Every study that has used a reasonable metric of climate damage and a 'reasonable' amount of deflection of sunlight has concluded that climate overall is brought much closer back to the pre-industrial state but that you are left with increased CO2-fertilization.

The only study done to date explicitly focusing on crop yields has concluded that crop yields would likely go up and not down. 

See, for examples:  


Also, Kate Ricke's work has concluded that for most reasonable climate change metrics, if any party acted in their own self-interest every party would be better off than if no party had acted.  http://www.nature.com/ngeo/journal/v3/n8/full/ngeo915.html

We have made YouTube videos about some of these studies:


This "threatens food supply of billions" stuff is completely unsupported by any rigorous analysis whatsoever.  If anyone's food supply is threatened, it will be a result of institutional failures associated with food distribution, not because of lack of food supply.

It's worth noting that the modeling result of a diminished monsoon isn't a highly reliable prediction. 

Also, the monsoon is not in any way optimal for agriculture or anything else. The biggest damage it causes is through flooding, ie, too much rain in a short while. Having been through some of them, I'd favor a lesser such storm.

Well, again, there are many reasons to be concerned about geoengineering as a solution or response even to catastrophic outcomes, including those with a reasonable risk, “however small.” The “however smallness” of the risk mostly serves to defeat the argument that geoengineering ought to be pursued on grounds that we will be averting catastrophe. I do not follow how a GE technology, with "however small" and reasonable risk and one which is capable of responding to an environmental catastrohy, is defeated by its bignin nature. There are many courses of action that carry risks of catastrophe, however small—genetic modification, CERN research, nuclear testing, military escalation, and even geoengineering itself. Ought we to take extraordinary steps to pursue these projects, or to avoid pursuing them, given that the threat of catastrophe is real, though the risk small? Clearly, the likelihood of the outcome matters, and it will not suffice to say that any risk, however small, authorizes geoengineering. This seems to be nothing more than a personal view of the risk value. I personaly believe that the Arctic Methane Risk as being a vary high order of thing(s) to worry about. You seem to view the risk of a tipping point as something which has a low probability and will go away if we paint our roofs white. Unfortunatly, there is little consensious as to the true level of risk and so there is little clearity as to the strenght of needed action. Until we have a better understanding of the true risk level, we only have personal views. It is not defensable to put such personal views out as a basis for ethical authority. And, I am as guilty on that count as many other are.  

No. It’s an counterfactual conditional. If it’s the case, then… I personally don’t believe the risk is small.

A similar concern applies even to cases of “significant risk.” In the case of geoengineering, the significant risk is only a ceteris paribus risk. Fortunately for us, everything is not ceteris paribus. The future is not only uncertain, but also indeterminate. It is not as though we have geoengineering and only geoengineering as options at our disposal. We have many options, including aggressive mitigation, aggressive adaptation, and even aggressive omission (just rolling the dice and allowing the significant risk of catastrophe to play out). Theoreticaly, these are all forms of GE. In the extream case, if we "roll the dice" and allow the possability of a tipping point to just play out, we will simply be GE the planet (perfectly for) bacteria and algae. Little more will be on this planet. Why pursue the most dramatic and totalizing course of action when there are so many other options? We don’t have an argument for choosing the most dramatic and totalizing course of action. Therefore, the position can’t be defended on grounds either that there is even a “significant” risk. Is this (do every thing but GE position) not just as much a 'dramatic and totalizing course of action' as geoengineering? Also, I can not understand how the potential extenction of most life forms on this planet, through a tipping point, is not grounds for defense of GE developement and eventual deployment.

If you think these are all forms of GE, then you’ve got a cavernously wide view of GE. If you have such a wide view of GE, then there is no ethical question about GE. It’s either permissible or obligatory or forbidden or a foregone conclusion (depending on your view of such actions). In other words, you’re begging the question. Ought we to geoengineer? Your answer to this question cannot be: geoengineering is permissible because everything we do is geoengineering.

We also oughtn’t to assume that just because some course of action is authorized that therefore all courses of action are thereby authorized. Just because maybe some geoengineering technology may be permissible, for instance, does not and cannot authorize all forms of geoengineering. More concretely and for example, just because it may be permissible to paint our roofs and highways white, doesn’t mean that it is therefore also permissible to shoot aerosols into the troposphere to achieve the same effect. These are different technologies, with different deployment features, and must be assessed differently. That is fully understood by most folks researching this field of thought.

Doesn’t sound like it to me.

Sorry to disappoint, but you’ll need stronger arguments than these if you want to say either (a) that it’s permissible or, more strongly, (b) that it’s obligatory. I enjoyed reading your personal opinion.

Dear John—It seems to me that trying to make such clean distinctions as ethical or unethical is neither going to be possible nor to be an approach that attracts adherents. We are all in quite compromised positions given our present and past reliance on fossil fuel use and casting aspersions is not going to be seen as an approach that is appreciated or effective, especially in that it will be imposing significant requirements (and possibly other unintended impacts) on, particularly, future generations. What scientists try to do, to the limits of our abilities and capabilities, is to illuminate the situation being faced and the implications and consequences of possible choices. There can be many aspects of determining a course of action (or inaction) other than the scientific aspects (and at this point, the scientific and technological aspects alone are still in flux), and the discussions on ethics and governance (and more) are shining light on many other aspects to be considered. While we will never have perfect knowledge on any of this, it seems to me it is going to be much more effective helping to inform others by refining the understanding and uncertainties than darkly characterizing others who are similarly concerned about the seriousness of our predicament and also trying to work toward promoting a better future for us all.

Hi all,
 
I'd like to support an excellent posting earlier on this thread, from which I'd like to quote:
 
"The risk, however small, of a Permian scale catastrophe as a result of anthropogenic climate change, and the potential need for geoengineering to avert it, illustrates that geoengineering may in fact be the biggest ethical issue ever, opening the existential problem of human planetary survival."
 
I don't see how anybody could argue with this.  Furthermore there is a significant risk that a catastrophe on this scale could happen as a result of Arctic warming, sea ice collapse and methane release.  Thus those who oppose geoengineering to cool the Arctic, save the sea ice and dampen the methane emissions have to consider whether they are taking a ethical position.
Cheers,
 
John

Dear Andrew—As I recall, at least one of the Hadley scenarios for just GHGs had Amazonian vegetation dying away, so comparative evaluation could be very interesting—we do have to remember the decision is between GHG without GE (and there are multiple scenarios for this) and GHG with GE (and there are many GE possibilities as well, at least some of which can be tuned to minimize at least some types of impacts—making such choices, of course, will not be without controversy, some real and likely some speculative and inflammatory, etc.).

It's the imbalance of polar temperatures which is a cause for concern - a geoengineered arctic on its own. The result is a potential geographic shift of the ITCZ which could have dramatic effects on regional vegetation.

If we are to engineer only the arctic we need to be sure this won't mess up other parts of the climate system.

I hope Mike's model run will involve a range of forcings up to very large interventions, to detect any potential tipping points.

Putting the output through a vegetation model will hopefully give us some really useful info.

John Shepherd cautioned me that there's a risk that Arctic geoengineering could move the ITCZ, and hence the monsoon.
 

If we're even considering doing this at any point in the next couple of decades, we should IMO be pushing modelling studies right away. The consequences of inadvertently affecting the monsoon are very serious indeed, and we need to accurately model the teleconnections before making actionable proposals.
 

My understanding is that this needs a high res GCM model to resolve this effect.  I hope a group can run this.

 I’ve been off-line for most of this discussion, but let me offer a couple of comments regarding tropospheric sulfate. The major health and environmental impacts of sulfate and the SO2 emissions been that, because the SO2 is a by product of coal combustion, the emission of SO2 and deposition of sulfate have been generally in the most populated regions of the world (North Atlantic basin through much of the 20th century, and now, presumably, mainly eastern and southern Asia). In a geoengineering application, limited scientific results suggest that it would be much more effective to be creating the sulfate layer out over the dark ocean, in relatively clean areas to enhance cloud brightening, and in low latitudes to get maximum solar exposure—and it would make no sense to put out all the other byproducts of coal combustion that may actually be the cause of the worst health impacts. Thus, assuming one could technically emit the SO2 over remote Pacific and Indian ocean areas in ways that would create larger areas with lower amounts of sulfate to get a similar or even greater cooling effect, the ethical (and governance) issues concern how might one make the tradeoffs of perhaps significantly reduced climate impacts for billions, but, quite possibly, a different mix of impacts (some less, some more) for millions.
 
 My suggestions to use sulfate in the Arctic troposphere during the Arctic sunlit season only raise similar issues—though in this case those in the Arctic presumably get very significant benefits in that one would be trying to preserve the present or slightly cooler climate while experiencing some impacts (for several reasons quite possibly lower health impacts than caused by past SO2 emissions) with key potential benefits of slowing or countering permafrost thawing (so reducing global warming) and ice sheet mass loss (so reducing sea level rise) with likely some impacts on precipitation systems that are good for some and detrimental to others, etc. Again, very challenging governance and ethical aspects (not to mention public education challenges to have an informed discussion).
 
 And then there is the potential that some other suitable substance could be generated (e.g., sea salt CCN) that would presumably limit the health impacts (although this may well not be the dominant impact to be considered, there are economic considerations, and lots more). And there may be particular operational considerations that can minimize some types of impacts, etc.
 
 With so much (and more) to be considered, it seems to me there is a very significant need to be augmenting scientific thinking about all of this—indeed, the engineering and scientific aspects might well be the least challenging aspects.

 Hi Oliver,
  
 I attended the Planet Under Pressure conference, for the session on geoengineering governance.  A cynic would regard most of the speakers as people who had found a nice subject for academic study, and were not particularly interested in whether geoengineering was actually required!  But let me move on from cynicism.
  
 I take John Gorman's point that the problem we face is essentially an engineering problem, quoting the economist Robert Samuelson who said:
  
 "The trouble with the global warming debate is that it has become a moral crusade when it's really an engineering problem. The inconvenient truth is that if we don't solve the engineering problem, we're helpless."
  
 As an engineer as well as a scientist, I am able see the Earth System as a piece of engineering, where the mechanism controlling stability (especially of temperature and the carbon cycle) has been damaged and requires repair.  Certain parts of the system are critically damaged and require repair immediately before the system collapses into a new state, inconducive to the continuation of civilisation as we know it.  In this situation, not to intervene would be suicidal, and therefore there is a moral imperative to act.
  
 Now, I agree with Michael Hayes's argument that that any action to affect the Earth System, whether deliberate or inadvertent, should be considered geoengineering.  For me the question of morality of some particular geoengineering technique or measure, is whether it is helping to repair (or allow repair of) the Earth System or not.
  
 May I now take an example of where a 'good/ethical measure' from one point of view is a 'bad/unethical measure' from another point of view.  This is sulphate aerosol in the troposphere.  This has been countering the global warming of greenhouse gases by up to 75% during the past century, until there was a determined effort to reduce sulphur 'pollution' in the 80s and 90s.  This effort continues with an effort to further reduce tropospheric sulphur by removing the sulphur from the 'bunker fuel' used by ships.  It has been estimated that ships have contributed a negative forcing (i.e. a global cooling) of up to 0.6 Watts/m-2.
  
 So from one point of view - the pollution point of view, which prevails today - the removal of sulphur from bunker fuel is a good thing.  But if one considers how seriously damaged the Earth System has become, especially with the sea ice retreat in the Arctic, removal of sulphur is close to suicidal, and definitely bad/unethical.
  
 Leaving sulphur in ship's fuel is not going to save the Arctic sea ice, but will definitely help.  If you agree with the argument that saving the sea ice is necessary to reduce the risk of methane feedback (i.e. necessary to defuse the methane time-bomb) then removing sulphur from ship's fuel is not sensible.
  
 The case for SRM geoengineering to cool the Arctic is much clearer.  Without some rapid cooling action to save the Arctic sea ice, the Arctic warming will accelerate, methane feedback will almost inevitably gain traction, and we could be in for run-away global warming - definitely suicidal.
  
 So SRM geoengineering has to be part of the solution of the engineering problem, in the case of the Arctic sea ice.  Not to geoengineer would be suicidal and therefore immoral.

Nevertheless, we might surprise ourselves and our plebeian problems might in fact induce innovation within the helping discipline.

 Admittedly, I looked at your first paper only, which discussed 'moral hazard'. It does seem to me useful to examine what is meant by this term, and how people are using it differently in the geoengineering context.
 
 It is good to know when we have a disagreement whether that disagreement is a difference in our understanding of the facts, a difference in our values, or whether it is a difference in how we are applying words. (And also if it is possible to have disagreements that somehow sit between these categories -- are there clear boundaries between matters language, values, and fact?)
 
 Insofar as philosophers are able to help us disentangle differences in use of language from differences in value judgments and differences in our understanding of the facts, this is a useful enterprise.  More often than not, these things are muddied in discussion. It would be useful if everyone, when we have a disagreement, would make a greater effort to identify the source and nature of the disagreement.
 
 =======================
 
 On matters of language,  I am with Humpty Dumpty. I am usually willing to defer to anyone's usage, if they can provide a reasonably clear definition explaining how they are using terms. On the other hand, I am very much with Hume in wanting to clearly distinguish between is and ought, while recognizing that much of language embodies both fact and value.
 
 Think of the use of a term like 'enhances' that implicitly contains a value judgment -- if we assert that 'ocean fertilization increases carbon export' are we also asserting that 'ocean fertilization enhances carbon export'? Can I agree we the first assertion and disagree with the latter?  Sometimes we don't understand when we are making a factual statement and when we are implicitly presenting a value judgment.
 
 ========================
 
 “When I use a word,” Humpty Dumpty said, in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.”
 “The question is,” said Alice, “whether you can make words mean so many different things.”
 “The question is,” said Humpty Dumpty, “which is to be master      that’s all.”

I guess a philosopher should probably pipe in here.
 
  
 
 I work a fair bit on ethics and geoengineering. Most of what I've been doing has been oriented around getting a clearer sense of what problem geoengineering is supposedly a response to. There's a prevailing assumption, for instance, that we well understand the problem with climate change, but I think this is far from clear. Supposedly, the problem with climate change is that the climate will change, and presumably this will be a change for the worse. I don't disagree that the change will be for the worse, but that it will be worse simpliciter doesn’t strike me as the core problem. Many things in the world change for the worse, and only sometimes do we respond to them. The question of geoengineering, and the variety associated technologies, can help us get a grip on the nature of the climate change problem. So that’s one way in which geoengineering has interest philosophically: by shedding light on the problem that many of us are keen to address and helping us understand the nature of our obligations to address this problem.
 
  
 
 Another way in which ethics and geoengineering are philosophically interesting is in a clinical sense: we need to ask what sorts of things we’re permitted or obligated to do; and what sorts of things we’re restricted from doing. Just as a bioethicist dissects the sundry questions associated with health, technology, and medicine, so too can ethicists do the same with geoengineering. There are many related questions about the permissibility of one technology over another, as clearly some technologies will demand more of some, or perhaps burden others, in ways that are unacceptably unfair.  
 
  
 
 Beyond the forward-looking clinical ethical questions, there are also questions related to definition and the nature of geoengineering. For instance, I think the distinction between SRM and CDR is falsely concrete, and that instead we should distinguish according to whether geoengineering is an attempt to remediate (that is, to draw down our carbon and GHG contributions, as well as our bad land-use decisions, by way of cleaning up our messes) versus an attempt to steer (that is, to avoid anticipated bad consequences from our prior actions). To me, at least, this distinction helps us understand some relatively powerful intuitions that we may have, for instance, that air capture technologies and reforestation practices are nowhere near as worrisome as stratospheric injection technologies and ocean fertilization proposals.
 
  
 
 As to Ken's initial inquiry, it's hard to say, generally, what philosophers are doing. It is true that in one respect there's nothing new under the sun, that all hitherto philosophy is just a series of footnotes to Plato, but what most of professional philosophers take themselves to be doing is gaining a bit more clarity and insight on current and ancient problems than otherwise might be gained simply by picking up the classic texts. In the case of geoengineering, there's a lot of work to be done that may help us get to a better place with a more intelligent discourse.

 I think I simply use the word 'philosophy' different than most modern philosophers.
 
  
 
 Just as I think of mathematicians developing new mathematical theory while the rest of us apply existing theory to do calculations aimed at solving real world pproblems, I thought philosophers were developing new general theory and the rest of were applying this theory in our own moral calculations.
 
  
 
 It seems to me that alot of what is beig called 'philosphy' is people trying to do moral calculations.
 
  
 
 Often math progresses because a calculational need arises for which there is no existig relevant mathematical theory and this spurs the mathematicians to develop new theory  
 
  
 
 It seems to me that the ethics of decision making when decisions affect others not involved in the decision making is a problem as old as the hills.
 
  
 
 I just don't see how this itch is going to need a scratch of a different kind.  Aren't existig types of scratches are sufficient? I will be suprised if geoengineering will really be an irritant that can spur  philosophical innovation. Not impossible, but I am dubious.
 
  
 
 In contrast, I do see how  neuroscience can perhaps act a an tch that promotes new types if philosophical scratches.

The people least likely to be affected directly by changes to the
monsoon and ITCZ seem most comfortable in commenting on it. I hope
they are also interested in the opinions of the small farmer in
Western India or the goatherd in Mali.

A complex set of factors goes into the agricultural, economic and
social impacts of the monsoon and its variability -- whether real or
perceived. See, for example, the article on the Indian Monsoon here:
http://www.ias.ac.in/resonance/December2008.htm. Some of the
statements about the ITCZ and monsoon in this thread do not seem to
fully acknowledge that complexity.

From the abstracts of two of the papers Ken cites below:
"Nevertheless, possible yield losses on the local scale as well as
known and unknown side effects and risks associated with
geoengineering indicate that the most certain way to reduce climate
risks to global food security is to reduce emissions of greenhouse
gases." And, "Regional diversity in the response to different levels
of solar-radiation management could make consensus about the optimal
level of geoengineering difficult, if not impossible, to achieve."

What happens at the regional and local scales -- besides a host of
other factors -- is important in determining whether the intended or
unintended consequences of geoengineeing could be labelled as positive
or negative. To their credit (and I presume to the credit of the
reviewers and editors), these papers provide a rather nuanced take on
the tough issues at stake. It would be good if our discussions on this
forum did that too, on a more regular basis.

PS - How can we assure ourselves that the same sorts of institutional
failures that can affect food supply will not affect the design and
execution of geoengineering schemes?

The lead author of one of the studies I mentioned is living and working in India (Govindasamy Bala), while a co-author of one of the other studies I mentioned (Long Cao) is now living and working in China.

Long Cao, Govindasamy Bala, and I may have the deepest climate modeling collaboration in the world spanning these countries. While I can only speak for myself, I think we all feel that climate science knows no national boundaries.

Ken

Whilst I broadly agree with you on the issue of food security under global geoengineering, I'm not sure that this carries to regional schemes. What has been proposed on this list, with some degree of serious consideration, is the regional geoengineering of the Arctic in isolation - with either direct sulphur or MCB approaches being used to effect this.

My understanding is that there has not, as yet, been a sufficient range of studies done which would allow us to address with confidence the food security situation resulting from this kind of intervention.  The threat to the food supply may come specifically from failures in the monsoon caused by a movement of the ITCZ, or perhaps from other, as yet unexplored teleconnections.

AFAIK, the studies which have been done to date do not exclude the possibility that a *regional* geoengineering scheme may indeed 'threaten the food supply of billions'.  Even if global food supply were to rise, distribution cannot be assured - especially to subsistence rural communities with no real infrastructure for food retail and distribution.  This is further exacerbated by the potentially sudden changes to weather which may happen as a result of AGW.  Can we really react to sudden droughts, etc. from a geopolitical point of view?

Even very temporary disruption to the food supply can kill many people rapidly.  The famine in E. Africa is testament to this.  Comparatively few people live in E. Africa, whereas a change to the productivity of Asian farming could be much more likely to cause a globally-significant famine.

I am not trying to be alarmist, but I personally wouldn't 'bet the farm' on there not being potentially dangerous disruption to the global food supply from regional geoengineering.  Maybe I'm just ignorant of the science, but my personal view remains that we need to more robustly model the climate teleconnections, vegetation changes and resulting supply-chain impacts before we can be confident that we've taken reasonable steps to exclude these risk.

Finally, I'd generally urge caution on over-reliance on modelling.  The loss of Arctic sea ice itself suggest that we have a poor general ability to model secondary climate effects

Andrew sums it up:

The alternative to modeling of course is experiment, built up in scale and intensity, and in the air.

Andrew—A couple of comments:

1. It may well be that it is limits in representing the forcings in the Arctic that are contributing to the actual meltback of sea ice being a bit more rapid than models have been simulating (and just to note that model representations of sea ice are improving, and discrepancy has, as I understand it, been going down). The forcings that are perhaps not being adequately represented include black carbon, reductions in sulfate loading due to reductions in SO2 emissions in North America and Europe/FSU, tropospheric ozone, etc.

2. While I wholeheartedly agree that we need a lot more modeling studies on this, I think you may be suffering from too much looking at Mercator projections of the world’s geography. Compared to the dynamics of the monsoons and hydrologic cycle, the Arctic is a pretty small region (e.g., Greenland is half the size of India, not near an order of magnitude bigger as appears on Mercator projections), which is why it might be possible to actually cause a change there. We do need to look at it closely, but, while the ITCZ seasonal cycling may be somewhat affected, Arctic interventions would not be shifting the solar input and its seasonal variations over most of the Earth and so ocean and land temperatures are not greatly changed, and it would be quite surprising if the hydrologic cycle were shifted so much as to be affecting billions of people, especially billions of people more than might be affected by unrestrained GHG warming.

Every study that has used a reasonable metric of climate damage and a 'reasonable' amount of deflection of sunlight has concluded that climate overall is brought much closer back to the pre-industrial state but that you are left with increased CO2-fertilization.

The only study done to date explicitly focusing on crop yields has concluded that crop yields would likely go up and not down. 

See, for examples:

http://dge.stanford.edu/labs/caldeiralab/Caldeira_research/BanWeiss_Caldeira.html 
http://dge.stanford.edu/labs/caldeiralab/Caldeira_research/Govindasamy_Thompson.html 

Also, Kate Ricke's work has concluded that for most reasonable climate change metrics, if any party acted in their own self-interest every party would be better off than if no party had acted.  http://www.nature.com/ngeo/journal/v3/n8/full/ngeo915.html

We have made YouTube videos about some of these studies:


This "threatens food supply of billions" stuff is completely unsupported by any rigorous analysis whatsoever.  If anyone's food supply is threatened, it will be a result of institutional failures associated with food distribution, not because of lack of food supply.

It's worth noting that the modeling result of a diminished monsoon isn't a highly reliable prediction. 

Also, the monsoon is not in any way optimal for agriculture or anything else. The biggest damage it causes is through flooding, ie, too much rain in a short while. Having been through some of them, I'd favor a lesser such storm.

Well, again, there are many reasons to be concerned about geoengineering as a solution or response even to catastrophic outcomes, including those with a reasonable risk, “however small.” The “however smallness” of the risk mostly serves to defeat the argument that geoengineering ought to be pursued on grounds that we will be averting catastrophe. I do not follow how a GE technology, with "however small" and reasonable risk and one which is capable of responding to an environmental catastrohy, is defeated by its bignin nature. There are many courses of action that carry risks of catastrophe, however small—genetic modification, CERN research, nuclear testing, military escalation, and even geoengineering itself. Ought we to take extraordinary steps to pursue these projects, or to avoid pursuing them, given that the threat of catastrophe is real, though the risk small? Clearly, the likelihood of the outcome matters, and it will not suffice to say that any risk, however small, authorizes geoengineering. This seems to be nothing more than a personal view of the risk value. I personaly believe that the Arctic Methane Risk as being a vary high order of thing(s) to worry about. You seem to view the risk of a tipping point as something which has a low probability and will go away if we paint our roofs white. Unfortunatly, there is little consensious as to the true level of risk and so there is little clearity as to the strenght of needed action. Until we have a better understanding of the true risk level, we only have personal views. It is not defensable to put such personal views out as a basis for ethical authority. And, I am as guilty on that count as many other are.  
No. It’s an counterfactual conditional. If it’s the case, then… I personally don’t believe the risk is small.

A similar concern applies even to cases of “significant risk.” In the case of geoengineering, the significant risk is only a ceteris paribus risk. Fortunately for us, everything is not ceteris paribus. The future is not only uncertain, but also indeterminate. It is not as though we have geoengineering and only geoengineering as options at our disposal. We have many options, including aggressive mitigation, aggressive adaptation, and even aggressive omission (just rolling the dice and allowing the significant risk of catastrophe to play out). Theoreticaly, these are all forms of GE. In the extream case, if we "roll the dice" and allow the possability of a tipping point to just play out, we will simply be GE the planet (perfectly for) bacteria and algae. Little more will be on this planet. Why pursue the most dramatic and totalizing course of action when there are so many other options? We don’t have an argument for choosing the most dramatic and totalizing course of action. Therefore, the position can’t be defended on grounds either that there is even a “significant” risk. Is this (do every thing but GE position) not just as much a 'dramatic and totalizing course of action' as geoengineering? Also, I can not understand how the potential extenction of most life forms on this planet, through a tipping point, is not grounds for defense of GE developement and eventual deployment.
If you think these are all forms of GE, then you’ve got a cavernously wide view of GE. If you have such a wide view of GE, then there is no ethical question about GE. It’s either permissible or obligatory or forbidden or a foregone conclusion (depending on your view of such actions). In other words, you’re begging the question. Ought we to geoengineer? Your answer to this question cannot be: geoengineering is permissible because everything we do is geoengineering.

We also oughtn’t to assume that just because some course of action is authorized that therefore all courses of action are thereby authorized. Just because maybe some geoengineering technology may be permissible, for instance, does not and cannot authorize all forms of geoengineering. More concretely and for example, just because it may be permissible to paint our roofs and highways white, doesn’t mean that it is therefore also permissible to shoot aerosols into the troposphere to achieve the same effect. These are different technologies, with different deployment features, and must be assessed differently. That is fully understood by most folks researching this field of thought.
Doesn’t sound like it to me.

Sorry to disappoint, but you’ll need stronger arguments than these if you want to say either (a) that it’s permissible or, more strongly, (b) that it’s obligatory. I enjoyed reading your personal opinion.

Dear John—It seems to me that trying to make such clean distinctions as ethical or unethical is neither going to be possible nor to be an approach that attracts adherents. We are all in quite compromised positions given our present and past reliance on fossil fuel use and casting aspersions is not going to be seen as an approach that is appreciated or effective, especially in that it will be imposing significant requirements (and possibly other unintended impacts) on, particularly, future generations. What scientists try to do, to the limits of our abilities and capabilities, is to illuminate the situation being faced and the implications and consequences of possible choices. There can be many aspects of determining a course of action (or inaction) other than the scientific aspects (and at this point, the scientific and technological aspects alone are still in flux), and the discussions on ethics and governance (and more) are shining light on many other aspects to be considered. While we will never have perfect knowledge on any of this, it seems to me it is going to be much more effective helping to inform others by refining the understanding and uncertainties than darkly characterizing others who are similarly concerned about the seriousness of our predicament and also trying to work toward promoting a better future for us all.

Hi all,
 
I'd like to support an excellent posting earlier on this thread, from which I'd like to quote:
 
"The risk, however small, of a Permian scale catastrophe as a result of anthropogenic climate change, and the potential need for geoengineering to avert it, illustrates that geoengineering may in fact be the biggest ethical issue ever, opening the existential problem of human planetary survival."
 
I don't see how anybody could argue with this.  Furthermore there is a significant risk that a catastrophe on this scale could happen as a result of Arctic warming, sea ice collapse and methane release.  Thus those who oppose geoengineering to cool the Arctic, save the sea ice and dampen the methane emissions have to consider whether they are taking a ethical position.
Cheers,
 
John

Dear Andrew—As I recall, at least one of the Hadley scenarios for just GHGs had Amazonian vegetation dying away, so comparative evaluation could be very interesting—we do have to remember the decision is between GHG without GE (and there are multiple scenarios for this) and GHG with GE (and there are many GE possibilities as well, at least some of which can be tuned to minimize at least some types of impacts—making such choices, of course, will not be without controversy, some real and likely some speculative and inflammatory, etc.).

It's the imbalance of polar temperatures which is a cause for concern - a geoengineered arctic on its own. The result is a potential geographic shift of the ITCZ which could have dramatic effects on regional vegetation.

If we are to engineer only the arctic we need to be sure this won't mess up other parts of the climate system.

I hope Mike's model run will involve a range of forcings up to very large interventions, to detect any potential tipping points.

Putting the output through a vegetation model will hopefully give us some really useful info.

 I think I simply use the word 'philosophy' different than most modern philosophers.
 
  
 
 Just as I think of mathematicians developing new mathematical theory while the rest of us apply existing theory to do calculations aimed at solving real world pproblems, I thought philosophers were developing new general theory and the rest of were applying this theory in our own moral calculations.
 
  
 
 It seems to me that alot of what is beig called 'philosphy' is people trying to do moral calculations.
 
  
 
 Often math progresses because a calculational need arises for which there is no existig relevant mathematical theory and this spurs the mathematicians to develop new theory  
 
  
 
 It seems to me that the ethics of decision making when decisions affect others not involved in the decision making is a problem as old as the hills.
 
  
 
 I just don't see how this itch is going to need a scratch of a different kind.  Aren't existig types of scratches are sufficient? I will be suprised if geoengineering will really be an irritant that can spur  philosophical innovation. Not impossible, but I am dubious.
 
  
 
 In contrast, I do see how  neuroscience can perhaps act a an tch that promotes new types if philosophical scratches.

Hi, Andrew -

In Ken's 'white paper' on arctic geoengineering, the quantity
of SO2 used was hardly larger than one single large US coal plant
(about 33% bigger than the largest US plants, I think).

I entirely agree that what you are bringing up should be looked into
thoroughly,
as too often things that have looked hopeful in the past have turned
out to have serious
problems upon closer examination, but saying that no study has
excluded such potential harm
(when no such study has yet been undertaken, isn't that right?)
doesn't really suggest that there's
any particular reason to expect that such harm is likely,
either......

All best,

Nathan
