Five soundings in national energy policies

China announces peak coal usage. This is fascinating. It may be an ambition that fails by a wide margin, but it is nonetheless a very interesting development, not least for Australia, which is still planning to double coal exports in the next decade.

Spain announces that wind produced more electricity over the last three months than any other source (a first).

The US has been reducing carbon emissions by some surprising amounts, for a variety of reasons (not all of them straightforwardly good).

Meanwhile, UK plans for nuclear renaissance seem to getting further bogged.

In place of a post on nuclear power

Since even before the disaster at Fukushima, I was planning a lengthy post (or series) considering the place of nuclear power amidst our climate and ecological crises. Towards this post, I now have thousands of words and scores of links (as I do on a number of other topics that are too large for me to find the time to address them with anything like the attention they deserve).

As it seems unlikely that I am going to publish these thoughts anytime in the immediate future (given other deadlines), it seemed like a waste if I did not at least point any thoughtful readers towards this discussion between George Monbiot and Theo Simon. Consisting of a somewhat lengthy email interchange over the last few months now published by George on his website, it is is far and away the best exploration that I have found of the some of the key ethical and political issues behind the nuclear debate, which can get often mired in the technical and economic aspects of the question (as important as they each are).

So consider this discussion a primer for the day when I get around to putting forward my own thoughts in public. For those who may be interested to know where I stand, I will simply say that I am deeply sympathetic to both authors. Now go and read the thread.

There are no merely local famines

In a globalised society, there are no merely local famines, or revolutions, or failed states.

Many of our most severe ecological threats converge on the stability of the global food supply. The most explosive consequences of food shortages are not population decline from starvation, but civil unrest and conflict (as well as increasing vulnerability to disease/pandemic). During the 2008 food price spikes, there were riots in sixteen countries. And the most visible political consequence of the 2010 food price spike was the Arab Spring (though again there were protests and riots in many other countries). Yes, of course there are other underlying factors in every country affected, but the spike in the price of bread was the initial spark in nearly every country that saw significant instances of civil unrest in the Middle East and North Africa (MENA). The protests that ultimately brought down governments in Tunisia, Libya, Egypt (and possibly Syria) all had the price of bread as their trigger (as did those in Bahrain and elsewhere). And why were prices so high in 2010? Again, all kinds of systematic reasons (biofuels taking an increasing share, changing diets, speculation, government hoarding in response to an initial rise), but the short term trigger was almost simultaneous crop losses from extreme weather events in Argentina, Australia, Pakistan and Russia (which famously stopped exporting wheat after its six sigma heatwave). Food price spikes are inconvenient in the west, where we spend less than 15% of our income on food, but disastrous in the many places with otherwise somewhat stable governments where large parts of the population spend more like 75%+ of their income on food.

The consequences of political unrest are not confined to the poor country. To pick one consequence: our taxes here in the UK recently went towards funding war in Libya, despite an austerity programme of slashing government services in response to the worst recession since the Great Depression. Refugee flows from all the various places involved have also increased. Major protests in the US and elsewhere this time last year questioned the direction of the present economic order. These explicitly drew both inspiration and organisational links from elements of the Arab Spring before being brutally suppressed - perhaps not as brutally as in Syria, but if you had your eyes open last autumn there was plenty of state-sponsored violence happening against protesters in free(r) countries, much of which was never acknowledged or addressed by the justice system.

This is not at all to claim that climate change "caused" the Occupy movement in any straightforward way, simply to chase one strand of causal links as an illustration of the global implications of crises in a single region.

Failed states have all kinds of knock-on effects on their neighbours and the rest of the world. Think about the extra costs to global shipping due to Somalian piracy (leading to many shipping companies eagerly awaiting the further opening up of Arctic shipping lanes to avoid the area entirely), about the seedbed of terrorism that Afghanistan has represented since the US turbo-charged the factions against Soviet invasion, about the effect on global oil prices (and hence the global economy) of war in Libya (or Iran...), about the ongoing repercussions of the Arab/Israeli conflict partially driven by the planned failure/sabotage of the Palestinian state. And so on. The global system can handle a few failed states, but since it does so by distributing the costs across the whole system (UK taxpayers paying for wars in Libya), it does so by increasing the stress on the system as a whole. Electricity grids are a good analogy here, actually - grids can handle the sudden failure of a certain number of elements in the grid, but do so at the cost of placing the entire grid at greater risk of collapse. Globalisation is a super-grid for economic and political stability: failure in one part can be accommodated by increasing stress across the board. But only to a point.

This is why Joseph Tainter says in the final chapter of his intriguing and seminal book, The Collapse of Complex Societies that there can be no local collapses in a global system. The term "catabolic collapse" is sometimes used, which refers to a collapse in one part of a system becomes self-reinforcing and ends up taking down the whole show (see here for a much more detailed and insightful discussion of this concept by John Michael Greer).

So when you read about the coming food price spike of late 2012 as the effects of the US drought kick in, don't just think about poor Indians struggling to put food on the table, but also think about the $700b-odd the US spends on its military (over $1t on "national security" as a whole), about the possible break-up of the EU (troubles in Greece are complex, but one of the causes/manifestations/worsening of their crisis is the fact that they receive per capita more refugees and undocumented immigrants fleeing struggling MENA countries than almost anywhere else in the EU and it has seen a big jump in recent years), about deforestation in Indonesia and elsewhere (which is linked, in complex ways, to food prices), and so on.

Global crises require global (as well as local, provincial, national, regional) responses. We can't simply pull up the drawbridge and hope to weather the storm.

Tropical fish in Tasmania, and other stories

Australian waters: Climate change is measurably affecting marine ecosystems in Australian waters, including tropical fish being seen near Tasmania.

Ocean health index: The health of the global oceans has been rated, and given a 60/100. That's (still) a pass, but not very impressive, and most of the indicators are heading south. I'm not persuaded by every aspect of this study (the tourism section, for instance, just seems daft), but mainly it is about trying to set a baseline against which future ocean health can be measured. So the absolute score is probably less important than whether it rises or falls in future.

Carbon and farming: Australian farmers leading the way? I admit I still don't have much of a handle on the details of agricultural practices and carbon sequestration. Yet my impression is that it can only ever be a sideshow, since any carbon sequestered remains in the active carbon cycle, albeit in a phase of slightly reduced activity when compared with the carbon in the upper oceans and atmosphere. Whatever the place of agricultural practices, the centrepiece of any carbon strategy has to be leaving the vast majority of fossil hydrocarbons buried deep underground. This is the only place where excess carbon can be safely stored more or less permanently.

Food crisis: Letter from Jeremy Grantham, a fund manager with his finger on the pulse of where the real threats to the global system lie. Hint: they converge in the stomach.

Flooding: 750 million to be vulnerable to flooding by 2025 in rapidly developing Asian cities, according to the Asian Development Bank.

Hot water: Thermal power stations need cooling water to operate, yet they return that water to its source at a higher temperature than they take it. This means that when rivers and lakes get too warm for marine creatures to live, plant operators and regulators face a choice between power cuts and dead fish (and potentially ruined ecosystems). Even plants using ocean water are not immune. This is a growing problem in a warming world. Solutions include moving away from thermal power plants (thermal plants are those that rely on a source of energy being used to boil water in order to drive turbines and so include coal, gas, oil, nuclear and solar thermal) or building air cooling towers so that the heated water is not returned to the waterway.

Economist vs physicist: A dinner conversation. I linked to this piece in a recent post on growth, but it's worth mentioning again on its own.

Overfishing: Plenty more fish in the sea? The NEF has calculated that the UK has just exhausted the annual productivity of its domestic fisheries and effectively relies on imports of cod and haddock for the rest of the year...

Overconsuming: ...on almost the same day that humanity exhausted its annual budget of global resources.
H/T Donna.

Whistling in the dark

Coral reefs: More than 2,600 marine biologists have signed a Consensus Statement on Climate Change and Coral Reefs, warning of the unprecedented challenges faced by coral reefs from warming, acidifying and rising oceans (due to CO₂ emissions), overfishing, sedimentation, pollution and habitat destruction.

Coral reefs (again): A world without coral reefs is coming, probably much sooner than you think, according to ANU ecologist Roger Bradbury, who thinks the statement mentioned above is a form of collective denial. "It’s past time to tell the truth about the state of the world’s coral reefs, the nurseries of tropical coastal fish stocks. They have become zombie ecosystems, neither dead nor truly alive in any functional sense, and on a trajectory to collapse within a human generation."

Perverse incentives: Why the US Farm Bill just encourages more of the same mistake.

US Drought: the largest agricultural disaster area ever declared, covering more than half the lower 48. This US summer has been off the charts, but on our present trajectory even the hottest summers of the late 20thC will be cooler than the coolest summers of the mid-late 21stC in much of the inhabited world. And you don't want to know what the 22ndC then has in store, since if we get that far, warming is unlikely to stop there.

Chernobyl: It's not over yet. Half the exclusion zone around Chernobyl is forest, mainly highly flammable pine forest, radioactive flammable pine forest. A major fire could send radioactive particules high into the atmosphere and across much of Europe. Again.

UK floods: It didn't take much foresight to see that cutting the budget for flood defences was not a smart move in a nation predicted to get wetter. And the victims are not confined to dwellers in low-lying houses.

Australia in denial: Joe Romm's popular climate blog highlights the precarious position of Australian climate policy, where the tiny baby steps so far made could soon be undone. From one perspective, the current climate legislation might actually be functioning as a distraction, given its lack of ambition yet the tepidness of popular support for anything stronger. But I suspect that the repeal of the legislation would only shift public opinion further into the sand.

Symptom, threat, feedback

LA Times: Bark beetles - a climate change symptom, threat and feedback. Due to warmer winters, a parasitic beetle that swarms pine trees in North America is multiplying rapidly across much of the west of the continent and has "already destroyed half the commercial timber in important regions like British Columbia".

Stephen Leahy: Forest fires to double or triple in a warmer world. Another symptom, threat and feedback.

Guardian: Rising seas will put 12 of 19 UK nuclear sites at risk of flooding. Once more, a symptom, threat and (insofar as one form of lower carbon energy generation is put at risk and thereby taken offline) feedback.

Bill McGuire: The surprising link between climate change and volcanoes and earthquakes . Until recently, it was thought that at least a few natural disasters could be considered still "natural". But this geophysics professor claims otherwise. The link is in the weight of melting ice. So much ice is now melting (or is likely to soon be) that the shifting weight on the earth's crusts could spur increased volcanism and earthquakes. Symptom, threat and feedback.

Carbon Brief: Ocean acidification proceeding ten times faster than any point in the last 300 million years. Symptom (of high carbon dioxide levels, if not climate change directly), threat and feedback (insofar as rising acidity reduces the capacity of the oceans to act as an atmospheric carbon sink). The threat here is large. According to this paper, left unchecked, we are likely on course for another marine mass extinction.

Yahoo: A piece of better news. US dream homes turning green. More than half of US homebuyers consider energy efficiency and other environmental considerations to be important in the selection of a potential purchase.

The Bureau of Meteorology and CSIRO have published the State of the Climate 2012, an update on climate observations from an Australian context. It is summarised here. A summary of the summary: greenhouse gases, land and ocean surface temperatures and sea levels are all still rising. Australia is still heading towards a significantly hotter, drier and more flood-prone future.

Five ways to beat the banks

On Monday, I mentioned the documentary Inside Job, which detailed the ways greed, shortsightedness and ideology caused a partial meltdown of the financial industry in 2008. Despite official reassurances, the radioactive material from these events is not safely secured, but continues to poison an ever wider part of the world.* If you have seen the documentary and share something of my anger, you might also share something of my feelings of frustration and impotence. When the scale of the problem is so large, and the corruption of key institutions so widespread, there is no single silver bullet. Especially for those of us outside the US, the issues in the documentary feel even more distant, as we can't vote for a representative promising change.**
*I realise I haven't written on Fukushima yet. A post on nuclear power is coming, one day...
**And who then does nothing about it. On this, as on many fronts, Obama has been deeply disappointing. I can't say I didn't warn myself.

So what can we do? We may not singlehandedly reform or overthrow the vested interests that created the mess, but we can live lives that point to another way. I have listed a few random suggestions, but would also love to hear more.

1. Repent of the love of money. Delight yourself in the goodness of God and open your eyes to the false promises made by wealth. Reject the idea that gaining more is at the heart of your identity or life, or ought to be at the heart of our political vision of life together. This one is foundational to all the others.

2. Reduce your debt. The apostle Paul tells us to "owe nothing to anyone" (Romans 13.8). The power of the banks is debt-fuelled, and never more so than in the last couple of decades. Perhaps there may be times when certain kinds of debt can be justified; but not when debt is used to fuel needless consumption, or goes beyond one's likely means to repay, or results in driving major life decisions ("I need to work long hours to pay off my mortgage"). For us, this has meant deliberately stepping off the property ladder and not using credit cards - almost everything is now paid in cash or, if we have to, then with a debit card.

3. Join the global movement calling for a Robin Hood Tax - also known as a Tobin tax, after the Nobel laureate who first suggested it forty years ago - that would place a tiny tax on financial transactions in order to make short-term speculative transactions less attractive. The money raised would ideally be earmarked for development aid and climate action, but the existence of the tax as a disincentive to rampart speculation is a distinct question and doesn't depend on where the money would be spent. This campaign is gaining significant traction in Europe, though relatively little in the US. The UK response is key as to whether it grows (and would likely pull in the US, if the previous link is correct) or stagnates. This point can be expanded to include supporting any other genuine attempts to reform the financial system.

4. Take your money from a big multinational bank and put it somewhere else, such as a local credit union or co-op bank. In the UK, try The Co-op Bank. I'd love to hear any recommendations in Australia, since we'd like to switch banks there too. Of course, not all banks are equally bad, but it is difficult to find a large multinational bank where your money won't be financing the arms trade, fossil fuel expansion, environmental degradation and so on.

5. As a church, let us not neglect to encourage, disciple and discipline our members who work in major financial institutions. I asked a while back whether Christians can be bankers, and my tongue was only slightly in cheek. Usury is condemned in scripture and throughout Christian tradition (until the last couple of centuries, when it has been redefined as lending at extortionate interest, rather than simply lending at interest). This is a large topic (and the subject of an upcoming post), but the church needs to ask these questions once more today, particularly in the context of the systemic abuses found in such enormous concentrations of power. When tax collectors asked John the Baptist "Teacher, what should we do?", he didn't tell them to quit their job, but gave the radical advice, "Collect no more than the amount proscribed for you" (Luke 3.12-23). What is the radical advice the church is to give our present day "tax collectors", that is, bankers?

Every second of every day

Greenland is losing around 9,000 tonnes of ice every second. But we're doing our best to mitigate this problem by removing 9-10,000 tonnes of fish from the ocean every hour. And, of course, by dumping 62,500 tonnes of heat-trapping emissions into the earth's atmosphere every minute. The radiative forcing of the carbon dioxide human activities have put in the atmosphere is the equivalent of adding the energy of more than ten Hiroshima bombs every second.

Climate Central: Extreme events related to climate change threaten three US nuclear facilities.

Guardian: UK oil and gas rigs creating spills at least once a week in 2009 and 2010. Remember, the UK claims to have some of the world's highest standards in regulation of off-shore drilling safety. Now take these operations into freezing Arctic waters, where microbes won't be so quick to deal with spills as there were in the tropical waters of the Gulf of Mexico, and where extreme conditions prevent the kind of response available there. Arctic drilling is doubly suicidal: It brings new risks to relatively untouched ecosystems and ensures more greenhouse gases in our atmosphere for thousands of years. And the only reason these waters are opening up to this exploitation is the decline of the sea ice caused by the combustion of fossil fuels in the first place.

Grist: In the worst drought in Texas history, 13.5 billion gallons of water used for fracking. Fracking is the controversial process used to exploit reserves of shale gas, a fossil fuel touted in some circles as a cleaner alternative and as a silver bullet solution to US energy security, but which is worse than coal or conventional oil when gas leaks are included (since natural gas is a very potent greenhouse gas and degrades over time into more carbon dioxide), has been associated with the poisoning of groundwater, and which may well prove commercially unviable much faster than expected according to a recent NYT report (while Stoneleigh offers an even bleaker outlook).

Independent: The plight of the big cats. According to Dereck and Beverly Joubert, leading big cat conservationists, "There were 450,000 lions when we were born and now there are only 20,000 worldwide. [...] Leopards have declined from 700,000 to 50,000, cheetahs from 45,000 to 12,000 and tigers are down from 50,000 to just 3,000."

CP: Food prices hover at historic highs.

IPS: Rising temperatures melting away food security. The impacts of climate change on food production are not limited to heat stress on crops (which may suppress global yields by 5-10% per degree of warming), but also include disruptions to precipitation patterns (i.e. floods and droughts), inundation (or salination) by rising sea levels, loss of glacial melt water (a critical factor, according to this article), increased erosion and shifting distribution of pests and invasive species.

Yale360: Wasting phosphate. "It takes one ton of phosphate to produce every 130 tons of grain, which is why the world mines about 170 million tons of phosphate rock every year to ship around the world and keep soils fertile. [...] We could hit “peak phosphorus” production by around 2030. [...] Presently, there simply are no substitutes for phosphorus."

Reuters: As CO2 levels rise, land becomes less able to curb warming, claims new study in Nature.

Mongabay: The unexpected effects of removing top predators. Another new Nature paper claims that "The loss of these animals may be humankind’s most pervasive influence on nature".

If Brazil has to guard its rainforest, why does Canada/U.S. get to burn its tar sands?

Bill McKibben: If Brazil has to guard its rainforest, why does Canada/U.S. get to burn its tar sands? McKibben has joined with ten other prominent US and Canadian activists and scientists in calling for large-scale civil disobedience over a proposed new pipeline to deliver Canadian tar sands oil to the US.

SMH: The deadliest form of food fight, perhaps the best short piece in a mainstream media outlet on this topic. The Carbon Brief has a useful list of links on climate change and food security (more links are here).

Guardian: At the same time as they put forward a "what peak oil?" report, the UK Government had a second, far less rosy, peak oil report compiled a few years ago. It was not published, until now.

Scientific American: a three part series on the links between climate change and extreme weather. Part One. Part Two. Part Three. Politicians and pundits may pontificate and procrastinate, but the insurance industry takes this very seriously, with more places becoming uninsurable.

Oxford University: Elephant numbers have halved in the last forty years across protected areas in West and Central Africa.

Climate Central: Extreme events related to climate change threaten three US nuclear facilities. Of course, the usual caveats apply to attribution, but the point remains: nuclear has been widely touted as a low-carbon baseload energy solution, yet we are entering an increasing unstable world (climatically, ecologically, and most likely economically and politically). Is it really so wise to build nuclear plants that require rich, stable governments and predictable weather?

CP: Senator Inhofe, perhaps the most outspoken critic of climate science in US politics (a stiff contest), was forced to cancel his appearance at the flagship denier conference due to being "under the weather" after swimming in a blue-green algae bloom exacerbated by drought and a heatwave in Oklahoma. I hope he gets better soon.

Telegraph: warming oceans cause largest marine migration in two million years.

BBC: World's oceans in "shocking" decline. I recently attended a popular open-air lecture by a marine biologist who was presenting unusual creatures from the Norwegian Sea. It was a lighthearted lecture illustrated with a variety of critters and curios in small tanks. During question time afterwards, I asked what changes were evident in the ecosystems she studied. Within seconds of beginning to answer, she was fighting back tears and had to cut short her response.
