$this->bbcode_second_pass_quote('Artanis568', 'W')e already are. Russia and many European countries now have negative population growth rates, and I believe the US would if not for immigration.


Western population declines have been due solely to the allometry of human fertility and energy use. As energy use per capita declines, population birthrates will rise.

$this->bbcode_second_pass_quote('Artanis568', '
')"2. Rapidly change our diets in the first world to primarily vegetarian, and live much simpler (material and energy consumption wise)."

Have you ever actually succeeded in convincing someone to do this? It would be well-nigh impossible for most of us to change our lives drastically without sufficient impetus (nuclear war, depression, etc.)


People change their diet for the wildest reasons right now. To answer your question, I've done it several times.


$this->bbcode_second_pass_quote('Artanis568', '
') There were certainly enough people who lost everything to start a violent uprising, but they didn't.


This is an obvious association fallacy. Not all people in dire straits behave the same way.

$this->bbcode_second_pass_quote('Artanis568', '
')"In 1989, I concluded that the life-expectancy of Industrial Civilization is horridly short. This hypothesis"

Okay, right away we have a contradiction. He concludes that Olduvai is correct, yet he describes it as a "hypothesis", a coherent body of logic that hasn't been tested. How you can conclude that something is correct without bothering to test it is beyond me.


We don't have a second Earth to run tests on to get conclusive proof with, so we will have to wait to find out. He obviously means that he created a hypothesis and tracked the variables and it seems likely to him that it will be proven correct with time. He isn't using conclusion in the strict logical sense but in the general sense of "I created a theory that so far fits the data and I feel somewhat confident in predicting the future with this theory." Please don't equivocate.

$this->bbcode_second_pass_quote('Artanis568', '"')The broad sweep of human history can be divided... and continuing deterioration of the natural environment."

Blatant assertion, with no evidence. He might as well proclaim that there's an invisible teacup in orbit around Pluto.


It is a well known fact that we are in the greatest species die off since the fall of the dinosaurs. He's not presenting an ecology paper, so I think he gets some wiggle room here.

$this->bbcode_second_pass_quote('Artanis568', 'E')xcept that this "Olduvai signature" doesn't just fit the Olduvai model, it fits dozens of other models as well, with no way to distinguish between them. As an example, suppose I list all the odd numbers: 1, 3, 5, 7... Hey, these numbers are prime! I can therefore pretend to conclude that all odd numbers are prime, and show this as definitive evidence. Obviously we know what the next prime number is, but there's no way for us to know what the next data set is, and so therefore there's no way to know, based on this, how right or wrong the theory is.


We don't have a second earth to test these theories on. All we can do is model them to the best of our ability. If the models are wrong, we should scrap them. If industrial civilization is around in 2050, then we can conclude that his theories are wrong. This is simply a situation where we will have to wait and see, like global warming.

It is nothing like the math problem you listed above, because primality has a well defined logical structure that we can reason over with an inductive hypothesis. Things that sit inside the logic domain have a different set of properties than the messy world we live in.

$this->bbcode_second_pass_quote('Artanis568', '
')"world per capita energy-use peaked in 1977"

"Peak" implies that per-capita energy usage will keep going down and never go up again. What evidence is provided for this assertion? None whatsoever.


The chart provided at the beginning of this discussion and the charts he provides in other papers show the e cap at around 1977. It has been flat for 30 years.

However it doesn't prove that it cannot go up, as you say. His theory predicts that, however. If his theory is correct, then 1977 will be the "peak". The term is used within the context of the theory. If the theory is wrong, well then everything he says can get thrown out the window.


$this->bbcode_second_pass_quote('Artanis568', '
')Clearly, all the graphs have "peaked" and are now going down, so they will all keep going down until the Atlantic is drained dry.


You are a fan of the association fallacy, I see.

$this->bbcode_second_pass_quote('Artanis568', '
')"The basic behavior of Forrester's world model was overshoot and collapse. It projected that the material standard of living (MSL) would peak in 1990"

This is not only unsupported, but is now obviously wrong. It's 2007 and I'm fine enough.


This is a hasty generalization. You really like your fallacies...

The fact is that the standards of living (as defined by e) for a large swath of planet earth have remained fixed for a long time now.

$this->bbcode_second_pass_quote('Artanis568', '
')"sustainability could be achieved in the modeled world system"

These are numbers, inside of a computer (not even a modern computer, a 1970 computer). They behave according to the rules of if and while statements; they need not bear any resemblance to reality.

This is true for all science. Incorrect models will predict wrong things.

$this->bbcode_second_pass_quote('Artanis568', '
')Honestly, at this point I'm not going to even bother calling all the bold assertions with no supporting evidence. There are too many of them and the same ones are made over and over.

He has lots of supporting evidence... but it is all about one variable. If you really want to take Duncan to task, grill that point.

But given the nature of his hypothesis, only time can prove him correct. We cannot perform an experiment to determine the validity of the hypothesis because we only have one earth.

Olduvai Theory isn't the most sound of the "Post Peak" theories, but if you are going to bash it, try to avoid logical fallacies of your own.

You cannot "prove" global warming either, but the evidence makes it very likely. Duncan uses the same, sound, scientific line of reasoning for his arguments. (but he only uses one variable, so it is much less complex than the IPCC theory.) So talk about variables that you feel he has left out, or undisclosed changes to his e variable that you feel probable. That would raise the bar in the discussion.

How many of you think it is likely that the lights will begin going out in 2008? I noticed that Duncan has moved the cliff from 2012 to 2007 and then, most recently, to 2008. How realistic is to expect rolling blackouts as industrial civilization begins to shudder and collapse in 2008? My take is not likely which makes the entire thing suspect. If it was 2020 or so perhaps but I am not holding my breath for 2008. Thoughts?

Personally I think we have a few more years left of the status quo. As far as the grid goes, I dont neccesarily believe in the assesment that its going to precurse other events. I doubt very frankly that predicting things like this is anything other than a WAG (Wild Ass Guess) and while its possible, It does not look like we are showing signs of a nearing any cliff....yet.

It's a plausible theory but I think we still have more time than he submits. Third world areas may already be there though.

I think the same thing. Lots o' WAGs here.

Also, as interesting as Duncan's writing is, it really doesn't seem all that well supported to me.

Finally, just because you can see the vectors influencing a situation doesn't mean you can tell when it's going to happen. And in my experience, things always take longer than you think.

Well, we are at risk for widespread blackouts in the West due to lack of transmission grid right now.

The Western Transmission Grid: The Urgent Call for Investment


$this->bbcode_second_pass_quote('', 'T')hese outages interrupted electric service to approximately 7.5 million customers throughout the WSCC, and lasted from several minutes to almost six hours. (Since 1996, there have been other outages, but not of the same magnitude.) Given these circumstances, a single point of failure on a transmission line cascaded into line failures across the WSCC.
The West’s long transmission lines — and relatively limited number of alternative transmission paths that result from that configuration — put the region at particular risk for this kind of widespread, high-cost blackout. Given the expected high
utilization of the lines, any major transmission equipment failure could trigger another outage of the same or greater magnitude as was experienced in 1996. This potential for transmission outages in the West is a critical problem.

There's so much that can change..... yes I don't really expect the lights to go out in 2008, but then, we've had a warm winter, could have a very warm summer, the sunbelt has its additional million or so people living it as opposed to last summer, all it takes is some heat waves and people all turning on their A/C (right after the radio's told them to take it easy on the A/C and they get to thinking about it) and we COULD see a grid collapse.

Last summer in the SF Bay Area we had near grid collapse, some hellacious heat waves they told people to keep off the A/C, not sure if most had the discipline, I did, and just hung out in the library with the immigrants and the homeless for those few hot hours lol.

Riots in Karachi due to power outages link, whenever the electricity blackouts start, like Argentina, Zimbabwe, Madagascar, etc, riots ensue, and that's seems to be the point that marks that the decline gets stepper, essential infrastructure not being repaired massive job losses, etc. Duncan was right on the spot.

If some city in Nepal ran out of fuel for it generators would we know; I doubt it. Has anyone heard anything about Senegal lately; the last thing that I heard was on May 17th they stated that the country only had eight days of fuel remaining for its generation plants. There are may back waters of civilization that we don’t know much about, and as they “blink” out we will mostly not even notice. It won’t be until our lights start going out that we will notice, but at that point, like the Senegalese, we won’t have any way of telling anybody.

We have had several short-duration blackouts recently where I work, and a particularly long-duration blackout in the subdivision where I live (Mid-South USA). The work blackouts impacted the business even after power was restored (computer systems, etc.). During the work blackouts we were hamstrung - nothing could get done. I think blackouts are a meaningful precursor of the decline mentioned in the header to this thread. And if you feel, as I do, that we are already IN the decline, then they are symptoms of it, and of the economic woes it will bring.

As far as the population situation is concerned, I have read that the population is increasing, but that the rate of increase is declining. We will continue to increase our numbers and eventually will reach some kind of level, but IMO it will be too late and the numbers will be too great.

Regards,

L.

No, it's more of a warning that places where fossil fuel industry was really trying to thrive are now witnessing it disappear back to insubstantial levels again. For the First World, this will be the shape of things to come.

The least industrialized nations will disappear first, and then the more advanced. This demise will be punctuated by crises; crops will rot in the fields, financial systems will collapse, industries will disappear, and the great web of communicates that we so depend upon, will slowly be broken and blown away, leaving us ever more isolated. The next great Dark Ages will not appear in an hour, it will arrive with stealth; consuming everything in its path, everything that we have so vainly built. The obscure country to which you so casually refer, will in the future - be us.

I have a feeling that, rather than a constant slow demise, the declines will start slowly, and gain speed in an exponential way. As these African countries start to lose power and depopulate, the parts of the western economy that depended on them (food and raw material imports, food exports for example) will start to deteriorate. When those start to go, other parts of the economy will suffer with layoffs and buiness closings, which will effect other parts in an exponential snowball effect, getting faster and more pervasive as time goes on.

People forget what a global web of interdependence we're built up over the last 50 years, and that interdependence is accelerating in complexity even as it's beginning to collapse at the edges.

Someone asked about Senegal. Here's a news story from May 21, about 3 days after the reported "one week of fuel left". The government was "investing" $45 million USD equivalent for fuel purchases because suppliers wanted money up front. The article states they would receive 65,000 tonnes of fuel between May 20 and May 25.

http://www.reuters.com/article/bondsNew ... 4220070521

As long as a country can front the money for fuel it will get it.

We need a list of countries that can't really afford more fuel, and a list of bloggers writing from these countries. They are the canaries, and their blogs are the pulse readings.

Duncan knew what he was talking about making electrical power the basis of his thoughts (predicting blackouts, which are now happening).

We won't get bloggers from those countries who can't buy any more fuel. Blogging would take a satt phone internet connection and those are few in the best of times in the 3rd world, in a country that's about to enter serious dieoff, anyone with that kind of setup would have gotten out of there.

countries like that will simply drop out of the info-sphere, like lights winking out.
