In Scientific Consensus on Maintaining Humanity’s Life Support Systems in the 21st Century: Information for Policy Makers (pdf) makes for depressing reading. We’re well on the way to stuffing up the planet’s climate, we’re causing species extinctions at a rate not seen since an asteroid hit the planet 65 million years ago and wiped out the dinosaurs, we’ve transformed 40% of the ice-free land on the planet through farming, logging and building towns and cities, we’re polluting the atmosphere and oceans, and population and resource consumption are growing fast.
All of these impacts feed on each other, and make it more likely that the planet will pass through tipping points that lead to irreversible changes. It’s not enough to work on just one issue — we have to work on all of them at the same time, and quickly. The longer we leave it, the more expensive and difficult it will be to prevent crisis turning into disaster. “Delaying even a decade may be too late,” the statement warns.
This is a huge challenge for the political process around the world. Progress on climate change — a problem first identified in the 1980s — has been pitifully slow. Economic and political inertia, exploited by industries that stand to lose if carbon emissions are cut, have made meaningful international action all but impossible to achieve. Thirty years of fine talk and empty promises mean that we’re now staring down the barrel of irreversible and highly damaging climate change.
It’s difficult to be optimistic that the world is suddenly going to sit up and pay attention. There’s too much money to be made, and influence to be bought, by carrying on with business as usual. Ultimately the planet will find a way to deal with humanity’s impacts if we don’t, and the outcome is unlikely to be pretty.
Pathological consumption has become so normalised we scarcely notice it
By George Monbiot, published in the Guardian 11th December 2012
There’s nothing they need, nothing they don’t own already, nothing they even want. So you buy them a solar-powered waving queen; a belly button brush; a silver-plated ice cream tub holder; a “hilarious” inflatable zimmer frame; a confection of plastic and electronics called Terry the Swearing Turtle; or – and somehow I find this significant – a Scratch Off World wall map.
They seem amusing on the first day of Christmas, daft on the second, embarrassing on the third. By the twelfth they’re in landfill. For thirty seconds of dubious entertainment, or a hedonic stimulus that lasts no longer than a nicotine hit, we commission the use of materials whose impacts will ramify for generations.
Researching her film The Story of Stuff, Annie Leonard discovered that of the materials flowing through the consumer economy, only 1% remain in use six months after sale(1). Even the goods we might have expected to hold onto are soon condemned to destruction through either planned obsolescence (breaking quickly) or perceived obsolesence (becoming unfashionable).
But many of the products we buy, especially for Christmas, cannot become obsolescent. The term implies a loss of utility, but they had no utility in the first place. An electronic drum-machine t-shirt; a Darth Vader talking piggy bank; an ear-shaped i-phone case; an individual beer can chiller; an electronic wine breather; a sonic screwdriver remote control; bacon toothpaste; a dancing dog: no one is expected to use them, or even look at them, after Christmas Day. They are designed to elicit thanks, perhaps a snigger or two, and then be thrown away.
The fatuity of the products is matched by the profundity of the impacts. Rare materials, complex electronics, the energy needed for manufacture and transport are extracted and refined and combined into compounds of utter pointlessness. When you take account of the fossil fuels whose use we commission in other countries, manufacturing and consumption are responsible for more than half of our carbon dioxide production(2). We are screwing the planet to make solar-powered bath thermometers and desktop crazy golfers.
People in eastern Congo are massacred to facilitate smart phone upgrades of ever diminishing marginal utility(3). Forests are felled to make “personalised heart-shaped wooden cheese board sets”. Rivers are poisoned to manufacture talking fish. This is pathological consumption: a world-consuming epidemic of collective madness, rendered so normal by advertising and the media that we scarcely notice what has happened to us.
In 2007, the journalist Adam Welz records, 13 rhinos were killed by poachers in South Africa. This year, so far, 585 have been shot(4). No one is entirely sure why. But one answer is that very rich people in Vietnam are now sprinkling ground rhino horn on their food or snorting it like cocaine to display their wealth. It’s grotesque, but it scarcely differs from what almost everyone in industrialised nations is doing: trashing the living world through pointless consumption.
This boom has not happened by accident. Our lives have been corralled and shaped in order to encourage it. World trade rules force countries to participate in the festival of junk. Governments cut taxes, deregulate business, manipulate interest rates to stimulate spending. But seldom do the engineers of these policies stop and ask “spending on what?”. When every conceivable want and need has been met (among those who have disposable money), growth depends on selling the utterly useless. The solemnity of the state, its might and majesty, are harnessed to the task of delivering Terry the Swearing Turtle to our doors.
Grown men and women devote their lives to manufacturing and marketing this rubbish, and dissing the idea of living without it. “I always knit my gifts”, says a woman in a television ad for an electronics outlet. “Well you shouldn’t,” replies the narrator(5). An advertisement for Google’s latest tablet shows a father and son camping in the woods. Their enjoyment depends on the Nexus 7’s special features(6). The best things in life are free, but we’ve found a way of selling them to you.
The growth of inequality that has accompanied the consumer boom ensures that the rising economic tide no longer lifts all boats. In the US in 2010 a remarkable 93% of the growth in incomes accrued to the top 1% of the population(7). The old excuse, that we must trash the planet to help the poor, simply does not wash. For a few decades of extra enrichment for those who already possess more money than they know how to spend, the prospects of everyone else who will live on this earth are diminished.
So effectively have governments, the media and advertisers associated consumption with prosperity and happiness that to say these things is to expose yourself to opprobrium and ridicule. Witness last week’s Moral Maze programme, in which most of the panel lined up to decry the idea of consuming less, and to associate it, somehow, with authoritarianism(8). When the world goes mad, those who resist are denounced as lunatics.
Bake them a cake, write them a poem, give them a kiss, tell them a joke, but for god’s sake stop trashing the planet to tell someone you care. All it shows is that you don’t.
The rich world is causing the famines it claims to be preventing, by George Monbiot, published in the Guardian 14th August 2012
I don’t blame Mo Farah, Pele and Haile Gebrselassie, who lined up, all hugs and smiles, outside Downing Street for a photocall at the prime minister’s hunger summit. Perhaps they were unaware of the way in which they were being used to promote his corporate and paternalistic approach to overseas aid. Perhaps they were also unaware of the crime against humanity over which he presides. Perhaps Cameron himself is unaware of it.
You should by now have heard about the famine developing in the Sahel region of West Africa. Poor harvests and high food prices threaten the lives of some 18 million people. The global price of food is likely to rise still further, as a result of low crop yields in the United States, caused by the worst drought in 50 years. World cereal prices, in response to this disaster, climbed 17% last month.
We have been cautious about attributing such events to climate change: perhaps too cautious. A new paper by James Hansen, head of NASA’s Goddard Institute for Space Studies, shows that there has been a sharp increase in the frequency of extremely hot summers. Between 1951 and 1980 these events affected between 0.1 and 0.2% of the world’s land surface each year. Now, on average, they affect 10%. Hansen explains that “the odds that natural variability created these extremes are minuscule, vanishingly small”. Both the droughts in the Sahel and the US crop failures are likely to be the result of climate change.
But this is not the only sense in which the rich world’s use of fuel is causing the poor to starve. In the United Kingdom, in the rest of the European Union and in the United States, governments have chosen to deploy a cure as bad as the disease. Despite overwhelming evidence of the harm their policy is causing, none of them will change course.
Biofuels are the means by which governments in the rich world avoid hard choices. Rather than raise fuel economy standards as far as technology allows, rather than promoting a shift from driving to public transport, walking and cycling, rather than insisting on better town planning to reduce the need to travel, they have chosen to exchange our wild overconsumption of petroleum for the wild overconsumption of fuel made from crops. No one has to drive less or make a better car: everything remains the same except the source of fuel. The result is a competition between the world’s richest and poorest consumers, a contest between overconsumption and survival. There was never any doubt about which side would win.
I’ve been banging on about this since 2004, and everything I warned of then has happened. The US and the European Union have both set targets and created generous financial incentives for the use of biofuels. The results have been a disaster for people and the planet.
Already, 40% of US corn (maize) production is used to feed cars. The proportion will rise this year as a result of the smaller harvest. Though the market for biodiesel is largely confined to the European Union, it has already captured seven per cent of the world’s output of vegetable oil. The European Commission admits that its target (10% of transport fuels by 2020) will raise world cereal prices by between 3 and 6%. Oxfam estimates that with every 1% increase in the price of food, another 16 million people go hungry.
By 2021, the OECD says, 14% of the world’s maize and other coarse grains, 16% of its vegetable oil and 34% of its sugarcane will be used to make people in the gas guzzling nations feel better about themselves. The demand for biofuel will be met, it reports, partly through an increase in production; partly through a “reduction in human consumption.” The poor will starve so that the rich can drive.
The rich world’s demand for biofuels is already causing a global land grab. ActionAid estimates that European companies have now seized five million hectares of farmland – an area the size of Denmark – in developing countries for industrial biofuel production. Small farmers, growing food for themselves and local markets, have been thrown off their land and destituted. Tropical forests, savannahs and grasslands have been cleared to plant what the industry still calls “green fuels”.
When the impacts of land clearance and the use of nitrogen fertilisers are taken into account, biofuels produce more greenhouse gases than fossil fuels do. The UK, which claims that half the biofuel sold here meets its sustainability criteria, solves this problem by excluding the greenhouse gas emissions caused by changes in land use. Its sustainability criteria are, as a result, worthless.
Even second generation biofuels, made from crop wastes or wood, are an environmental disaster, either extending the cultivated area or removing the straw and stovers which protect the soil from erosion and keep carbon and nutrients in the ground. The combination of first and second generation biofuels – encouraging farmers to plough up grasslands and to leave the soil bare – and hot summers could create the perfect conditions for a new dust bowl.
Our government knows all this. One of its own studies shows that if the European Union stopped producing biofuels, the amount of vegetable oils it exported to world markets would rise by 20% and the amount of wheat by 33%, reducing world prices.
Preparing for the prime minister’s hunger summit on Sunday, the international development department argued that, with a rising population, “the food production system will need to be radically overhauled, not just to produce more food but to produce it sustainably and fairly to ensure that the poorest people have the access to food that they need.” But another government department – transport – boasts on its website that, thanks to its policies, drivers in this country have now used 4.4 billion litres of biofuel. Of this 30% was produced from recycled cooking oil. The rest consists of 3 billion litres of refined energy snatched from the mouths of the people that David Cameron claims to be helping.
Some of those to whom the government is now extending its “nutrition interventions” may have been starved by its own policies. In this and other ways, David Cameron, with the unwitting support of various sporting heroes, is offering charity, not justice. And that is no basis for liberating the poor.
Even if greenhouse emissions stopped overnight the concentrations already in the atmosphere would still mean a global rise of between 0.5 and 1C. A shift of a single degree is barely perceptible to human skin, but it’s not human skin we’re talking about. It’s the planet; and an average increase of one degree across its entire surface means huge changes in climatic extremes.
Six thousand years ago, when the world was one degree warmer than it is now, the American agricultural heartland around Nebraska was desert.
The effect of one-degree warming, therefore, requires no great feat of imagination.

“The western United States once again could suffer perennial droughts, far worse than the 1930s. Deserts will reappear particularly in Nebraska, but also in eastern Montana, Wyoming and Arizona, northern Texas and Oklahoma. As dust and sandstorms turn day into night across thousands of miles of former prairie, farmsteads, roads and even entire towns will be engulfed by sand.”
What’s bad for America will be worse for poorer countries closer to the equator. It has beencalculated that a one-degree increase would eliminate fresh water from a third of the world’s land surface by 2100. Again we have seen what this means. There was an incident in the summer of 2005: One tributary fell so low that miles of exposed riverbank dried out into sand dunes, with winds whipping up thick sandstorms. As desperate villagers looked out onto baking mud instead of flowing water, the army was drafted in to ferry precious drinking water up the river – by helicopter, since most of the river was too low to be navigable by boat. The river in question was not some small, insignificant trickle in Sussex. It was the Amazon.
While tropical lands teeter on the brink, the Arctic already may have passed the point of no return. Warming near the pole is much faster than the global average, with the result that Arctic icecaps and glaciers have lost 400 cubic kilometres of ice in 40 years. Permafrost – ground that has lain frozen for thousands of years – is dissolving into mud and lakes, destabilising whole areas as the ground collapses beneath buildings, roads and pipelines. As polar bears and Inuits are being pushed off the top of the planet, previous predictions are starting to look optimistic. Earlier snowmelt means more summer heat goes into the air and ground rather than into melting snow, raising temperatures in a positive feedback effect. More dark shrubs and forest on formerly bleak tundra means still more heat is absorbed by vegetation.
Out at sea the pace is even faster. Whilst snow-covered ice reflects more than 80% of the sun’s heat, the darker ocean absorbs up to 95% of solar radiation. Once sea ice begins to melt, in other words, the process becomes self-reinforcing. More ocean surface is revealed, absorbing solar heat, raising temperatures and making it unlikelier that ice will re-form next winter. The disappearance of 720,000 square kilometres of supposedly permanent ice in a single year testifies to the rapidity of planetary change. If you have ever wondered what it will feel like when the Earth crosses a tipping point, savour the moment.
Mountains, too, are starting to come apart. In the Alps, most ground above 3,000 metres is stabilised by permafrost. In the summer of 2003, however, the melt zone climbed right up to 4,600 metres, higher than the summit of the Matterhorn and nearly as high as Mont Blanc. With the glue of millennia melting away, rocks showered down and 50 climbers died. As temperatures go on edging upwards, it won’t just be mountaineers who flee. Whole towns and villages will be at risk. Some towns, like Pontresina in eastern Switzerland, have already begun building bulwarks against landslides.
At the opposite end of the scale, low-lying atoll countries such as the Maldives will be preparing for extinction as sea levels rise, and mainland coasts – in particular the eastern US and Gulf of Mexico, the Caribbean and Pacific islands and the Bay of Bengal – will be hit by stronger and stronger hurricanes as the water warms. Hurricane Katrina, which in 2005 hit New Orleans with the combined impacts of earthquake and flood, was a nightmare precursor of what the future holds.
Most striking of all was seeing how people behaved once the veneer of civilisation had been torn away. Most victims were poor and black, left to fend for themselves as the police either joined in the looting or deserted the area. Four days into the crisis, survivors were packed into the city’s Superdome, living next to overflowing toilets and rotting bodies as gangs of young men with guns seized the only food and water available. Perhaps the most memorable scene was a single military helicopter landing for just a few minutes, its crew flinging food parcels and water bottles out onto the ground before hurriedly taking off again as if from a war zone. In scenes more like a Third World refugee camp than an American urban centre, young men fought for the water as pregnant women and the elderly looked on with nothing. Don’t blame them for behaving like this, I thought. It’s what happens when people are desperate.
Chance of avoiding one degree of global warming: zero.

More oil has been found than in Saudi Arabia, the military is stronger than ever before, yet the US is on the verge of collapse – morally, socially and economically. The gun and the dollar’s international primacy may keep it afloat, but the people are suffering.
In the largest state of California three cities have now filed for bankruptcy.
With the massive shift of wealth in the USA to the top 2% the bottom 50% now share only 2.5% of total wealth. Those at the bottom 25% (half of the bottom 50%) are basically destitute. More Americans need food-stamps now just to survive than just about any time in our history. Yet, no politician running for President mentions any of this. It is not a “plank” on any major (or minor) political parties agenda. None of the self proclaimed religious candidates mention poverty. It is a dirty big secret that we do not talk about in public. In fact, with nearly all attention being focused on cutting spending, only social spending not military spending, poverty is certainly going to increase even more.
In 2008, 17 million households, 14.6 percent of households (approximately one in seven), were food insecure, the highest number ever recorded in the United States. Four million households became food insecure in 2008, the largest increase ever recorded (p. iii, USDA 2008). (To get population figures from family size figures, multiply family size numbers by 2.58, the average family size.)
Researchers find 14.7 million children were poor in 2009, 2.5 million more than in 2000 hild poverty increased in 38 states from 2000 to 2009. As a result, 14.7 million children, 20 percent, were poor in 2009. That represents a 2.5 million increase from 2000, when 17 percent of the nation’s youth lived in low-income homes.
With the country in its worst economic crisis since the Great Depression, four million additional Americans found themselves in poverty in 2009, with the total reaching 44 million, or one in seven residents. Millions more were surviving only because of expanded unemployment insurance and other assistance.
Using an expanded definition of poverty, the U.S. Census Bureau said it determined that 15.7 percent of Americans — 47.8 million — live in poverty. Some 43 Million Use Food Stamps More than 14% of the population drew food stamps in November to purchase groceries as high unemployment and muted wage growth crimped budgets.
It is, perhaps, the greatest failure of collective leadership since the first world war. The Earth’s living systems are collapsing, and the leaders of some of the most powerful nations – the US, the UK, Germany, Russia – could not even be bothered to turn up and discuss it. Those who did attend the Earth summit last week solemnly agreed to keep stoking the destructive fires: sixteen times in their text they pledged to pursue “sustained growth”, the primary cause of the biosphere’s losses(1).
This is by George Monbiot of The Guardian.
The efforts of governments are concentrated not on defending the living Earth from destruction, but on defending the machine that is destroying it. Whenever consumer capitalism becomes snarled up by its own contradictions, governments scramble to mend the machine, to ensure – though it consumes the conditions that sustain our lives – that it runs faster than ever before.
The thought that it might be the wrong machine, pursuing the wrong task, cannot even be voiced in mainstream politics. The machine greatly enriches the economic elite, while insulating the political elite from the mass movements it might otherwise confront. We have our bread; now we are wandering, in spellbound reverie, among the circuses.
We have used our unprecedented freedoms, secured at such cost by our forebears, not to agitate for justice, for redistribution, for the defence of our common interests, but to pursue the dopamine hits triggered by the purchase of products we do not need. The world’s most inventive minds are deployed not to improve the lot of humankind but to devise ever more effective means of stimulation, to counteract the diminishing satisfactions of consumption. The mutual dependencies of consumer capitalism ensure that we all unwittingly conspire in the trashing of what may be the only living planet. The failure at Rio de Janeiro belongs to us all.
It marks, more or less, the end of the multilateral effort to protect the biosphere. The only successful global instrument – the Montreal Protocol on substances that deplete the ozone layer – was agreed and implemented years before the first Earth Summit in 1992(2). It was one of the last fruits of a different political era, in which intervention in the market for the sake of the greater good was not considered anathema, even by the Thatcher and Reagan governments. Everything of value discussed since then has led to weak, unenforceable agreements, or to no agreements at all.
This is not to suggest that the global system and its increasingly pointless annual meetings will disappear or even change. The governments which allowed the Earth Summit and all such meetings to fail evince no sense of responsibility for this outcome, and appear untroubled by the thought that if a system hasn’t worked for 20 years there’s something wrong with the system. They walk away, aware that there are no political penalties; that the media is as absorbed in consumerist trivia as the rest of us; that, when future generations have to struggle with the mess they have left behind, their contribution will have been forgotton. (And then they lecture the rest of us on responsibility).
Nor is it to suggest that multilateralism should be abandoned. Agreements on biodiversity, the oceans and the trade in endangered species may achieve some marginal mitigation of the full-spectrum assault on the biosphere that the consumption machine has unleashed. But that’s about it.
The action – if action there is – will mostly be elsewhere. Those governments which retain an interest in planet Earth will have to work alone, or in agreement with likeminded nations. There will be no means of restraining free riders, no means of persuading voters that their actions will be matched by those of other countries.
That we have missed the chance of preventing two degrees of global warming now seems obvious. That most of the other planetary boundaries will be crossed, equally so. So what do we do now?
Some people will respond by giving up, or at least withdrawing from political action. Why, they will ask, should we bother, if the inevitable destination is the loss of so much of what we hold dear: the forests, the brooks, the wetlands, the coral reefs, the sea ice, the glaciers, the birdsong and the night chorus, the soft and steady climate which has treated us kindly for so long? It seems to me that there are at least three reasons.
The first is to draw out the losses over as long a period as possible, in order to allow our children and grandchildren to experience something of the wonder and delight in the natural world and of the peaceful, unharried lives with which we have been blessed. Is that not a worthy aim, even if there were no other?
The second is to preserve what we can in the hope that conditions might change. I do not believe that the planet-eating machine, maintained by an army of mechanics, oiled by constant injections of public money, will collapse before the living systems on which it feeds. But I might be wrong. Would it not be a terrible waste to allow the tiger, the rhinoceros, the bluefin tuna, the queen’s executioner beetle and the scabious cuckoo bee, the hotlips fungus and the fountain anenome(3) to disappear without a fight if this period of intense exploitation turns out to be a brief one?
The third is that, while we may possess no influence over decisions made elsewhere, there is plenty that can be done within our own borders. Rewilding – the mass restoration of ecosystems – offers the best hope we have of creating refuges for the natural world, which is why I’ve decided to spend much of the next few years promoting it here and abroad.
Giving up on global agreements or, more accurately, on the prospect that they will substantially alter our relationship with the natural world, is almost a relief. It means walking away from decades of anger and frustration. It means turning away from a place in which we have no agency to one in which we have, at least, a chance of being heard. But it also invokes a great sadness, as it means giving up on so much else.
Was it too much to have asked of the world’s governments, which performed such miracles in developing stealth bombers and drone warfare, global markets and trillion dollar bail-outs, that they might spend a tenth of the energy and resources they devoted to these projects on defending our living planet? It seems, sadly, that it was.
Everything you think you know about economics … is wrong. Dead wrong. And until economics acknowledge this, the discipline is on a self-destruct path.
Why? The science of economics is not science. Yes, it looks scientific with all the fancy math algorithms and computer models that economists use, but all that’s just window dressing to make the economist look scientific and rational.
They’re not. Their conclusions are pre-ordained, fabricated, based on their biases, personal ideologies and whatever their employer wants to prove to manipulate consumers, voters or investors to buy what they’re selling.
Because all economics is based on the absurd Myth of Perpetual Growth. Yes, all theories and business plans based on growth are mythological.
Economists are master illusionists who rely on a set of fictions, fantasies and forecasts that emanate from a core magical mantra of Perpetual Growth that goes untested year after year.
And yet it’s used to manipulate the public into a set of policies and decisions that are leading the American and the world economy down a path of unsustainable globalization and GDP growth assumptions that will self-destruct the planet.

Today is a pivotal point in human history. We are now living in the Anthropocene: humans are the main driver of planetary change. We’re pushing global temperatures, land and water use beyond anything our species has experienced before. We’re polluting the biosphere, acidifying the oceans, and reducing biodiversity. At the same time, our global population will grow from seven billion to nine billion by 2050, and all will need food, water and clean air.
As if to illustrate the point further, last month Arctic monitors showed the concentration of carbon dioxide in the atmosphere has passed 400 parts per million (before the Industrial Age, carbon dioxide levels were 275 ppm). New data shows the rate of climate change could be even faster than thought.
Perhaps most worryingly of all, 22 scientists warned last week we are approaching a planetary tipping point, beyond which environmental changes will be rapid and unpredictable. Basing their alarming conclusion on studies of ecological markers from species extinction rates (currently 1,000 times the usual rate, and comparable to those experienced during the demise of the dinosaurs) to changes in land use (more than 40% of land is dominated by humans and we affect a further 40%), these scientists fear we will enter a new, unknown state, and one which threatens us all.
As you might have noticed, the stock market is falling like a stone. As of 9 AM PST, the Dow Jones has dropped 172 points while all the other indices are down sharply. German 2-year debt (bund) has dipped below 0% this morning at auction, signalling an acceleration in the bank run taking place in southern Europe. Depositors in Spain, Greece, Italy, Portugal, etc would rather take a loss on their investment, then risk not their money back at all. The European Central Bank (ECB) does not guarantee deposits, so people are withdrawing their money en masse and getting out of Dodge pronto. What we’re seeing is a real-time panic.
The ostensible trigger for the panic is known, but you won’t read about it in the financial media where the news is dumbed down to the point of incoherence. What’s really going on is that the German central bank (The Bundesbank) has indicated that it’s ready to pull the plug on Greece which means that future bailouts will probably not be forthcoming. That’s bad. It means that Greece will run out of money some time in June; their banking system will implode, and the “birthplace of democracy” will be reduced to 3rd world status overnight.

Almost 5% of Africa‘s agricultural land has been bought or leased by investors since 2000, according to an international coalition of researchers and NGOs that has released the world’s largest public database of international land deals.
The database, launched on Thursday, lifts the lid on a decade of secretive deals struck by governments, investors and speculators seeking large tracts of fertile land in developing countries around the world.
The past five years have seen a flood of reports of investors snapping up land at rock-bottom prices in some of the world’s poorest countries. But, despite growing concern about the local impacts of so-called “land grabs”, the lack of reliable data has made it difficult to pin down the real extent and nature of the global rush for land.
