Reading Planet Earth, part Two

The second of an unmissable series of four 1-hour videos from National Geographic.

The background and introduction to the first episode was published yesterday.  So I won’t natter on today saying more or less the same thing.

But I will add this thought.

The videos are tough viewing but compelling because they show the complexity and inter-relatedness of all forms of life on our Planet.  It shows that the debate about climate change/global warming/call it what you will is not a simplistic do you or do you not believe mankind is at the root of the changes.  No it’s a much more complex question about the threat to our whole biosphere, as Patrice Ayme so eloquently spelt out on March 2nd.  These videos make that crystal clear.

Here’s the second episode,

National Geographic – Strange Days on Planet Earth – Part 2 of 4 – One Degree Factor

I must go down to the sea again, spelt H2CO3!

Starting to feel like a long way from John Masefield’s poem Sea Fever.

The call of the sea.

One of my all-time favourite poems.

I must go down to the seas again, to the lonely sea and the sky,
And all I ask is a tall ship and a star to steer her by,
And the wheel’s kick and the wind’s song and the white sail’s shaking,
And a grey mist on the sea’s face, and a grey dawn breaking.

I must go down to the seas again, for the call of the running tide
Is a wild call and a clear call that may not be denied;
And all I ask is a windy day with the white clouds flying,
And the flung spray and the blown spume, and the sea-gulls crying.

I must go down to the seas again, to the vagrant gypsy life,
To the gull’s way and the whale’s way, where the wind’s like a whetted knife;
And all I ask is a merry yarn from a laughing fellow-rover,
And quiet sleep and a sweet dream when the long trick’s over.

Why do I start this piece with that poem?

Well, read this,

Carbonic acid is a weak acid that is created when carbon dioxide (CO2) is dissolved in water (H2O), resulting in the chemical formula H2CO3. When the acid dissociates, or gives up a hydrogen ion, the resulting molecule is called a bicarbonate ion. Carbonic acid appears frequently in the natural world. It can be found in sodas, champagne, and blood. The acid even appears in rain.

But like so many things in nature, it’s all about balance.

A week ago, the 2nd March, Patrice Ayme gave me permission to reproduce an essay of his The collapse of the biosphere.  In that essay he wrote,

Besides, it’s not all about “climate change”. Half of the CO2 is presently dissolving in the oceans, so a rise of two degrees Celsius means extremely acid oceans (CO2 turns into carbonic acid after it reacts with water). At the present rate of acidification, marine life will dissolve big time by 2100. That’s how a lot of the oxygen is produced, by photosynthesizing unicellular animals, with acid sensitive skeletons. Atmospheric poisoning deniers do not want just to warm us up.

On that same day of March 2nd, Yves Smith of Naked Capitalism published an item that reinforced what Patrice wrote.  Yves very kindly gave me permission to republish her Post in full, as follows:

Current Rate of Ocean Acidification Worst in 300 Million Years

Science has published a troubling but not entirely surprising article on the fact that the oceans are acidifying at the fastest rate in 300 million years. Actually, it could be the fastest rate over an even longer time period, but we can only go back with any degree of accuracy for 300 million years

We first wrote about this issue in early 2007, and this section, which quoted Stormy from Angry Bear, will help bring readers up to speed:

….there are side effects to our love affair with CO2 that are not often mentioned. In fact, whether the earth cools or warms is absolutely irrelevant to these effects. I repeat: Absolutely irrelevant.

One of the most startling effects is the acidification of the oceans. Since 1750, the oceans have become increasingly acidic. In the oceans, CO2 forms carbonic acid, a serious threat to the base of the food chain, especially on shellfish of all sizes. Carbonic acid dissolves calcium carbonate, an essential component of any life form with an exoskeleton. In short, all life forms with an exoskeleton are threatened: shell fish, an important part of the food chain for many fish; coral reefs, the habitat of many species of fish….

The formation of carbonic acid does not depend upon temperature. Whether the oceans warm or cool is irrelevant. Of concern only is the amount of CO2 that enters the oceans.

Fast forward to today. Consider the scope of the paper in Science, per a very good discussion in ars technica:

A new paper in Science examines the geologic record for context relating to ocean acidification…The research group (twenty-one scientists from nearly as many different universities) reviewed the evidence from past known or suspected intervals of ocean acidification…They find that the current rate of ocean acidification puts us on a track that, if continued, would likely be unprecedented in last 300 million years.

There is an important driver of this process that this overview mentions only in passing further on, and it’s useful to have it in mind when you review the discussion of the historical record:ocean acidification depends primarily on the rate of atmospheric CO2 increases, not the absolute concentration. Look at how attenuated the rate of past CO2 changes was in the past versus the speed now:

The first period the researchers looked at was the end of the last ice age, starting around 18,000 years ago. Over a period of about 6,000 years, atmospheric CO2 levels increased by 30 percent, a change of roughly 75 ppm. (For reference, atmospheric CO2 has gone up by about the same amount over the past 50 years.) Over that 6,000 year time period, surface ocean pH dropped by approximately 0.15 units. That comes out to about 0.002 units per century. Our current rate is over 0.1 units per century—two orders of magnitude greater, which lines up well with a model estimate we covered recently.

The last deglaciation did not trigger a mass extinction, but it did cause changes in some species…

During the Pliocene warm period, about 3 million years ago, atmospheric CO2 was about the same as today, but pH was only 0.06 to 0.11 units lower than preindustrial conditions. This is because the event played out over 320,000 years or so. We see species migration in the fossil record in response to the warming planet, but not ill effects on calcifiers…

Next, the researchers turned their focus to the Paleocene-Eocene Thermal Maximum (or PETM), which occurred 56 million years ago. Global temperature increased about 6°C over 20,000 years due to an abrupt release of carbon to the atmosphere (though this was not as abrupt as current emissions). The PETM saw the largest extinction of deep-sea foraminifera of the last 75 million years, and was one of the four biggest coral reef disasters of the last 300 million years…

The group also examined the several mass extinctions that defined the Mesozoic—the age of dinosaurs. The boundary between the Triassic and Jurassic included a large increase in atmospheric CO2 (adding as much as 1,300 to 2,400 ppm) over a relatively short period of time, perhaps just 20,000 years. The authors write, “A calcification crisis amongst hypercalcifying taxa is inferred for this period, with reefs and scleractinian corals experiencing a near-total collapse.” Again, though, it’s unclear how much of the catastrophe can be blamed on acidification rather than warming.

Finally, we come the big one—The Great Dying. The Permian-Triassic mass extinction (about 252 million years ago) wiped out around 96 percent of marine species. Still, the rate of CO2 released to the atmosphere that drove the dangerous climate change was 10-100 times slower than current emissions…

In the end, the researchers conclude that the PETM, Triassic-Jurassic boundary, and Permian-Triassic boundary are the closest analogs to the modern day, at least as far as acidification is concerned. Due to the poor ocean chemistry data for the latter two, the PETM is the best event for us to compare current conditions. It’s still not perfect—the rate of CO2 increase was slower than today…

The authors conclude, “[T]he current rate of (mainly fossil fuel) CO2 release stands out as capable of driving a combination and magnitude of ocean geochemical changes potentially unparalleled in at least the last ~300 [million years] of Earth history, raising the possibility that we are entering an unknown territory of marine ecosystem change.”

Translation: “We’re probably fucked, but the data is so far outside of historical parameters, we can’t say anything with a high degree of certainty.”

Worth protecting, worth saving, worth caring about!

Reply to a skeptic

“Unless someone like you cares a whole awful lot, Nothing is going to get better. It’s not.”

I came across this wonderful quotation on a blogsite called Wibble!  It was a comment to a post with the compelling title of It is vitally important not to make connections and explains that the quote was made by Dr. Seuss in the film The Lorax.

For me that quotation sums up how I would like to reply to not only my dear friend, Dan Gomez, who is a denialist of anthropogenic climate change, as last Monday’s Post illustrated, but also to skeptics everywhere else.

I should also add the important qualifier that I am neither a scientist nor have any expert skills in the relevant areas.  But, then again, neither does Dan.  He and I are both citizens of Planet Earth with a passion for the truth.

So where to go from here?  There is no question that the Earth’s climate is complex and endeavouring to understand ’cause and effect’ relies heavily on mathematical models.  But many complex aspects of our world are treated similarly, therefore so what!  Dan and I share with millions of others a lack of scientific competence, ergo we have to be rely on the scientific views expressed by those who do have the scientific competencies.

Would one challenge the competence of Scientific American magazine, that in an article on March 18, 2007, (five years ago!) opened thus,

Paris–The signs of global climate change are clear: melting glaciers, earlier blooms and rising temperatures. In fact, 11 of the past 12 years rank among the hottest ever recorded.

and continued later with this, [my emboldening]

For example, after objections by Saudi Arabia and China, the report dropped a sentence stating that the impact of human activity on the earth’s heat budget exceeds that of the sun by fivefold. “The difference is really a factor of 10,” says lead author Piers Forster of the University of Leeds in England: compared with its historical output, the sun currently contributes an extra 0.12 watt of energy for each square meter of the earth’s surface, whereas man-made sources trap an additional 1.6 watts per square meter.

Or what ‘influence’ might be at play when the British newspaper The Guardian reported earlier this year that,

Wall Street Journal rapped over climate change stance

, US environment correspondent

The Wall Street Journal has received a dressing down from a large group of leading scientists for promoting retrograde and out-of-date views on climate change.  In an opinion piece run by the Journal on Wednesday, nearly 40 scientists, including acknowledged climate change experts, took on the paper for publishing an article disputing the evidence on global warming.

The offending article, No Need to Panic About Global Warming, which appeared last week, argued that climate change was a cunning ploy deployed by governments to raise taxes and by non-profit organisations to solicit donations to save the planet.

It was signed by 16 scientists who don’t subscribe to the conventional wisdom that climate change is happening and is largely man-made – but as Wednesday’s letter points out, many of those who signed don’t actually work in climate science.

Later in that article Suzanne writes, referring to the 40 scientists, [again, my emboldening]

The letter goes on to note that some 97% of researchers who actively publish on climate science agree that climate change is real and caused by humans. It concludes: “It would be an act of recklessness for any political leader to disregard the weight of evidence and ignore the enormous risks that climate change clearly poses.”

There’s much, much more evidence that shows that the science is clear – mankind is risking the future viability of this planet for the species homo sapiens and countless other species!

One of the important points made by Dan in that Post last Monday was about the book, written by Senator James Inhofe, The Greatest Hoax.  Dan wrote, “This is all about money and power, not weather.

There are a number of independent websites across the world where one can quickly research the credentials and background by name of any person.  Try Skeptical Science as an example.  A quick enquiry using Senator Inhofe’s name came up with this: Quotes by James Inhofe – Climate Myth/What the Science Says.  Read It!  And read this on the website Think Progress.  There are other websites where one can do that type of research.

In an email just a day ago, Dan wrote, “My message/warning remains the same: “Follow the Money”.  When the “End-of-the-World” is the message, what politician can resist?”  If only it was that easy.

OK, I’m going to start rounding this all off by first asking you to watch this 4-minute video that I came across thanks to Pedantry’s blogsite Wibble.

A link between climate change and Joplin tornadoes? Never!

Next I’m going to repeat something that I have previously mentioned on Learning from Dogs.  There’s a saying in the aviation industry, “If there’s any doubt, there’s no doubt!”  That saying underpins the culture that has turned commercial air transport into one of the safest means of travel in history.

Let’s ponder that idea of doubt.

There is no question that there is a great deal of doubt.  Back in 2010 Gallup Poll reported that “42% of adults worldwide who see global warming as a threat to themselves and their families in 2010 hasn’t budged in the last few years“.

Would you get into a commercial airliner to fly from ‘a’ to ‘b’ if 42% of the passengers saw the flight as a threat to themselves?  No, of course not!

So one certainly wouldn’t fly then if 62% thought it was risky!  From here,

The newest study from the National Survey of American Public Opinion on Climate Change, which is a biannual survey taken since fall 2008 and organized by the Brookings Institute, shows that 62 percent of Americans now believe that man-made climate change is occurring, and 26 percent do not. The others are unsure.

So back to the theme that started this Post.  For the sake of all of us on this planet, for all our children and grandchildren and beyond, we need to start caring deeply about the future, changing our life-styles in as many ways as we can and demanding that our politicians and leaders are similarly committed to the future.

Not because the future is anything like certain – but to reduce the risks of a global catastrophy.  I have a grandson who will be one-year-old on March 21st.  I want to be certain that he has a viable life ahead of him for many, many years.  That means caring ‘a whole awful lot‘, letting hope motivate me to change, and recognising that change is already taking place, as the following trailer so superbly demonstrates.

“Unless someone like you cares a whole awful lot, Nothing is going to get better. It’s not.”

Interlude

Only so much ‘heavy’ stuff that one can take at a time!

Yesterday, I wrote a piece about my dear friend Dan’s skeptic view of man-cause climate change.  Last Friday, I published a guest post from Patrice Ayme under the title of The collapse of the biosphere.  In the last 24 hours I also wrote a long comment to Martin Lack’s latest post, No cause for alarm? – You cannot be serious!  So, don’t know about you, dear reader, but it felt appropriate for today’s Post to be full of fluffy stuff.

First an update on our latest member of our family, Kaysee (although we prefer the spelling Casey!).  Can’t believe that it was only a week ago since we got Casey from the local Humane Society but that’s what it was, Casey joined us on the 28th February.  Here are two photographs of Casey taken last Saturday, four days ago!

H'mm, let me try his lap!
No, this is definately the better one!

So I think one can say that Casey has settled in very well!

Next, Cynthia, the wife of Dan Gomez, emailed me a set of wonderful photographs that had come to her from sister-in-law Suzann.  Here’s a small selection for you to drool over.

Hallo! You're cute!
Love it when the phone is left on 'vibrate'!
Hey Mum, can I have fur as soft as this?
Sorry guys, I can't open the door for you!
Ah, that's perfect! Maybe a tad lower!

Meanwhile tomorrow it’s back to the grind!

A skeptic’s view

Dan Gomez offers up an alternative view.

Many of you read the post I called Please help! that came out exactly a week ago.  If you were one of those readers you will have read how Dan and I go back 33 years.  In many ways we see eye-to-eye but not over mankind’s influence over the climate of our Planet.  To be clear, my own view is that we are very close, if not already past, the point of preventing a massive collapse of the biosphere.  Dan believes that we are living through possibly the biggest hoax in history.

Dan, however, has been willing to provide evidence that supports his view and has given me permission to reproduce some of his emails to me.  That’s generous of him – thanks Dan.

Let’s start with Dan’s reply to my offer to buy him the book Betrayal of Science and Reason by Paul & Anne Ehrlich.  This is what Dan sent to me,

PH – I guess I could write all day and provide numerous scientific papers and positioning that would repudiate a lot of the popular press on “Global Warming” or “Climate Change”, if that is more PC.  Read a little from the good Senator below and then I’ll buy you HIS book.

This is all about money and power, not weather. As the Senator points out, when he saw that the “Cap and Trade” bill was shot down, he stopped commenting. Then, more and more regulation from the UN and EPA Agency provoked this new book.

Once again, the science is at best moot and at worst fraudulent. Each of us must make up his own mind. Global climate cooling or heating will continue operating under geological time rules and, oh yeah, the Sun, Oceans and Regional Oscillations contribute a little.

As long as world governments don’t take public money or redistribute public money for their own “climate control” self-interests, I don’t really care. If there was no public money at stake, there would be no controversy.

People will continue to build houses below sea level in New Orleans. Another, bigger hurricane will flood them out again. Apparently, we can’t even stop this kind of nonsense through more legislation and then expensive emergency re-routing of public funds. This is part of the reason that the public sector is broke.

If private agencies wish to donate money to stop the rising seas or just support related studies, tant mieux. Just don’t add yet another set of agencies and regulations as another layer of big government. This only results in an ever higher tax structure and declining standards of living.

Book Description

Publication Date: February 28, 2012

Americans are over-regulated and over-taxed. When regulation escalates, the result is an increase in regulators. In other words, bigger government is required to enforce the greater degree of regulation. Bigger government means bigger budgets and higher taxes. “More” simply doesn’t mean “better.” A perfect example is the entire global warming, climate-change issue, which is an effort to dramatically and hugely increase regulation of each of our lives and business, and to raise our cost of living and taxes. In The Greatest Hoax, Senator James Inhofe will reveal the reasons behind those perpetuating the Hoax of global warming, who is benefitting from the general acceptance of the Hoax and why the premise statements are blatantly and categorically false.

In another couple of emails, Dan wrote,

There are two questions to answer: Whose science do you want to believe and who profits? My source of direction stems from a natural skepticism of big science when big money is involved. One of the definitions of science is that it is never completely understood and new discoveries as well as new methods of collecting data are ever changing. As we know, new evidence pops up everyday. So, to assume that “my science or your science” is irrefutable relevant to global warming, is not “good science”. Taking billions of global dollars out of private enterprise as well as higher public sector tax in order to “change the world- maybe” is irresponsible and dangerous.

Oh yeah, and I forgot, the world’s broke. Ask a Greek plumber or, for that matter, a Greek apparatchik, where global warming fits into his budget decisions……?

Then Dan wrote in another email,

 Emotionalism aside, I can’t argue the science issues except by contributing relevant articles by other scientists with opposing views. There are many.  I can comment on the political power and self-interest motivations of many proponents and that’s always fun……

Finally, Dan sent me the full copy of a recent article published by Roy Spencer, Ph. D. called Ten Years after The Warming.  He introduced it thus,

Before spending trillions that the world does not have, let’s see if we can get the conversation a little more firmed up…..  We need to really find out how sensitive the atmosphere, lithosphere and hydrosphere really are –  without assumptions.  Pretty hard thing to do even with advanced mainframes, GIGO…..

and then offered the article,

Ten Years After the Warming

February 26th, 2012 by Roy W. Spencer, Ph. D.

The version of global warming theory being pushed by the IPCC is that anthropogenic emissions of greenhouse gases are causing a radiative energy imbalance of the climate system, leading to warming.

The radiative forcing history being used in the latest IPCC climate models looks something like the following, with red areas representing times when the climate system’s “stove is turned up”, that is, with heat accumulating in the system.

(Actually, the correct analogy would be that the stove setting remains the same, but the lid partially covering the pot is covering it a little more over time…but that’s too hard to explain.)

As can be seen, in the last 10 years the estimated forcing has been the strongest. Yet, most if not all temperature datasets show little or no global-average warming recently, either in the atmosphere, at the surface, or in the upper 700 meters of the ocean. For example, here are the tropospheric temperatures up though a few days ago:

So what is happening? You cannot simply say a lack of warming in 10 years is not that unusual, and that there have been previous 10-year periods without warming, too. No, we are supposedly in uncharted territory with a maximum in radiative forcing of the climate system. One cannot compare on an equal basis the last 10 years with any previous decades without warming.

There are 5 possibilities for the recent cessation of warming which are most discussed:

1) cooling from anthropogenic aerosols has been cancelling out warming from more greenhouse gases

2) natural cooling from internal climate fluctuations or the sun is cancelling out the GHG warming

3) increased ocean mixing is causing the extra energy to be distributed into the deep ocean

4) the temperature ’sensitivity’ of the climate system is not as large as the IPCC assumes.

5) there is something fundamentally wrong with the GHG warming theoryitself

Of course, some combination of the above 5 explanations is also possible.

The 1st possibility (aerosol cooling is cancelling out GHG forcing) is one of the more popular explanations with the climate modelers, and especially with NASA’s James Hansen. The uncertain strength (and even sign) of aerosol forcing allows the climate modelers to use aerosols as a tuning knob (aka fudge factor) in making their models produce warming more-or-less consistent with past observations. Using an assumed large aerosol cooling to cancel out the GHG warming allows the modelers to retain high climate sensitivity, and thus the fear of strong future warming if those aerosols ever dissipate.

The 2nd possibility (natural cooling) is a much less desirable explanation for the IPCC crowd because it opens the door to Mother Nature having as much or more influence on the climate system than do humans. We can’t have that, you know. Then you would have to consider the possibility that most of the warming in the last 50 years was natural, too. Goodbye, AGW funding.

The 3rd possibility (increased ocean mixing) is one of the more legitimate possibilities, at least theoretically. It’s popular with NCAR’s Kevin Trenberth. But one would need more observational evidence this is happening before embracing the idea. Unfortunately, how vertical mixing in the ocean naturally varies over time is poorly understood; the different IPCC models have widely varying strengths of mixing, and so ocean mixing is a huge wild card in the global warming debate, as is aerosol cooling. I believe much of past climate change on time scales of decades to many centuries might be due to such variations in ocean mixing, along with their likely influence on global cloud cover changing the amount of solar input into the climate system.

The 4th possibility (the climate system is relatively insensitive to forcing) is the top contender in the opinion of myself, Dick Lindzen, and a few other climate researchers who work in this field.

The 5th possibility (increasing GHGs don’t really cause warming) is total anathema to the IPCC. Without GHG warming, the whole AGW movement collapses. This kind of scientific finding would normally be Nobel Prize territory…except that the Nobel Prize has become more of a socio-political award in recent years, with only politically correct recipients. The self-flagellating elites don’t like the idea humans might not be destroying the Earth.

The longer we go without significant warming, the more obvious it will become that there is something seriously wrong with current AGW theory. I don’t think there is a certain number of years – 5, 10, 20, etc. – which will disprove the science of AGW….unless the climate system cools for the next 10 years. Eek! But I personally doubt that will happen.

As long as strong warming does not resume, the heat-hiding-in-the-deep-ocean explanation will provide refuge for many years to come, and will be difficult to convincingly rule out as an explanation since it takes so long for the deep ocean to warm by even a tiny amount.

Instead, there probably will be a tipping point (sooner than later) in popular perception when the public and Congress decide the jig is up, and they are no longer interested in hearing how we ‘might’ be headed for Armageddon.

The public already knows how awful scientists are at forecasting the future…especially a future of doom, which curiously seems to be the only future scientists know how to predict.

Now the challenge in this Post is not to make it so long that it becomes tiresome on the eyes, irrespective of the content.

So I’m going to leave it at this point and, perhaps, next time include some of Dan’s other points and comments in the light of how readers respond to this Post.

The collapse of the biosphere.

Further to my Please help! post.

On Monday of this week, I posted an item called Please help!  It was to demonstrate how easily two people, with a long-standing friendship, both interested in the world around them, can differ over something so fundamental as man’s affect on our Planet.

I hoped that it would attract those who see things more clearly, and I was not mistaken.  Not only did the item receive 1,334 readings on that day, there were a number of focused comments, plus emails to me personally.  One of those comments was from Patrice Ayme, a long-standing friend of this Blog, who referred me to an article he had written in 2009, called BIOSPHERE COLLAPSE.  I gratefully republish that article with the written permission of Patrice.

BIOSPHERE COLLAPSE, not “Climate Change”.

by Patrice Ayme.

It is a curious thing to observe how far some humans will go to make themselves the center of attention. Maybe it’s out of cowardice. After all, to become the center of something, however illusory, however silly, allows one to forget the fragility of the human condition.

A handful of top notch elite scientists can be found, who are among those who are skeptical about the fact that burning the fossil fuel accumulated in the last 400 million years is causing a dangerous warming of the climate. Those who belong to the elite are generally not climate scientists, but, unsurprisingly geologists or geophysicists (that means, paid by the burning of fossil fuels).

Moreover, when one looks at their arguments, or even their graphs, one generally find obvious bias. I have explained before that denial is big business, and that the sun itself has conspired with the giant fossil fuel business (the ultimate conspiracy theory!)

But this streak of solar cooling is not enough for the partisans of atmospheric poisoning. It seems as if they were hell bound not only to poison the air and the oceans, but reason itself. (I have explained in other essays that reason itself is the preferred target of the plutocrats and their agents.)

A preferred trick of those tricksters is to cut the graph depicting the concentration of CO2 at, say, 360 parts per million (ppm), when we are actually at 390 ppm! This has the undeniable advantage of masking the exponential growth of atmospheric CO2 in the last few years…

image

What we see in this graph is a basically flat line, followed by an exponential (the famous “hockey stick”, as a climate scientist dubbed it).

From studying ocean sea shells, we now know that the CO2 concentration did not exceed 300 ppm for the last 25 million years. That means that the basically flat line in the graph above extends considerably to the left. The basically flat line actually extends 2 kilometers to the left, at the scale of the graph above. Yes, more than a mile!

So there is no doubt that the recent CO2 exponential climb is man-made, and tied up to industry.

A related trick of the deniers is to “forget” that man has generated a lot of other gases than CO2. Those artifical, man-made gases can be up to 10,000 times better than CO2 at blocking infrared light.

A greenhouse consists of allowing visible light in, while blocking the exit of the light that heat makes, the infrared light. Three large greenhouses are Mars, Earth and Venus. All planets are greenhouses, and earth-like planets in other solar systems will have water, thus water vapor and CO2, two most powerful and natural greenhouse gases: these gases allow light in, but tend to block infrared.

Thus the heat gets trapped close to the ground, and the high atmosphere, now less warmed by infrared light on its way to space, cools down. Some ignorant fools have heard of that cooling, and screamed that it proved that there was no greenhouse, because a cooling has been demonstrated. Whereas, in truth, that high altitude cooling is expected, and proves the exact opposite, namely a greenhouse next to the ground!

When one is considering the man-made greenhouse, one has therefore to also include these exotic industrial gases and evaluate their contribution to the greenhouse. For example, the Greenhouse Warming Potential (GWP) for methane over 100 years is 25 and for nitrous oxide it is 298. This means that emissions of 1 million metric tons of methane and nitrous oxide respectively warm up the lower atmosphere as much as the emissions of 25 millions and 298 millions metric tons of carbon dioxide, respectively, over the following century.

Perfluorocarbons (CFCs) are the worst. They are used in refrigeration. The most frequent is tetrafluoromethane. Its GWP is 6,500 times that of CO2. The GWP of hexafluoroethane is 9,200 times that of carbon dioxide. Over ten years, the GWP of methane is higher than what it is over a century, because methane oxydizes quickly. Over ten years the GWP of methane is 100 times that of CO2. This means that a “methane burp“  would have a tremendous warming effect. There are reasons to believe that such “methane burps” have happened, and could happen again. They are catatastrophically violent events, complete with giant tsunamis, I know you wanted to know…

In any case we are around 450 ppm in CO2 equivalent (the exact number is fiercely debated, and irrelevant, because the yearly augmentation is so fast).  We started from 280 ppm of CO2 equivalent in 1850 and at this rate we will pass a DOUBLING within twenty years.

Recent research on marine fossils has allowed us to find out the CO2 concentration over the last 25 million years: it never exceeded 300 ppm durably. (There were short spikes due to occasional major volcanic activity, but that’s always accompanied by marked and brutal drops in temperature, so Antarctic records show the two contrary effects wash each other out!)

I would go as far as saying that many papers in Nature and Science, when they deal about the climate, systematically underemphasize the planetary danger we seem to be getting in. Typically the authors’ research reveals an ominous evolution, but, then, rather meek conclusions are modestly drawn. There is no doubt an implicit pressure from the powers that be to not disrupt big business as usual, and climate scientists prefer to not bite the hand that feeds them (considering where the money, hence power, goes, that would be Goldman Sachs, or, at least, the fossil fuel/pollution establishment, which is somewhere near Goldman Sachs in the Pantheon that rules over us).

The IPCC, the world panel on “Climate Change” is the number one exhibit of meekness, and lack of common sense as far as viewing a “small” global temperature rise as tolerable. In its computations, the IPCC has refused to enter the melting of the polar ice shields, and the possibility of methane clathrate  eruptions. Yet, it is known, from computing the sea level rise, and its acceleration, that the giant ice shields at the poles are melting.

It is also known that the methane (CH4) density in the atmosphere has doubled, or, maybe, quadrupled. During the last significant warm-up, methane eruption occured, causing a giant tsunami in the North Atlantic (in places, water went an incredible 80 kilometers inland!) The IPCC ignores all this superbly, preferring naively to stick to proven, observed and incontrovertible facts, and scrupulously rejecting inchoating, or probable events.

The IPCC claims to believe that limiting the global temperature rise at 2 degrees Celsius would be fine. Instead, it would be a dangerous stupidity to approach a two-degree Celsius of global temperature rise (yes, I thought carefully before using the word “stupidity“: all alternatives were found wanting).

Indeed the whole problem is not to warm up the poles too much. The global temperature rise is irrelevant. Two degrees more in Texas or Australia would just lead the offending natives to crank the air conditioning higher, and pour more prehistoric aquifer water on their greens.

Whereas the frozen poles constitute the planet’s air conditioning system. The frozen poles reflect light out into space, and make the atmosphere in a Carnot engine, with a warm source (the tropics) and a cold sink (the frozen poles). Heat is transported from warm to cold, from tropics to poles, by enormous oceanic currents, such as the Gulf Stream. Melt the poles, remove the heat reflectors, and shut down the currents.

But most of the warming, so far, is at the poles, and it has already reached nearly 5 degrees Celsius in parts (the Antarctica peninsula, for example). Yet, the global temperature rise, so far, is roughly ONLY one tenth of that. Scaling up, on present evidence, a global planetary rise of two degrees Celsius may mean a rise of twenty degrees Celsius in many glaciated polar areas (yes, a rise of 40 degrees Fahrenheit). So the poles would melt, and the Earth would lose its reflectors. Tipping points would tip, and things would get worse from there. Oceanic currents would stop. Europe would freeze in winter. Golbal temperatures would shoot up. Oxygen would disappear from huge parts of the tropical oceans, which would die. (Several of the preliminaries of these effects are tentatively observed.)

Many people reading this will scoff and say that this will not happen, because it did not happen before. Paleontologically, this is not true.  Although there was no human industry to start a CO2 bubble, they have happened before (they can be generated by continental drift or super giant volcanic eruptions known as “supertraps”).

When dinosaurs flourished, the poles were warm. Dinosaurs were roaming the forests of Antarctica. Crocodiles terrorized Northern Greenland. However, the world had dozens of millions of years to adapt. Polar dinosaurs saw with the lights of the stars for months on end. Right now, we are going to hit the biosphere with the heat shock from hell.

Besides, it’s not all about “climate change”. Half of the CO2 is presently dissolving in the oceans, so a rise of two degrees Celsius means extremely acid oceans (CO2 turns into carbonic acid after it reacts with water). At the present rate of acidification, marine life will dissolve big time by 2100. That’s how a lot of the oxygen is produced, by photosynthesizing unicellular animals, with acid sensitive skeletons. Atmospheric poisoning deniers do not want just to warm us up.

Ah, also, just a reminder, some gigantic, and deep, parts of the oceans got too warm to contain enough oxygen to support life, and they have already died.

And yes, the oceans are rising, and the icecaps are melting, both in Greenland, and Antarctica.  The rise of sea level is itself augmenting at the rate of 5% a year (as many of the facts in this post, published in summer or fall of 2009). It’s an exponential!

When something augments at a rate proportional to its own value, it’s an exponential. The exponential is the most important function in analysis, if not mathematics. The exponential augments extremely fast, because the bigger it is, the faster it becomes bigger. Peons who know the exponential not, have no idea the danger we are in! They have no mathematical understanding of the danger we are in. They need to take those mathematic classes they never took, to realize how immoral their ignorance is.

The more fossil fuels burned, the more hot air, the less oxygen. But not to worry!  American politicians will be pleased to inform you that their super private, super bank, the one which advises the White House always, and pays bonuses with taxpayer money, Goldman Sachs, will make a future oxygen market, and will sell it short. Trust American capitalism, White House style, to adapt. Down to the last gulp of air.

On a slightly more serious note, the expression “climate change” is thus a misnomer.

In truth, we are facing a man-made collapse of the biosphere, just because full grown men want to keep on playing with fire. There ought to be an IPCB: Intergovernmental Panel on the Collapse of the Biosphere.

Atmospheric poisoning deniers want to heat us up in acid, while cutting our air supply. By 2100 CE. Of course, when that apocalypse has become the future no one can deny, there will be only one solution: nuke the coal plants. More seriously, Asia plans an enormous augmentation of its CO2 production, and that may very well become a casus belli, when the runaway exponential nature of the man-made greenhouse becomes blatant.

Technical annex 1: To calculate the radiative forcing for a 1998 gas mixture, the IPCC in 2001 gave the radiative forcing (relative to 1750 CE) of various gases as: CO2=1.46 (corresponding to a concentration of 365 ppm), CH4=0.48, N2O=0.15 and other minor gases =0.01 W/m2. The sum of these is 2.10 W/m2. One obtains COequivalent = 412 ppm. That was in 2001, we are in 2010 (about). CO2 concentration is now 290 ppm, which means that CO2 equivalent is above 440 ppm.

Technical annex 2: Quoting straight from Science:

“Climate Change: Fixing a Critical Climate Accounting Error.

The accounting now used for assessing compliance with carbonlimits in the Kyoto Protocol and in climate legislation contains a far-reaching but fixable flaw that will severely undermine greenhouse gas reduction goals (1). It does not count CO2 emittedfrom tailpipes and smokestacks when bioenergy is being used,but it also does not count changes in emissions from land use when biomass for energy is harvested or grown. This accounting erroneously treats all bioenergy as carbon neutral regardlessof the source of the biomass, which may cause large differences in net emissions. For example, the clearing of long-established forests to burn wood or to grow energy crops is counted as a 100% reduction in energy emissions despite causing large releases of carbon.”

[Science 23 October 2009: Vol. 326. no. 5952, pp. 527 – 528.]

It is hard to believe that errors of such magnitude, committed by scientists (and implemented by the European Union and the US Congress) are not deliberate.

A plea to those who understand climate science so much better than I do!

Background to this Post.

Among my friends, two go way back.  One of them, Dan Gomez, a lively, ebullient Californian, was indirectly responsible for me and Jean meeting in Mexico back on December 17th, 2007.  I first met Dan at a dealers’ conference in Boston way back in the early days of Commodore Computers.  That was the Spring of 1979 and I had flown to Boston as the owner of the 8th Commodore Computer dealership to be appointed in the UK, based in Colchester, Essex.  Later, I became the global distributor of an English word processing program known as Wordcraft, written by Pete Dowson in the UK, and appointed Dan as my US West Coast Wordcraft distributor.  It gave me a wonderful reason to come out to Southern California several times a year; on business, of course!

Dan and I therefore go back 33 years!  Dan’s sister Suzann has a house down in San Carlos, Mexico.  Suzann invited me out to Mexico for Christmas 2007 which is where I first met Jean and, bingo, Jean and I then fell in love with each other!  How life flows!  (Two years ago yesterday, Jean and I moved into our house in Payson with our, then, 13 dogs and 6 cats!)

Paul & Dan Jan. 15th 2008

OK, to the Post!

Dan has been a climate change skeptic, as in caused by man, for many years.  Regular readers of Learning from Dogs will know I see things very differently.  But Dan and I agree fundamentally on getting to the truth.  This Blog proudly claims to seek “The underlying theme of Learning from Dogs is about truth, integrity, honesty and trust in every way.”

So when the other day Dan sent me a number of links supporting his view that “My point remains that climate change is an enormous, complex process that no computer model is going to predict and no human activity modify significantly. Big money is now at stake here and as the article shows, even trusted scientists will produce fraudulent information to further their goals as well as fill politician’s coffers.” I found my faith in my own views slighted dented.  Dan is a smart guy, a good thinker and not beholden to any firm or organisation with a vested interest in denying anthropogenic global warming.

Here are some of the items that Dan referred to,

IPCC Scientist Admits Fake Data Used To Pressure World Leaders

A scientist responsible for a key 2007 United Nations Intergovernmental Panel on Climate Change report warning Himalayan glaciers would be completely melted by 2035 has admitted that the claim was made to put political pressure on world leaders.

Such was revealed by the British Daily Mail Sunday in an article destined to further reduce the credibility of the world’s so-called leading authority on manmade global warming.

As NewsBusters reported Saturday, the IPCC acknowledged earlier this week that its claim concerning these glaciers was based on junk science.

Oregon Chapter American Meteorological Society

Anthropogenic (Human Caused) Global Warming – Is This The Greatest Scientific Myth of our Generation?”
January 25th, 2012, Portland, Oregon

First Speaker – Gordon Fulks, PhD Physics, University of Chicago

[Extract]

Dr. Fulks said: “My thesis tonight is simple: virtually ALL of what climate alarmists put forth as science is not. Some is half correct, some is incorrect, and too much is just plain nonsense or worse.”

This led him into what he called “one of the central problems with Anthropogenic Global Warming,” “the integrity of the data.” He discussed a variety of temperature data from land surface data that shows various manipulations and biases to the best global data from NASA satellites to the excellent ice core temperature proxies going back 450,000 years.

Second Speaker – Chuck Wiese, Meteorologist – Oregon State University

[Extract]

Mr. Wiese finished his presentation with the following conclusions:

1. There is nothing in the REAL atmospheric record that supports the recent temperature rise of the last century to carbon dioxide induced anthropogenic warming.

2. The tropospheric water vapor optical depth is remarkably stable but has declined recently over the last 70 years of record as carbon dioxide rose substantially in the atmosphere during the same period. This is a consistent outcome as expected by the first principle founding physics and inconsistent with atmospheric climate models.

3. Without water vapor acting as a positive feedback ( growth pattern ) to increasing carbon dioxide concentrations, the projected radiative forcing on the earth’s surface is but a grossly exaggerated calculation of what the earth’s temperature will actually do in response to carbon dioxide.

4. The earth’s “greenhouse effect” is NOT controlled by atmospheric carbon dioxide. It is modulated and governed by atmospheric water vapor and clouds, where the warming modulation is controlled by the amount of vapor and optical depth. Clouds with the hydrological cycle act to trim out water vapor into a hydrostatic, convective equilibrium. The stable atmospheric optical depth likes the earth mean temperature of 59 deg F without further solar or planetary modulation.

5. The Anthropogenic warming hypothesis by atmospheric CO2 is falsified by the real record and radiation physics.

Third Speaker – George Taylor, former Oregon State Climatologist

[Extract]

His presentation finished with his conclusions:

1. Human activities DO affect climate, in a variety of ways. Greenhouse gases are just one parameter.

2. Natural variations affect climate. I believe that they have been more significant influences on climate because they do a much better job of explaining observed variations.

3. Effects of future changes in CO2 are likely to be modest and manageable.

4. Many aspects of climate remain poorly understood.

The full transcripts and supporting materials may be seen here.

Then, in stark contrast, this week’s edition of The Economist has a leader about the problem of overfishing. “Of all the sea’s many problems, overfishing should be the most fixable. ”  What jumped off the page at me was how that leader article started,

ACIDIFICATION, warming, the destruction of coral reefs: the biggest problems facing the sea are as vast, deep and seemingly intractable as the oceans themselves. So long as the world fails to cut its emissions of greenhouse gases, cause of the global warming behind these troubles, they will grow.

So a newspaper of the standing of The Economist is clear, “So long as the world fails to cut its emissions of greenhouse gases, cause of the global warming behind these troubles

So if, dear reader, you can offer good supporting evidence as to why the Oregon Chapter of the American Meteorological Society seems to contradict what so many now believe, that mankind is changing the Earth’s climate, please comment or, better still, consider writing a guest post.

Thank you!

A review of Michael Mann’s new book The Hockey Stick and the Climate Wars: Dispatches from the Front Lines.

I’m republishing in full a recent Post on Kate’s fabulous blogsite Climate Change.  As a degree student, Kate is a fantastic representative of the generation that is going to have to deal in full with all the crap that my generation (born 1944) has brought about!  Learn more about her here.  Anything that can spread the word to those, especially in my age group, that are climate change denialists is no bad thing.

The Hockey Stick and the Climate Wars

February 22, 2012 by climatesight

Available from Columbia Press

Throughout all the years of public disputes about climate change, arguably no scientist has taken as much flak as Dr. Michael Mann. This mild-mannered paleoclimatologist is frequently accused of fraud, incompetence, scientific malpractice, Communism, and orchestrating a New World Order. These charges have been proven baseless time and time again, but the accusations continue. Dr. Mann’s research on climate change is inconvenient for those who wish to deny that current global temperatures are unusual, so he has become the bulls-eye target in a fierce game of “shoot the messenger”. In “The Hockey Stick and the Climate Wars: Dispatches from the Front Lines”, a memoir of his experiences, Michael Mann finally speaks out.

The story begins quite harmlessly: an account of how he became a scientist, from childhood curiosity to graduate work in theoretical physics to choosing climate science on a whim out of the university course calendar. For those who have followed Dr. Mann’s research over the years, there is some great backstory – how he met his coauthors Ray Bradley and Malcolm Hughes, the formation of the IPCC TAR chapter about paleoclimate, and how the RealClimate blog operates. This book also filled in some more technical gaps in my understanding with a reasonably accessible explanation of principal component ananlysis, a summary of millennial paleoclimate research before 1998, and an explanation of exactly how Mann, Bradley and Hughes’ 2008 paper built on their previous work.

Dr. Mann’s 1998 paper – the “hockey stick” – was a breakthrough because it was the first millennial reconstruction of temperature that had global coverage and an annual resolution. He considered the recent dramatic rise in temperatures to be the least interesting part of their work, because it was already known from instrumental data, but that part of the paper got the most public attention.

It seems odd for a scientist to downplay the importance of his own work, but that’s what Dr. Mann does: he stresses that, without the hockey stick, the case for climate change wouldn’t be any weaker. Unfortunately, his work was overemphasized on all sides. It was never his idea to display the hockey stick graph so prominently in the IPCC TAR, or for activists to publicize his results the way they did. Soon the hockey stick became the holy grail of graphs for contrarians to destroy. As Ben Santer says, “There are people who believe that if they can bring down Mike Mann, they can bring down the IPCC,” and the entire field of climate science as a result.

Michael Mann is an eloquent writer, and does a fabulous job of building up tension. Most readers will know that he was the target of countless attacks from climate change deniers, but he withholds these experiences until halfway through the book, choosing instead to present more context to the story. The narrative keeps you on your toes, though, with frequent allusions to future events.

Then, when the full story comes out, it hits hard. Death threats, and a letter full of suspicious white powder. Lobby groups organizing student rallies against Mann on his own campus, and publishing daily attack ads in the campus newspaper. Discovering that his photo was posted as a “target” on a neo-Nazi website that insisted climate change was a Jewish conspiracy. A state politician from the education committee threatening to cut off funding to the entire university until they fired Mann.

Throughout these attacks, Dr. Mann consistently found trails to the energy industry-funded Scaife Foundation. However, I think he needs to be a bit more careful when he talks about the links between oil companies and climate change denial – the relationship is well-known, but it’s easy to come off sounding like a conspiracy theorist. Naomi Oreskes does a better job of communicating this area, in my opinion.

Despite his experiences, Michael Mann seems optimistic, and manages to end the book on a hopeful note about improvements in climate science communication. He is remarkably well-adjusted to the attacks against him, and seems willing to sacrifice his reputation for the greater good. “I can continue to live with the cynical assaults against my integrity and character by the corporate-funded denial machine,” he writes. “What I could not live with is knowing that I stood by silently as my fellow human beings, confused and misled by industry-funded propaganda, were unwittingly led down a tragic path that would mortgage future generations.”

“The Hockey Stick and the Climate Wars” leaves me with a tremendous empathy for Dr. Mann and all that he has gone through, as well as a far better understanding of the shouting match that dominates certain areas of the Internet and the media. It is among the best-written books on climate science I have read, and I would highly recommend it to all scientists and science enthusiasts.

“The Hockey Stick and the Climate Wars” will be released on March 6th, and the Kindle version is already available.

The coming new year!

Be warned, one of my more reflective muses!

Tomorrow is the last day of the year 2011.

For reasons that I am not clear about, there is a mood of pessimism about my person.  Whether it is the scale of global issues that I see ahead that drags me down, whether the year of an American Presidential election will remind me of the loss of reason that afflicts so many modern democracies, whether the messages in Kunstler’s book The Long Emergency still resonate in my mind well, who knows?

But when one does look at the broader picture of modern society, there is much that troubles.

So forgive me if I provide a couple of examples of these troubles.  I do so on the grounds of communication – the more that understand the risks ahead of us, the more likely we, as in the peoples of this planet, will say to our leaders, “Enough of this!  For the sake of my children, my grandchildren and all of humanity we have to change our priorities, and soon!”

Here’s my first example.

The US National Resources Defense Council recently published an item about severe weather including an interactive Extreme Weather Map, introduced thus,

Climate change increases the risk of record-breaking extreme weather events that threaten communities across the country. In 2011, there were at least 2,941 monthly weather records broken by extreme events that struck communities in the US.

That was backed up by an article on the Onearth website that opened,

By many measures, 2011 was the most extreme weather year for the United States since reliable record-keeping began in the 19th century — and the costs have been enormous. According to the National Oceanic and Atmospheric Administration, 2011 set a record for the most billion-dollar disasters in a single year. There were 12, breaking the old record of nine set in 2009. The aggregate damage from these 12 events totals at least $52 billion, NOAA found.

And that just for the USA.  But will climate change be the Number One political issue in 2012?  And if not in 2012, when will it be?

Let me move on to my second example, very different from the one above but, in a sense, just as scary.  This is an interview that was in a recent article on the Food Freedom website ( brilliant website, by the way).  Dr. Joseph Mercola, the leading natural health practitioner, interviews Dr. Don M. Huber, one of the senior scientists in the U.S about the area of science that relates to genetically modified organisms (GMO). Here’s an extract from the article on Food Freedom,

Toxic botulism in animals linked to RoundUp

Dr Mercola recently interviewed Dr Don Huber, whose letter to the USDA warning that Monsanto’s RoundUp, a broad-spectrum “herbicide” that has been linked with spontaneous abortion in animals, continues to be ignored by food and environmental safety authorities. In this important hour-long discussion, Huber, a plant pathologist for over 50 years, explains how RoundUp is destroying our healthy soils by killing needed microorganisms.

Not only did his team discover a new soil pathogen, but he reports that animals are coming down with over 40 new diseases, like toxic botulism. Huber explains that before the widespread use of herbicides, pesticides and genetically modified food and feed, natural probiota would have kept Clostridium botulinum in check

The video, below, of the interview is included in the article.  Please don’t be put off by the length, the material covered is riveting and critical to our general knowledge about the threats to our society.

So that’s enough from me for one day!  On Monday, I shall include another video relating to the RoundUp issue that reveals, both directly and metaphorically, how the only solution to pessimism is to embrace the need to make change happen.  Be inspired by this poem by Sam Keen, included in the latest Sabbath Moment from Terry Hershey,

I Want to Surrender

God, I want to surrender
to the rhythm of music and sea,
to the seasons of ebb and flow,
to the tidal surge of love.

I am tired of being hard,
tight, controlled,
tensed against tenderness,
afraid of softness.
I am tired of directing my world,
making, doing, shaping.

Tension is ecstasy in chains.
The muscles are tightened to prevent trembling.
Nerves strain to prevent trust,
hope, relaxation….

Surrender is a risk no sane man may take.
Sanity never surrendered
is a burden no man may carry.

God give me madness
that does not destroy
wisdom,
responsibility,
love.

Sam Keen

The Long Emergency, part two.

The concluding extract from James Kunstler’s powerful book.

Last Friday, I published the first part of the extract that so powerfully articulated the madness of present global policies (especially US policies) with regard to oil.  Let me continue.

The first part finished thus, “Yet, I was not soothed by these thoughts, nor by the free eats, and even the liquor failed to lift me up because I couldn’t shake the recognition that in the short term we are in pretty serious trouble, too.”

There is near unanimity among the scientific community that global warming is happening.  There is also a definite consensus emerging that the term “climate change” may be more accurate than “global warming” to describe what we are in for.  The mean temperature of the planet is going up.  The trend is unmistakable.  Average global land temperature was 46.90 degrees Fahrenheit [Ed. 8.278 °C.] when modern measurements began and had reached 49.20 degrees F [Ed. 9.556 °C.] in 2003.  The rate of change has also increased steadily.  The total increase of 2.30 degrees might seem trivial, but has tremendous implications.  And the rise in temperature happens to correlate exactly with the upward scale of fossil fuel use since the mid-nineteenth century.

It may not matter anymore whether global warming is or is not a by-product of human activity, or if it just represents the dynamic disequilibrium of what we call “nature.”  But it happens to coincide with our imminent descent down the slippery slope of oil and gas depletion, so that all the potential discontinuities of that epochal circumstance will be amplified, ramified, reinforced, and torqued by climate change.  If global warming is a result of human activity, fossil fuel-based industrialism in particular, then it seems to me the prospects are poor that the human race will be able to do anything about it, because the journey down the oil depletion arc will be much more disorderly than the journey up was.  The disruptions and hardships of decelerating industrialism will destabilize governments and societies to the degree that concerted international action – such as the Kyoto protocols or anything like it – will never be carried out.  In the chaotic world of diminishing and contested energy resources, there will simply be a mad scramble to use up whatever fossil fuels people can manage to lay their hands on.  The very idea idea that we possess any control over the process seems to me further evidence of the delusion gripping our late-industrial culture – the fatuous certainty that technology will save us from the diminishing returns of technology.

So for the purposes of this book, the relevant question concerning global warming and climate change is not whether human beings caused  it or whether we will come up with some snazzy means to arrest it, but simply what the effects are likely to be and what they signify about the way we will live later on this century.

This extract from the book was published in 2005, although there is an Afterword included that was published in 2009.  So to bring things more up to date, here’s a video of James Kunstler speaking about peak oil just about a year ago.

In this fourth video in the series “Peak Oil and a Changing Climate” from The Nation magazine and On The Earth Productions, James Howard Kunstler discusses how finance and energy are running neck and neck to fuel the end of advanced industrial civilization.
