Why
Is this Apocalypse Different than All Other Apocalypses?
Making
the Case for Peak Oil and Climate Change Now
By
Sharon Astyk in Climate Change, Energy
A
lot of what I write works from the assumption that we all agree that peak oil
and climate change are happening and going to be life-changing events. And yet,
some people who read this blog dont necessarily agree on this subject, or
they dont see the effects has being as profound as I do, or perhaps the
idea of peak oil or climate change is fairly new to them, and they are struggling
to grasp the implications. So sometimes, we need to back up, and make the case
for something that is always new to some people. The truth is that if my writing
is to be anything other than preaching to the converted, we have to answer the
skeptics.
Thats
why I was so delighted when I got an email from Frazzlehead who asked me why this
particular energy crisis was different than the one of the 1970s. She observed
that shed been reading 1970s back to the land texts, and finding the exact
same narrative in them that were running out of oil, that soon the
economy will crash and well need to go back to farming. Why, she asked,
is it right this time?
I
look at the date it was written and think, see? Theyve been saying this
for ages and it hasnt happened. Still, something in my gut tells
me that its different this time, that this isnt just a robot waving
its silly arms saying Danger, Will Robinson, Danger! Danger!
that something really is wrong and things will change dramatically.
What
I cant quite put my finger on is the evidence for *this* time being the
*real* time.
Is the Boy just crying wolf again? Or is there really a wolf?
Can
you help me see why *this time* it is for real?
This
is an extremely important question the fact is, ever since the beginning
of the 20th century, when we recognized we really can have World wars,
since the advent of the military capacity to destroy the lives of billions, since
we recognized our impact on the earth, weve been afraid wed destroy
it. How do we know that this time, we really are?
And
of course, this is a good question for climate change as well. Because, theres
a small grain of truth in the oft-repeated claim that in the 1970s, climate scientists
were predicting an ice age only a small one but still. The fact is, many
people remember these predictions of the end of everything, and remember Y2K as
well, and then think the evidence is against those who say things are going
to change. This is a reasonable critique, and one that requires a good answer
or a series of them. That is, it isnt enough to say Well, this
time were right.
The
reason we want multiple answers here is that there are several questions. The
first one is this What are the differences between the scientific and technical
cases for peak oil now, and climate change now, vs. then. But thats
only part of the answer. Because most of us arent climate scientists or
petroleum geologists, and were not going to read every single bit of information
on this subject, so to some degree, we have to rely on our own analysis. We can
weigh the credibility of the technical analyses to one degree or another, but
we also need grounds for distinguishing between those analyses.
The
ideal grounds would be that we completely understand everything the scientists
are saying, but since thats not true, we need another set of analytic tools.
So
the next question we have to answer is this what present day evidence do
we have for each case? How can I see this with my own eyes? And how do the various
available accounts Im being offered match up with both the scientific evidence
and the evidence of my eyes? That is, both the disasters are coming
and the itll never happen crowds are telling stories
they are giving an account of the past and the future. Picking the right story
depends on our being able to match up evidence with the narrative being provided
to us.
And
while those two data points are convincing, they arent everything we need
to know to make a decision we also need to ask ourselves how to apply an
imperfect case for something. That is, assuming that very few things about the
future can be known with absolute certainty, we need to know what the case for
action is that is, how should we use the information above? What tools
of analysis will get us the best results?
Im
going to go through these questions, one at a time, to the best of my ability.
Because the subject is such a long one, this will appear in two parts.
First,
the technical analysis:
First
of all, what was the evidence for 1970s style depletion analyses? Im going
to admit here that I am somewhat handicapped on this question by having been born
during the 1970s oil crisis that is, I have no direct experience of the
data that was coming in during that period I was busy analyzing the comparative
merits of growing up to be a garbage collector (cool truck) or a vet (cool puppies
and kittens), and thus not paying much (any) attention to petroleum geology.
Ive
done no real research into the accounts coming in during that period, either.
So I honestly cant personally tell you how good the 1970s accounts actually
were. That is, I havent seen them. Ive seen the same accounts Frazzlehead
has, popular narratives in which we were running out of oil but not
any scholarly accounts that make that same claim. This is not to say that there
werent any, just that Im unfamiliar with them.
In
fact, peak oil theory doesnt make the claim that were running
out of oil either, except in the sense that whenever you make any use of
a non-renewable resource, you are reducing the amount thats left and contributing
to the larger process of running out. The peak of oil production occurs
at the moment that we have used ½ of the oil in the ground. No peak oil
scholar that Ive ever seen has suggested that we are in immanent danger
of having the world run out, but rather that demand (how much oil wed like
to burn) will exceed supply (the amount we can get out of the ground). Some consequences
under the current systm of this difference between demand and supply would be
higher prices, spot shortages, poor people being priced out of the market altogether,
and gradually more and more people being priced out or having their usage dramatically
reduced. But thats not the same as actually running out.
It
is safe to say that if people in the 1970s were claiming that we were in immanent
danger of running out, they were really, really deeply mistaken and that
that mistake cant be chalked up to improvements in science. But I suspect
that most scholars werent saying that instead, they were saying something
more complicated and nuanced, and, as is often the case, complicated, nuanced
ideas got dumbed down to something less accurate but more exciting sounding.
To
get some evidence of this, lets look at _The Limits to Growth_ which was
perhaps the single most famous text that said we were running out of oil
in the 1970s. But, of course, thats not what it said at all. Im going
to quote here Richard Heinbergs analysis of TLTG, because I think he covers
all the salient points:
Several
economists have attempted to debunk the conclusions presented in LTG. For example,
in _Eco-Scam: The False Prophets of Ecological Apocalypse_, Ronald Bailey wrote
that In 1972 The Limits to Growth predicted that at exponential growth rates,
the world would run out of gold by 1981, mercury by 1985, tin by 1987, zinc by
1990, petroleum by 1992, and copper, lead and natural gas by 1993. _Facts
Not Fears: A Parents Guide to Teaching Kids about the Environment_ by Michael
Sanera and Jane S. Shaw repeated part of this list and pointed out that The
world did not run out of gold by 1981, or zinc by 1990, or petroleum by 1992,
as the book predicted.
However,
these were not predictions contained in the book. The reference for these claim
is Table 4
The table lists three sets of numbers: a static reserve index
(how long known reserves would last at 1972 rates of consumption); an exponential
reserve index (how long known reserves would last at an exponentially increasing
rate of consumption); and an expontential index calculated using five times the
known reserves (that is, assuming substantial new discoveries of the resources
in question). Criticisms of LTG focused only on the second, exponential
reserve set of numbers which was the most pessimistic, even though the authors
clearly stated that this did not constitute a prediction, but merely a statistical
extrapolation. (Powerdown, 93-94)
That
is, critiques of _The Limits To Growth_ were made out of context. The authors
knew that it was very, very unlikely that we would have massive growth of consumption
without any new discoveries, and werent proposing that would happen
they were providing context for their larger conclusion that we are at risk of
overshoot.
In
fact, _The Limits To Growth_ was probably fairly accurate in their overall claims,
as the updates have demonstrated.
It is important to note that TLTG made the
claim, to the extent it claimed things, rather than observed them, that collapse
was likely to come not in the 1970s, but at the very end of the 20th or beginning
of the 21st century.
That
is, they claimed that *overshoot* - the point at which we were exceeding the capacity
of the earth to sustain us would happen earlier than that and in fact,
theres compelling evidence they were right. But they never claimed that
the crisis point would be reached at the same moment we reached overshoot
instead, they suggested otherwise. This is an important distinction. That is,
TLTG emphasized how urgent it was that we begin to make policy and practical changes
that would abate the crisis in the 1970s that was the time to respond.
But those policy changes were designed to avoid an outcome that would occur decades
later and they are occurring decades later as predicted.
Richard
Heinberg has actually claimed that he hasnt been able to find a single example
of any peer reviewed paper predicting we were actually going to run out of oil
in the 1970s and yet, many people knew that this was the case.
I dont know if that fact is still true even if there are some, that
doesnt mean they were right. But there certainly arent a large number
of them.
What
was true in the 1970s, is that *American* oil prediction hit its peak. In 1970,
American production peaked, just as M.King Hubbard said it would. At the time,
nearly everyone denied that Hubbard was right after all, wed just
produced more oil than we ever had before why would we expect shortfalls?
Well, the reality is that thats just how it works the peak is the
point at which you produce more than you ever have or ever will again.
So America actually was experiencing serious oil shortfalls, and because of the
OPEC embargo, was unable to meet demand.
Looking
through my collection of older back-to-the-land accounts, I see several of them
claim that we cant depend on foreign oil. And that may be at the root of
our belief that we thought we were running out in the 1970s we believed
that America would largely have to rely on its own oil supplies, which were patently
inadequate to meet even 1970s demand. In that sense, we were running out
of oil because we had ample evidence that we might not always be able to
buy it, and our supply was inadequate. That politics changed, and the bottom dropped
out of the oil price, giving OPEC incentives to keep our supply coming was a great
result but if the embargo had continued, we might genuinely have been running
out that is, supplies of oil arent just absolute, but the ones you
have access to.
Thats
an important point on peak oil because access has as much effect as absolute
reserves. So, for example, an oil crisis could arise because of our inability
to increase imports, or because of structural failures in refining capacity that
cause shortages before the absolute peak, or because of geopolitical issues. On
the one hand, peak oil is a very simple idea. On the other, if you interpret the
term to mean the point at which supply can no longer meet demand it
gets very complicated. For example, many poor nations can no longer afford to
import oil at all, and are suffering because of that. For them, peak oil is already
a reality.
In
fact, the 1970s oil shocks offer a useful kind of support for the claims of peak
oil in the present. The oil shocks were fundamentally political in nature, but
they also offer proof of the fact that a. there are peaks, and b. such peaks are
inherently disruptive. The reduction in available oil in the US after its peak
left us in a tough spot, politically speaking, and vulnerable to supply constraints
caused by outside forces. Several peak oil scholars have correlated regional peaks
with periods of societal disruption that is, when we experience substantial
declines in resource access, it causes major problems.
The
same argument can be made about the frequently quoted claim that in the 1970s,
scientists were predicting an ice age, and now they are predicting catastrophic
warming. In fact, in the 1970s, there was some discussion of the possibility of
a new ice age, for several reasons. The first is that in the 1970s, particulate
emissions, that is, pollution, was so severe that it caused a considerable cooling
of the planet. So it seemed possible that we were entering a cooling cycle.
We
were also statistically at the end of a period of climate stability, and the possibility
that there might be an ice age was discussed. But even Richard Lindzen, one of
the formest Global Warming skeptics, has admitted that this was never more than
the equivalent of scientists batting an idea around. That is, there never was
any strong scientific consensus that we were entering into a period of global
cooling *and* most research on this subject was speaking only of natural cycles.
For
example, perhaps the most famous article on this subject appeared in Science in
1976, and included the phrase in the absence of human perturbation of the
climate. That is, the prediction that global cooling would occur was *explicitly*
made with the caveat that if we mess with the climate this probably wont
happen. But, as usual, the nuance was removed, and what we get is the idea that
we once were really sure we were going to have global cooling.
It
is also very important to note that scientists *also* were predicting Global Warming
well before the 1970s. A Swedish chemist named Arrhenius discovered and predicted
global warming at the turn of the last century, documenting that it was already
underway. Charles Keeling was doing work on Global Warming in the 1950s and 60s,
and continued to do this work until his death in 2005. In 1979, as Jimmy Carters
Global 2000 report was being compiled, anthropogenic global warming was cited
as one of the most serious problems of the century. So it would be more accurate
to say that in the 1970s, there was considerable debate over whether warming or
cooling would be the primary concern, and by the end of that decade, there was
a growing consensus that global warming was far more likely.
In
both cases, one of the most important bits of evidence is the degree of scientific
consensus that is, the sheer number of scholars and researchers that agree
that they are seeing evidence of something. Since these scientists will generally
come at this issue from different directions one person studying ice melt
in the arctic, another sea level rises, one petroleum geologist studying future
projections, another talking about the history of discovery. So while hardly infalliable,
scientific consensus matters.
And
in both cases, we can claim that there is an enormous difference between scientific
consensus now and scientific consensus then. For example, consensus on global
warming is overwhelming. The oft-stated claim that there are no peer-reviewed
scholarly articles that cast real doubt on the anthropogenic (human caused) nature
of climate change is probably not quite true, but there are very few of them -
a handful at best, mostly in minor journals, and compared to 10,000 and more such
articles in peer reviewed scholarly journals that take the other position. There
are a few real scholars (and a bunch of paid shills for the energy industry) who
sincerely believe that climate change is not anthropogenic (theres no one
who doesnt believe the climate is changing, btw), but the reality is that
there are tiny, dissenting minorities on every scholarly community. It is still
possible, for example, to find a few doctors who dont believe cigarettes
cause cancer. It is still possible to find some historians who dont think
the Holocaust ever happened. But these are few, and they dont change the
fact that the overwhelming majority believe otherwise, and, more importantly,
that the overwhelming majority of the evidence supports anthropogenic global warming.
In
regards to peak oil, the scientific consensus is actually harder to figure out.
Every once in a while I run into someone who is a peak oil believer and a global
warming skeptic, which I find quite funny. That is, the scientific evidence for
global warming is so much greater than for peak oil (which in no means implies
that both are not true, merely that there is less certainty and less research
in regards to peak oil) that it seems odd to me that one could evaluate the evidence
for the less certain one, agree with it, and then dismiss the evidence for the
other.
But
saying that theres more controversy in the study of peak oil that climate
change is not to say that there is no scientific consensus on peak oil. In 2007,
the General Accounting Office of the US Congress released a report that argued
that a majority of relevant scholars and oil experts now believe that a peak has
already happened or is immanent. There are still significant dissenting viewpoints
notably Cambridge Energy Research Associates (CERA) and the International
Energy Agency (IEA), but both are showing chinks in their armor as oil prices
rise and as we get several years away from what seems to be our production peak,
in 2005. The IEA, for example, this year admitted they anticipate supply constraints
into the 2040s which is effectively an acknowledgement of peak oil, since
virtually no serious assessments put the peak that late the US Geological
Survey, for example, puts the world peak at 2023.
The
truth is that it is very hard to predict an oil peak, except in hindsight. At
the 2006 ASPO (Association for the Study of Peak Oil) conference, I heard peak
oil researchers give dates that ranged from 2012 or later to 2005 so even
the experts who do believe in peak oil are uncertain. Because there is no reliable
reserve data on total available oil, we can only look at the history of our discoveries
(that is, discoveries peaked in the 1960s since then weve been finding
a dramatically decreasing amount of new oil each year, despite all the people
who hype each new discovery as the answer), how much of the globe has been mapped
for oil (the vast majority) and estimate likelihoods. And also, we can do the
math showing current rates of decline (most of the major producers are declining
significantly), and look at how much oil wed need to find in order to put
off the problem. The answer is a hell of a lot that is, as
Matthew Simmons put it, even if we found a massive oil field, as big as the North
Sea, for example, it would only delay the whole worlds oil peak by a matter
of months.
The
next question would be how well the predictions, model and data match up with
what were actually seeing right now. For example, in regards to peak oil,
while we dont know whether or not the Saudi giant oil fields have actually
peaked, we can look and see what is actually happening in the world. Some Saudi
authorities claim that the peak is a long way out, others that it is very near
(many oil company executives now openly admit peak oil). But right now, oil prices
are at very nearly the world record. When prices are extremely high (and they
have been for several years now), generally speaking the laws of economics would
suggest that people have the incentive to make as much money as they can, by producing
as much of this high priced stuff as possible. In fact, however, the Saudis have
made voluntary cuts now several years in a row. It is possible that
OPEC and the House of Saud has said, Were rich enough we simply
dont want any more money. But how likely is that? More credible is
the idea that they cannot increase production due to physical constraints.
The
fact is that overall, world oil production is either stagnating or falling in
most areas. Explaining this fact requires a credible reasoning. Market forces
certainly arent driving the decline anyone with oil has an incentive
to sell it now. In some cases, there are technical problems with extraction, or
other limits that can explain this, but these explanations are insufficient to
describe the overarching trend. On the other hand, peak oil theory explains it
in two ways. The first is that actual output has plateaued or is beginning to
decline. The second is that if we know that, more nations will withhold some of
their oil for the longer term, both for their own use, and to sell later on. If
we have plenty of oil, it would be crazy of producers not to take advantage of
record high prices. If we dont, we can assume that in fact, high prices
will continue, and even rise higher. Peak oil theory fits the facts.
The
same is true with climate change theory. For example, climate change dissenters
often argue that the sun is sending more heat our way. But if that were true,
wed be seeing more warming in the upper atmosphere as well as closer to
the earth. But in fact, the opposite is true the upper atmosphere is cooler.
Since the suns rays have to go through the upper atmosphere to get to the
earth, thats not consistent. But if the earth itself is trapping carbon
and increasing heat, it would make sense that we would find the upper atmosphere
cooler than the lower.
The
correlation of manmade C02 levels with planetary warming is another place we can
see the evidence of global warming. The ice reductions in the arctic, and the
thinning of the edges of the Greenland and Antarctic ice sheets are another.
That
is not to say that there is no inconsistency in climate systems we are
talking about a large, enormously complex system, being modeled by thousands of
researchers. It is not an easy thing to figure out, and not every bit of data
is going to be perfect. But the overwhelming reality is that the story here fits
the data extremely well the account of anthropogenic global warming fits
what we are seeing if anything, we have tended to underestimate our impact.
We
can also see the evidence of our own eyes in both cases - we can see the rise
in food prices, gas prices, the warming of our regions, the changes in planting
zones and snowfall, the increased frequence of drought. These are not sufficient
evidence - any one year, any one locality can be explained. But there is no doubt
that billions of people around the world are seeing these things, and that our
vision is a small piece of the picture.
Going
back, for a moment, to _The Limits to Growth_, one of the things that appears
a lot in later modeling, in, for example, the 30 Year Update of TLTG, is that
feedback loops and intersections are a bigger problem than any individual problem.
And for those people wondering whether these problems are really as bad as they
think they are, this is probably the most important thing to know in the
1970s, we were worried about individual problems a shortage of oil, for
example, or about pollution, or a coming ice age. Right now, the biggest concern
we have is of the intersection of inter-related problems. That is, the problem
is not our ability to respond to one problem, but our ability to respond to multiple,
overwhelming simultaneous crises.
_The
Limits to Growth: The Thirty Year Update_ found that almost all its business
as usual scenarios led to collapse , *EVEN IF* the sheer quantities of resources
available were *DOUBLED* over what we have any evidence at all for that
is, even if we had enough energy to go along, pollution built and cancer rates
skyrocketed, while soil erosion rose to make food production fail to keep pace
with population growth. That is, these scenarios dont depend on a shortage
or crisis in any single place they operate as a system of feedback loops
influencing one another. As the authors put it,
A
second lesson is that the more successfully society puts off its limits through
economic and technical adaptations, the more likely it is to run into several
of them at the same time. In most World3 runs, including many we have not shown
here, the world system does not totally run out of land or food or resources or
pollution absorption capability. What it runs out of is the ability to cope.
(TLG30, 223)
In
the 1970s, environmental activists were responding to the very first warning signs
of depletion and climate change. Many of them interpreted scientific warnings
on these points to mean that we were facing an immediate, definite crisis down
to the particulars. But thats not what they were being told. Instead, people
were being warned about the longer term consequences of their actions in no uncertain
terms. And in fact, our ability to cope managed to push these issues off, in many
cases for decades, but again, as we put our limits further off, we drew our resources
down further. Soon, the bill comes due.
Now
this is all a fairly compelling case, but it isnt all the truth that ever
was, and anyone who tells you otherwise is lying. That is, there is absolutely
no point in exaggerating scientific evidence to pretend we know everything with
perfect, utter certainty. So my next post will be about the question of how we
use this data that is, if we think the odds are strongly in favor of something,
but we dont have perfect certainty, how do we know what to do? There are
logical tools for that, and my next post on this subject will discuss them.
