A blown nose, a blown world environment - and why some people confuse the two


It’s one of the few times I’ve managed seriously to annoy a motorist while stationary on my bike. One dark winter night a couple of years ago in London, I blew my nose while waiting at traffic lights. But, lacking the time to fish out a handkerchief, I snorted onto the road.

Traffic queuing in Miami Beach. Some of these cars might look to you
like polluters - but the drivers might think snot more offensive
It can’t, I accept, have made for a pretty sight. But the reaction of a woman in a car behind still surprised me. Leaning on her horn, she gesticulated her disgust wildly. The irony instantly struck me. In contemporary society, it’s regarded as entirely acceptable to make urban journeys in vehicles that spew out gases that will pollute and warm the atmosphere for a century or more. Clear one’s airways of a little biodegradable mucus, however, and one puts oneself entirely beyond the pale.

But the more I’ve thought about it since, the more I’ve realised the Outraged Driver of Kennington Park was exhibiting attitudes to environmental pollution and emissions very common in industrialised societies across the world. She regarded herself as having the right to an environment treated as she wanted. She felt perfectly entitled to criticise others’ treatment of that environment. Her attitudes, however, made no reference to any ultimate yardstick about the fate of the world environment as a whole.

I’ve said before on this blog that I am nothing like as exercised about environmental issues as many people assume cyclists are. I enjoy the overall sense that cycling is a rational way to get around – that it makes good use of scarce city space, that it contributes very little to congestion, that it keeps me healthy, that it’s enjoyable. It’s part of that picture that each trip contributes hardly at all to overall carbon emissions. But the environmental factors form only one corner of the overall scene.

That said, I regularly currently confront vivid evidence of the seriousness of the world’s environmental problems. Parts of the Hudson River Greenway, which I use for nearly half my daily commute in New York City, were under five feet – 1.6m – of water at the height of Superstorm Sandy in October. Many scientists think such extreme weather events are becoming more common as the world’s climate changes. Yesterday, I cycled down to Coney Island, one of the parts of the city worst-hit in the storm, to help clear out a vacant lot that was under seven feet of water on the night the record high water swept up New York Bay. The weather was so unseasonably mild that on the way home it felt oppressively warm. There’s an undeniable sense that climate change is becoming a more urgent, practical issue, which anyone who takes an interest in the wider world needs to address.

A modern, fuel-efficient container ship:
a surprisingly clean way to import food
Yet few of the responses to the issue rise much above the level of honking one’s horn at behaviour one dislikes. I’ve frequently heard it averred, for example, that it’s good for the environment to eat local, seasonal produce. But very few of the people who claim that can give a detailed accounting of local, seasonal produce’s carbon costs – even though the ships that import food to temperate, rich-world countries use remarkably little fuel. It’s certainly far from clear that buying fruit imported on such a ship from a country where it grows easily is worse than eating greenhouse-grown local fruit that’s come to the farmer’s market in a small, inefficient van.

Railway lobbyists also make blanket claims that their transport mode is invariably more environmentally friendly than using a car. But, while that is undoubtedly true for a well-filled train in the London rush hour, it isn’t true for a nearly-empty train spewing diesel fumes into the air to move a couple of passengers to their destinations. When I lived in the UK, my most regular long-distance rail journey was London to Chester on a Super Voyager diesel-powered train. I would give a rueful smile as I remembered that the complex, heavy but fast train issued much the highest level of emissions per seat mile of any UK train model. It was, on average, a better environmental bet to take the train for that journey than to hire a car. But the margin was not very wide at all.

There are some similarly questionable attitudes towards cycling’s environmental performance. I’ve recently come across a number of attacks on cycling’s environmental record that point out, for example, that manufacturing bikes produces carbon emissions – an undeniable point, which makes it clear that one shouldn’t replace one’s bike more often than necessary. Such attacks generally go on to point out that fuelling a bike involves carbon emissions. There are carbon costs to moving the extra food that cyclists eat that they otherwise wouldn’t. And the food generates emissions that the Outraged Driver of Kennington Park would presumably dislike even more than mucus – in the form of methane, a far more potent greenhouse gas than the carbon monoxide from cars.

The most entertainingly bonkers attack of this kind I’ve encountered was a recent blogpost from an Ian Pearson who claims to give “a more accurate guide to the future” (How can he tell?) on bikes’ carbon performance. Cycling might well, Mr Pearson accepts, produce next-to-no carbon emissions per kilometre. But, when a cyclist rides in traffic, he asserts, the extra carbon cost of attending to accidents – and the effect on cars’ carbon performance of slowing down then accelerating to overtake cyclists – probably produces so much extra carbon that it would have been more environmentally friendly for the cyclist to go by car.

This new Ford pick-up truck concept will be more fuel-efficient
when it launches than its current equivalent.
But that won't make its drivers necessarily
friends of the environment.
The common thread between all these questionable assertions is that they treat the environment’s fate as an abstract matter – as susceptible to objective observation as the question of how to live the good life or whether God exists. People who profess concern about the environment often have a bias in favour of things that appear traditional and prepared without the benefit of complex, modern scientific advances. Many assume locally-produced food must be better for the environment because, well, it feels as if it should be. Similarly, people who are relatively unconcerned about environmental issues have a tendency to work back from their own behaviour to a spurious justification. “My car’s not as polluting as it might be” gets rationalised into “I am environmentally virtuous”. “I don’t like manoeuvring around these cyclists” becomes “these cyclists are bad for the environment”.

Yet, for the effects of air pollution and global warming, it is ultimately possible to estimate the effects objectively. Scientists now have a reasonable idea of what kind of damage different levels of carbon emissions produce. It is even possible to come up with rough figures for the costs that different kinds of emissions impose on wider society.

In a rational world, governments would now be rushing to take the guesswork out of estimating environmental impacts. Food products would include a label detailing the carbon costs of their production and include a tax reflecting them. Air tickets would include something similar, while the carbon costs of burning each unit of fuel would form a clear and distinct part of the petrol price at the pump. Past experiments with introducing new prices for previously-free goods – such as the Central London Congestion Charge – suggest consumers would move swiftly away from the most environmentally damaging behaviours towards less damaging ones.

I am robustly confident that such an exercise would make far clearer than the existing tax systems in most rich-world countries that bikes have big environmental advantages over most other transport modes. It is hard to imagine that the change would not significantly increase cycling levels.

the kind of decisive action on the environment
that many governments are taking
The challenge, however, is that such a move would upset groups commonly supposed to be hugely influential – motorists, regular air-travellers and the owners of big houses – while pleasing few others. Governments consequently lay down a few cycle lanes on the roads, offer some subsidies for electric cars, meet some of the cost of better home insulation and generally gesture vaguely in the environment’s direction. Action that would make a real difference remains resoundingly untaken.

Yet that, perhaps, should be no surprise. Across the industrialised world, governments depend on the votes of people as inconsistent as the Outraged Driver of Kennington Park, Ian Pearson and, come to that, each of us reading (and writing) this blog. There’s no firm consensus yet among all those people in favour of firm action to rein in the galloping horse of the worsening global climate. That many governments consequently seem little more rational on the issue than an irritated, late-night driver may be sad – but it is depressingly understandable.

Whatever the weather, cycling's proved a post-Sandy surprise

Most mornings, as I cycle to work, I smile to myself as it occurs to me that my children and I both start the day by looking at the American flag. But, while the Invisible Visible Children are taking the Pledge of Allegiance at the start of their school day, I’m looking to the flag for a more practical reason. The stars and stripes that fly from the top of the Brooklyn Bridge tell me which way and how strongly the wind is blowing. Since I moved to New York in the summer, it’s been the direction and strength of the wind on the main section of my morning cycle commute – north up the Hudson River Greenway – that’s been the biggest single determinant of how quickly I can make the journey. A following wind can get me there as much as five minutes faster than the prevailing headwind, I estimate.
The Hudson River Greenway: wind challenge

It’s one of countless ways that moving to New York has reminded me of how cycling makes me far more aware than any other way I might travel of nature’s forces. The summer heat is hotter here than in London, where I lived before, and the humidity higher. The rain is less frequent but the cloudbursts more intense. The winter, when it comes, will be more likely to bring very low temperatures and heavy snowfall. But the last week has made me realise that it’s only my constant awareness of the conditions around me that sets me apart from my fellow New Yorkers. Living for the most part on islands on the edge of a bay vulnerable to storm surges, we’re all to some extent going about our business at the pleasure of the elements. And it’s turning out that when nature really pays us back for the presumption of living in such an exposed position bicycles have a rather important role to play.

It was when I saw the mixture of embarrassment and pity on the CEO’s face that I realised I would need to change some of my cycling routines to fit New York’s weather. It was late June, I had just cycled briskly to my office in nearly 40 centigrade heat amid high humidity to encounter a colleague unexpectedly asking me to join his meeting with an important visiting chief executive. I had ridden – as I used to do in London – in my work shirt with the sleeves rolled up. In the greater New York heat, I was dripping with perspiration. My shirt was damp enough that my chest hairs were visible. I did my best to make myself look respectable. But, when I entered the meeting, it was clear I was still looking rather freakish. “Looks like you’ve done a hard day’s work already,” the CEO said. The next day, I started cycling in a T-Shirt and changing on reaching the office.

The heat and humidity, however, are nothing compared with getting caught in a proper New York downpour. Having cycled regularly in rain in London, I thought myself ready to face the worst a temperate-climate city could produce in the way of rain. Then I set out for home one evening in mid-September amid a deluge that would not have disgraced monsoon-season Chennai. A gutter running downhill on Ninth Avenue had turned into a respectable-sized, fast-flowing, deep river. Every surface was slick with water. The mixture of high humidity, torrential rain and darkness left me struggling to see where I was going. My waterproof jacket became so thoroughly soaked that my BlackBerry, tucked inside a pocket, got fatally wet. It was one of the rare occasions when I regretted the folly of my determination to get about by bike.

9th Street, Brooklyn during Sandy:
the Invisible Visible Man is invisible in this picture for a simple reason
- he wasn't riding when it got like this
As a result of that experience, I resigned myself, when I heard that a tropical storm was approaching New York, to weather that would stop me cycling for a few days. On the Saturday evening before superstorm Sandy hit, I took the Invisible Visible Girl by bike to a friend’s house for a Halloween sleepover. By the time I went to pick her up the next morning, the wind was up enough to send leaf debris stinging into our eyes. By late in the afternoon, as I ferried the Invisible Visible Boy on his trailerbike to a playdate with a friend, I was beginning to doubt the wisdom of being out. Every other means of transport gradually came to a halt too. The Monday was a rare day when I dared not cycle anywhere. I monitored the storm’s progress by walking cautiously down to the canal near our apartment. By the evening, I could see water up to the rooves of nearby buildings where we’d walked around earlier in the day.

But the same surge of water I could see in the canal was devastating many areas I couldn’t see. Water was pouring into subway, commuter rail and road tunnels all round the city. It was pouring through the Staten Island ferry terminal in Manhattan and carrying onto the shore the large ship I would see later in the week beached in Staten Island. It was, in other words, knocking out pretty much every means of transport that depends on any complex electrical or electronic control system. It was even shutting down the pipeline that supplied fuel to the city, laying the groundwork for queues hundreds of yards long to appear by gas stations later in the week.

As a result, I found myself in an unusual position among my colleagues over the next few days, possessed of the one means of transport that enabled me to consider a lengthy commute into Manhattan. I abandoned an initial attempt to reach the office on Tuesday, discovering in still-powerless lower Manhattan the value of the traffic lights whose numbers in New York City I’ve previously decried. But, skirting round the powerless section via Greenpoint and Queens, I found myself back in the office on Wednesday, able to slip past traffic jams and wheel my bike round downed trees. By Friday, I was volunteering to report from Staten Island, putting my bike on the first ferry after the service resumed. I pedalled my way down to bits of the island where the surge had come up to the ceilings of residents’ ground floors. My main thought was that I was fortunate to live in a part of the city where our main moan was a brief Internet outage and a shortage of bread in the shops. While a man had died in his basement in one street I visited in Staten Island, we had never been in serious danger.

But, as I cycled past queues for fuel so long that different gas stations’ lines met each other in the middle and heard anguished stories of islanders’ four-hour journeys to work, I also felt a new appreciation of my bike. New York largely depends on transport systems so overstretched that every extra journey puts a strain on them. I needed little more than a solid surface under my wheels and made few demands on anyone else as I used it.

I don’t know how long my bravado in the face of bad weather will continue into the coming, probably harsh winter. The weather is already making it feel more comfortable to be inside than out. But the past week has made me appreciate afresh the flipside of a cyclist’s vulnerability to the elements. I might have felt dangerously exposed at points on Sunday – more exposed than someone using other means of transport. Yet that also reflects cycling’s simplicity – the thing that’s allowed me to keep skipping round the city in a week when others have spent hours in traffic jams or waiting for shuttle buses.
The Manhattan Bridge bike lane:
this climb's a Mont Ventoux to a novice

New York’s most pressing problem is that thousands of my fellow New Yorkers remain without heat, light and, in many cases, shelter as the weather gets colder. But some hopeful signs are emerging from the post-Sandy gloom. The most impressive is undoubtedly New Yorkers’ willingness to help each other – the pile of donations I saw in church this evening, ready to go from well-off Brooklyn Heights a couple of miles down the road to inundated Red Hook. But there was also something stirring about watching the inexperienced cyclists on the Manhattan Bridge on Friday. One knew so little about his cruiser bike he was riding with the kickstand down. Others felt the need for a breather only a third of the way across the bridge. All seemed possessed of a sense that their work or some other business was so important that their physical limitations or experience of cycling shouldn’t stand in the way.

As the city rebuilds, one can only hope that at least some of those forced converts experienced at least a little of the satisfaction of experiencing and overcoming the power of nature while cycling. Having seen the vulnerability of the city’s overstretched transport systems to disaster, I harbour at least a hope that some of them might choose to stay on their bikes and keep battling the elements with me.
