2014-08-17 Thread Rau, Greg
Toby,
I regret I will not be at the meeting to learn more about the ethics of CDR. 
Presumably this refers to enhancement of existing, natural CDR which is already 
removing about 55% of our emissions, but which is immune from ethical 
considerations(?) Regardless of our actions, this natural CDR will eventually 
consume all of our CO2 and return air CO2 (and climate?) to pre-industrial 
levels, so what are the ethics here? In any case, I assume the ethics of CDR 
referred to really means the ethics of accelerated CDR.  Good to see that 
such activity and its ethics will be put in context of alternative actions as 
stated in the session description.

Dr.  Svoboda, list, and panelists

1.  Thanks for the alert on this 1.5 hour panel.   I hope that you 
and/or others can report back on any comparisons found for the ethics of CDR 
and SRM.

2.   Curiously, a major news item relative to biochar just came to my 
attention yesterday - a report (dated 30 July) by a market research firm on the 
nascent biochar industry.  See 
http://www.transparencymarketresearch.com/biochar-market.html .  I mention it 
only because the report is  unlikely to have been on the radar of this panel.

3.  My guess is that this is the only market projection for any 
geoengineering approach.  I can't comment on its validity since its cost (about 
as much as 5 tonnes of char) exceeds my interest level.  Without the benefit of 
reading any but the brief summary, I personally think it is on the conservative 
side.  I am not recommending this report - only reporting on its existence.

4.   However, I hope the panelists will factor in the report's 
rationale (a bit given at the above site), for the sales growth predicted for 
biochar, into how they compare the ethics of biochar (and competing CDR 
approaches) in comparison with the SRM approaches.  I am not saying that 
projected future sales should greatly influence discussion of biochar (and 
other CDR) ethics, but I do believe that the reasons for that projected growth 
(NOT involving CDR) should have importance in this panel's discussions.

5.  The websites of the six companies listed (Agri-Tech Producers, LLC, 
Biochar Products, Inc., Cool Planet Energy Systems Inc, Blackcarbon, Diacarbon 
Energy Inc and Genesis Industries) may also be of interest  (and two others I 
know are selling quite a bit are in the 175 companies they say are now 
considered part of the biochar industry).

Again - Prof.  Svoboda - thanks for this alert.  Best of luck with your panel.

2014-08-15 Thread J.L. Reynolds
Dear Tony (and all),

Thank you for your thoughts on my response. Based upon what you wrote here, it 
seems that we have more common ground than I initially thought. My purpose in 
bringing up the wide array of socially organized responses to other complex 
problems was to indicate that the challenges to compensation for harm from SRM 
often also apply to these other responses. What is supposed to follow is that, 
regarding socially organized responses in general, While these arrangements 
could be called ethically problematic, they constitute the very core of public 
policy and that such 'ethical uncertainty' generally neither raises questions 
of ethical permissibility and nor induces paralysis among policy makers in 
other domains such as the provision of public goods, compensation, and 
mitigation and adaptation in response to climate change. [This is not to imply 
that you called for paralysis, but such paralysis could be a reader's 
reasonable response to your ethical problematization of compensation for harm 
from SRM.] I also do not mean to imply that compensation for SRM harm can fall 
into only one of two categories: (1) completely novel, or (2) completely not 
novel. There are clearly points between. Yet I was struck by the fact that, to 
the large extent that these ethical challenges which you cited also apply in 
these other social responses, you limited your focus to compensation from SRM 
harm.

With best wishes,

Hi All,

Interesting discussion. First, regarding intention, much of what has been said 
above is helpful, and I would second Jesse's recommendation of David Morrow's 
paperhttp://www.tandfonline.com/doi/full/10.1080/21550085.2014.926056#.U-0WuWP6eyM
 on doing/allowing and double effect (full disclosure: David and I are 
coauthors on a separate project.)
I appreciate Jesse's commentary on Peter's and my paper (thanks!), and I wanted 
to address some of the points he raises. Jesse suggests that the main problem 
in our paper is that we treat the shortcomings of SRM and of compensation for 
its potential negative secondary effects as if they were sui generis. But to 
clarify, it is not our view that SRM compensation is a sui generis problem, nor 
do we state that it is in our paper. It may well be true that the ethical 
challenges faced by SRM compensation are already faced in other domains, such 
as socially organized responses to complex problems, other instances of 
compensation provision, and climate change (to take Jesse's examples).

Our claim was that providing compensation for SRM-related harm faces some 
difficult challenges. If Jesse is right, many or all of these same challenges 
arise in other domains, but he does not specify what is supposed to follow from 
this. Our argument is not undermined by the fact (if it is one) that there are 
parallels among these various domains, for the challenges to SRM compensation 
remain challenges even if they are not unique to SRM. Jesse writes that SRM 
might be especially complex, in large part of its global nature, but that does 
not make it entirely novel. We can agree with this, because we did not claim 
that SRM is entirely novel. Nonetheless, since the issue of SRM compensation is 
particularly complex, it is worth investigating whether we can disentangle the 
many issues involved and reduce uncertainty regarding them.

Jesse also suggests that we stack the deck against SRM, but I think this is 
due to a misunderstanding of what our paper aims to do. Although we noted 
throughout the paper that SRM could have many benefits, we did not emphasize 
these potential benefits because the issue under investigation was compensation 
provision for harms due to SRM. Of course, this focus would tend to emphasize 
potential harms, since our primary question was how such harms should be 
remunerated. Given that question, it would be odd to emphasize the potential 
benefits of SRM, although we certainly acknowledge them.

It is important to note that Peter and I were not addressing whether some form 
of SRM should be deployed in the future. As we wrote, We conclude that 
establishing a just SRM compensation system faces severe difficulties. This 
does not necessarily imply that SRM ought never to be deployed, as there might 
be satisfactory ways to resolve these difficulties. Furthermore, even if these 
difficulties are not fully surmounted, it does not necessarily follow

Dr. Svoboda's final sentence is not logically valid.  I hope some ethicist will 
challenge my (and many others) view that some forms of CDR are strongly 
positive forces at this time.

5.  I understand that every geoengineering/ethics paper cannot also 
include CDR.  But surely there must be someone interested in the geoengineering 
/climate/ethics arena who is also interested in the CDR side?  And willing to 
write on the topic - either with or without mentioning SRM?  There are many of 
us ready to help on specific approaches.  Caution - one can't write on CDR as a 
single approach, but there are probably some important ethical general 
statements about that grow of CDR approaches which we can agree are net 
positive good.

 Jim Hansen doesn't discuss SRM;  he has mainly talked about the

Re: [geo] Response to Svoboda and Irvine, J Reynolds

2014-08-14 Thread Toby Svoboda
Hi All,

Interesting discussion. First, regarding intention, much of what has been
said above is helpful, and I would second Jesse's recommendation of David
Morrow's paper
http://www.tandfonline.com/doi/full/10.1080/21550085.2014.926056#.U-0WuWP6eyM
on doing/allowing and double effect (full disclosure: David and I are
coauthors on a separate project.)

I appreciate Jesse's commentary on Peter's and my paper (thanks!), and I
wanted to address some of the points he raises. Jesse suggests that the
main problem in our paper is that we treat the shortcomings of SRM and of
compensation for its potential negative secondary effects as if they were
sui generis. But to clarify, it is not our view that SRM compensation is a
sui generis problem, nor do we state that it is in our paper. It may well
be true that the ethical challenges faced by SRM compensation are already
faced in other domains, such as socially organized responses to complex
problems, other instances of compensation provision, and climate change (to
take Jesse's examples).



Our claim was that providing compensation for SRM-related harm faces some
difficult challenges. If Jesse is right, many or all of these same
challenges arise in other domains, but he does not specify what is supposed
to follow from this. Our argument is not undermined by the fact (if it is
one) that there are parallels among these various domains, for the
challenges to SRM compensation remain challenges even if they are not
unique to SRM. Jesse writes that SRM might be especially complex, in large
part of its global nature, but that does not make it entirely novel. We
can agree with this, because we did not claim that SRM is entirely novel.
Nonetheless, since the issue of SRM compensation is particularly complex,
it is worth investigating whether we can disentangle the many issues
involved and reduce uncertainty regarding them.



Jesse also suggests that we stack the deck against SRM, but I think this
is due to a misunderstanding of what our paper aims to do. Although we
noted throughout the paper that SRM could have many benefits, we did not
emphasize these potential benefits because the issue under investigation
was compensation provision for harms due to SRM. Of course, this focus
would tend to emphasize potential harms, since our primary question was how
such harms should be remunerated. Given that question, it would be odd to
emphasize the potential benefits of SRM, although we certainly acknowledge
them.



It is important to note that Peter and I were not addressing whether some
form of SRM should be deployed in the future. As we wrote, We conclude
that establishing a just SRM compensation system faces severe difficulties.
This does not necessarily imply that SRM ought never to be deployed, as
there might be satisfactory ways to resolve these difficulties.
Furthermore, even if these difficulties are not fully surmounted, it does
not necessarily follow that SRM deployment would be impermissible. We
certainly don't think the challenges of SRM compensation should create
paralysis among policy makers, nor that the ethical uncertainty involved
provides a decisive reason against deployment, but we do think these
challenges are worth considering. In some future scenario, it might be
permissible to deploy some form of SRM (as I have argued in other published
work--see here
http://muse.jhu.edu/login?auth=0type=summaryurl=/journals/ethics_and_the_environment/v017/17.2.svoboda.html),
but even then we should try to compensate for harm if we can.


Thanks,

Toby Svoboda

2014-08-13 Thread Jamais Cascio
I'm sorry if I was unclear.

Intent and attribution are of course independent of each other, but both would 
be relevant to attempts to secure compensation for post/mid-CE weather 
disasters. Of the two, intent will be the far easier one to determine.

 Again:  Are there fundamental differences in the compensation issue between 
 climate change that is produced intentionally versus climate change that is 
 produced knowingly?


If we go by historical and legal parallels, yes. If your action triggers a 
harmful result that you knew was a possibility and took reasonable measures to 
prevent, the punishment is usually less than if you ignored/discounted that 
possibility, and far less than if you intended that harmful result. In most 
scenarios the potentially-provable accusation would be of negligence, not 
assault with a climate weapon. 

But again, intent is comparatively simple to determine. Attribution will be the 
much more difficult task, and the one most likely to cause a political crisis. 
Proving legally that Weather Disaster X was caused primarily by climate 
engineering will be extremely difficult; proving it politically, conversely, 
will be (unfortunately) quite simple.

 How does whether the intervention was intentional vs. merely knowing affect 
 the attribution problem?
 
 Attribution of effects to causes in physical systems is independent of 
 motivations.  
 
 In either case, damaging third parties was not the goal. In both cases 
 (intentionally vs knowingly causing climate change), someone is will to 
 damage (or risk damaging) third parties to achieve some other goal.
 
 In what ways do the compensation to the third party depend on the details of 
 what the other goal might have been?
 
 Again:  Are there fundamental differences in the compensation issue between 
 climate change that is produced intentionally versus climate change that is 
 produced knowingly?
 
 If I emit CO2 with the intent of changing climate versus the intent of 
 driving to work, does that change anything relevant to compensation or 
 attribution issues?

How does whether the intervention was intentional vs. merely knowing affect
the attribution problem?

Attribution of effects to causes in physical systems is independent of
motivations.

In either case, damaging third parties was not the goal. In both cases
(intentionally vs knowingly causing climate change), someone is will to
damage (or risk damaging) third parties to achieve some other goal.

In what ways do the compensation to the third party depend on the details
of what the other goal might have been?

Again:  Are there fundamental differences in the compensation issue between
climate change that is produced intentionally versus climate change that is
produced knowingly?

If I emit CO2 with the intent of changing climate versus the intent of
driving to work, does that change anything relevant to compensation or
attribution issues?

I use that every time I give a talk on SRM!

Though I'm not quite sure it's entirely apt.

If we burn fossil fuels, we know we are causing damage to large groups of 
people that one could in principle list.  If we choose to implement some 
limited amount of SRM, we can hypothesize that there could be people who would 
be damaged, but as of today, we don't know who or where those might be, other 
than those who benefit from climate change.  (Obviously if we do too much solar 
geoengineering, there would be people who suffer, but with a more realistic 
limited deployment, the suffering is a hypothesis.)

Regarding intentional vs knowing, we do prosecute people who drive drunk and 
kill people, on the basis that we know before doing the drinking that driving 
drunk puts people at risk.  So we certainly do not treat incidental damage as 
irrelevant.

 If I emit CO2 with the intent of changing climate versus the intent of 
 driving to work, does that change anything relevant to compensation or 
 attribution issues?
Forgive the long post, but it's actually a very complex question. Also, I'm 
wearing my U.S. lawyer's hat (but this is a bread-and-butter law school 
question, so maybe that's OK.)
Think of motorboats on a lake. Accept for the sake of argument that a boat's 
engine leaks a certain, well-known amount of oil per mile traveled. One of the 
social purposes of the lake is to allow recreation and enjoyment, including 
boating, and so the release of oil incident to this socially encouraged 
activity will probably be regulated indirectly, by (say) engine maintenence 
requirements, limits on boating permits, a push to improve engine sealing 
technology, payments to facilitate cleanup, etc. (We will hope for the sake of 
the lake that its regulators do a much better job of this than human society 
has done with GHGs.)
Now, if I took a cupful of oil down to the lake and dumped it in (perhaps 
because I think that it will be beneficial for the lake's microbiome), a legal 
regime might well treat that differently--even if I had a license to boat on 
the lake which would, in effect, release that same amount of oil over a similar 
period. True, most regimes would not try to look into your heart of hearts--if 
you hate boating, but you're doing it, gritting your teeth, just to put oil in 
the lake, you won't be regulated differently--but emission without the primary, 
encouraged activity is not automatically the same thing.
So a society might well say that the side effects of permitted, beneficial, 
protected, or necessary activities (and many carbon-emitting behaviors, for 
better or worse, can be included on this continuum) should be regulated 
differently than deliberate release. I think this is why the 
maybe-don't-stop-burning-bunker-fuels-on-the-high-seas argument from a few 
years ago (preserving sulfate release incident to an ordinary economic 
activity) hasn't been nearly as controversial as proposed deliberate release of 
sulfates. Again, not necessarily unreasonable. Incident side effects are 
amenable to collateral regulation (and self-regulation) in ways that deliberate 
activity may not be.
Some digressions:
I think I'm right to claim that, practically speaking, SRM would evolve 
individual releases that were much larger on a per-event or per-actor basis 
than ordinary incident release of sulfates, in addition to being different in 
character (height, location, etc.) This would create further legal distinctions.
For another perspective, take the trolley problem (which I see that Andrew has 
just mentioned). Forgive me for repeating my presentation at the Harvard Summer 
School last year, but a legal system could reasonably punish a bystander who 
diverted a train, killing one person but saving five. Why? Among other reasons, 
the legal system might recognize the problems inherent in allowing or 
encouraging bystanders to make on-the-spot calculations with people's lives, 
even if there are potted hypotheticals where diverting the train seems like the 
better outcome. Rule utilitarianism can reach this outcome as well.
Or take carbon credit markets: If I announce that I'm going to emit CO2 for no 
reason, and then I offer to avoid doing so in exchange for carbon credits, 
should I get them? (Of course, the ability to do this de facto without saying 
you're doing it has been a big problem for carbon credit markets.)
To suggest that none of this should matter is (I think) to take a hard-line 
consequentialist position that you might not want to apply in other contexts.
Also, if you like this kind of discussion, you'll love tort law. The inverse is 
probably also true.
