David Strahan thinks global oil depletion will soon spell the end of the Easyride.
Mountaineers are a special class of climate criminal. We clearly have a particular moral duty to protect the icy landscapes we enjoy, and most of us like to think of ourselves as environmentally responsible. But the reality is rather different. When it comes to flying, just like the hordes heading off to the beaches of Magaluf, we remain in stubborn denial about the damage our emissions cause, and carry on regardless.
In a recent three page article for The Independent entitled ‘The Melting Mountains’, Joe Simpson bemoaned the destruction of classic routes in the Alps from melting ice and massive rockfalls, without a single mention of his own airmiles, still less the helicopter fuel used to haul him off the Dru. At a meeting of the Alpine Club last summer, one speaker regaled us with stories from a lifetime of expeditions and slides showing evidence of glacial retreat, without once making the connection. Ed Douglas reports being canvassed about a plan to climb the Seven Summits by a couple of teenagers who apparently had yet to develop a sense of irony. Their campaign - involving at least seven round trip long haul flights - was intended to raise money for an environmental group called Leave No Trace.
There is of course scant chance that climbers will forego their flights voluntarily, but it is now becoming increasingly clear that soon this will cease to be a matter of choice. The fleeting age of the jet-setting pack rat is about to come to an end, not primarily because of climate change, but because of its stealthy companion: oil depletion. Topping out on far-flung hills courtesy of BA or Easyjet will soon be consigned to history because of one apparently insurmountable problem: the peak of global oil production, known in the industry as peak oil or Hubbert’s Peak. These terms are not immediately self-explanatory, but should perhaps be more suggestive to climbers than anyone else. As every ascentionist knows, when you reach the top, there’s only one way to go.
M. King Hubbert was an irascible but brilliant Shell geologist who in 1956 stunned the oil industry by predicting that US oil production would ‘peak’ and go into terminal decline - in either 1965 or 1970, depending on which of two industry estimates of ultimate US oil reserves he employed. At the time he made the forecast, US production was still rising strongly, and the idea that it might soon start to fall was considered outlandish, so the perennially optimistic oil industry laughed with scorn. But he was right: US oil production peaked in 1970, right on schedule, even though half the oil that would ever be produced there was still underground.
Hubbert’s great insight was that oil production in a given region does not ‘run out’ in the way that a car suddenly runs out of petrol, but ‘peaks’ long before the end of the resource has been reached.
This is the result of two critical oil industry facts of life. First, oil is mostly found in deeply buried and highly pressurised reservoirs, and it is this pressure that drives the oil up the well to the surface. But as the oil is produced the pressure falls, meaning the oil comes out ever more slowly as time goes on. Second, in the normal course of events, oil men look for, discover, and exploit the largest oil fields first, for obvious reasons. This means that as production declines in the biggest fields, increasingly the industry has to scrabble around to make up the loss with smaller and smaller fields. Like the Red Queen oil men have to run flat out just to stand still. Eventually, when about half the oil has been produced, the overall rate of production starts to fall. That’s the third oil industry fact of life, so get used to it.
Oil production is now falling in 60 countries around the world - including once mighty producers such as Mexico, Norway, Indonesia, Columbia, Argentina and the UK, where North Sea production peaked in 1999 and has already fallen by more than a third. The only question is when global oil production will follow the same pattern and go into terminal decline. Most sensible forecasts range from about 2010 to 2020, although if the deranged ideologues in Washington or Tel Aviv attack Iran, the crisis will break far sooner. The British government’s official position is that the peak will not come until after 2030, but I consider the oil resource estimates on which this assertion is based to be demonstrably over-inflated. Meanwhile, two of Tony Blair’s closest advisors – Sir David Manning, his key foreign policy advisor during the preparations to invade Iraq, and Sir David King, the government’s Chief Scientific Advisor - believe that global oil production will peak in a decade or less.
On the graph Hubbert’s Peak may not look too challenging a summit, but the relatively sudden reversal from oil production growth to contraction is likely to produce a potentially devastating crisis, because clean alternative fuels will not remotely fill the yawning supply deficit even for road transport, let alone in the air. For instance, figures from the International Energy Agency show that if Britain used all its arable land to grow biodiesel, we could produce only a quarter of our current road fuel consumption - and of course we’d starve. Alternatively, I calculate that if we decided to run Britain’s road transport system on hydrogen created ‘cleanly’ (that is, by electrolysing water using non-CO2 emitting forms of electricity), our choices would be: 67 Sizewell B nuclear power stations; a solar array covering every inch of North Yorkshire; or a wind farm bigger than the entire south west region of England. In the absence of viable replacement fuels, when global oil production stalls, the price of a barrel is likely to soar to unprecedented levels and push the world into deep recession or worse. The last oil shock indeed.
The global aviation industry consumes only about an eighth as much fuel as road transport, but in some ways the problems of replacing jet kerosene are even more intractable. As well as the resource constraints already discussed, there are serious technical obstacles to using clean alternatives in the air. Jet engines could fairly easily be adapted to run on hydrogen, but airframes would have to be completely redesigned to accommodate far bigger fuel tanks. The most likely designs would be of the ‘flying wing’ type, but these are decades away from realization. And biofuels - even if you had enough land - are no use to airlines, since they turn viscous at the low temperatures encountered at altitude, potentially clogging the engines. According to Bob Saynor, a researcher at Imperial College who wrote a paper investigating alternative jet fuels, “In the short to medium term we don’t have realistic and economically viable options”.
As a result, when oil production peaks the consequences will be particularly severe for the aviation industry, which has in any case lost more money since the turn of the century than it has ever made in its entire history. Airlines will drop like flies, and aviation will once again become the exclusive preserve of the rich, if it survives in a meaningful form at all.
Synthetic jet kerosene could be made from natural gas or coal - not in immediate danger of running short - using the Fischer Tropsch process exploited by the Nazis in WWII. However the technology is phenomenally expensive, and the process itself consumes so much energy that the fuels it produces generate up to twice the greenhouse gas emissions of conventional fuels. If coal-to-liquids technology were widely exploited, running out of oil could paradoxically make climate change worse, and this would only accelerate the introduction of climate change policies which will eventually have much the same effect on discretionary air travel as a shortage of fuel.
Personal carbon trading is a system of rationing in which every person’s right to emit carbon (or consume fossil energy, which amounts to the same thing) is steadily reduced every year. It would help combat both climate change and oil depletion, and has already been discussed at the highest levels of the British government; Environment Secretary David Miliband, tipped to run a new Department of Environment and Energy under Gordon Brown, is enthusiastic. For the Tories, Oliver Letwin is said to be an ‘anorak’ on the subject. It would of course be politically explosive, but it is beginning to look as if this is the only way meaningful cuts in emissions can be achieved. The idea has moved quickly – if quietly – up the political agenda, and could be introduced far sooner than anyone expects. Done properly, this would also eliminate mass air travel in fairly short order.
If Britain is to achieve its target of cutting CO2 emissions by 60% by 2050, then every person will have to reduce their total annual emissions from an average of about 10 tonnes of CO2 now to just four tonnes by the middle of the century. Including the effects of radiative forcing, four tonnes is roughly equivalent to one round trip flight between London and Kathmandu, even using traditional jet kerosene, and even if you could fly direct. But if you took that flight in 2050, you would then have no ration left over to cover ground transport or home heat and power for the entire year.
So what should climbers do? The cynical response would be to fly as far and as often as possible to bag all those peaks you dream of climbing before the crisis hits or personal carbon trading really begins to bite. But that would be to corrupt the traditional justification for climbing - ‘because it’s there’ – into one that is utterly selfish and self-fulfilling: ‘because it soon won’t be’. The only responsible and sensible approach is to prepare for the last oil shock by starting to reduce your energy consumption right away, and working out what climbing opportunities remain achievable within a contracting energy budget.
Whether due to oil shortage or rationing, I suspect some kinds of travel behaviour will be eliminated almost overnight: jetting off to Banff, as I once did, with half a hundred weight of ironmongery in the belly of the plane for a single week’s ice-climbing; or belting up the motorway from London to the Highlands just for the weekend. But there will still be plenty of opportunities, especially in the early years, provided the fuel reduction is caused by progressively tightening carbon rations, rather than a paralysing oil shock. The Alps will still be in reach by train or coach, although probably less frequently as time goes on. At home, personal carbon trading will encourage car-sharing: a trip to North Wales might not be so prohibitive with four ration-holders in the car.
Since personal carbon trading will cover all your fossil energy consumption, extreme conservation around the house might allow you to save rations towards the trips you are still desperate to make. For instance I worked out that if I left my TV, hi-fi, computer and other gadgets on standby for a year, the electricity wasted would be enough to drive an electric car over 2,800 miles. That’s enough to cover two round trips from London to Chamonix and another up to Hathersage and back. I wouldn’t recommend trying it in a tiny G-Wiz mind you, but you get the drift.
Some climbing professionals are already preparing for these developments. Phil Coates, an International Mountain Leader and cameraman who runs imagesofadventure.com, has led 25 expeditions to the greater ranges in the past 15 years but now plans to refocus his business almost exclusively on Europe. He reckons that soaring jet fuel prices will soon force climbers to take fewer trips and concentrate on hills closer to home - in the Alps and the new eastern members of the EU such as Poland and Bulgaria - and to get there by train. “You’ll still be able to get your mountain fix in Europe”, he says, “but it’s a no-brainer that the days of long haul mountaineering are numbered”.
But the greater ranges may not be entirely out of reach, if you’re tough enough to follow the example of the late Goran Kropp who in 1996 cycled from Sweden to Nepal carrying all his equipment, climbed Everest, and pedalled home again. When I first heard this story I dismissed it as another crazy stunt in a world with too few genuine challenges left. Today I believe he is the only climber ever to have summited that peak in good style: without supplemental oxygen or hydrocarbons. Climbers should embrace this new ethic voluntarily for the sake of the ice. But even if we fail, it will soon be enforced, one way or another.
SURVIVE THE SHOCK
David Strahan suggests five ways to survive the last oil shock and cut your carbon emissions:
1. Manage your mileage. Cutting daily car use is the best way to reduce your exposure to the last oil shock. Resolve to halve it progressively over five years, by finding alternative ways to make everyday journeys to work, school and the shops. The average British car does about 9,000 miles per year, the average main driver 7,400. If your totals are higher, you need to cut faster. Eventually you may be able to sell your car, and join a car club (www.car-pool.co.uk) for the occasions when you still need to use one. Eventually you may have to. Choose public transport, or better still, buy a bike - and use it.
2. Location, location, location. If you really cannot get to work, school or the shops without your car, you need to lobby your local authority for some decent public transport, or think about moving home. If neither is an immediate prospect, when you next move house, proximity to decent local amenities should be top of your tick list.
3. Wise up, turn down, switch off. Turn your central heating down a couple of degrees and wear another layer. Each 1°C cut should save about 10% off your fuel bill. Switch all electronic appliances off at the socket whenever they are not in use. Computers and their peripherals consume lots of electricity even when ostensibly turned off, never mind on standby. Switch to a green electricity provider such as Good Energy (www.good-energy.co.uk), and if you do nothing else, visit www.oneclickpower.co.uk.
4. Invest in energy saving technology. Solar panels are expensive, and micro wind turbines may not produce anything like their official power rating. But good insulation and draft-proofing is cheap and pays for itself almost immediately, and solar hot water systems (www.nef.org.uk) on a south-facing roof can produce up to half a family’s hot water over the course of a year for relatively little outlay.
5. Retrain for the post-peak economy. The economic impact of the last oil shock will be felt throughout the economy, but some sectors will be hit harder than others: airlines bad, wind turbine engineering good. Retraining now would be a smart move.
