Designed for yesterday's climate, and other stories

Climate adaptation: Trillions of dollars of infrastructure is designed for yesterday's climate (and sea level, for that matter). In warmer temperatures, railways buckle, highways crack, asphalt melts, cooling ponds overheat, electrical grids overload. "In general, nobody in charge of anything made of steel and concrete can plan based on past trends".

Groundwater depletion: Almost one-quarter of the world’s population lives in regions where groundwater is being used up faster than it can be replenished".

Arctic sea ice: Sea ice decimated by huge Arctic storm. There are all kinds of things going on here and the full effects of the week-long storm in the Arctic are yet to become apparent. Why do we care about a storm in the Arctic? Haven't they happened before? Yes, but not with sea ice this thin. Arctic sea ice is considerably thinner than at any time in recorded history, being up to 70% thinner during the summer months than it was back in the 70s. Thin ice is able to be broken up and moved around by large storms more easily. Without the protective cover of ice, storms also churn up the water more, mixing the very cold, fresher surface water (colder and fresher since it is just under the ice) with the warmer, saltier water further down. Warmer, saltier water is much more effective at melting ice.

Biofuels: George Monbiot laments once more the crazy logic of biofuels, which take food out of the mouths of the poor in order to make the rich feel less guilty about a problem to which it is probably a net contributor, rather than any genuine help.

US Drought: The future of drought. "Indeed, assuming business as usual, each of the next 80 years in the American West is expected to see less rainfall than the average of the five years of the drought that hit the region from 2000 to 2004."

Extinction: North American freshwater fish are going extinct at 800 times the background rate.

Does nature have a price? and other stories

Pricing nature: George Monbiot highlights the myopia of attempting to include "ecosystem services" within mainstream neoliberal economic thought. The initial government report noted that some of the services provided by natural ecosystems "may in fact be infinite in value". You don't say.

Ten Billion: A "play", reviewed here and here, in which noted Cambridge scientist Stephen Emmott plays noted Cambridge scientist Stephen Emmott. The only set is a recreation of his messy Cambridge office and the drama is Emmott delivering a lecture on our current predicament. describes himself as a "rational pessimist" and lays out the daunting, perhaps impossible, task before us in the coming decades where we face multiple converging crises. He concludes that the only rational way forward is radical cultural change with widespread embrace of lower consumption and fewer children (this is pretty close to what I think, with nuances regarding children), but thinks it is not going to happen (this is also basically what I think, though with all kinds of reasons why it is still worth trying). Given that those who will hear this are those willing to pay through the nose for a night of "theatre" more disturbingly horrifying than any fictional film, it's probably better to avoid reading too much into fact that all performances are sold out. Attempts such as this to piece together the various disparate pieces of information that float around the internet and scientific journals are to be valued. That people come away terrified ought to be entirely unsurprising. What is needed is a moral vision capable of surveying such a situation and finding reasons to throw ourselves "once more unto the breach, dear friends, once more".

Australian coal: A victory as one proposed coal plant is shelved.

Hunger games: Coming soon to a future near you. Future heat, drought, food costs and global unrest. I have long been saying that such secondary and tertiary effects of climate change are at least as dangerous as any direct physical effects, though they may not generate headlines that mention climate.

Planetary boundaries: "Approaching a state shift in Earth's biosphere", a recent paper in Nature includes this in its abstract: "Localized ecological systems are known to shift abruptly and irreversibly from one state to another when they are forced across critical thresholds. Here we review evidence that the global ecosystem as a whole can react in the same way and is approaching a planetary-scale critical transition as a result of human influence."

Solastalgia: The word is a neologism coined by psychologist Glenn Albrecht in 2003 and is gaining some recognition. It refers to nostalgia one feels for a place being lost even while you're still there, a homesickness while you're still at home, but home is becoming less hospitable. In Albrecht's own words, it is "emplaced or existential melancholia experienced with the negative transformation (desolation) of a loved home environment". I think it is a useful concept, even if I'm not convinced by the etymology.

Extreme weather: Extreme heat events experienced in many places in recent years are very, very unlikely to be unrelated to climate change. A new study by James Hansen on the attribution of extreme weather events does not use models, but is a statistical study based on observed changes that argues that the increase in what used to be extreme events (three standard deviations above the 1950-80 average) to now cover something like 10% of the globe's surface at any given time (rather than about 0.1% during 1950-80), is strong evidence that such events are vanishingly unlikely to not be related to climate change.

Overheated economy: Temperature rises correlate with declines in economic indicators and political stability, at least in developing nations. Good thing we're not expecting any discernable pattern in global temperatures over the next few decades and centuries then.

The West in Flames: The US West and Southwest is projected by most climate models to get hotter and drier. This has all kinds of implications, but this article by the author of A Great Aridness summarises the implications for trees and wildfire. It's not pretty.

400ppm CO2: Last time CO2 levels were this high. A study investigating conditions 15 million years ago found that "The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit (2.8-5.6ºC) higher than they are today, the sea level was approximately 75 to 120 feet (22.9-36.6m) higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland".

Droughts and flooding rain

A couple of years ago, I used to notice - amongst the usual flotsam and jetsam of half-baked semi-truths, muddled confusion, conspiracy theories, ideological axes, pay-per-comment outright deception and opportunistic spin that passes for much of online climate science dissent - some commenters mocking the idea that a warming world might bring both more droughts and more floods. Now some managed to get past the initial intelligence test by realising that one location might get wetter while another becomes drier, but the second hurdle was realising that the mainstream prediction is (and has been for some time) that in some instances, increased droughts and increased flooding might be likely to occur in the same location.

But today - after the severe Australian drought of the naughties being followed by the wettest 24 months on record, a rare hosepipe ban and widespread drought in England followed by the wettest April and June on record and last year's record Mississippi floods prior to recent reports of grounded barges from river levels 15m lower than a year ago - I don't seem to hear that comment much anymore.

A warming world doesn't just mean a hotter world, but one capable of all kinds of greater extremes.

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.

I will show you fear in a handful of dust

Groundwater depletion. A new study has calculated that the biggest single contributor to sea level rise over the last fifty years has not been melting ice from Greenland or Antarctica, nor melting glaciers, nor even the expansion of the oceans as they warm, but groundwater depletion. This helps to plug a previously puzzling hole between the observed rate of sea level rise over recent decades and estimated contributions from these other sources. Of course, there is an even bigger problem in many places that results from taking groundwater at a rate faster than it is replenished: running out. For three decades, Saudi Arabia used to export wheat grown in its deserts with water extracted from fossil aquifers (i.e. groundwater that fell as rain thousands of years ago and unlikely to be replaced anytime soon). In the last few years, its wheat production has collapsed and is expected to cease entirely by 2016. As a result, it is buying up productive land in Africa, which results in various other problems: dispossession of traditional owners (who may lack adequate documentation of land ownership), corruption of government officials involved in a lucrative business, reduction of local food stability and so on.

Economic collapse? An update to the 1972 Club of Rome study done by researchers at MIT predicts global economic collapse by 2030 on our present unsustainable trajectory. Much discussed, debated and derided at the time, the computer predictions of the 1972 publication The Limits to Growth, have been tracking well with historical data over the last few decades and their timeframe of very serious ecological and resource problems by 2030 do not need to be substantially revised, according to the new study.

Biodiversity decline: EU farmland bird numbers have dropped by 50% over the last thirty years, largely due to farming policies.

2011 CO2 emissions update: John Cook outlines IPCC and IEA scenarios for different emissions trajectories we could follow. Note that the very best (and most difficult) ones still involve major disruption and difficulty in a harsher and less predictable world. They are also likely out of reach without radical and rapid shifts in the global political and economic climate.

UK Climate Policy: George Monbiot traces the latest watering down of UK climate legislation. The UK's Climate Climate Act passed in 2008 with very close to unanimous support, making it the first piece of national legislation setting targets for greenhouse gas emissions reductions in the world. When originally introduced in late 2007, the bill called for a 60% reduction by 2050, but this was increased to 80% on the urging of NGOs, church groups and a Royal Commission.

Great Barrier Reef: The UN has warned that the reef's World Heritage status will be downgraded to "in danger" if Queensland goes ahead with a slew of further port developments to expand the coal and natural gas industries. This article helps to lay out the political context and puts the debate in context, distinguishing between short and long term threats to the reef. It is quite possible to lose the wood of carbon emissions for the trees of maritime traffic. While a major accident would be a disaster, having an increasing number of coal ships successfully reaching their destinations ensures a long term catastrophe through warming and acidifying oceans. Australia's recently announced major marine reserve expansion, while praiseworthy, will do little to save the reef.

WA Forest collapse: "ecosystem change can be sudden, dramatic and catastrophic". Western Australia is rapidly losing its (remaining) forests. The south-west of Australia has experienced some of the most obvious changes in precipitation anywhere in the continent, with a fairly sudden step-change occurring around 1970: "Groundwater levels have fallen up to 11 meters in some forested areas, with larger decreases in populated areas."

Dried up, drowned out

Climate change is a moral issue.

The lifestyles of (most of) the richest 10% or so of the globe comprise the vast majority of anthropogenic carbon dioxide emissions. This includes anyone with an annual income above about £10,000. These extra emissions are raising CO₂ levels, thereby creating a dangerous, potentially catastrophic, legacy for countless generations to come. Carbon dioxide continues to affect climate for thousands of years. Our actions are significantly decreasing the habitability of the planet for humans and presently existing ecosystems. The ones who suffer the most are those who have done least to contribute: the poor, the young and unborn, and other species. Given that we've known about this issue for decades, there is really little excuse for continuing to pass the buck to those who come after or indulging in delay while we hope for a techno-fix to appear. The basic atmospheric chemistry was grasped in the 19th century; since the 1950s we've suspected a problem; since the 1970s we've had a pretty good idea that it was likely a problem; since the 1980s we've had solid evidence; since the 1990s, alarming evidence; and over the last decade the outlook has only grown bleaker.

We enjoy unnecessary luxuries at the cost of others' suffering, livelihoods and lives. That's a moral problem. Another way is possible. Let us embrace it with joy.

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."

What's that got to do with the price of bread?

The warmest UK spring for 350 years and the second driest for 100 has left the southeastern UK in drought. Water restrictions are in place in much of France and the government has set aside €700 million to support struggling farmers, while crop losses will be widespread in Germany too. Indeed, low water levels in major rivers could shut down French nuclear plants as the heat in 2003 did. The southern US has its own problems, with an estimated US$4 billion in losses due to drought already this year, despite the recent heavy flooding on the Mississippi nearby. Drought in China had left shipping on the Yangtze stranded and four million with trouble finding water until recent downpours now threaten floods in some areas. And this follows within twelve months of the Russian heatwave that was six standard deviations above the average and led to wheat exports being cancelled until recently, floods in Pakistan that displaced around twenty million people and decimated crops, while those in Queensland caused billions of dollars in lost crops.

These disasters combined with high oil prices (and no likelihood of them falling significantly barring a further worsening of global economy), an increasing share of fertile land being diverted into growing largely pointless biofuels, declining water tables (more than half the world's people live in countries where water tables are falling), a growing demand for land and water intensive western-style diets in the rising Asian middle class, soil degradation removing an area the size of Greece each year from the world's arable land, declining improvements in yields from agronomy (where something of a plateau seems to have been reached in many places as farmers catch up with scientists), and a volatile commodities market with cash looking for the next quick profit and we have a perfect recipe for the very kind of event that climate scientists, ecologists and economists have been warning about for some time: food price spikes. The UN Food and Agriculture Organisation (FAO) has calculated a Food Price Index since 1990 and the last six months have seen figures rise to their highest since tracking began.

It might be frustrating for us in the UK if the price of bread goes up and we can't afford our holiday to Northern Africa (not that we're going this year; drought-stricken France it is then), but it is a bit more than an inconvenience or a disappointment in places where up to 80% of income is spent on food. It is a recipe for hunger, disease and social unrest. The last dramatic spike in 2008 led to riots in thirty countries and the government of Haiti being overthrown. The spike that has continued since early this year has already played a part in the Arab Spring and is pushing tens of millions back into malnutrition.

This is what climate change looks like (at least for now - remember we are only 0.8 degrees into what may well be a 4 degrees plus experience). Not that every hot day or drought or flood or snow storm can be blamed on us, but that our actions have affected the system to a degree that overall productivity of our agricultural system is made less reliable (one recent study claimed that our changing climate has already put a 5.5% dent in wheat yields), threatening in turn the political system. Climate change is not the only pressure on the food system, but it is the wild-card in the pack of predicaments. Another disturbing development is that projections for expected food production may need to be downgraded in light of another recent study that found that higher carbon dioxide levels contribute less benefit to crops than previously thought.

Rising population and dietary changes mean that food requirements are projected to double by 2050. There are bright spots of opportunity, but the target is looking increasingly out of reach.

A recent report released by Oxfam predicted a doubling of food prices by 2030, which has led to a flurry of media analysis (I found this case study to be particularly illuminating of the systemic problems in how we currently do things).

What are we to do in light of this? All kinds of things. But we can begin by taking a closer look at the food on our plate and becoming interested in where it has come from, what it cost (socially and ecologically) to get it there and what alternatives are already available to us. If we pray "give us this day our daily bread", we cannot take food for granted.

2010: the Earth strikes back?

"Earthquakes, heat waves, floods, volcanoes, super typhoons, blizzards, landslides and droughts killed at least a quarter million people in 2010 — the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined."

- AP: 2010's world gone wild: Quakes, floods, blizzards.

Much of the deadliness can be attributed to human actions: building in dangerous areas, building with inadequate materials, reducing natural mitigation systems (e.g. deforestation in Pakistan worsened the effects of the terrible flooding there) and, of course, disrupting the global climate through our emissions. Perhaps even the year's most deadly single event (the Haiti earthquake) may be linked to deforestation.

It is therefore quite appropriate to question whether such events ought to be called "natural" disasters (far less blamed on an "act of God").

Water: too little or too much are both bad

A new study investigates the future of drought (and it isn't pretty). Note that when reading the images in this study, figures of -4 and below are considered "extreme drought", rarely experienced before now. Meanwhile, the Amazon is currently experiencing its worst drought in almost fifty years.

At the other end of the world, Greenland ice loss is accelerating. And more on Greenland: the plugs in the bathtub.

Pakistan is not the only place to have suffered record floods this year. Over seven million people in Pakistan remain without permanent shelter as a result of the flooding that began over three months ago.

And linking water to fossil fuels: the water cost of Canada's tar sands.

Hoover Dam and Lake Mead: a strange coincidence

Hoover Dam between Arizona and Nevada was a landmark in civil engineering. At its completion in 1935 it was the largest concrete structure in the world (and was the first single structure to surpass the total masonry of the Great Pyramid at Giza). It took about five years to complete and now holds back Lake Mead, the largest water reservoir in the USA and crucial for the water supply of much of the south west (about 25 million people). Its capacity is more than fifteen times that of Lake Burragorang behind Warragamba Dam in Sydney.

The Hoover Dam Bypass (a.k.a. the Mike O'Callaghan – Pat Tillman Memorial Bridge), opened to pedestrian and cycle traffic yesterday and is the longest single arch concrete bridge in the western hemisphere. Taking about five years to construct and soaring over the Hoover Dam, it makes for some impressive photos and removes the need for traffic to use the two lane road across the top of the dam wall, a slow section of a major infrastructure route and a potential target for a vehicular bomb (large trucks have been banned from the road since not long after the attacks of 2001).

On Sunday (the day before the bridge opened), Lake Mead fell to its lowest level since it was filled in the 1930s, due to a complex range of factors, most notably water management over-allocation and persistent drought. Declining precipitation in the south west USA has for some time been predicted by most climate models as a result of anthropogenic climate change.

So within a twenty four hour period, a major new bridge opened to allow more traffic (and so more carbon dioxide emissions) over a dam whose reservoir is being emptied (partially) by climate disruption resulting from those emissions. Irony?
