hospitals, financial systems and just about every kind of business – even the manufacturers of candles and paraffin lamps. Emergency generators would function only until the oil ran out. Burnt-out transformers cannot be repaired; they must be replaced. Over the past year I've sent freedom of information requests to electricity transmitters and distributors, asking them what contingency plans they have made, and whether they have stockpiled transformers to replace any destroyed by a solar storm. I haven't got to the end of it yet, but the early results suggest that they haven't. 
There's a similar lack of planning for the possibility that global supplies of oil might soon peak then go into decline. My FoI requests to the British government reveal that it has made no contingency plans, on the grounds that it doesn't believe it will happen. The issue remains the preserve of beardy lentil-eaters such as, er, the US joint forces command. Its latest report on possible future conflicts maintains that "a severe energy crunch is inevitable without a massive expansion of production and refining capacity".

For the third time in two years we've discovered that flying is one of the weakest links in our overstretched system. In 2008 the rising cost of fuel drove several airlines out of business. The recession compounded the damage; the volcano might ruin several more. 
Energy-hungry, weather-dependent, easily disrupted, a large aviation industry is one of the hardest sectors for any society to sustain, especially one beginning to encounter a series of crises. The greater our dependence on flying, the more vulnerable we are likely to become. 
Over the past few days people living under the flight paths have seen the future, and they like it. The state of global oil supplies, the industry's social and environmental costs and its extreme vulnerability mean that current levels of flying – let alone the growth the government anticipates – cannot be maintained indefinitely. We have a choice. We can start decommissioning this industry while there is time and find ways of living happily with less of it. Or we can sit and wait for physical reality to simplify the system by more brutal means. more
