Twenty Nile rivers, and other stories

Water stress: By 2025, to feed growing populations, the world will need to find extra fresh water equivalent to the flow of twenty Nile rivers.

Extreme weather: Bill McKibben ponders just how strange this year has been.

Junk food: George Monbiot concludes that a possible link between Alzheimer's and poor diet might be more than sensationalist media spin.

Heat: 2013 tipped to break more records. With a good chance of an El Niño forming in the coming months, combined with the ongoing warming trend from greenhouse gases, next year could be one for the record books. At least until the next El Niño...

Mangroves: Per hectare lost, mangrove destruction is three times worse for greenhouse gas emissions than deforestation.

NB The following articles are eighteen months out of date, but I neglected to post them earlier and they are interesting.
Malthusians beware: Blame the World Bank and IMF (amongst others) for famine in the Horn of Africa, but don't blame overpopulation.

Deep sea fishing: Is any deep-sea fishing sustainable? The short answer is "almost none". Deep-sea fisheries tend to regenerate very slowly, given the small amounts of energy entering the system. Many of the creatures down there are older than your grandmother.

Organic farming: It can be more profitable than conventional farming over the long term, even if organic premiums drop by 50%.

Climate panic: What we can all be doing about climate change. The Onion nearly always hits the key issue on the nose.

Peak when? We've already passed it

ArsTechnica: When is peak oil? We've passed it. Welcome to the downslope.

CP: How much of recent global warming has been caused by human activities? Most likely more than 100%. How can we have caused more than 100% of something? Without human activity, it is likely that we would have experienced a slight cooling trend and so our activities are primarily responsible for both overcoming this natural trend and the observed warming.

NYT: A case study in overfishing - the collapse of jack mackerel in under a decade. A single super-trawler theoretically has the capacity to catch more jack mackerel annually than the most optimistic estimate of the global sustainable catch. The UN Food and Agriculture Organization estimated (based on 1998 data, now hopelessly out of date) that global fishing fleets "are 2.5 times larger than needed." The latest estimate of total global subsidies for fishing fleets (back in 2003) was US$25 billion to $29 billion per annum (mainly in fuels). Let us therefore choose between fish and the fishing industry; we cannot save them both.

Physorg: Wheat can't stand the heat. A new study published in Nature Climate Change found that "a 2.0 Celsius increase above long-term averages shortened the growing season by a critical nine days, reducing total yield by up to 20 percent."

NASA: Greenland, the world's northern mirror, is rapidly growing dimmer, with some areas seeing a drop in reflectivity of almost 20% in a few years.

Stephen Leahy: Toxic pollution is a public health problem on a similar scale to malaria. A new study claims that more than 100 million people have their productive life span shortened by an average of 12.7 years. Some of the causes may be encircling your finger, resting in your pocket or illuminating your eyeballs right now, though the victims may well live on the other side of the world.

Onion: Scientists reveal how to achieve sustainability overnight, though wisely leave open the policy questions.

The end is nigh? Apocalyptic thought and our present distress

Apparently, the apocalypse has already come and gone. Did you miss it?

The relation of apocalyptic thought to our present and likely future distress is an interesting and complex question, not easily answered in a few sentences. I've recently been reading a book edited by Stefan Skrimshire titled Future Ethics: Climate Change and Apocalyptic Imagination, which I mentioned back here. As is usual in an edited collection of essays, quality and relevance vary considerably, but the theme is an important one. How do our images of "the end" shape our understanding (or misunderstanding, as the case may be) of climate change?

For some activists, the pace and scale of anthropogenic climate change on our current trajectory represents an existential threat to the present order of the biosphere, including the human order of a globalised industrial civilisation of almost seven billion and rising. The language of apocalyptic is borrowed in order to try to gain some traction with policy-makers and the public. It matters not whether this borrowing represents a reflexive reliance on a thread of thought with its roots in religious discourse or the deliberate appropriation of concepts and tropes that still inhabit our imagination and so which will resonate widely. The goal is to induce an emancipatory shock, a recognition of our situation as extreme, a justification for emergency measures that disrupt the usual flow of commercial, political and social life with a radical reordering.

Some Christians, noting the borrowing of apocalyptic language by activists, are inclined to ignore the whole thing as another human attempt to claim control of even how the world is going to end. Instead, affirming that the end is in God's hands alone, they argue that any claims of humanity bringing about the end by our own efforts (even inadvertently) must be treated with extreme suspicion.

Personally, while it is difficult to get a good grip on the magnitude of the threat represented by climate change without recourse to some very strong language, I think that it is best to remain agnostic about the relationship between our preset distress and threats and the divine promises relating to ultimate realities. It may be that there is some link, but there is no particular reason in my opinion to think so. Even if our actions lead to the downfall of our way of life and the utter transformation of our society into something so different that in hindsight it is appropriate to speak of industrial civilisation having experienced a self-induced collapse, this need not be the end of the world. To use a line that is growing increasingly common, the end of the world as we know it is not necessarily the end of the world.

And where this cuts the mustard for me is that sometimes apocalyptic thought can become a lazy way out of ethical deliberation. Apocalyptic becomes lazy where it is in the service of a fatalism that assumes our destiny is doomed by the greater power of nature (whether acting blindly, under its own authority as a personified (and angry) mother earth, or as the instrument of God's inexorable judgement) or which conversely rejects the possibility of social self-destruction in principle. In each case, the future is seen as closed and human actions as ultimately irrelevant, in which case, let us eat and drink for tomorrow we die. It can also be lazy where it is used to create panic and a desperate acceptance of whatever medicine is closest to hand. This is a kind of non-emancipatory shock that stuns the hearer into passive acceptance of the salvific social, economic and/or political solution that swiftly follows the apocalyptic account.

Denying knowledge of the relationship between our time and time's telos keeps open the space for neighbourly care. It does this not by rendering apocalyptic inscrutably distant ("since we can't know when the end will come, then let us ignore the coming of the end altogether"), but constantly relevant. In Christian apocalyptic, the hidden meaning of history is revealed to be the stage of divine action, not in competition with human action, but as the previously unknown judge and liberator of human action. Since the day of divine judgement approaches like a thief in the night, unbidden and unobserved, the wise servant knows that her actions are made more weighty, not less. Instead of paralysing fear or enervating schadenfreude, she is liberated to conduct her faithful service in reverent hope of divine vindication. By such acts, she is not heroically securing the future; saving the world (or the present world order) is not her motive or modus operandi. Instead, she trusts that because the hour of her vindication approaches, she has time to prepare, to reflect with prudence on her ability to be a blessing in the limited time she has received. Waiting patiently, she need not dread the outcome of history, but is free to love her neighbour as an instantiation of her wholehearted love for the master with what strength and wisdom she has received. It may be that the immediate future holds suffering, even vast suffering, but not yet the end of all things. In which case, her actions undertaken in hope are not in vain; they are secured by the promise of the resurrection, and thus they are freed from the impossible burden of having to deliver her own life or the continued existence of her society.

And so, there is a sense in which the apocalypse has indeed already come, in the sense that apocalypse means "revelation", an unveiling of what was hidden. After Christ's coming, Christian believers now see the world and its future in a new light. No longer do the dark shadows of anticipated difficulties leave us blindly stumbling along in denial, distraction, desperation or despair. Once relieved of the responsibility to pursue survival above all else, we see the future as a stage on which faithful words and deeds may witness to the redemption of history through the cross and resurrection, and to the coming renewal of all things.

Can we feed ten billion people?

By popular demand, my link dump posts will continue.

Jeremy asks the $64,000 question (ok, so you can add a few more zeroes to the value of that question due to inflation): can we feed ten billion people? He also answers the question: yes and no.

Another Jeremy wonders: what has nature ever done for us?

Bryan reviews a new book co-authored by John Cook (of Skeptical Science fame) on climate change denial. The book makes the point that there are different kinds of denial and that one kind is simply doing nothing with the knowledge that we have.

"I just want my child to go to a good school." Chris Bonnor points out the effects of this mindset.

Ross Cameron offers some reflections on the royal wedding: "The vows are uttered in public because they are so outrageous they have to be witnessed. In lives bombarded by change, there is something incredibly attractive in the idea of making a promise for life."

Mike Wells encourages us to stop being Australian (especially if we actually are).

What do philosophical arguments sorely lack? Referee hand signals.

Deep impact of the loyal opposition

Being a loyal opposition can sometimes have a deep impact: Republicans vote against another Obama bill.

And Mike wants us to know that being criticised doesn't mean we're being persecuted for the gospel, it might just be because we're - well, I'll let him say it.

In case you're short on things to read

Eric ponders Animality and the Word of God: where to draw the boundaries between human and non-human animals and what the theological import of that relationship is. He also posts one of my favourite T. S. Eliot poems, which happens to be relevant to the discussion.

Kevin highlights the real problem with genetically modified (GM) food. It's not that it might be poisonous to our bodies, but that it is toxic to our body politic.

Dana offers a a case study in scientific integrity. Though this is his first foray into the Guardian, I've read quite a bit of Dana's writing and he knows what he's talking about (he's also now posted a further analysis of the replies to his Guardian piece). RealClimate recently published a piece with a similar theme but taking an example from a very different field.

Richard wonders whether individual action is pointless, given the scale of the challenges we face. His answer: our actions may not make a difference, but our example might. An excellent paper going into much more detail on the inadequacy of merely personal lifestyle changes can be found here.
H/T Chris Taylor.

Mongabay asks "What's so wrong with palm oil?", and answers in great detail.

Greenfyre wonders what if there had been no BP oil spill? He offers a perspective which was later mirrored by The Onion: ensuring that all the oil reaches its desired destinations is also an ongoing catastrophe of an even larger scale.

And Jeremy compares our present need for rapid and radical social change with what was achieved in the UK during WWII:
"There is no underestimating the scale and pace of change that happened during the war. Coal use dropped by a quarter, general consumption fell by 16%, car use dropped 95%. Sacrifices were made, but as people ate less and often ate better, levels of health and fitness rose accordingly. Infant mortality and the suicide rate fell, and spending on entertainment was one of the few areas that grew."

More doom and gloom

Asian floods affecting more people than the 2004 Indian Ocean tsunami, plus the 2005 Kashmir and 2010 Haiti earthquakes combined says UN.

Russian heat wave unparalleled in 1,000 years and could kill tens of thousands of people. What is the global cost of Russia's heat wave? When you take into account the highest cost of wheat caused by Russia's cancellation of all wheat exports for the rest of the year, it runs into billions.

But before we begin pitying Russians too much, this piece of lunacy is one of the most depressing things I've heard this week.

The largest iceberg seen in almost fifty years recently calved off Greenland. Arctic melt this year is likely to be second or third worst on record, though will very much depend on prevailing weather conditions over the next few weeks. You can follow it here. But a soot cloud from burning Russian peatland could prove to be a wild card.

Fire and rain: how can we tell when extreme weather is linked to climate change?

Commodity speculation: the price of bread depends on the whims of Wall St, not just the productivity of farms. But remember that "for each 1 degree Celsius rise in temperature we can expect a reduction in grain yields of 10 percent".

Big coal will continue to ensure US climate inertia, and without US momentum, the rest of the world will only reach small-scale and thoroughly inadequate agreements.

But at least we are cutting our throat more slowly in the Amazon.

Finally, perhaps the worst news of all comes from the Onion: Ecological disaster as millions of barrels of oil safely reach port.
