Using your head: why pedestrians need helmets

Canadians take the lead in public safety regulation with a new mandatory pedestrian helmet law coming into effect tomorrow.

Our climate challenge in three numbers

"When we think about global warming at all, the arguments tend to be ideological, theological and economic. But to grasp the seriousness of our predicament, you just need to do a little math. For the past year, an easy and powerful bit of arithmetical analysis first published by financial analysts in the U.K. has been making the rounds of environmental conferences and journals, but it hasn't yet broken through to the larger public. This analysis upends most of the conventional political thinking about climate change. And it allows us to understand our precarious – our almost-but-not-quite-finally hopeless – position with three simple numbers."

- Bill McKibben, Global Warming's Terrifying New Math.

Apart from missing "s" in the title and a dodgy stat in the opening paragraph, McKibben's compelling 5-page piece is a good summary of some important elements of the challenge we face. The bottom line of his three numbers is that, according to our best understanding, if we want at least an 80% chance of staying under the internationally agreed (but still very dangerous) 2ºC limit we can only burn about 20% of our current fossil fuel reserves (not resources, but reserves, i.e. what is known and could be profitably brought to market under present conditions). This is the kind of statistic that can really serve to focus the attention. We need to leave four out of every five known and already profitable barrels of oil, tonnes of coal, cubic metres of natural gas underground.

Of course, the great difficulty is that no one country wants to do anything other than burn every last molecule of fossil hydrocarbon that can be brought to the surface unless all other countries agree to limit themselves also. And when some countries have far larger reserves (and so far more at stake economically in leaving 80% of them in the ground), then reaching such an agreement is basically impossible under present political assumptions. If you look at where the blockages in international negotiations are coming from, then it's no great surprise that these are also the countries with the largest reserves of fossil hydrocarbons: China, USA, Russia, Australia, Canada, various middle eastern states. Countries with tiny (or largely depleted) reserves are the ones at the forefront: small island nations, non-oil-based African nations and the EU (esp UK and Germany, which have historically had huge fossil carbon deposits, but have already burned most of their easily accessible stuff).

And so we are left with an international multi-player game of chicken, with no country wanting to blink first and lose market advantage, ensuring that all countries suffer horrendously as a result. The fact that those with least to contribute to the problem generally have greater vulnerability only serves to entrench both the injustice and the intractability of the issue.

The slim silver lining in recent extreme weather in the US is that it might bring home to US voters and policymakers that there are no winners in a game of chicken. Even if others are going to suffer more and sooner, the US is far from immune, especially to precisely these kinds of threats (droughts, wildfires, heatwaves, water stress). Russia is facing its own wildfires and floods. China has had large areas in drought almost constantly for the last five years and a flood this week has a death toll that could pass 100. Canada has simultaneously faced deadly floods and serious drought in the last couple of months. Middle Eastern petro-states are all too aware of their dire water situation as they rapidly go from grain exporters to zero wheat production within a decade (Saudi Arabia) after basically exhausting their fossil water. And Australia has all too quickly forgotten its own droughts, bushfires and floods just a couple of years ago.

Further complicating the picture is that it is not simply countries that are making these decisions. Apart from some nationalised oil companies, most of these reserves are held by for profit corporations with very, very deep pockets and who are generally not shy at throwing their weight around, spending up big on lobbying, misinformation and propaganda at every level in order to convince us all that without them we'd be living in caves and that they are struggling to get by in tough conditions.

Yet according to the most recent data, fifteen out of the thirty most profitable companies in the world are directly fossil fuel related (many of the remaining fifteen also have significant, if slightly less direct, links).

1. Gazprom: US$44.5b
2. Exxon Mobil: $41.1b
4. Royal Dutch Shell $30.9b
5. Chevron: $26.9b
8. BP: $25.7b
11. Vale: $22.9b
12. Petronas: $21.9b
13. VW: $21.4b
14. Ford: $20.2b
15. Petrobras: $20.1b
22. China National Petroleum: $16.3b
26. GE: $14.2b
27. Statoil: $14.1
29. Rosneft Oil: $12.5b
30. ConocoPhillips: $12.4b

The bottom line is that until a very wide audience grasps just how dire our situation is and starts to demand something different from our corporate and political leaders, then none of key climate numbers are likely to improve.

For me, the most telling number in McKibben's piece is the one that he doesn't mention. McKibben is an author with a string of respected publications about environmental and economic issues. He was the first popular writer to publish a book on climate change back in the 80s. Yet in the last three or four years he has re-invented himself as an activist after becoming convinced that writing alone is too slow to effect the changes that need to happen. He has built and become the public face of the world's largest climate movement, a movement named after and dedicated to a number: 350. His organisation, 350.org, refers to the highest concentration of CO₂ in parts per million considered "safe" by some of the world's leading climate scientists. We are currently over 390 ppm and rising rapidly. For most commentators, 350 ppm is seen as a pipe dream, an impossibility, well outside the realm of the thinkable, let alone the achievable. International negotiations talk about 550 and occasionally 450, but many commentators think we'll be lucky to stay below 650 and our current path is heading for 750 or significantly higher. In this context, McKibben and 350.org have served as a witness to how far from a just and sustainable world we are currently travelling. And yet here, in one of his highest profile pieces to date, he doesn't mention the number to which he has dedicated the last few years of his life and of which he is a relentless promoter. Is this because he has been so successful in publicising 350 ppm that he felt he could move on? Or because he decided that this idea is now so detached from reality that he needed to lower his sights?

Ecological responsibility and Christian discipleship I: Human planet

This will be the first in three posts giving a slightly modified version of a sermon I delivered a few weeks ago based on Genesis 1. The three posts are as follows:
I. Human planet: Welcome to the Anthropocene.
II. The Community of Creation: Genesis 1.
III. Recycle or repent? Our response.

Human Planet: Welcome to the Anthropocene
We no longer live on the same planet on which we were born. I’m not just talking about the internet and globalisation, or trends in fashion and music. The chemistry of the oceans and atmosphere, the stability of the climate, the diversity and health of ecosystems are all very different to what they were. Human activity over the last handful of decades has altered the face of the globe in ways so profound that it will be visible in the geological record millions of years into the future. The Geological Society of London, which is the UK national society for geoscience and the oldest geological society in the world, is currently considering a serious proposal to declare that we have now left the Holocene and entered into a new geological epoch, called the Anthropocene, named after anthropos, which is Greek for human, because we humans are having such a extreme effect on all the ecosystems and even geology of the planet. I hardly need to tell you that most of it isn't a positive effect.

Think of the most remote places on the planet, places so wild and desolate that none live there. No matter where you picture, human fingerprints are all over the landscape.

You are probably aware that Arctic summer sea ice is in terminal decline and many of us in this room are likely to live to see a largely ice-free Arctic in summers to come. This winter, while we shivered through a December that was 5ºC below average, parts of the Canadian Arctic averaged 21ºC above their long term mean. Permafrost is no longer looking so permanent and some now call it "tempfrost". As it melts, not only are roads and buildings sinking and breaking, but it is releasing more and more of the methane and carbon dioxide that have been locked away for millennia and which will, of course, only make the melting worse.

If the Arctic isn't pristine, then perhaps the mountains, the high Andes and towering Himalayas? Well, again, you're probably aware of the accelerating glacier melt occurring on 95% of all glaciers, including the most remote. And in many places the melt is accelerated when soot particles land from cooking fires and factories land on the ice, darkening the surface and absorbing more solar energy. Indeed, thanks to Julian Assange, we know that the US State Department was told by the Dalai Lama that addressing climate change is a higher priority for Tibet than independence from China.

What about the deep Amazonian rainforest where there are still to this day dozens of uncontacted tribes? Yet first contact for these indigenous groups is most likely to be with loggers. Although deforestation rates have declined from a decade ago, tropical rainforests continue to be bulldozed at a rate of a football field every few seconds. Eighty percent of the world's ancient forests have been destroyed or degraded, half of that has been in the last 30 years.

What about bottom of the ocean? Even there the human fingerprints are everywhere. Deep sea trawling by commercial fishing fleets drags heavy metal beams over the sea floor, crushing and scattering slow-growing deep corals and other creatures and kicking up plumes of underwater dust that can be seen by satellites. And each year, an area twice the size of the continental United States is bottom trawled, scooping up more fish than the ocean can replenish. Four-fifths of commercial fish species are considered by marine biologists to be fully-exploited, over-exploited or have collapsed. On our current trajectory, no commercially-viable fish stocks will be left by the time my daughter turns 40.

Feeling stressed? Breathe in – breathe out – breathe in – breathe out. Every second breath comes from phytoplankton, microscopic plant-like organisms in the oceans that are the basis of the marine food chain and which are the source of over half the planet's oxygen. And yet, there is evidence that the number of phytoplankton has declined by 40% since 1950. I've already alluded to climate change, but did you know that all the excess carbon dioxide in the atmosphere is also changing the chemistry of the oceans? The planet's oceans are on average 30% more acidic than pre-industrial times, more acidic than they have been for millions of years and changing faster than any known previous shift. And they are getting warmer too. Climate change is first and foremost oceanic change, since oceans absorb more than 93% of the extra energy trapped by our greenhouse gas pollution. Oceanic currents are shifting. Sea levels are rising. The climate is warming: 2010 was the equal warmest year at the end of the warmest decade, which followed the previous warmest decade, which followed the previous warmest decade on record. The last 311 consecutive months have all been warmer than the 20thC average.

Seasons are changing. Plants flowering earlier in Spring, migrations and hibernations patterns are shifting. Our actions are shifting rainfall patterns: stronger droughts, more intense rain and snow.

Human actions are responsible for the extinction of about a thousand recorded species. They are just the ones we're aware of. Our best estimates of how many we've actually bumped off falls between twenty thousand and two million. And this is rising rapidly, causing most biologists to judge that we are currently causing the start of the sixth great extinction event in earth's four and a half billion year history.

Since 1970 we have reduced animal populations by 30%, the area of mangroves and sea grasses by 20%, the coverage of living corals by 40% and large African mammals by more than 60%.

Over 60% of major rivers in the world are dammed or diverted. There is five times as much water stored in dams and reservoirs as all the world's rivers put together. We have directly modified three quarters of the ice-free land surface of the planet and currently move more soil each year than the natural cycles of wind and water.

And I haven’t mentioned heavy metal toxins, soil degradation, aquifer depletion, ocean eutrophification, introduced species, desertification, or the trillions of floating plastic particles found in all the world's oceans.

We no longer live on the same planet on which we were born.

And God said to them, "Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea. And over the birds of the air and over every living thing that moves upon the earth."

- Genesis 1.28 (NRSV).

Our passage this morning has been used to justify the patterns of exploitation and acquisition that in our lifetimes have reached such an extent as to have permanently altered the face of the planet. Can we read it again with fresh eyes and see whether it might have good news for us today?
I haven't had time to include links for all these claims, though it's worth noting that they were not first published by Greenpeace or WWF; they are not the scare stories of eco-extremists out to rob you of your fun or set up a world government. These claims appear in highly respected scientific journals – Nature, Science, Proceedings of the Royal Society and so on. Some are still quite fresh and subject to ongoing debate. Most are widely agreed as our best knowledge of our present situation. If there are particular ones you are interested in, I can try to provide relevant citations.

From a great height

"The Harper government is reluctant to impose regulations on 'energy-intensive industries' like the oil sands in the absence of comparable U.S. moves, arguing that to do so would damage Canada’s economic competitiveness."

- From The Globe and Mail.

Developed nations attempting to outdo one another in economic growth are a little like skydivers competing for the highest terminal velocities in free-fall. Refusing to regulate the tar sands because it might damage economic competitiveness is akin to refusing to open a parachute because the other guy might get ahead of you.

What has WikiLeaks ever done for us?

This is a partial list covering some of the abuses of corporate and government power revealed by WikiLeaks over the last few years. Is any of this information in the public interest? Does this record indicate an exclusively anti-USA organisation? Are these revelations the work of terrorists? Would anyone prefer for the world not to have known all these abuses? During its four year history, WikiLeaks has exposed the following:

• 217 cases of UN peace-keepers being accused of sexually abusing and impregnating girls in eastern Congo.

• Trafigura, an African oil company, caused widespread illness through a toxic gas dump, and then tried to suppress this being published in the Guardian through a secret "super-injunction", in which the press cannot even report the existence of an injunction.

• US forces killed hundreds of innocent civilians at checkpoints in Iraq.

• The "secret bibles" of Scientology, normally only available to initiates for very large sums of money.

• The designation of some prisoners at Guantanamo Bay detention camp as off-limits to the International Committee of the Red Cross, which the US military had previously denied.

• Details of the corrupt rule of the Arap-Moi leadership in Kenya, who were involved in US$3 billion dollars of fraud. They were subsequently defeated at the next election.

• Sarah Palin used a private Yahoo email account to send work-related messages, in violation of public record laws.

• Corruption amongst politicians in Peru over oil contracts, which resulted in the prime minister's resignation.

• More than 15,000 civilian deaths in Iraq that had previously been concealed by the U.S. government.

• A video showing a U.S. army helicopter slaughtering Reuters journalists and Iraqi children in cold blood.

• Al-Qaeda's deadly exploitation of children in Iraq.

• Irregular activity at Kaupthing Bank in Iceland, with large sums of money being loaned to bank owners and other debts were written off, precipitating the Icelandic financial crisis, the collapse of all three Icelandic banks, the breakdown of a coalition government and the indictment of a former prime minister.

• US Department of Defense Counterintelligence Analysis Report from March 2008 detailing how to marginalise WikiLeaks.

• US soldiers used Iraqi civilians as human bomb detectors.

• Illegal government wiretapping in Canada.

• The CIA kidnapped an innocent German and tortured him for months, then attempting to stop Germany from arresting its operatives.

• The US State Department instructed its diplomats to break international treaties by gathering biometric and other personal data on senior UN figures.

• The US has pressured the UK government to break a treaty on cluster bombs by turning a blind eye to bombs stored at US bases on UK territory.

• Australian government web filtering to prevent access to child pornography and terrorist sites extended to a range of other legal sites, including Wikipedia entries, Christian sites, a tour operator and WikiLeaks itself.

• DynCorp, a US company, hired young boys to dance for Afghan police in a social context usually linked to pederasty.

• Shell's corruption and influence in the government of Nigeria.

• The US wrote Spain's proposed new copyright laws.

• US suppression of Spanish court cases involving US figures accused of torture and extradition.

• Pfizer used dirty tricks to avoid clinical trial payout.

Pentagon and Bundeswehr on peak oil

I know it's been out for a while, but back in April, the Pentagon released a report on global energy outlook that turned a few heads. Here are some key quotes:

"By 2012, surplus oil production capacity could entirely disappear, and as early as 2015, the shortfall in output could reach nearly 10 million barrels per day.* [...] While it is difficult to predict precisely what economic, political, and strategic effects such a shortfall might produce, it surely would reduce the prospects for growth in both the developing and developed worlds. Such an economic slowdown would exacerbate other unresolved tensions, push fragile and failing states further down the path toward collapse, and perhaps have serious economic impact on both China and India. [...] One should not forget that the Great Depression spawned a number of totalitarian regimes that sought economic prosperity for their nations by ruthless conquest."

*To get a sense of the scale of this warning, the total global consumption is around 85 million barrels per day.

It is also worth considering the recently leaked draft report of a think tank employed by the German military (known as the Bundeswehr), which advises that in order to maintain its supply, Germany may need to revise its foreign policy: friendlier to Russia, Saudi Arabia and Iran; a little less friendly to Eastern Europe and Israel. It also warns of the dangers of restricted supplies of energy in a globalised marketplace, when oil is involved directly or indirectly in the production of over 95% of food and industrial goods: "In the medium term the global economic system and every market-oriented national economy would collapse [... making] room for ideological and extremist alternatives to existing forms of government."

The challenge of the next two or three decades is going to be avoiding massive political instability and resource wars while expanding global food production in the face of rapidly declining soil health, water stress and an increasingly unstable climate, all with ever increasing shortfalls in energy production. Current rates of oil field decline mean that we need to bring a new Saudi Arabia online every three years just to maintain current production and current rates of demand growth (largely in the developing world) mean that on top of that we need another Saudi Arabia every seven years. If you're banking on Canadian tar sands or US shale oil making up the shortfall, you're dreaming. Or perhaps, starting a nightmare, since these would only cover part of the likely shortfall and would singlehandedly ensure we'd be at the worse end of climate predictions. The extraction of tar sands and shale oil are slower, more energy and water intensive, more expensive and especially more polluting (of both water sources and the atmosphere) than conventional oil extraction.

We face massive technical, economic, ecological, social and political challenges in the coming years. I currently don't see how widespread unrest, price shocks, rising international tensions and increasingly desperate grabs at remaining resources are not going to be a large part of the likely storyline of the next few decades.

If the significant risk of such scenarios is not factored into our thinking, I suggest we're out of touch with reality. It is no virtue to have one's head in the sand.
