Geoengineering a Biosphere: Stupid, Dangerous and Doomed to Failure

Geoengineering is stupid, dangerous and doomed to failureSerious consideration is being given to the mad proposition of engineering the biosphere as a solution to climate change [ark]. Technological pseudo-scientific proposals for humans to engineer atmospheric processes are dubbed "geoengineering" [search] and generally seek to either reflect solar radiation or absorb greenhouse gases. They include such shortsighted, ill-conceived and risky ideas as mass release of aerosols into the atmosphere, fertilizing oceans with iron, and others, including my personal favorite, stationing mirrors above the Earth. Given the complexity of the Earth System, almost certain unintended consequences and the risk of doing immense further damage to global ecology; geo-engineering amounts to ecological vandalism.

Geoengineering is indicative of both humanity's ignorance and laziness when confronted with tremendous challenges of their own making such as climate change. Donít try to change society to massively reduce emissions, donít sacrifice or give up anything, donít try to change the government through protest or revolution. Instead, take a craps shoot and bet the whole planet that you can engineer the biosphere. This "Plan B" comes as there have been little serious efforts at a "Plan A". What of using all resources at our disposal -- including politically engaged ecologists and other Earth scientists -- to conserve energy, reduce emissions and pursue renewable alternatives? Have we really, fully tried that yet? We are unable to control even most invasive species, for example getting zebra mussels out of the Great Lakes. Yet now humanity is going to be responsible for engineering a livable biosphere forever?

Throbgoblins International: Cantankerous Frank, by Marc Roberts

To seek to engineer a biosphere -- something given freely for billions of years by Gaia, which still exists and operates, and has tremendous regenerative powers -- is the ultimate in hubris. Geoengineering is the equivalent of throwing a wrench at a broken grandfather clock in the hope that by smashing through its natural workings some good may come. There is huge potential for unforeseen consequences. What if some major ocean current or atmospheric oscillation shuts down or changes to a completely different state, as will almost certainly be the case? What will become of terrestrial ecosystems including forests, and water availability, as climate conditions shift in unknown, unforeseen and almost certainly unstable manners?

Illustrious scientists proposing such ecologically bereft madness [ark] are arrogant, and exemplify everything wrong with atomistic science and the ivory tower. Shame on any scientist not working on scientific rationale for, and otherwise supporting, perfectly sufficient and attainable solutions to climate change such as ending the use of coal and ancient forest logging. To instead propose engineering the biosphere -- something that ecological complexity and human imperfections strongly suggest can never be achieved -- reserves these masters of the universe a special place in ecological hell. Giving up on Earth's natural regenerative powers and humanity's ability to transform itself, to offer ecocidal, desperate plans for a one off gamble that almost certainly guarantees planetary extinction, is monstrous and evil exemplar.

No one has the right to propose such dangerous actions for our shared Earth, stymieing real solutions with pie-in-the-sky techno-fixes, and threatening with one master-stroke to ensure the destruction of being. Our ancestors waged revolution over the price of tea and for the principle of liberty. Today we are hard pressed to get our asses off the lazy-boy to fight for continued air, water and land for our children -- preferring instead Star Trekesque fantasies that allow us to continue our ecosystem destroying life of illusory comfort. Earth's biosphere cannot be engineered, efforts to do so will destroy her, and only personal and social transformation can save us now.


"What if some major ocean current or atmospheric oscillation shuts down or changes to a completely different state, as will almost certainly be the case?"

why is that almost certainly the case, is the author not being equally arrogent by presuming to know what gaia would do?

Well either arrogance or ignorance or a combination of both has got us to the point where experts in climate science are now debating if it is too late.

Humans have attempted a humungous geoengineering and landed all life in a dangerous state where death is a likely outcome for much of life through flooding the atmosphere with greenhouse gases.

GAIA's describer, Lovelock, has proposed huge tubes in the ocean to sink carbon rich warm water to the depths, a replication of the ocean circulation that is one regulator of the climate.

If this draws up low carbon cold water to increase the rate of carbon consumption by ocean life how many will we need to draw the CO2 down from 384ppmv and thus to stabilize the climate if we continue to emit CO2 at ever increasing rates by burning killer coal and poison oil and gas.

Is it a mistake to replicate nature by geoengineering?. Here I am discounting the mirrors as a space industry grab for money.

And getting such a system to work when we could simply fund energy efficiency and currently proved alternatives whilst developing new ones with the money spent on any of these geoengineering projects makes one wonder what the proponents know about the future.

Copenhagen in 2009 will determine if the world grasps the importanc of strong and immediate action to reduce CHG emissions.

Anything like Australia's business as usual target of a 5% reduction by 2020 will ensure that the danger of runaway climate instability, that scientist are now debating, will be assured.

Trying to stabilize a system in chaos with geoengineering will be the actions of desperation, the results unknown as other tipping points, if they have been crossed may require us to return to a much lower CO2 level, [perhaps as low as that of before the industrial revolution of 272ppmv] to stop those other gases released from nature.

And still we have to change our behavior.

Geoengineering without the evidence it will be effective and is absolutely necessary seems like a sidetrack to action we need to take now.

The dream phase is over, the cliamte has been changed to one of less stability and we must act with effective and timely comprehensive reductions in emissions now.

Per this part of Jason Moody's comment:" [I]s the author not being equally arrogent by presuming to know what gaia would do?"

Nowhere in Dr. Barry's essay did I see him say anything about exactly what the new climate state would be. Quoting Dr Barry, "What if some major ocean current or atmospheric oscillation shuts down or changes to a completely different state, as will almost certainly be the case?"

It makes no sense that the climate will stay the same when energy retention and energy transfer changes. Also, atmospheric chemistry changes are occurring in many well documented ways. It is also "beaten into the ground" documented that earth's climate has been different in the past and responds in a buffered way to these changes.

Let's say for experimental purposes that the climate of the earth can exist in one billion ways exactly. So, take one billion pennies and throw them in a pile to represent the one billion ways the earth's climate can exist. Now trade one of those pennies for a marked penny and stir the pennies well. Now picking a random penny, pick out the marked penny on the first try! Climate change is likely like that. We will have something different than what we had.

Also, hat I mean by "buffered" is like a light switch. It takes energy to turn it on or off. When the switch is changed to a new position it then also takes energy to change it back to the old position. Also when the switch is changed it does not respond immediately. The light says on until the filament cools and the light doesn't come on until the filament heats up, although it may seem to a casual observer that the change is instantaneous.
In other words, after a climate switch is thrown it takes some time for us to see the new state and recognize it. Once we do recognize a new state, it then takes energy to return to the old state if in fact that is even possible.(Consider the billion pennies!) I urge you to think about the consequences of those concepts.

Dr. Barry is correct...more of the same techno-meddling will not cure the disease caused by human technology run amok. The only way out is a complete change of paragdigm to a truly wholistic and organic life-centered life style. Gaia is a vast interconnected web of relationship, and by putting up mirrors, or dumping iron in the oceans, or any such "cure" we are going to break the web somewhere else in our short sighted attempts. We are like the addict, who rationalizes they can continue to use their drug if they counter it with some other behavior, etc. We must immediately halt our consumption of the world if their is any hope. The disease of the planet is can we mutate to a non-destructive form?

What we need is serious behavior modification!! Reduce by say 80% all household household consumption, taxing both individuals and greedy corporations, shut down fossil fueled transportation and power plants, shut down cement, steel and aluminum production. UN enforced population control. Eliminate deforestation by taxing with UN monitoring and enforcement (call it the UN Deforestation Admininstration, UNDA) especially Indonesia, Brazil, Malaysia, Russia, Philippines, Turkey and other major "land use problem countries" (representing around ~15% of total CO2e emissions). Close down international trade and leisure travel. This is just a "for starters."

Hi, Nature systems tend to a state of equilibrium, and climate isn't diferent, the problem is that human activity change the ins & outs of the equation, so that the system must rearrange...
We have already interfere with Nature in the wrong way, now it's time we interfere the right way, not permanently but until we strongly develop alternatives to fossil fuels and reach a sustainable may seems utopian but it worth a try.

My personal favourite in the "let's just do it even though we have no idea what will happen" category is Professor Tim Flannery's suggestion that sulphur be added to the atmosphere - such as by adding it to airplane fuel. Refer,23599,23724412-2,00.html

Greening Infrastructure: How engineering can protect ecosystems and ensure livelihoods. Innovative engineering and water management techniques are being employed to restore environmental flows on a permanent basis. At the same time, the economic benefits for which these river systems were initially developed are retained. However, can these approaches really restore rivers and get all sides to find a common solution? These are some of the discussions during the 5th World Water Forum, held between 16 and 22 March.

These Political Processes will not stop at he 5th World Water Forum. Their results will not only be used as a foundation for the 6th World Water Forum, but will also actively engage other international dialogues such as the G8, UN-CSD or UNFCCC. These meetings, and the results of the 5th World Water Forum, will raise the priority of water management strategies and actions on the international agenda.

The World Water Forum is the worldís premier event on water. It gathers over 15 000 participants from around the world to bring concrete solutions to the world's water challenges. A stepping stone towards global collaboration on water problems, the Forum offers the water community and policy-and-decision- makers from all over the world the unique opportunity to come together to create links, debate and attempts to find solutions to achieve water security.

The World Water Forum is organized every three years as a joint venture between the World Water Council and the government of the host country. After previous Forums in Morocco (1997), the Netherlands (2000), Japan (2003) and Mexico (2006), the 5th World Water Forum will be held in Istanbul, Turkey in March 2009. Get involved!

Here's a perfect example of how human meddling has unintended consequences:

It's a complicated web of relationship...and as we try to engineer the planet...we'll only make it worse...

I do so totally agree with Dr. Barry's analysis of geoengineering that I hardly have anything to add. In agreement though I would like to say that Who do we think we are? Do we possibly think that we can adjust the earth better than the earth can adjust itself? Do we think that even the absolute smartest scientists know every detail of how the scenario could play out? We've gotten ourselves into this mess by thinking we knew what we were doing. We need to get back to some old fashioned basics of how to live with respect for the earth. We have to stop being selfish and wasteful and appreciate what we have. The earth can live without us but we cannot live without the earth.

I'm shocked to see so called "environmentalist" shun good ideas, like promoting electric cars, in favor of bad ideas, like seeding our skys with dust, or clouds of barium, in an effort to increase the earth Albedo, and reflect a portion of the sun's rays back into if we know for sure that our world will be a better place with less sunlight, and as if sunlight was a bad thing, and perhaps the major culprit in Global Warming. How quickly we give up on conservation. The most shocking part of these proposals, and I've read alot of them, is the major selling factor...that it's cheaper. Geo engineering is cheaper, so therefore it must be better.
I read a proposal by a leading scientist in favor of Geo Engineering, and his strongest argument for it was that it would "allow a consumptive citizenry continue to consume, and allow an ambitious elite to continue to profit of that consumption" as if that was a situation we need to preserve, at all costs. I think about the "costs" of moving towards more efficient transportation, or electric cars and trains, more efficient electrical generation, and other conservation and wonder...who's funding these studies? We can deal with Global Warming, but only in a manner that permits the unfettered use of polluting vehicles. 75% of GHG come from personal vehicles...if we had electric cars, our dependence on foriegn oil would cease. We'd use 85% less oil! Whats' more, we'd cut CO2 emmissions by 80%. I'd say that's a pretty good start..bigger than any other plan, and much bigger results than any Geo-engineering idea. It won't happen because the big powers get their power from the sale of Oil. So don't expect to see a bunch of all electric cars anytime soon. Expect to see planes leaving big trails of dirty soot, or wispy white plumes of barium smoke in the sky. Expect to see alot less sun, and expect to hear alot of really technical sounding reasons why this is good. What a joke.

I have been watching the sky for about 6 years now. I travel from Northern Indiana to Central West Virginia several times a year so I watch them in both states as well as Ohio. On several occasions I have counted 17 planes at one time, always making the same trails. I have several photos of this and they all show the same patterns in the sky. When I speak with most people about it they think it is normal but I beg to differ. When I see a passenger jet it leaves a trail that dissapates in seconds, the planes I am talking about leave out immision smoke that does not dissapate instead it forms what I can only describe as fingers that eventually reach another line of smoke and within a very short time the sky that was a beautiful clear blue was then covered in clouds. Dont take my word for it,,look up and watch for yourself.
By the way, when i travel i have to take the amtrak because there are no major airports here for at least a 100 mile radius.
