-
- This essay describes some philosophical, ethical, and cosmological
- implications of the Gaia hypothesis. Although loosely grounded in
- recent research in ecology and paleoclimatology, this is clearly an
- essay and not a scientific paper. It is also distinctly tongue in
- cheek, but the author has spent some serious moments wondering
- whether the belief system outlined below is any more unreasonable
- than certain "mainstream" viewpoints.
-
- * * * *
-
- Over the last few years, we've become familiar with the notion that
- the biosphere is a dynamic, self-regulating system. In fact, an even
- stronger assertion can be made: the biosphere, in its present oxygen-
- rich form, is "a kind of superorganism that in its entirety maintains
- the conditions that best suit life on earth." [1] This formulation,
- known as the Gaia Hypothesis, was originally advanced by naturalists
- James Lovelock and Lynn Margulis (novelist William Golding suggested
- the name.)
-
- A key point in the Gaia hypothesis concerns the stability of the
- carbon cycle: that the level of atmospheric CO2 has been maintained
- within relatively narrow limits for hundreds of millions of years.
- This point is critical because the temperature of the biosphere
- is largely controlled by the quantities of greenhouse gases
- (primarily CO2) in the atmosphere. Various geophysical and
- biological processes cooperate to lower the amount of free CO2
- when the biosphere warms, and release CO2 when it cools. Thus
- the assertion that CO2 has remained relatively constant is also
- an assertion that the temperature has remained within relatively
- narrow limits: at no time in the last billion years has the Earth
- been a pressure cooker like Venus, or a snowball like Mars.
-
- This essay contends that over geological time periods (in particular,
- over the last 500 million years) the amount of available carbon in the
- biospheric carbon cycle has slowly decreased. This decrease has been
- driven by long term processes that remove CO2 from the atmosphere and
- deposit it in rocks. Plants, for example, capture free carbon in the
- molecules making up their tissues. As the plants die, their carbon
- sometimes leaves the dynamic biological domain of the "carbon cycle"
- and enters the geophysical domain as "hydrocarbon deposits" (coal,
- oil, and seafloor sediments.)
-
- Various pieces of indirect evidence exist for this slow decline in the
- CO2 content of the atmosphere. Numerous plant species, for example,
- thrive when subjected to an atmosphere lower in oxygen and higher in
- CO2 than the current atmosphere of Earth. It is natural to suppose
- that this beneficial effect is a holdover from the bygone era in which
- the photosynthetic "apparatus" of these plants evolved; their initial
- evolutionary "best fit" has slowly become a "misfit" due to decreasing
- levels of atmospheric CO2 across intervening megalenia. Some direct
- evidence of CO2 decrease also exists in the form of ice cores [1, p 42]
- although it covers a much shorter time scale.
-
- It is true that several arguments for the "essential stability" of the
- atmospheric CO2 level exist, in addition to well-understood mechanisms
- that "reverse the process" by removing carbon from the geophysical
- domain and returning it to the biosphere (that is, the domains are not
- truly separate.) It has been widely observed in the literature that
- CO2 levels could never have _fallen_ to less than one-third of their
- current value, nor could O2 levels have _risen_ significantly from
- their current values, without deadly consequences for life [2].
-
- The author finds these arguments too weak to deflect the main thrust
- of this essay. None of the data presented in Garrels et al [2] appear
- to rule out the possibility of somewhat higher atmospheric CO2 in ages
- past. In fact, their discussion of the carbon cycle gives short shrift
- to "reservior five" - organic carbon locked up in sediment. It is the
- relationship between humankind and this crucial reservior five that we
- will now continue to explore.
-
- As we've shown, conventional reasoning links the general stability of
- the carbon cycle to the general stability of biospheric temperature.
- This same reasoning also serves to link the slow decrease in CO2 to an
- equally slow (yet systematic) cooling of the biosphere. The Gaian
- temperature "equilibrium" is not, in fact, stable. Across geological
- eons, the Gaian feedback system achieves not stability, but rather a
- slow cooling. Various evidence for this cooling trend exists [5].
-
- Of course, the Gaian system is quite robust - as evidenced by its
- repeated recovery from the effects of barrages of big rocks from
- outer space. As Gaia ages, however, it is faced with the threat
- of a calamity worse than the impact of a dinosaur killer. This is
- the threat of "cold equilibrium", more colorfully called "the White
- Earth scenario."
-
- The White Earth scenario is part of the dirty laundry of the climate
- modelling community. As noted in Gleick's "Chaos: Making a New
- Science" [6], some seemingly reasonable (although simple) climate
- models suffer from an odd characteristic of falling into a state in
- which much of Gaia's free water is locked up in snow and ice; the
- surface albedo of the planet is high; and no obvious mechanism for
- increasing atmospheric greenhouse gas content or otherwise warming
- the planet presents itself. Since this state does not seem to
- correspond to anything in the historical record of the Earth, it
- is regarded as anomalous and incorrect.
-
- I suggest that we take take a truly novel approach to these seemingly
- valid models that drop into the White Earth state: let's presume that
- they are valid, and that they are telling us something important. We
- are at risk of "cold equilibrium" in the near geological term.
-
- The ability of the paleoclimatological community to accumulate the
- data leading to this conclusion and then avoid the conclusion itself
- is quite astonishing. One paleoclimatologist [4] has the audacity to
- draw a graph of Gaian temperature that trends smoothly downward for
- many millions of years, but is suddenly consumed by a series of sharp
- vertical excursions ("wiggles") over the past few hundred thousand.
- It's similar to the graph of a coin which rolls slowly around in a
- large circle, then rattles rapidly around in an oscillating spiral
- for a few moments before coming to rest in an equilibrium state,
- stable and dead - Gaia converges on the White Earth.
-
- Now let's take a step back from this impending frozen death for a
- moment. The key to the Gaian system is that it is *self-adjusting*.
- As observers who have only recently had our eyes opened to this
- wonderful concept, the Gaian model, we cannot hope to appreciate
- the myriad ways this all-encompassing system might find to regulate
- itself - to adapt to conditions and to maintain the equilibrium
- necessary for life. We must not underestimate the ability of the
- Gaian organism to evolve temporary organelles designed to deal
- with crisis.
-
- The last 100,000 years have seen some of the coldest times in the
- 500 million that have elapsed since the Ordovician period. These
- 100,000 years form less than 1/1000th of the intervening 500 million
- years.
-
- Oddly, they're the same 100,000 years that Homo Sapiens Sapiens has
- existed on Earth.
-
- Clearly, the biosphere has reached a point of crisis. The relatively
- stable processes of self-regulation that have worked for the past
- hundreds of millions of years have reached the limit of their ability
- to correct.
-
- In response to the impending crisis, Gaia evolved a solution. At the
- edges of the ice sheets that flowed down over the northern hemisphere
- during the last ice age, Gaia brought it to fruition: a short term
- corrective process designed to restore the natural balance of free
- carbon dioxide in the biosphere.
-
- Man.
-
- Yes, Man. Not the destroyer, the pillager, the environmental
- rapist of the popular lore; an utterly different view of Man the
- restorer, the savior, the solution to an environmental crisis more
- dangerous to the biosphere than even the giant stone that ended the
- age of dinosaurs. Man, whose only purpose in the Gaian system is
- to extract carbon from the rocks and put it back in the atmosphere
- where it belongs.
-
- It is not far-fetched to suggest that the evolution of mankind is
- an adaptive reaction. Organisms under stress are known to exhibit
- all manner of extraordinary behaviors. It is likely that
- Levenson's "one last coincidence" [1, p 56] is not a coincidence
- at all -
-
- From 1500 to 1850, throughout the Little Ice Age, the
- nations of Europe expanded in population, power, techno-
- logical competence, military strength, economic endeavors,
- in world rule - in virtually every measure of the vigor
- of a civilization.
-
- No, it is not a coincidence at all. It is, quite literally, our
- destiny; that is why we are so well equipped to succeed and expand
- our CO2-returning practices during periods of intense cold.
-
- The climatological community has come close to the point:
-
- Within a few centuries, we [human beings] are returning
- to the atmosphere and oceans the concentrated organic
- carbon stored in the sedimentary rocks over hundreds of
- millions of years [3].
-
- But as scientists, the community lacked the zeal to make that
- final, fundamental leap from observation to motive - the observation
- that this is not merely an unanticipated side effect of intelligence,
- but the very reason for its existence.
-
-
- Post-Gaian Environmental Ethics
-
-
- Given this recognition of mankind's role in the Gaian system, it
- is possible to construct a consistent system of environmental ethics
- that might be called "Carbonism."
-
- - Carbonists hold viewpoints that differ significantly from widely
- accepted environmental viewpoints, but Carbonists are not wanton
- destroyers of the environment. Carbonists do not favor poisoning
- the environment with long-lived toxins such as heavy metals or
- radioactive nucleotides, the accumulation of solid waste, or any
- other practice that does not contribute the the increase of CO2
- in the biosphere.
-
- Carbonists do hold, however, that other concerns are outweighed
- by the prospect of even a small increase in the necessary CO2 in
- Gaia's thinning veil.
-
- - Anything that has the direct effect of taking carbon from the
- geophysical reservior and returning it to the atmosphere is good.
-
- - Burning coal and oil for heating or to produce electric power
- are the greatest goods. Temporary particulate pollution of the
- atmosphere associated with these practices are of no consequence.
-
- - Automobiles are very good. Automobiles contribute other
- greenhouse gases, in addition to CO2, all at a minimal cost
- in annoying particulate pollution.
-
- - Burning wood is good. Logging is good. Slash-and-burn
- agriculture is good, particularly when it is done to raise
- ruminants (cud-chewing animals) which themselves contribute
- nontrivial quantities of greenhouse gases to the atmosphere.
-
- - Eating red meat is good. Consumption of red meat has an amazing
- ability to act as an economic incentive for slash-and-burn
- agriculture and the cultivation of ruminants in the tropical
- regions of the world.
-
- - Hydroelectric and Nuclear power are bad. They replace beneficial
- coal and oil burning. Dams are also harmful to fish, and harming
- fish has no evident CO2 benefit - Again, Carbonists are not wanton
- destroyers of the environment.
-
- Aside from its unfortunate tendency to substitute for coal and oil
- burning, nuclear power is fairly neutral. This reflects my personal
- viewpoint that the nuclear economy is unlikely to result in
- significantly poisoning the environment over time. Being anti-
- nuclear is the appropriate Carbonist viewpoint no matter what your
- feelings about the safety of nuclear power. Nuclear safety is a
- non-issue for Carbonists.
-
- - Natural gas is not good, although it is not as bad as hydroelectric
- power (it does add small amounts of certain greenhouse gases to the
- atmosphere.) In most cases, however, natural gas substitutes for
- the significantly more beneficial practices of burning coal or oil,
- and so should be avoided.
-
- - Air pollution is good, particularly when it kills large areas
- of forest (Central Europe, California, etc.) These dead trees
- are far more likely to end up rotting and burning (and hence
- contributing to atmospheric CO2) than to end up in the ground.
-
-
- The Longer Term and the Meaning of Life
-
-
- A short term consequence of the restoration of a proper CO2 balance
- to the atmosphere will be a radical drop in the number of species
- within the Gaian system. This holocaust will be caused by the
- inability of most species to adapt to the rapid shift in climate,
- non-CO2 pollution occurring as a side effect of CO2 boosting, and
- related effects.
-
- The loss of speciation might well approach the worst of the dinosaur
- killer episodes in scope - perhaps 75% or more of Gaia's individual
- species will disappear in a period of only a few centuries.
-
- In the longer term, what of it? It's happened before, and it will
- happen again. The Gaian system has a proven ability to recover
- from loss of speciation. The destruction of 75% of Gaia's species
- is a routine event of no consequence; the impending White Earth
- Catastrophy offers the prospect of the death of Gaia itself - a
- multibillion-year-old organism of unimaginable richness and variety.
-
- Finally, it is worth noting that Carbonism speaks directly to the
- fundamental questions of human existence in a way that is both simple
- and profound. Carbonism holds that neither individual human life
- nor any achievement of humanity, other than the liberation of free
- carbon, has any significance whatsoever. Only the collective
- behavior of the human species is significant to Gaia, and in a
- few centuries (when the carbon balance has been restored) Gaia's
- need for humanity will be at an end.
