William deBuys, The Parching of the West

Once again, a powerful essay from the TomDispatch blog.

Quick introduction.  Tom Engelhardt, of TomDispatch, has given me a blanket permission to reproduce his essays.  As always, I am indebted to his generosity.  This particular essay is extremely timely coming after my Post yesterday about extreme weather.

Tomgram: William deBuys, The Parching of the West

Posted by William deBuys at 6:02pm, December 4, 2011.

The good news? While 2010 tied for the warmest year on record, 2011 — according to the U.N.’s World Meteorological Organization (WMO) — is likely to come in 10th once November and December temperatures are tallied. In part, this is evidently due to an especially strong La Niña cooling event in the Pacific.  On the other hand, with 2011 in the top ten despite La Niña, 13 of the warmest years since such record-keeping began have occurred in the last 15 years.  Think of that as an uncomfortably hot cluster.

And other climate news is no better.  A recent study indicates that Arctic ice is now melting at rates unprecedented in the last 1,450 years (as far back, that is, as reasonably accurate reconstructions of such an environment can be modeled).  As the Arctic warms and temperatures rise in surrounding northern lands — someday, Finland may have to construct artificial ski trails and ice rinks for its future winter tourists — a report on yet another study is bringing more lousy news.  Appearing in the prestigious science journal Nature, it indicates that the melting permafrost of the tundra may soon begin releasing global-warming gases into the atmosphere in massive quantities.  We’re talking the equivalent of 300 billion metric tons of carbon over the next nine decades.

Recently, Fatih Birol, the chief economist for the International Energy Agency, suggested that, by century’s end, the planet’s temperature could rise by a staggering 6º Celsius (almost 11º Fahrenheit).  International climate-change negotiators had been trying to keep that rise to a “mere” 2º C.  “Everybody, even the schoolchildren, knows this is a catastrophe for all of us,” was the way Birol summed the situation up.  If only it were so, but here in the U.S., none of the above news was even considered front-page worthy.  Nor was the news that, in 2010, humans had pumped more carbon dioxide into the atmosphere than at any time since the industrial revolution began: 564 million more tons than in 2009 to be exact.  We’re living today with just less than a degree of those six degrees to come, and the results in extreme weather this year should have made us all stop and think.

If you want to focus in on damage here in the U.S., consider Rick Perry’s Texas, where, according to scientists, “daily temperatures averaged 86.7° in June through August — a staggering 5.4°F above normal.”  According to the WMO, that’s the highest such average “ever recorded for any American state.”  And still global politicians yammer on and do little; still, the U.S. shuffles its political feet, while Canada’s government has announced that it will make no new commitments and may even be preparing to withdraw from the Kyoto protocol, and countries with booming developing economies like China, India, and Brazil hedge their bets when it comes to action.

In the meantime, nature doesn’t care whether or not we do anything.  It’s on its own schedule.  And when it comes to the American Southwest, that schedule looks daunting indeed as William deBuys makes clear.  His new book, A Great Aridness: Climate Change and the Future of the American Southwest, is the definitive work on the subject of water and the West (and, as with all of his work, a pleasure to read). So get yourself a glass of water while you still can and settle in for a dose of the Age of Thirst.

The Age of Thirst in the American West
Coming to a Theater Near You: The Greatest Water Crisis in the History of Civilization 
By William deBuys

Consider it a taste of the future: the fire, smoke, drought, dust, and heat that have made life unpleasant, if not dangerous, from Louisiana to Los Angeles. New records tell the tale: biggest wildfire ever recorded in Arizona (538,049 acres),biggest fire ever in New Mexico (156,600 acres), all-time worst fire year in Texas history (3,697,000 acres).

The fires were a function of drought.  As of summer’s end, 2011 was the driest year in 117 years of record keeping for New Mexico, Texas, and Louisiana, and the second driest for Oklahoma. Those fires also resulted from record heat.  It was the hottest summer ever recorded for New Mexico, Texas, Oklahoma, and Louisiana, as well as the hottest August ever for those states, plus Arizona and Colorado.

Virtually every city in the region experienced unprecedented temperatures, with Phoenix, as usual, leading the march toward unlivability. This past summer, the so-called Valley of the Sun set a new record of 33 days when the mercury reached a shoe-melting 110º F or higher. (The previous record of 32 days was set in 2007.)

And here’s the bad news in a nutshell: if you live in the Southwest or just about anywhere in the American West, you or your children and grandchildren could soon enough be facing the Age of Thirst, which may also prove to be the greatest water crisis in the history of civilization.  No kidding.

If that gets you down, here’s a little cheer-up note: the end is not yet nigh.

In fact, this year the weather elsewhere rode to the rescue, and the news for the Southwest was good where it really mattered.  Since January, the biggest reservoir in the United States, Lake Mead, backed up by the Hoover Dam and just 30 miles southwest of Las Vegas, has risen almost 40 feet. That lake is crucial when it comes to watering lawns or taking showers from Arizona to California.  And the near 40-foot surge of extra water offered a significant upward nudge to the Southwest’s water reserves.

The Colorado River, which the reservoir impounds, supplies all or part of the water on which nearly 30 million people depend, most of them living downstream of Lake Mead in Los Angeles, San Diego, Phoenix, Tucson, Tijuana, and scores of smaller communities in the United States and Mexico.

Back in 1999, the lake was full. Patricia Mulroy, who heads the water utility serving Las Vegas, rues the optimism of those bygone days.  “We had a fifty-year, reliable water supply,” she says. “By 2002, we had no water supply. We were out. We were done. I swore to myself we’d never do that again.”

In 2000, the lake began to fall — like a boulder off a cliff, bouncing a couple of times on the way down. Its water level dropped a staggering 130 feet, stopping less than seven feet above the stage that would have triggered reductions in downstream deliveries. Then — and here’s the good news, just in case you were wondering — last winter, it snowed prodigiously up north in Colorado, Utah, and Wyoming.

The spring and summer run-off from those snowpacks brought enormous relief. It renewed what we in the Southwest like to call the Hydro-Illogic cycle: when drought comes, everybody wrings their hands and promises to institute needed reform, if only it would rain a little. Then the drought breaks or eases and we all return to business as usual, until the cycle comes around to drought again.

So don’t be fooled.  One day, perhaps soon, Lake Mead will renew its downward plunge.  That’s a certainty, the experts tell us.  And here’s the thing: the next time, a sudden rescue by heavy snows in the northern Rockies might not come. If the snowpacks of the future are merely ordinary, let alone puny, then you’ll know that we really are entering a new age.

And climate change will be a major reason, but we’ll have done a good job of aiding and abetting it. The states of the so-called Lower Basin of the Colorado River — California, Arizona, and Nevada — have been living beyond their water means for years. Any departure from recent decades of hydrological abundance, even a return to long-term average flows in the Colorado River, would produce a painful reckoning for the Lower Basin states.  And even worse is surely on the way.

Just think of the coming Age of Thirst in the American Southwest and West as a three-act tragedy of Shakespearean dimensions.

The Age of Thirst: Act I

The curtain in this play would surely rise on the Colorado River Compact of 1922, which divided the river’s water equally between the Upper and Lower Basins, allocating to each annually 7.5 million acre-feet, also known by its acronym “maf.” (An acre-foot suffices to support three or four families for a year.) Unfortunately, the architects of the compact, drawing on data from an anomalously wet historical period, assumed the river’s average annual flow to be about 17 maf per year.  Based on reconstructions that now stretch back more than 1,000 years, the river’s long-term average is closer to 14.7 maf.  Factor in evaporation from reservoirs (1.5 maf per year) and our treaty obligation to Mexico (another 1.5 maf), and the math doesn’t favor a water-guzzling society.

Nonetheless, the states of the Lower Basin have been taking their allotment as if nothing were wrong and consequently overdrafting their account by up to 1.3 maf annually.  At this rate, even under unrealistically favorable scenarios, the Lower Basin will eventually drain Lake Mead and cutbacks will begin, possibly as soon as in the next few years.  And then things will get dicier because California, the water behemoth of the West, won’t have to absorb any of those cutbacks.

Here’s one of the screwiest quirks in western water law: to win Congressional approval for the building of a monumental aqueduct, the Central Arizona Project (CAP), which would bring Colorado River water to Phoenix and Tucson, Arizona agreed to subordinate its Colorado River water rights to California’s.  In that way, the $4 billion, 336-mile-long CAP was born, and for it Arizona paid a heavy price. The state obliged itself to absorb not just its own losses in a cutback situation, but California’s as well.

Worst case scenario: the CAP aqueduct, now a lifeline for millions, could become as dry as the desert it runs through, while California continues to bathe. Imagine Phoenix curling and cracking around the edges, while lawn sprinklers hiss in Malibu. The contrast will upset a lot of Arizonans.

Worse yet, the prospective schedule of cutbacks now in place for the coming bad times is too puny to save Lake Mead.

The Age of Thirst: Act II

While that Arizona-California relationship guarantees full employment for battalions of water lawyers, a far bigger problem looms: climate change. Models for the Southwest have been predicting a 4ºC (7.2ºF) increase in mean temperature by century’s end, and events seem to be outpacing the predictions.

We have already experienced close to 1º C of that increase, which accounts, at least in part, for last summer’s colossal fires and record-setting temperatures — and it’s now clear that we’re just getting started.

The simple rule of thumb for climate change is that wet places will get wetter and dry places drier. One reason the dry places will dry is that higher temperatures mean more evaporation. In other words, there will be ever less water in the rivers that keep the region’s cities (and much else) alive. Modeling already suggests that by mid-century surface stream-flow will decline by 10% to 30%.

Independent studies at the Scripps Oceanographic Institute in California and the University of Colorado evaluated the viability of Lake Mead and eventually arrived at similar conclusions: after about 2026, the risk of “failure” at Lake Mead, according to a member of the Colorado group, “just skyrockets.” Failure in this context would mean water levels lower than the dam’s lowest intake, no water heading downstream, and the lake becoming a “dead pool.”

If — perhaps “when” is the more appropriate word — that happens, California’s Colorado River Aqueduct, which supplies water to Los Angeles, San Diego, and the All-American Canal, which sustains the Imperial and Coachella Valleys, will go just as dry as the Central Arizona Project aqueduct. Meanwhile, if climate change is affecting the Colorado River’s watershed that harshly, it will undoubtedly also be hitting the Sierra Nevada mountain range.

The aptly named Lester Snow, a recent director of California’s Department of Water Resources, understood this. His future water planning assumed a 40% decline in runoff from the Sierras, which feeds the California Aqueduct. None of his contemplated scenarios were happy ones. The Colorado River Aqueduct and the California Aqueduct make the urban conglomerations of southern California possible. If both fail at once, the result will be, as promised, the greatest water crisis in the history of civilization.

Only Patricia Mulroy has an endgame strategy for the demise of Lake Mead. The Southern Nevada Water Authority is, even now, tunneling under the lake to install the equivalent of a bathtub drain at close to its lowest point. At a cost of more than $800 million, it will drain the dregs of Lake Mead for Las Vegas.

Admittedly, water quality will be a problem, as the dead pool will concentrate pollutants. The good news, according to the standard joke among those who chronicle Sin City’s improbable history, is that the hard-partying residents and over-stimulated tourists who sip from Lake Mead’s last waters will no longer need to purchase anti-depressants. They’ll get all the Zoloft and Xanax they need from their tap water.

And only now do we arrive at the third act of this expanding tragedy.

The Age of Thirst: Act III

Those who believe in American exceptionalism hold that the historical patterns shaping the fate of other empires and nations don’t apply to the United States. Be that as it may, we are certainly on track to test whether the U.S. is similarly inoculated against the patterns of environmental history.

Because tree rings record growing conditions year by year, the people who study them have been able to reconstruct climate over very long spans of time. One of their biggest discoveries is that droughts more severe and far longer than anything known in recent centuries have occurred repeatedly in the American Southwest. The droughts of the Dust Bowl in the 1930s, of the 1950s, and of the period from 1998 to 2004 are remembered in the region, yet none lasted a full decade.

By contrast, the drought that brought the civilization of the ancestral Puebloans, or Anasazi, centered at Chaco Canyon, to its knees in the twelfth century, by contrast,lasted more than 30 years. The one that finished off Mesa Verdean culture in the thirteenth century was similarly a “megadrought.”

Jonathan Overpeck, a climate scientist at the University of Arizona who played a major role in the Nobel-Prize-winning work of the Intergovernmental Panel on Climate Change, tells me that the prospect of 130° F days in Phoenix worries him far less than the prospect of decades of acute dryness. “If anything is scary, the scariest is that we could trip across a transition into a megadrought.” He adds, “You can probably bet your house that, unless we do something about these greenhouse gas emissions, the megadroughts of the future are going to be a lot hotter than the ones of the past.”

Other scientists believe that the Southwest is already making the transition to a“new climatology,” a new normal that will at least bring to mind the aridity of theDust Bowl years. Richard Seager of Columbia University, for instance, suggests that “the cycle of natural dry periods and wet periods will continue, but… around a mean that gets drier. So the depths — the dry parts of the naturally occurring droughts — will be drier than we’re used to, and the wet parts won’t be as wet.”

Drought affects people differently from other disasters. After something terrible happens — tornados, earthquakes, hurricanes — people regularly come together in memorable ways, rising above the things that divide them. In a drought, however, what is terrible is that nothing happens. By the time you know you’re in one, you’ve already had an extended opportunity to meditate on the shortcomings of your neighbors. You wait for what does not arrive. You thirst. You never experience the rush of compassion that helps you behave well. Drought brings out the worst in us.

After the Chacoan drought, corn-farming ancestral Puebloans still remained in the Four Corners area of the Southwest. They hung on, even if at lower population densities. After the Mesa Verdean drought, everybody left.

By the number of smashed crania and other broken bones in the ruins of the region’s beautiful stone villages, archaeologists judge that the aridifying world of the Mesa Verdeans was fatally afflicted by violence. Warfare and societal breakdown, evidently driven by the changing climate, helped end that culture.

So it matters what we do. Within the limits imposed by the environment, the history we make is contingent, not fated. But we are not exactly off to a good start in dealing with the challenges ahead. The problem of water consumption in the Southwest is remarkably similar to the problem of greenhouse gas pollution. First, people haggle to exhaustion over the need to take action; then, they haggle over inadequate and largely symbolic reductions. For a host of well-considered, eminently understandable, and ultimately erroneous reasons, inaction becomes the main achievement. For this drama, think Hamlet. Or if the lobbyists who argue for business as usual out west and in Congress spring to mind first, think Iago.

We know at least one big thing about how this particular tragedy will turn out: the so-called civilization of the Southwest will not survive the present century, not at its present scale anyway. The question yet to be answered is how much it will have to shrink, and at what cost. Stay tuned. It will be one of the greatest, if grimmest, shows on Earth.

Too late to be a pessimist

A life-changing film

Last Friday I published a Post under the title of The power of truth.  Just 5 minutes long, the YouTube video was powerful, starkly so.  I wrote at the end of that article, “The principal source for the footage was Yann Arthus-Bertrand’s incredible film HOME.”

Jean and I watched Yann Arthus-Bertrand’s film last Friday night and to say that we were moved would be pitiful compared to the emotional impact it really had.  Take a look at the film trailer; it’s a little over 3 1/2 minutes long.  (But please don’t use that as a substitute for watching the full film, see below!)

Home is a 2009 documentary by Yann Arthus-Bertrand. The film is entirely composed of aerial shots of various places around Earth. It shows the diversity of life on Earth and how humanity is threatening the ecological balance of the planet. The movie was released simultaneously on June 5th in cinemas all over the world, on DVD and on YouTube. Released on the same date in 50 countries is a world record for any film release in history. The film is 100% free, and no profits will be made from its release or future showings.

I wasn’t going to add anything other than a brief introduction to the main film.  However, an article in The Economist The World in 2012 caught my eye and seemed especially relevant to promoting the message carried by the film. Sheryl Sandberg, chief operating officer of Facebook, wrote about the power of social media and how it would be even more evident in 2012.  This is the paragraph that caught my eye,

Expressing our authentic identity will become even more pervasive in the coming year. Profiles will no longer be outlines, but detailed self-portraits of who we really are, including the books we read, the music we listen to, the distances we run, the places we travel, the causes we support, the videos of cats we laugh at, our likes and our links. And, yes, this shift to authenticity will take getting used to and will elicit cries about lost privacy. But people will increasingly recognise the benefits of such expression. Because the strength of social media is that it empowers individuals to amplify and broadcast their voices. The truer that voice, the louder it will sound and the farther it will reach.

That last sentence jumped out at me, “The truer that voice, the louder it will sound and the farther it will reach.” Mull on that as you watch the film and, please, please, please if you support the need to return to a harmonious relationship with the planet spread the word as far and wide as you can.

Please promise yourself to sit down quietly and watch it uninterrupted.  And if you feel so minded to add comments to this Post please do – would be delighted to have your feedback.

HOME

We are living in exceptional times. Scientists tell us that we have 10 years to change the way we live, avert the depletion of natural resources and the catastrophic evolution of the Earth’s climate.

The stakes are high for us and our children. Everyone should take part in the effort, and HOME has been conceived to take a message of mobilization out to every human being.

For this purpose, HOME needs to be free. A patron, the PPR Group, made this possible. EuropaCorp, the distributor, also pledged not to make any profit because Home is a non-profit film.

HOME has been made for you : share it! And act for the planet.

A small step

Fabulous news from The President’s Office re the Keystone XL pipeline.

On the 27th October, I introduced an article about the pipeline, thus,

“Have the courage to say no. Have the courage to face the truth.  Do the right thing because it is right.  These are the magic keys to living your life with integrity.”

The above is attributed to W. Clement Stone, a businessman, philanthropist and author who died in 2002, aged 100.  It seemed an appropriate quotation with which to introduce a recent article by Bill McKibben, on the Grist blog, about the proposed Keystone XL pipeline.

A short time ago (Thursday) I received the following from Bill McKibben, 350.org.

Dear Friends,

Um, we won. You won.

Not completely. The President didn’t outright reject the Keystone XL pipeline permit. My particular fantasy — that he would invite the 1253 people arrested on his doorstep in August inside the gates for a victory picnic by the vegetable garden — didn’t materialize.

But a few minutes ago the President sent the pipeline back to the State Department for a thorough re-review, which most analysts are saying will effectively kill the project. The president explicitly noted climate change, along with the pipeline route, as one of the factors that a new review would need to assess. There’s no way, with an honest review, that a pipeline that helps speed the tapping of the world’s second-largest pool of carbon can pass environmental muster.

And he has made clear that the environmental assessment won’t be carried out by cronies of the pipeline company — that it will be an expert and independent assessment. We will watch that process like hawks, making sure that it doesn’t succumb to more cronyism. Perhaps this effort will go some tiny way towards cleaning up the Washington culture of corporate dominance that came so dramatically to light here in emails and lobbyist disclosure forms.

It’s important to understand how unlikely this victory is. Six months ago, almost no one outside the pipeline route even knew about Keystone XL. One month ago, a secret poll of “energy insiders” by the National Journal found that “virtually all” expected easy approval of the pipeline by year’s end. As late as last week the CBC reported that Transcanada was moving huge quantities of pipe across the border and seizing land by eminent domain, certain that its permit would be granted. A done deal has come spectacularly undone.

Our movement spoke loudly about climate change and the President responded. There have been few even partial victories about global warming in recent years so that makes this an important day. We need to let the president and oil companies know that we’re ready to take action should they try to push this pipeline through in a couple of years. There’s a pledge to take bold action against the pipeline up on our site, and I’ll be keeping your names an emails safely stored away so that you’ll be the first to know about anything we need to do down the road.

Please sign the pledge here.

The President deserves thanks for making this call — it’s not easy in the face of the fossil fuel industry and its endless reserves of cash. The deepest thanks, however, go to you: to indigenous peoples who began the fight, to the folks in Nebraska who rallied so fiercely, to the scientists who explained the stakes, to the environmental groups who joined with passionate common purpose, to the campuses that lit up with activity, to the faith leaders that raised a moral cry, to the labor leaders who recognized where our economic future lies, to the Occupy movement that helped galvanize revulsion at insider dealing, and most of all to the people in every state and province who built the movement that made this decision inevitable.

Our fight, of course, is barely begun. Some in our movement will say that this decision is just politics as usual: that the President wants us off the streets — and off his front lawn — until after the election, at which point the administration can approve the pipeline, alienating its supporters without electoral consequence. The president should know that If this pipeline proposal somehow reemerges from the review process we will use every tool at our disposal to keep it from ever being built; if there’s a lesson of the last few months, both in our work and in the Occupy encampments around the world, it’s that sometimes we have to put our bodies on the line.

In the meantime, since federal action will be in abeyance for a long stretch, we need to figure out how best to support our Canadian brothers and sisters, who are effectively battling against proposed pipelines west from the tar sands to the Pacific. And we need to broaden our work to take on all the forms of ‘extreme energy’ now coming to the fore: mountaintop removal coal mining, deepsea oil drilling, fracking for gas and oil. We’ll keep sending you updates; you keep letting us know what we need to do next.

Last week, scientists announced that the planet had poured a record amount of CO2 into the atmosphere last year; that’s a sign of how desperate our battle is. But we take courage from today’s White House announcement; it gives us some clues about how to fight going forward.

And I simply can’t say thank you enough. I know, because of my own weariness, how hard so many of you have worked. It was good work, done in the right spirit, and it has secured an unlikely victory. You are the cause of that victory; you upended enormous odds.

I’m going to bed tired tonight. But I’ll get up in the morning ready for the next battle, more confident because I know you’re part of this fight too.

Onwards,

Bill McKibben for the 350.org Team

P.S. Victories need to be shared. Let’s make this one fly all over the web: share it on Twitter here and share it on Facebook here.

 

Voices from the Beeline Café

The second guest post from John H.

John’s first guest contribution, Clarity of Thought, was published on the 20th September and attracted a collection of very thoughtful comments.  To give you a sense of that first contribution, it started thus,

The Passion of Enlightenment

Enlightenment includes deep grief and a passion to leave life a bit better than we found it. Enlightenment has little practical value in a growing and constantly consuming cultural demographic. Consumers tend to spiritually disconnect when faced by a need for change or when morality becomes inconvenient.

To set the scene for these musings from John, Highway 87 that runs South-North through Payson, where John lives, is called the Beeline Highway and there is, indeed, a Beeline Cafe in town.

Over to John now.

The view from the window.

Perhaps ancient man is still alive and well in all of us.

Two delightful events have provided the fuel for today’s post which, I warn you, is much more the personal mental ramble than the usual daily post on Learning from Dogs.  So, health warning, continue reading at your own risk, or be safe and switch off now!

Before getting in to my perambulations, just a word of thanks to you for your support.  Last month, there were 31,291 viewers of Learning from Dogs and 71 of you have chosen to subscribe.  I am humbled by your interest.  Don’t ever hesitate to give me feedback or, if you prefer, comment to a specific post.

OK, to the theme of today.

On Wednesday I had an enjoyable lunch with a friend from here in Payson, Dennis L.  Sitting in the Crosswinds restaurant at Payson airport is one of the most beautiful eating spots in terms of the view from the window.  So it’s a very conducive place to relax and try put the world to rights!  Conversation ranged across a variety of topics but frequently touched on the lunacy of so many things to do with man, especially when it comes to the government of peoples.

Dennis and I also acknowledged that entering politics with a set of passionate ideals, as we were sure many persons did, would quickly run up against the skein of vested interests that must permeate governments from top to bottom.

Yes Minister was a satirical comedy written by Antony Jay and Jonathan Lynn that ran for many years.  It was extraordinarily funny, here’s a 3-minute clip,

That programme underlined, far better than anything else, how governments most probably work in reality.

Dennis and I were clear, as so many millions of other global citizens must be, that the complexity of commerce, politics, national interests, global finance, and more, had created ‘systems’ of decision making that were utterly disconnected with the needs of mankind having a long and stable future on the only finite home around, Planet Earth.

Then today (Thursday), Jean and I attended our regular weekly gardening course at the local college in Payson.  Today’s subject was Arizona’s Climate and the tutor, Mike C., was a professional climatologist and meteorologist.  It was fascinating, indeed, totally absorbing.  Mike’s graphs and slides about the climate, some showing data for the last 1,000 years, underlined the incredible complexity and interconnectedness of the processes that made up the global climate system.

Once again that use of the word ‘complexity’.  He confirmed that there was no scientific doubt that the world was warming as a result of changes to the Earth’s atmosphere, science certain most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and burning fossil fuels.

Mike closed the session with an interesting reflection.  He reminded the audience that mankind is still essentially wired, in evolutionary terms, to know how to react to an attacking tiger or similar wild beast, as in the fight or flee response, than know how to deal with such complex, despite intellectually obvious, threats as global climate change, rising sea levels and many other totally unsustainable practices.  Mike held the view that only when man had the threat in his face equivalent to that of the attacking tiger would there be a wholesale change.

On the home page of this blog, I write,

As man’s companion, protector and helper, history suggests that dogs were critically important in man achieving success as a hunter-gatherer.  Dogs ‘teaching’ man to be so successful a hunter enabled evolution, some 20,000 years later, to farming,  thence the long journey to modern man.  But in the last, say 100 years, that farming spirit has become corrupted to the point where we see the planet’s plant and mineral resources as infinite.  Mankind is close to the edge of extinction, literally and spiritually.

In the context of homo sapiens, Latin for “wise man” or “knowing man”, then we know that modern man, anatomically, originated in Africa about 200,000 years ago.  Modern man only evolved from hunter/gatherer to farmer around 10,000 years ago, a tiny proportion of H. sapiens existence and, in evolutionary terms, no time at all.

The DNA of the domesticated dog separated from that of the wolf around 100,000 years ago.  No one knows for sure when man and dog came together but there is archaeological evidence of dogs being buried in mens’ graves around 30,000 years ago.  That’s an association over a huge time period.

Dennis and Mike, between them, triggered in my mind something fundamental.  Perhaps modern society, with all it’s bizarre behaviours and so many totally illogical practises (especially, in terms of a long-term relationship with our planet), could be understood.  Understood from the perspective of our social behaviours, built so much on technology, having raced far on to the point where they are now practically out of sight of our instinctive evolutionary behaviours.  We really don’t know how to change those core behaviours.

In contrast, dogs have remained much more stable with regard to their evolutionary progress and their external world.  Consider that the last big change for the domesticated dog was the association with man and that is at least three times as long ago as man becoming farming man.  No wonder when we curl up with our dog it has echoes of a time thousands of years before we could even spell the word, ‘politician’.  Echoes of a stability that seems now so way beyond reach.

Sceptical voices, part two

More musings about determining the truth.

Those who read yesterday’s part one will undoubtedly have seen the added comment from long-time friend of Learning from Dogs, Patrice Ayme.  Yesterday, I promised to conclude Dan’s sceptical approach to climate warming with three articles that he had sent me.  Here they are,

Global Warming

“Global warming” refers to the global-average temperature increase that has been observed over the last one hundred years or more. But to many politicians and the public, the term carries the implication that mankind is responsible for that warming. This website describes evidence from my group’s government-funded research that suggests global warming is mostly natural, and that the climate system is quite insensitive to humanity’s greenhouse gas emissions and aerosol pollution.

Believe it or not, very little research has ever been funded to search for natural mechanisms of warming…it has simply been assumed that global warming is manmade. This assumption is rather easy for scientists since we do not have enough accurate global data for a long enough period of time to see whether there are natural warming mechanisms at work.

The United Nation’s Intergovernmental Panel on Climate Change (IPCC) claims that the only way they can get their computerized climate models to produce the observed warming is with anthropogenic (human-caused) pollution. But they’re not going to find something if they don’t search for it. More than one scientist has asked me, “What else COULD it be?” Well, the answer to that takes a little digging… and as I show, one doesn’t have to dig very far.

But first let’s examine the basics of why so many scientists think global warming is manmade. Earth’s atmosphere contains natural greenhouse gases (mostly water vapor, carbon dioxide, and methane) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. Greenhouse gases trap infrared radiation — the radiant heat energy that the Earth naturally emits to outer space in response to solar heating. Mankind’s burning of fossil fuels (mostly coal, petroleum, and natural gas) releases carbon dioxide into the atmosphere and this is believed to be enhancing the Earth’s natural greenhouse effect. As of 2008, the concentration of carbon dioxide in the atmosphere was about 40% to 45% higher than it was before the start of the industrial revolution in the 1800’s.

It is interesting to note that, even though carbon dioxide is necessary for life on Earth to exist, there is precious little of it in Earth’s atmosphere. As of 2008, only 39 out of every 100,000 molecules of air were CO2, and it will take mankind’s CO2 emissions 5 more years to increase that number by 1, to 40.

Earth's atmosphere

The “Holy Grail”: Climate Sensitivity Figuring out how much past warming is due to mankind, and how much more we can expect in the future, depends upon something called “climate sensitivity”. This is the temperature response of the Earth to a given amount of ‘radiative forcing’, of which there are two kinds: a change in either the amount of sunlight absorbed by the Earth, or in the infrared energy the Earth emits to outer space.

The ‘consensus’ of opinion is that the Earth’s climate sensitivity is quite high, and so warming of about 0.25 deg. C to 0.5 deg. C (about 0.5 deg. F to 0.9 deg. F) every 10 years can be expected for as long as mankind continues to use fossil fuels as our primary source of energy. NASA’s James Hansen claims that climate sensitivity is very high, and that we have already put too much extra CO2 in the atmosphere. Presumably this is why he and Al Gore are campaigning for a moratorium on the construction of any more coal-fired power plants in the U.S.

You would think that we’d know the Earth’s ‘climate sensitivity’ by now, but it has been surprisingly difficult to determine. How atmospheric processes like clouds and precipitation systems respond to warming is critical, as they are either amplifying the warming, or reducing it. This website currently concentrates on the response of clouds to warming, an issue which I am now convinced the scientific community has totally misinterpreted when they have measured natural, year-to-year fluctuations in the climate system. As a result of that confusion, they have the mistaken belief that climate sensitivity is high, when in fact the satellite evidence suggests climate sensitivity is low.

The case for natural climate change I also present an analysis of the Pacific Decadal Oscillation which shows that most climate change might well be the result of….the climate system itself! Because small, chaotic fluctuations in atmospheric and oceanic circulation systems can cause small changes in global average cloudiness, this is all that is necessary to cause climate change. You don’t need the sun, or any other ‘external’ influence (although these are also possible…but for now I’ll let others work on that). It is simply what the climate system does. This is actually quite easy for meteorologists to believe, since we understand how complex weather processes are. Your local TV meteorologist is probably a closet ’skeptic’ regarding mankind’s influence on climate.

Climate change — it happens, with or without our help.

Earth may be headed into a mini Ice Age within a decade

Physicists say sunspot cycle is ‘going into hibernation’

By Lewis Page

Posted in Science, 14th June 2011 17:00 GMT

What may be the science story of the century is breaking this evening, as heavyweight US solar physicists announce that the Sun appears to be headed into a lengthy spell of low activity, which could mean that the Earth – far from facing a global warming problem– is actually headed into a mini Ice Age.

Ice skating on the Thames by 2025?

The announcement made on 14 June (18:00 UK time) comes from scientists at the US National Solar Observatory (NSO) and US Air Force Research Laboratory. Three different analyses of the Sun’s recent behaviour all indicate that a period of unusually low solar activity may be about to begin.

The Sun normally follows an 11-year cycle of activity. The current cycle, Cycle 24, is now supposed to be ramping up towards maximum strength. Increased numbers of sunspots and other indications ought to be happening: but in fact results so far are most disappointing. Scientists at the NSO now suspect, based on data showing decades-long trends leading to this point, that Cycle 25 may not happen at all.

This could have major implications for the Earth’s climate. According to a statement issued by the NSO, announcing the research:

An immediate question is whether this slowdown presages a second Maunder Minimum, a 70-year period with virtually no sunspots [which occurred] during 1645-1715.

As NASA notes [1]:

Early records of sunspots indicate that the Sun went through a period of inactivity in the late 17th century. Very few sunspots were seen on the Sun from about 1645 to 1715. Although the observations were not as extensive as in later years, the Sun was in fact well observed during this time and this lack of sunspots is well documented. This period of solar inactivity also corresponds to a climatic period called the “Little Ice Age” when rivers that are normally ice-free froze and snow fields remained year-round at lower altitudes. There is evidence that the Sun has had similar periods of inactivity in the more distant past.

During the Maunder Minimum and for periods either side of it, many European rivers which are ice-free today – including the Thames – routinely froze over, allowing ice skating and even for armies to march across them in some cases.

“This is highly unusual and unexpected,” says Dr Frank Hill of the NSO. “But the fact that three completely different views of the Sun point in the same direction is a powerful indicator that the sunspot cycle may be going into hibernation.”

Hill’s own research focuses on surface pulsations of the Sun and their relationship with sunspots, and his team has already used their methods to successfully predict the late onset of Cycle 24.

“We expected to see the start of the zonal flow for Cycle 25 by now,” Hill explained, “but we see no sign of it. This indicates that the start of Cycle 25 may be delayed to 2021 or 2022, or may not happen at all.”

Hill’s results match those from physicists Matt Penn and William Livingston, who have gone over 13 years of sunspot data from the McMath-Pierce Telescope at Kitt Peak in Arizona. They have seen the strength of the magnetic fields which create sunspots declining steadily. According to the NSO:

Penn and Livingston observed that the average field strength declined about 50 gauss per year during Cycle 23 and now in Cycle 24. They also observed that spot temperatures have risen exactly as expected for such changes in the magnetic field. If the trend continues, the field strength will drop below the 1,500 gauss threshold and spots will largely disappear as the magnetic field is no longer strong enough to overcome convective forces on the solar surface.

In parallel with this comes research from the US Air Force’s studies of the solar corona. Richard Altrock, in charge of this, has found a 40-year decline in the “rush to the poles” – the poleward surge of magnetic activity in the corona.

“Those wonderful, delicate coronal features are actually powerful, robust magnetic structures rooted in the interior of the Sun,” Altrock says. “Changes we see in the corona reflect changes deep inside the Sun …

“Cycle 24 started out late and slow and may not be strong enough to create a rush to the poles, indicating we’ll see a very weak solar maximum in 2013, if at all. If the rush to the poles fails to complete, this creates a tremendous dilemma for the theorists … No one knows what the Sun will do in that case.”

According to the collective wisdom of the NSO, another Maunder Minimum may very well be on the cards.

“If we are right,” summarises Hill, “this could be the last solar maximum we’ll see for a few decades. That would affect everything from space exploration to Earth’s climate.”

The effects on space exploration would be benign, as fewer or no solar storms would make space a much less hostile environment for human beings. At the moment, anyone venturing beyond the Earth’s protective magnetic field (the only people to have done so were the Apollo moon astronauts of the 1960s and ’70s) runs a severe risk of dangerous or fatal radiation exposure during a solar storm.

Manned missions beyond low Earth orbit, a stated aspiration of the USA and other nations, might become significantly safer and cheaper to mount (cheaper as there would be no requirement for possibly very heavy shielding to protect astronauts, so reducing launch costs).

The big consequences of a major solar calm spell, however, would be climatic. The next few generations of humanity might not find themselves trying to cope with global warming but rather with a significant cooling. This could overturn decades of received wisdom on such things as CO2 emissions, and lead to radical shifts in government policy worldwide.

On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth’s Radiant Energy Balance

* Author to whom correspondence should be addressed.Received: 24 May 2011; in revised form: 13 July 2011 / Accepted: 15 July 2011 / Published: 25 July 2011

Abstract: The sensitivity of the climate system to an imposed radiative imbalance remains the largest source of uncertainty in projections of future anthropogenic climate change. Here we present further evidence that this uncertainty from an observational perspective is largely due to the masking of the radiative feedback signal by internal radiative forcing, probably due to natural cloud variations. That these internal radiative forcings exist and likely corrupt feedback diagnosis is demonstrated with lag regression analysis of satellite and coupled climate model data, interpreted with a simple forcing-feedback model. While the satellite-based metrics for the period 2000–2010 depart substantially in the direction of lower climate sensitivity from those similarly computed from coupled climate models, we find that, with traditional methods, it is not possible to accurately quantify this discrepancy in terms of the feedbacks which determine climate sensitivity. It is concluded that atmospheric feedback diagnosis of the climate system remains an unsolved problem, due primarily to the inability to distinguish between radiative forcing and radiative feedback in satellite radiative budget observations.

So back to me!

As you can see there is every opportunity to be confused.  Not embracing contrary views to the ones that you believe, however, is not the way to determine the truth.

So let me close with a couple of my own contrary views.

The first from Bill McKibben published in the Resurgence Magazine,

WHAT COMES NEXT?

We have a tiny window of opportunity to save something of the magnificence of the Earth so let’s all grab it, writes Bill McKibben, founder of 350.org

Asked to name the biggest thing that’s happened over Resurgence’s 45-year career, I think I’d have to say the melt of the Arctic. When this magazine began publishing, there was 40% more summer sea ice in the Arctic. Viewed from space, in those first pictures from the Apollo spacecraft, the planet looked very different than it does now. In recent summers both the north-west and the north-east passages have opened, allowing sailors to circumnavigate the Arctic through waters that no one thought, even a decade ago, humans would ever navigate.

Or maybe I would pick the rapid acidification of the planet’s seas – they’re 30% more acid than they were in 1966. Which means that the small creatures at the base of the marine food chain are having more trouble forming their shells, and that coral reefs – already stressed by warming waters – have a new trauma to deal with.

Another possibility: the Earth’s atmosphere is about 4% moister than it was 45 years ago, simply because warm air holds more water vapour than cold. This loads the dice for deluge, downpour, flood – it’s not surprising that we’re seeing record rainfall and unprecedented floods. Nor, since that water has to come from somewhere, should increasing drought and desertification come as much of a shock.

Here’s what I’m trying to say: when Resurgence began its run, we were still in the Holocene. Humans had altered much of the planet’s natural environment. We had dirty rivers and dirty air, spreading toxins and endangered species. But the basic operating system of the planet was running pretty much the same as it had for the 10,000 years of human civilisation.

Sometime in the intervening decades we moved out of that comfortable and remarkably stable world, and began the transition to What Comes Next?

Any date would be arbitrary, but if you wanted to pick one, you could say 1988. That was the year NASA scientist Jim Hansen warned the US Congress that global warming was indeed real – and it was the year that we passed the benchmark of 350 parts per million (ppm) of CO2 in the atmosphere. At the time we didn’t know it was a benchmark – it was 20 years later that scientists, again led by Hansen, declared that 350ppm was the absolute upper limit if we wanted a planet “similar to the one on which civilisation developed and to which life is adapted”. If we wanted, in other words, that older world we were born onto.

I could list at some length the various woes this new world is already causing: we see rising sea levels displacing farmers across the deltas of Bangladesh, and Aedes aegypti expanding its boundary and spreading dengue fever like wildfire. Speaking of wildfire, we see record amounts, in part because of more heat and drought, and in part because insects (once kept in check by cold weather) are now spreading.

We see millions still homeless from last year’s flood in Pakistan, and billions struggling to pay for food because a string of crop failures that began with last summer’s Russian drought have increased grain prices by 70–80%.

And I could list at even greater length the woes we expect as the century grinds on. After all, we’ve only raised the temperature about a degree so far, and the climatologists tell us to expect four or five unless we stop burning coal and oil and gas much faster than any government currently plans. Temperatures like that will guarantee the melt of Greenland; according to the agronomists they will cut grain harvests by a third or more; they’ll make current shortages of water seem barely worth mentioning.

But for the moment don’t think about consequences, current or future. Just think about the enormity of what we’ve managed to do: we’ve altered the most basic operations of the one planet we’ve got.

The air is profoundly different, the heat balance with our sun profoundly altered. It’s by far the biggest thing humans have ever done or ever contemplated doing, and were some alien watching from a great distance she’d be scratching her head-like appendage. It’s our head-like appendage that’s responsible, of course. That big brain turned out to be incredibly clever, and its cleverest trick was to figure out that buried carbon could make life easy. Everything that we know around us – the whole modern world – derives from that discovery. Much of it is good. But now we’re threatening to take down the good, and much else with it.

So here’s the question for the next 45 years of Resurgence: can the big brain bail us out?

It’s already provided us with the warnings we need, warnings that would not have been available at any other moment in human history. The scientific method, one of the greatest achievements of our civilisation, has produced a robust consensus on this difficult problem in chemistry and physics: since the mid-1990s the Intergovernmental Panel on Climate Change (IPCC) has said in unmistakably plain language that there is no doubt: we have to cut carbon, and quickly.

But so far that warning has had little or no effect: our national governments, with a few noble exceptions, have paid scant attention; our attempts at global governance have been pathetic failures. The chief reason, I think, is the remarkable power of the fossil-fuel industry to stifle change; for 200 years it has grown bigger and richer and more than able to deal with the threat that science now poses to its reign. It literally makes us stupid: earlier this winter the US House of Representatives, by a 60-vote margin, defeated a resolution that merely stated that global warming was real. Exxon has promoted its own version of physics and chemistry, and they’ve managed to fool a good many too.

The real question, then, is going to be: is there a big enough heart connected to that big brain? Will we be able to heed not only the warnings of science but those of our conscience? Will we, gazing out at the growing array of ‘natural disasters’, figure out that we’ve got to make change? Change in our personal lives, yes, but even more change in our political arrangements, since that’s the only chance that actual physics and chemistry really give us for meeting the deadlines they’ve set.

I think the answer is yes – a tentative and uncertain yes, but one based on just enough real-world data to give me hope.

Three years ago we founded 350.org, the first big global grassroots climate campaign. Rooted in science but expressed in imagination, it has grown to pretty mammoth size. Our first two big global days of action, in the waning months of 2009 and 2010, were what CNN called “the most widespread days of political action in the planet’s history”, with nearly 15,000 demonstrations in every country on Earth but North Korea.

And the good news is we didn’t really ‘organise’ it – our tiny staff worked feverishly, but ultimately it was like a potluck supper. People in every corner of the Earth heard the call and did the work, figuring out what would work in their place. (An underwater demonstration on the dying coral reefs of the Maldives; a giant image of King Canute, composed of thousands of volunteers, trying to hold the sea back on the Brighton seashore!)

It’s not enough yet to beat the fossil-fuel industry – our bodies don’t yet add up to their money. But we’re growing constantly (the next big chance to join us: 24 September 2011, a day we’re calling Moving Planet). And – sad, but true – the natural world is going to continue to give us openings to make the case more strongly. Sooner or later our leaders will listen – and we’re committed to making it sooner.

We’re not going to stop global warming: it’s already warmed and it will warm some more. Those Apollo images of our planet are forever sepia-toned. But we’ve got a tiny window left to save something of the Earth we were born onto – its beauty, its bounty, its safety.

That’s our task, and the next 45 years will tell the tale.

Bill McKibben wrote the first book for a general audience on climate change, The End of Nature, in 1989. He is a scholar in residence at Middlebury College in Vermont.

Arctic ice hits second-lowest level, US scientists say

Sea ice cover in the Arctic in 2011 has passed its annual minimum, reaching the second-lowest level since satellite records began, US scientists say.

The National Snow and Ice Data Center (NSIDC) says the minimum, reached on 9 September, was 4.33 million sq km.

That value is 36% lower than the average minimum for 1979-2000.

NSIDC said the figure was preliminary, and that “changing winds could still push the ice extent lower” before final numbers are published in early October.

The preliminary value is 160,000 sq km – or 4% – above the record minimum seen in 2007.

The minimum level of cover is far below the average of 1979-2000

“While the record low year of 2007 was marked by a combination of weather conditions that favoured ice loss – including clearer skies, favourable wind patterns and warm temperatures – this year has shown more typical weather patterns but continued warmth over the Arctic,” they wrote.

“This supports the idea that the Arctic sea ice cover is continuing to thin.”

NSIDC director Mark Serreze said: “Every summer that we see a very low ice extent in September sets us up for a similar situation the following year.

“The Arctic sea ice cover is so thin now compared to 30 years ago that it just can’t take a hit any more. This overall pattern of thinning ice in the Arctic in recent decades is really starting to catch up with us.”

In fact, an analysis released last week by researchers at the University of Bremen in Germany, who use a different satellite to assess ice cover, indicated that 2011’s minimum was the lowest on record.

However, there is some controversy surrounding the result; the Bremen team’s higher-resolution data can detect small patches of water where the NSIDC team would not, but the Bremen record goes back only to 2003.

These analyses are for the extent, or area, of Arctic ice, but recent estimates released by the University of Washington’s Polar Science Center give an indication of the total amount of sea ice.

Their data indicate that the ice volume is at an all-time low for the second year in a row.

Analyses of Arctic ice in recent years consistently indicate a change in the nature of the ice itself – from one solid mass that melts and freezes at its edges towards more dispersed, piecemeal ice cover, and from robust “multi-year” ice toward seasonal floes that melt more easily.

The NSIDC data show ice cover extents consistently below earlier averages

You may want to refer to the worrying images of the Petermann Glacier that I published on the 14th September.

I hope this article, split over two days, has been useful.  Hopefully, they underline the need to work it out for yourself and remain open-minded at all times.

The Great Disruption by Paul Gilding

A book review

Unlike my recent review of Capt. Luis Montalvan’s book Until Tuesday which came about as a result of an invitation from the UK publishers, Headline Publishing, this review of Mr. Gilding’s book is totally off my own bat.  I should also declare that I have recently been in email contact with Paul Gilding with some pleasant outcomes.  To the review.

The way ahead.

Regular readers of Learning from Dogs will know that I have been making recent references to this book, which I have now finished reading.  On the 25th I quoted from the book in a post that I called The blame game.  I used a quote from Chapter 5, Addicted to Growth, namely “Growth goes to the core of the society we have built because it is the result of who we are and what we have decided to value.”

Then the next day again when writing about Tim Bennett’s movie, What a Way To Go, when I reflected on Paul Gilding’s opinion that, ” the quicker that mankind recognises the massive levels of denial presently in place, the quicker that mankind will commit to the scale of change that is required“.

Now if mankind’s efforts to change to a sustainable way of life were proportional to the number of books, films and essays written about the subject then, frankly, the task would be complete.  There’s an awful lot out there!  Here’s a list of the books that I have read in the last few years:

The Human Side of Enterprise – Douglas McGregor

Motivation and Personality – Abraham Maslow

The Power of Pause – Terry Hershey

Earth in the Balance – Al Gore

The Spectrum of Consciousness – Ken Wilber

Politics Lost – Joe Klein

Why America Doesn’t Work – Chuck Colson & Jack Eckerd

The Art of Happiness – HH Dalai Lama & Howard C Cutler

Eaarth – Bill McKibben

Stabilizing an Unstable Economy – Hyman P. Minsky

The Next 100 Years – George Friedman

World of the Edge – Lester Brown

and finally

The Great Disruption – Paul Gilding

And, of course, this doesn’t even scratch the number of online journals, essays and articles that have been read in conjunction with writing hundreds of posts on this Blog.

So what’s the point?

On p.260, Chapter 20 Guess Who’s in Charge?, Paul Gilding writes,

We need to fully acknowledge the challenging times and inevitable suffering ahead but stay focused and determined to move forward and past this.  Easy to say, harder to do.

So yes, it is challenging to know how to respond to all this and what to do personally.  It is easy to see what the world should do, but what should you do?

but what should you do? Talk about a thump on the back of the head!

This is about me!

Of all the books that have influenced how I see the world and my opinions, the one book that has rammed home to me that this is about me, about my attitudes and behaviours, is The Great Disruption.  For a long time I haven’t needed convincing that man is screwing up the planet.  For ages, I’ve been sure that our greed and materialism were fundamentally incompatible with the planet. I have been so good at ‘talking the talk’ ….. but ….

But the way that Mr. Gilding has so comprehensively approached every aspect of how my past behaviours have been incompatible with the future needs of my little grandson, Morten, (and all the grandchildren in the world) is powerfully inspiring.  I now totally and utterly believe that only I am in charge of making a difference.

Why The Great Disruption touched me in this way when so many other books and articles haven’t done so isn’t clear.  Perhaps it was in the opening paragraphs?

The earth is full.

[skip one paragraph]

This means things are going to change.  Not because we will choose change out of philosophical or political preference, but because if we don’t transform our society and economy, we risk social and economic collapse and the descent into chaos.  The science on this is now clear and accepted by any rational observer.  While an initial look at the public debate may suggest controversy, any serious examination of the peer-reviewed conclusions of leading science bodies shows the core direction we are heading in is now clear.  Things do not look good.

These challenges and the facts  behind them are well-known by experts and leaders around the world, and have been for decades.  But despite this understanding, that we would at some point pass the limits to growth, it has been continually filed away to the back of our mind and the back of our drawers, with the label “Interesting – For Consideration Later” prominently attached.  Well, later has arrived.

I nodded silently in agreement when reading that.

Was it the opening paragraph to Chapter 4, Beyond the Limits – The Great Disruption?

The plans we have been making for our economies, our companies, and our lives have all been based on a key assumption that is clearly wrong.  This assumption is that our current economic model will carry on unless we choose to change it – in other words, no action means more of the same.

This resonated strongly with me because I happen to believe, without any specialist economic skills to my name – just a gut sense, that the economic situation now afflicting so many economies across the world is not cyclical but the start of a breakdown of the policies and behaviours of the last 20 years or more.  In other words, the Great Disruption was in my face already!  As is written on p. 87 in Chapter 6, Global Foreshock – The Year That Growth Stopped,

My view, firmly held at the time and since, is that 2008 was the year that growth stopped.  It was the year, as Thomas Friedman said, “when Mother Nature and Father Greed hit the wall at once”.

The Power of a New Future

But, in the end, the real power that I found in this book was the strength of Gilding’s argument that we will change, that seeing the future as hopeless is wrong, that man has the ability to commit to huge change when there is no alternative.  Ergo, p121 Chapter 9 When the Dam of Denial Breaks,

To argue we are naturally greedy and competitive and can’t change is like arguing that we engage naturally in murder and infanticide as our forebears the chimps do and therefore as we did.  We have certain tendencies in our genes, but unlike other creatures we have the proven capacity to make conscious decisions to overcome them and also the proven ability to build a society with laws and values to enshrine and, critically, to enforce such changes when these tendencies come to the surface.

So don’t underestimate how profoundly we can change.  We are still capable of evolution, including conscious evolution.  This coming crisis is perhaps the greatest opportunity in millennia for a step change in human society.

This quote is towards the end of the last chapter that spells out, as so many other books have done, that our global society Has a Very Big Problem.  Thus from page 123 onwards, slightly less than half-way through the book, Paul Gilding devotes huge detail to describing how we will change.  Frequently, the comparison used is World War II,

British poster from 1940

When Great Britain went to war in World War II, do you think they had clarity on all the details of transitioning into a war economy before they made the decision to act?  Of course they considered it, as we must, but it wasn’t a determining issue because there was no choice.  Do you think President Roosevelt calculated the United States could win the war by increasing military spending to 37 percent of U.S. GDP and producing a nuclear bomb before he decided to enter the war?  Of course not: he just knew they had to succeed and so they would.  He had confidence in human ingenuity delivering under pressure, when it’s given defined parameters and political support, and so must we.

From p. 164, Chapter 12 Creative Destruction on Steroids.

That’s what ended up being the real inspiration for me.  That it’s not about the complex problems looming large; as so many that Jean and I chat to here in Payson, AZ, readily admit to being worried.  It’s not news! The majority of the world’s citizens know the trends are not good.

No, what really socked me between the eyes was reading all the many and varied ways that we are changing (note present tense), that the Great Disruption is, in fact, mankind moving to a new era.  One where we will have less inequality, less poverty, be happier, have extended life-spans and a future that goes on for thousand of years.

The Future is Here.

The phrase ‘life-changing’ is often used but this book is truly life-changing.  The book will motivate you in ways that you can’t imagine.  It will inspire you but, above all, it will show you the way ahead.  Read it.

Well done, Mr. Gilding.  Well done, indeed!

Mr. Paul Gilding

The unexplored shores of the future

A focus on Tim Bennett’s movie, What a Way To Go: Life at the end of Empire

We first came across this film, made by independent film-maker Tim Bennett, on the Top Documentary Films website, see here.  The title to this article comes from that introduction, from which is quoted,

Tim Bennett, middle-class white guy, started waking up to the global environmental nightmare in the mid-1980s. But life was so busy with raising kids and pursuing the American dream that he never got around to acting on his concerns. Until now…

Bennett journeys from complacency to consciousness in his feature-length documentary, What a Way To Go: Life at the End of Empire. He reviews his Midwestern roots, ruthlessly examines the stories he was raised with, and then details the grim realities humans now face: escalating climate change, resource shortages, degraded ecosystems, an exploding global population and teetering global economies.

Now to be honest, this is a film that is both captivating and, in parts, pretty grim.  A couple of trailers and other background material were posted on Learning from Dogs back in February.

The film also has an excellent web site What a Way To Go Movie which contains much background material including the opportunity to watch the film for free, click here.  Or a quick YouTube search will bring you to here.

My own view is that this is a ‘must see’ film.  Not because I want all of you to wallow in doom and gloom, far from it, but because, as Paul Gilding writes in his book, The Great Disruption, the quicker that mankind recognises the massive levels of denial presently in place, the quicker that mankind will commit to the scale of change that is required.  That’s where Paul Gilding’s approach differs from the movie, The End of Empire.  Gilding is optimistic that man will bring about change simply because fairly soon, in just a few years, it will be obvious at all levels in our societies that there simply is no choice!

Sanity out of insanity

Dogs are such a great metaphor!

There’s no question that when one stays very still and closely watches a dog’s behaviour you see an amazing level of awareness.  Even when they appear to be deeply asleep anything sensed by their ‘being’ is registered immediately.  A small tale, by way of example.  Many years ago when Pharaoh and I lived in the Devon village of Harberton, we  frequently shopped in the town of Totnes, just 3 miles away.  Many times, I would be walking up the High Street with Pharaoh nicely to heel being passed by many people walking the opposite way on the same pavement.

Totnes High Street

Every once in a while, during the fraction of time that it took for someone to pass us by, Pharaoh would utter a low, throatal growl without even slowing his pace.  I always presumed that something, way beyond my level of consciousness, had disturbed Pharaoh during that instant of time.

Real awareness, or if you prefer, consciousness is not some touchy/feely concept but a true understanding about just what the heck is going on.

So do watch the following video of Peter Russell discussing Rediscovering Ourselves; it’s very relevant.

Then have a read of a couple of items on Peter’s website.  The first is about runaway climate change, and here’s an extract,

Runaway Climate Change

The most dangerous aspect of global warming.

Global Warming is bad enough. Over the last hundred years, average global temperatures have increased by 0.75°C, one third of that rise occurring in the last twenty years. The 2007 report by The Intergovernmental Panel of Climate Change (IPCC) forecast that, by 2090, temperatures will have risen between 2 and 6 degrees.

Even a two degree rise in temperature would be disastrous. Changes in climate will lead to more intense storms, longer periods of drought, crop failures in many developing countries, the destruction of nearly all the coral reefs, the melting of much of the polar ice, the flooding of many low-lying urban areas, the possible collapse of the Amazonian rain forest, and the extinction of 20-30% of the planet’s species. The IPCC projects that this could happen by 2050.

If the temperature were to rise by six degrees, the prognosis is extremely bleak. At this temperature, the entire planet will be ice-free. Sea levels will rise by 70 meters. Many species of tiny plankton will cease to exist, and the problem would echo up the food chain, bringing the extinction of many fish, sea mammals, and the largest whales. Much of the land will now be desert. Hurricanes of unimaginable ferocity will bring widespread ecological devastation. If, as is possible, the ozone layer were destroyed, the burning ultraviolet light could make life on land impossible. Evolution would have been set back a billion years. It would be a planetary catastrophe.

Read the rest of that essay here.  Now on to the next extract, from here,

The Under-rated Approach to Carbon Reduction

As critical as it is to reduce future carbon emissions, it is equally critical, perhaps even more critical, to get much of the CO2 that as already been released—and which is responsible for the current warming—out of the atmosphere and back into the ground where it belongs.

This approach, known as carbon capture and sequestration, has until now been largely ignored, and for several reasons. The atmosphere is so huge, it would seem to be an impossible task. There are possible technologies, but they are not nearly so well-developed as alternative energy sources. Many are still only ideas on paper. Where technologies of carbon capture have been developed they are mostly for capturing CO2 from smokestacks. Valuable as this may be, it is still dealing with the problem of future carbon emissions. What we need are technologies that will remove from the atmosphere the carbon that we already emitted, and then sequestrate it (put it away) in a stable form.

It is to this end that Sir Richard Branson announced his $25 million prize (Virgin Earth Challenge) for technologies that could capture a billion tons of carbon a year from the atmosphere (about one tenth of what we now release each year). Nor is it just Richard Branson who believes we must make this an equally important approach to the problem. His team includes Al Gore, James Lovelock, Sir Crispin Tickell (former UK ambassador to the UN), and James Hansen, the head climate scientist at NASA).

Again, the full article, a ‘must-read, in my opinion, is here.

It is really about awareness!  Dogs have so much to teach us!

Global climate confusion, part two.

More on the many and varied approaches to this complex subject.  Again, a long piece which, dear reader, I hope you will stay with.

As I wrote in response to Per Kurowski’s comment on yesterday’s Part One of this article, ” I am reminded of the saying that in war the first casualty is truth. It ‘feels’a lot like that in this scenario.”

Part Two isn’t attempting to indicate the truth, just the many opinions out there.

First, let me quote an email that Patrice sent to me late last night,

Hi Paul!

I think that the propaganda from the fossil fuel and other feudal plutocracies have confused the issue. The primary problem is not “climate change” (aka planetary heating/broiling).I am not confused, because it’s NOT about climate change. Climate change is a second order effect. It may, or may not happen, short term.

The gist of my essay is that climate change will NOT happen, short term, if the sun cools down spectacularly, as it did TWICE in the last five centuries (~ Little Ice Age).

The way to look at things correctly, thus, is CO2 POISONING. Even if the sun cooled down spectacularly, as I emphasized, the ACIDIFICATION of the oceans would proceed unabated. After killing the oceans, if the sun goes back to normal, the greenhouse would rebound enormously.

Although I did not speak of it in that particular essay, we now know the rate of CO2 in the atmosphere, through shell formation in the ocean, for at least 20 million years (and soon at least 100 million; the method should work for half a billion years!). Thus we know the level of CO2 equivalent is the highest in 20 million years (although some have claimed that transitory fluxes much higher than that have occured, from volcanoes; that would not be a problem, as a high flux does not allow storage in the oceans!)

Feel free to quote from this, I just thought of this formulation now, and it may help clarify matters (and it is clearly the idea of the essay).  BTW, let me emphasize that my essay explains why FLOODING, by no means certain on a proxymal massive scale, is, however a clear possibility. London under water seems even a near certainty on the scale of a century (but for enormous works, requiring huge energy!)

Patrice

OK, a useful footnote to yesterday’s piece.  But then if one goes back to Patrice’s original article on his Blog on 31st May, 2009 and reads the comments, you find this, (and I’m going to quote entirely from Mr Day’s comments).

Barry Day says

(QUOTE)What does this mean? We should be cooling down, because the sun’s output has been going down as much as an astounding 6% in some frequencies. But, nevertheless, the lower troposphere has been warming up (END QUOTE)

Ever heard of lag?

“New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.”

“This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.”  From Pysorg.com of November 10th, 2009.

Then Barry Day looks at earthquakes,

From EARTHQUAKES – WHAT ARE THE LONG TERM TRENDS?

“Apart from the “long-term” trends shown above, which show an ongoing persistent increase, it is perhaps more stark to record that earthquakes across the planet show a marked increase in activity since 1997. There are more major earthquakes occurring now, and this on an ever more frequent basis.”

From Worldwide Earthquakes [Magnitude 6 to 9.9] have increased by 47 percent in under 3 decades

“A total of  1,085 earthquakes measuring magnitude 6 or greater occurred between 1980 to 1989, averaging 109 per year over the decade. In the 1990s the decadal total increased to 1,492 averaging at 149 major earthquake  per year over the period.

Since January 1, 2000 [ see table below for the date and time] a total of 1,438 major earthquakes have so far occurred worldwide raising the annual total over the last 9 years to 160 with more than 12 and a half months to go to the decade’s end.

The increase from 109 to 160 major earthquakes per year in the 1980 to 2008 period translates to a rise  of 47 percent in just under three decades.” [This reference is dated December 13th, 2008, before the Japanese earthquake, Ed.]

The Barry Day goes on to highlight these references,

From MISTAKES IN IPCC GLOBAL WARMING CALCULATIONS

Abstract
The United Nations Intergovernmental Panel on Climate Change (IPCC) released its Fourth Assessment Report (AR4) in 2007. Here we show that the accurate value for climate sensitivity is 0.277 K/(W/m^2), which is 3 times smaller than the generally accepted value of 0.8 K/(W/m^2). Thus the climate change on doubling CO2 from 300 ppm to 600 ppm will be 1.0 degree, not 3 degrees. Because the IPCC data show that doubling CO2 will not double absorption of infrared radiation, the Beer-Lambert law is not being followed, because of diminishing returns after more-than-50% absorption.

[This is an extremely difficult essay for a non-scientist to follow.  All I can do is to include the source of the article, as below, Ed.]

This article by Roger Taguchi, 234 Knox Crescent, Ottawa, Ontario, Canada K1G 0K8, e-mail address rtaguchi@sympatico.ca, was posted on Monday Aug. 31, 2009.

Then Barry adds another comment,

We’ve forgotten that this isn’t the first time our seas have warmed. Sea temperatures also shot upward 10º to 18ºF just prior to the last ice age.

As the oceans warmed, evaporation increased. The excess moisture then fell to the ground as giant blizzards, giant storms and floods (Noah’s Deluge type floods), and a new ice age began.

The same thing is happening today.

It’s not global warming, it’s ocean warming, and humans have nothing to do with it. Our seas are being heated, I believe, by underwater volcanism. Here’s why:

We are living in a period of vastly increased volcanism, said Dixy Lee Ray in her 1993 book Environmental Overkill, the greatest in 500 years. Eighty percent of all volcanism (say experts at NOAA) occurs underwater. Therefore, underwater volcanism should also be the greatest in 500 years.

Our seas, heated by underwater volcanism, are leading us directly into the next ice age . . . and we don’t even know it.
That’s what El Niño is all about. Warmer seas send excess moisture into the sky, leading to increased precipitation.
Worldwide flood activity is the worst since before Christopher Columbus. In Poland, it’s the worst in several thousand years. In the U.S., precipitation has increased 20 percent just since 1970. This is no coincidence.

When that precipitation begins falling in the winter, you have the makings of an ice age.

Here are some further references,

From the Nature website of 29th March, 2001,

South America’s oldest trees give up the ghost of climate past.

They’ve been dead for over 50,000 years, but South America’s longest-living trees still have a few tales to tell. A new study of the growth rings of partially fossilized trees in southern Chile hints that the global climate before the last ice age was rather like today’s.

Barry mentions Kavachi Island and I did a quick search and came up with this.

From Wikipedia,

Kavachi is one of the most active submarine volcanoes in the south-west Pacific Ocean. Located south of Vangunu Island in the Solomon Islands, it is named after a sea god of the New Georgia Group islanders, and is also referred to locally as Rejo te Kavachi (“Kavachi’s oven’). The volcano has become emergent and then been eroded back into the sea at least eight times since its first recorded eruption in 1939.

In May 2000, an international research team aboard the CSIRO research vessel FRANKLIN fixed the position of the volcano at 8° 59.65’S, 157° 58.23’E. At that time the vent of the volcano was below sea level, however frequent eruptions were ejecting molten lava up to 70m above sea level, and sulfurous steam plumes up to 500m. The team mapped a roughly conical feature rising from 1,100 m water depth, with the volcano having a basal diameter of about 8 km.

When the volcano erupted in 2003, a 15-meter-high island formed above the surface, but it disappeared soon after. Additional eruptive activity was observed and reported in March 2004 and April 2007.

Kavachi erupting May 14th, 2000.

Barry then looks as CO2 levels, he writes,

Carbon dioxide
If today’s rising carbon dioxide are caused by humans, what caused the dramatic rise in CO2 levels at the dinosaur extinction?

It was a matter of a moment’s search to find this, from Ice Age Now, Home Page here

If today’s rising carbon dioxide are caused by humans, then what caused the dramatic rise in CO2 levels at the dinosaur extinction? 

Research shows that there was “a sudden and dramatic rise” in carbon dioxide in the Earth’s atmosphere at the dinosaur extinction of 65 million years ago. A recent report attributes the rise in CO2 levels to an asteroid impact.
See http://news.bbc.co.uk/1/hi/sci/tech/2038599.stm

I disagree. I think today’s rise in CO2 levels can be attributed to our warming oceans. After all, the oceans are known as a carbon dioxide “sink,” especially when the water is cold. 

But as the water warms up, it releases CO2 into the atmosphere. This happens in much the same way that a warm bottle of home-brewed root beer will release CO2. And if you give that CO2 no way to escape, the bottle will explode.

We’ve got it backwards. We’ve got cause and effect in reverse.

The CO2 is not causing global warming. Instead, our warming oceans are releasing CO2 into the atmosphere.

It’s not global warming, it’s ocean warming, and it’s leading us into an ice age.

Finally, Barry offers this,

No Global Warming
“Even with needed corrections, data still don’t show the expected signature of global warming,” says Dr. Roy Spencer, Senior Scientist for Climate Studies NASA/Marshall Space Flight Center.

Unfortunately, the URL that Barry included didn’t function.  But a quick search on the NASA website came up with this,

Contrary Thermometers

Scientists are working to understand why the lower atmosphere isn’t heating up as fast as some global warming models predict.

July 21, 2000 — The question sounds like a Zen koan: How could the globe be warming and not warming at the same time?

That’s the riddle posed to climatologists by satellite and radiosonde data which show that while the Earth’s surface has been warming over the past decades, the lowest layer of the atmosphere shows a weaker warming trend.

The measurements are surprising, because computer simulations of the world’s climate predict that the two lowest layers of the atmosphere — which together form the “troposphere” — should be warming faster than the Earth’s surface.

Read the full article here.  It’s well worth reading and concludes with these closing paragraphs,

Current models suffer from several shortcomings.

For example, clouds are not well represented by the models. The resolution of current models is too coarse for features as small as clouds, Spencer said. Yet clouds clearly play a crucial role in climate due to their influence on humidity, precipitation and albedo (the percentage of solar energy reflected back into space as light).

“The role of clouds is still regarded as one of the biggest uncertainties in global warming predictions,” Spencer said.

The ability of plants to remove carbon dioxide from the atmosphere and the role of soils have only recently been added to the models, and scientists aren’t confident yet of how the models portray these factors, Spencer said.

“While we know that vegetation takes up some of the carbon dioxide we generate from burning of fossil fuels, how that sink of carbon will change in the future is still pretty uncertain,” Spencer said.

Climate models are also limited by the computing power available.

“The global models would be much better if computers were much faster,” Spencer said. “Instead, a lot of approximations are made to make the models simple enough to do climate simulations over the whole globe.

“Unfortunately,” Spencer continued, “we know that many of the processes that are crudely represented are quite non-linear, and so have the potential to respond in unexpected ways.”

The Global Hydrology and Climate Center is a joint venture between government and academia to study the global water cycle and its effect on Earth’s climate. Jointly funded by NASA and its academic partners, and jointly operated by NASA’s Marshall Space Flight Center in Huntsville, Ala., and the University of Alabama in Huntsville, the Center conducts research in a number of critical areas.

OK, that’s enough from me for today.  Clearly it would take a great time for a layman, such as yours truly, to go through all this material, and more, to determine the truth of it all, to the very best abilities of science.  For the verdict on whether man’s increased generation of CO2 in the atmosphere is having a global effect on the global climate should be in the hands of scientists.

Once science has shown cause and effect then, and only then, should politicians endeavour to offer the way forward for society.

Having said that, there is no reason at all for mankind to maintain the present disconnect from Planet Earth.  Even if the jury is still well and truly out in terms of the effect of CO2 on the atmosphere, the number of other issues that are just as important for our long-term survival are still prodigious.  There’s an old saying in aviation, “If there’s any doubt, there’s no doubt.”
