Is this challenge for the political process achievable?

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.

Turbulent Times, the key message

Core message from my YouTube talk  http://www.youtube.com/watch?v=UFhNyWHv0qQ&feature=youtu.be

Let go – or be dragged – but NEVER GIVE UP

I am letting go of the notion that homo sapiens will inhabit this planet beyond 2030.

I am letting go of the notion that within a few short years, there will still be any comfortable habitat for humans anywhere.

I am letting go of the notion that we will retain even one percent of the species currently in Earth beyond 2050.

But I am not letting go of the notion of resistance, for that is what makes me human.

THEREFORE

Feel GOOD to be alive – always, every day

Don’t consume ANYTHING you don’t need

We are the most creative creatures on the planet

LETS USE IT

 

The gift of death – Monbiot

 


 

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.

Tipping Point Near

No alternative to atmospheric CO2 draw-down

The scale and rate of modern climate change have been underestimated. The release to date of a total of over 500 billion ton (GtC) of carbon through emissions, land clearing and fires, has raised CO2 levels to 397-400 ppm and near 470 ppm CO2-e [a value including methane] at a rate of ~2 ppm CO2 per year [1] (Figures 1 and 2). These developments are shifting the Earth’s climate toward Pliocene-like (5.2 – 2.6 million years-ago [Ma]; +2-3oC) conditions and possibly mid-Miocene-like (~16 Ma; +4oC) conditions [2], within a couple of centuriesa geological blink of an eye.

The current CO2 level generates amplifying feedbacks from the ice/water transformation and albedo loss, methane release from permafrost, methane clathrates and bogs, from droughts and loss of vegetation cover, from fires and from reduced CO2 sequestration by warming water. With CO2 atmospheric residence times in the order of thousands to tens of thousands years [3], protracted reduction in emissions, either flowing from human decision or due to reduced economic activity in an environmentally stressed world, may no longer be sufficient to arrest the feedbacks.

Four of the large mass extinction events in the history of Earth (end-Devonian, Permian-Triassic, end-Triassic, K-T boundary) have been associated with rapid perturbations of the carbon, oxygen and sulphur cycles, on which the biosphere depends, at rates to which species could not adapt [4].

Since the 18th century, and in particular since about 1975, the Earth system has been shifting away from Holocene (10,000 years to the present) conditions, which allowed agriculture, previously not possible due to instabilities in the climate and extreme weather events. The shift is most clearly manifested by the loss of polar ice [5] (Figure 3). Sea level rises have been accelerating, with a total of more than 20 cm since 1880 and about 6 cm since 1990 [6] (Figure 4).

For temperature rise of 2.3oC, to which the climate is committed if sulphur aerosol emission discontinues (see Figure 1), sea levels would reach Pliocene like levels of 25+/-12 meters, with lag effects due to ice sheet hysteresis.

With global CO2 levels at 400 ppm, the upper stability limit of the Antarctic ice sheet, current rate of CO2 emissions from fossil fuel combustion, cement production, land clearing and fires of ~9.7 GtC in 2010 [7] , global civilization is at a tipping point, facing the following alternatives: 

1. With carbon reserves sufficient to raise atmospheric CO2 levels to above 1000 ppm (Figure 5), continuing business-as-usual emissions can only result in advanced melting of the polar ice sheets, a corresponding rise of sea levels on the scale of meters to tens of meters and continental temperatures rendering agriculture unlikely.

2. With atmospheric CO2 at ~400 ppm, abrupt decrease in carbon emissions may no longer be sufficient to prevent current feedbacks (melting of ice, methane release from permafrost, fires). Attempts to stabilize the climate would require global efforts at CO2 draw-down, using a range of methods including global reforestation, extensive biochar application, chemical CO2 sequestration (using sodium hydroxide, serpentine and new
innovations) and burial of CO2 [8]

As indicated in Table 1, the use of short-term solar radiation shields such as sulphur aerosols cannot be regarded as more than a band aid, with severe deleterious consequences in terms of ocean acidification and retardation of the monsoon and of precipitation over large parts of the Earth. Retardation of solar radiation through space sunshades is of limited residence time and would not prevent further acidification from ongoing carbon emission.

Dissemination of ocean iron filings aimed at increasing fertilization by plankton and algal blooms, or temperature exchange through vertical ocean pipe systems, are unlikely to be effective in transporting CO2 to relatively safe water depths.

By contrast to these methods, CO2 sequestration through fast track reforestation, soil carbon, biochar and possible chemical methods such as “sodium trees” and serpentine (combining Ca and Mg with CO2) (Figure 6) may be effective, provided these are applied on a global scale, requiring budgets on a scale of military spending (>$20 trillion since WWII).

Urgent efforts at innovation of new CO2 draw-down methods are essential. It is likely that a species which decoded the basic laws of nature, split the atom, placed a man on the moon and ventured into outer space should also be able to develop the methodology for fast sequestration of atmospheric CO2. The alternative, in terms of global heating, sea level rise, extreme weather events, and the destruction of the world’s food sources is unthinkable.

Good planets are hard to come by.
