***{Of course sulfates exist, and of course anaerobic sulfate-reducing
bacteria exist. The assumption that a significant portion of the oxygen
presently in the atmosphere came from such a source, however, does not
work. The reason: sulfate reducing bacteria do not release oxygen into
the environment. What they do is strip away the four oxygen atoms out of
the sulfate radical, and then use them to change carbon containing
compounds (e.g., methane, crude oil, compost, etc.) into carbon dioxide
plus water. In other words, they burn carbon compounds as fuel,
producing CO2 and H2O as waste. To do that, they need oxygen. Since free
oxygen isn't available in anaerobic environments (by definition), they
pull the oxygen they need off of any sulfates that happen to be
available. The fact that they don't release free oxygen into the
environment is not surprising, for two reasons:
(1) Investing the energy to pull the oxygen out of the sulfate would
make no sense, if they immediately turned around and released the oxygen
into the environment.
(2) Since sulface reducing bacteria flourish in anaerobic environments,
they would be disadvantaged if they were to bring about aerobic
conditions by releasing free oxygen. (Hey, that would encourage the
competition! :-)
The implication is straightforward: sulfate-reducing bacteria exist, but
they release CO2 and H2O into the environment, not O2, and thus their
presence does not affect in the slightest the calculation of the amount
of carbon that was freed up when the O2 in the atmosphere was produced.
You don't have to subtract the portion of atmospheric oxygen which
sulfate-reducing bacteria produced, because they didn't produce any of
it.

***{Irrelevant. The slash between CO2 and carbonate in the expression
"CO2/carbonate reservoir" means that either or both may be present. I
lumped CO2 and the carbonates together into a single reservoir because
the carbonates are produced from CO2, and the carbonates, once formed,
are eventually subducted back into the Earth's interior, where the CO2
is again released. (This is the source of the massive amounts of CO2
that emanate from volcanos.) That means it doesn't matter whether
carbonates were present "at all" on the primitive Earth, because there
was plenty of CO2 available at that time, and that is sufficient to
establish the existence of the primordial CO2/carbonate reservoir.

oxygen, they do not release it. What they release is carbon dioxide.
Result: all of the oxygen in the present atmosphere, as a practical
matter, came from the primordial CO2/carbonate reservoir. Result: the
calculation of the amount of carbon freed up when that atmospheric
oxygen was produced, given previously, is a good working approximation
to the truth. --MJ}***

What is nothing is the argument by which you attempted to dismiss the
significance of that reservoir. That argument, which depended on the
false premise that sulfur-reducing bacteria release oxygen, is obviously
in ruins. --MJ}***

***{We will get to it incrementally. As new technology comes online
which allows profitable extraction of some portion of it, we will
extract that portion. Then, later, when other new technology comes
online that allows profitable extraction of another portion, we will
extract it. And so on. The process will continue until we no longer need
those materials, or until more easily exploitable new reserves--e.g., on
Titan--become accessible. --MJ}***

***{It is futile, from the perspective of presently known technology, to
attempt to identify the technology of the future. What matters is that,
if men are free to create, invent, and discover, they will continue to
be able to provide for their energy needs; and if they are not, they
will not. All the calculation proves, in short, is that the energy is
there and that our advancement as a species will not be stopped by "peak
oil" or by any other external limitation. If we are stopped, it will be
because we submitted to the will of parasites, and for no other reason.

***{Do you believe that? If so, why? It does seem like a rather foolish
notion, now that you mention it.
My view, which you can review in the material quoted above, is that "in
all likelihood, the total from the two sources would permit in excess of
200,000 years of usage at current rates of consumption." As you can
plainly see, I placed a qualifier at the end of the sentence--to wit:
"at current rates of consumption." Given that qualifier, any technically
competent person can easly determine that, if average consumption is
higher, the duration of allowable usage will be less. If, for example,
average consumption in the future is twice the current rate, then we
will have in excess of 100,000 year of usage. And so on.
I'm sorry if the numbers seemed scary to you. It's really pretty simple
arithmetic, once you focus your mind on it. :-)

***{Incorrect. Earth's primordial CO2/carbonate reservoir originally
consisted almost entirely of CO2. That material was originally part of
the primordial disc from which the solar system formed. In solar system
formation, what basically happens is that the primordial disc coalesces
into a cloud of comets, and, the bashing together of comets produces
larger bodies, some of which become planets. Eventually, one of the
planets becomes large enough to support fusion, and turns into a star.
As soon as the first star lights up, a solar wind appears, and
temperatures near to the star become high enough to support the loss of
volatiles from orbiting bodies. There is then a sorting process, based
upon the size of the various bodies and their proximity to the stellar
mass (or, in some cases, the stellar masses). The details of that
process are irrelevant here, but the point of interest is this: pristine
cometary material is the original primordial material from which the
solar system formed, and it includes a number of ices, prominent among
which is CO2. Hence Earth's primordial CO2/carbonate reservoir preceded
the emergence of life on Earth, and, indeed, preceded even the lighting
up of the sun. Your statement that it came from oxygen that had been
previously produced by plants is palpably wrong. (If you doubt this, do
a web search on the keywords "comet" and "composition," and read some of
the articles that you find.) --MJ}***

***{It depends on the political system. Under capitalism, just about
everyone can reasonably expect that his property rights will not be
violated, because government has been sufficiently restrained that
virtually all criminality comes from private sources. Since criminality
unassisted by government is a feeble thing and easily dealt with, it
ceases to be a factor impeding social progress. As a practical matter,
under capitalism each person is the owner of that which he creates,
invents, discovers, or obtains through voluntary exchange. Such rights
are a powerful incentive, and the result is an orgy of creation,
invention, and discovery which continues until such time as the
political system, capitalism, has been abandoned, and the store of
capital accumulated under its auspices has been consumed. The
consumption phase, in most cases, takes place in the context of fascism.
Under fascism, the government reserves unto itself the privilege of
violating property rights in what it deems to be "the public interest."
Since the "interests" in question are always those of would-be social
parasites, fascism is inherently unstable. It always leads to an orgy of
state-sponsored criminality, and if it is allowed to endure until the
previously accumulated capital has been consumed, it results in economic
and social collapse, followed by poverty and authoritarian slavery. The
implication: if we can somehow manage to restore, and then retain, the
capitalistic system, technology can, and will, progress indefinitely. As
to whether we can do that, only time will tell. (I must say, though,
that in my judgment the game is already thoroughly lost.) --MJ}***

***{If it were an important point, I would try to come up with one, but
it isn't. Remember the issue: I spoke in support of Hanson's
calculation, which supported the conclusion that merely freeing up the
oxygen presently in the atmosphere left behind enough carbon for more
than 100,000 years of usage at current rates of consumption, and you
denied that conclusion. The premise of the calculation was that
substantially all of that oxygen came from the primordial CO2/carbonate
reservoir, and unless you can budge that premise--which you haven't--you
are toast. That means the magnitude of the primordial methane reservoir
is irrelevant to the issue. If one molecule of methane from that source
remains on Earth, it is a molecule added to the already gigantic carbon
stockpile which supports Hanson's calculation. Hence focusing our
discussion on that would amount to chasing a red herring, and, while
that might please you, I ain't gonna do it. --MJ}***

***{You deem it "imaginary" because you believe that sulfate-reducing
anaerobic bacteria release oxygen into their environs, thereby
encouraging aerobic competition. That belief, however, is erroneous.
When anaerobic bacteria need oxygen, they can't simply grab an O2,
because there aren't any around. (That's what "anaerobic" means.) Thus
they invest energy to rip an oxygen loose from something else--a gypsum
molecule, say--and incorporate the oxygen into whatever organic molecule
they are building. That means the oxygen goes into a carbon based
molecule, and, when that molecule is eventually used as fuel, the oxygen
goes off as either CO2 or H2O, not as O2. --MJ}***

***{As noted previously, technological improvement is an incremental
process. The "easy" problems are solved first, creating a new
technological context, from which a new set of "easy" problems emerges
and is solved, which in turn creates another new context from which yet
another set of "easy" problems is solved, and so on. No human can
reliably predict where such an iterative chain will lead, any more than
any billiards player can reliably predict where three and four ball
combination shots will lead. All we can do is create the
conditions--respect for property rights--which encourage such
improvements, and wait until hindsight tells us where things were
headed. If we do that, we are all absolutely guaranteed to be surprised
by the result, but that is not what matters. What matters is that the
surprises will be pleasant, meaning that our lives will improve because
we had the courage to let it all happen. --MJ}***

***{Oh, please, let's not get silly. When I referred to "carbon freed
from the CO2/carbonate reservoir," I had in mind "carbon freed from the
CO2/carbonate reservoir by the extraction of O2," and this far down into
the discussion you ought to be perfectly aware of that fact. And,
obviously, if the O2 is extracted from CO2, "atmospheric CO2" is not
what remains. What remains, instead, is carbon, in the form of organic
compounds created by the plants that extracted and released the
O2--e.g., complex sugars to start with, followed by lipids, wood, etc.,
and, over geological time, crude oil, lignite, coal, etc. Now let's get
serious here, OK? --MJ}***

***{Artificial photosynthesis is not needed to make use of hydrocarbons
accumulated over the aeons by natural means--i.e., by green plants using
photosynthesis to convert solar energy to chemical energy. The O2 was
extracted from the CO2 and released into the air. The carbon that
remained was assembled, first, into molecular forms which we call
sugars, thereby storing the incident solar energy in chemical form. An
example reaction is 6CO2 + 6H2O + solar energy --> C6H12O6 + 6O2, with
the O2's being released into the air. From there, using the energy
stored in the sugar, other complex organic molecules were fashioned such
as those mentioned earlier, which eventually led to storage of the
energy over geological time spans in the form of crude oil, lignite,
coal, etc. --MJ}***

***{As technology advances, that which is "readily accessible"
incrementally improves. Obviously, you don't begin 200 km down. You
start near the surface and work your way lower as technology improves--
and that's what, in fact, has been taking place. --MJ}***

***{It's not static, Tom. The fact that a particular natural resource
cannot be profitably extracted today does not mean it cannot be
profitably extracted in the future. Extraction technology advances by
finding cost-effective new techniques that yield profits. As long as all
of the known techniques yield losses, the resource remains undeveloped,
awaiting the needed improvements. That's the way natural resource
development has always worked, in market economies. How could you not
know that? --MJ}***

***{I repeat: "the material freed from the CO2/carbonate reservoir" is a
reference to material that remains after the extraction of oxygen. When
the oxygen is extracted from a CO2 molecule, a CO2 molecule does not
remain. What remains is a carbon atom, and that carbon atom is
immediately utilized, via the metabolism of the plant which has hold of
it, to add to the structure of an organic molecule. Thus the fact that
CO2 doesn't burn is irrelevant. The organic molecule that remains after
the O2 has been extracted does burn, because the energy invested to pull
off the oxygen will be given back if, at some point in the future, the
reaction is reversed. --MJ}***

free to advance, cost-effective ways to access the Earth's massive
