[geo] Governing Climate Engineering: A Proposal for Immediate Governance of Solar Radiation Management

[Andrew Lockley]

https://www.mdpi.com/2071-1050/11/14/3954

Abstract
Solar radiation management (SRM) technologies would reflect a small amount
of incoming solar radiation back into space before the radiation can warm
the planet. Although SRM may emerge as a useful component of a global
response to climate change, there is also good reason for caution. In June
2017, the Academic Working Group on Climate Engineering Governance released
a policy report, “Governing Solar Radiation Management”, which developed a
set of objectives to govern SRM in the near-term future: (1) keep
mitigation and adaptation first; (2) thoroughly and transparently evaluate
risks, burdens, and benefits; (3) enable responsible knowledge creation;
and (4) ensure robust governance before any consideration of deployment. To
advance the governance objectives identified above, the working group
developed twelve recommendations, grouped into three clusters: (1) create
politically legitimate deliberative bodies; (2) leverage existing
institutions; and (3) make research transparent and accountable. This
communication discusses the rationale behind each cluster and elaborates on
a subset of the recommendations from each cluster.

[geo] Volcanoes and low earth orbit

[Andrew Lockley]

Hi

I'm trying to look at the potential effects of solar radiation management
geoengineering on low Earth orbit. It's been suggested to me that volcanoes
may have a comparable effect, as they are typically used as an analogue.
Does anyone have experience of either observing or modelling the impact of
of volcanoes on low Earth orbit? I'm specifically interested in issues of
orbital Decay

The troposphere cools, the stratosphere warms. It's unclear what the net
effect is

I have no experience.  Some thoughts-- Earth atmosphere mass:  5.15*10^18
kg.   Mass of gas emitted by Mt. Pinatubo in 1991:  2.5*10^11 kg.  On the
other hand, the earth atmosphere is expected to contract by about 1% due to
cooling.  Satellite decay would be less.

Re: [geo] Governing Climate Engineering: A Proposal for Immediate Governance of Solar Radiation Management

[Ronal Larson]

Andrew and list

1.Thanks for your https://www.mdpi.com/2071-1050/11/14/3954 
 cite below - this for a 9 page, 
non-fee, 4-day old paper that is of direct interest to SRM (Geo without CDR).  
I especially like that it was written by experts on governance (but initially 
not on SRM), who were divided on SRM itself, and had many discussions on the 
topic over multiple years.  
I find nothing wrong with any part of the paper.   I hope the same 
group can continue on with governing CDR (the other part of Geoengineering).  
Comparing the governance ideas of SRM with those for CDR should help both 
groups - as well as policymakers.  I would guess that CDR could now take much 
less than half the time as for SRM, even with CDR's much broader array of 
options.
This appears to have been conducted very much like a jury deliberation 
- with proponents NOT involved in the deliberations.  I believe this approach 
will give better results in most cross comparisons.


2.Here is a short outline.  This is probably less than about 1% of 
the article - intended only to encourage a full read and for use by other 
technologies or groups of technologies (especially CDR).

 Abstract: (see below)

1. Introduction ……... The working group met for five deliberative workshops 
between March 2016 and February 2018. The chief findings of the working group’s 
report are detailed below. All recommendations presented in this article are 
derived from the working group report.

 2. Background on the Process 

 3. Governance Objectives
3.1. Objective I—Keep Mitigation and Adaptation First 
3.2. Objective II—Thoroughly and Transparently Evaluate Risks, Burdens, and 
Benefits 
3.3. Objective III—Enable Responsible Knowledge Creation 
3.4. Objective IV—Ensure Robust Governance Before any Consideration of 
Deployment 

4. Recommendations: Concrete Near-Term Governance Steps 

  Cluster #1: Create Politically Legitimate Deliberative Bodies:
1 Establish a World Commission on SRM;
2 Establish a Global Forum for Stakeholder Dialogue 

  Cluster #2: Leverage Existing Institutions 
3 Strengthen cooperation between international organizations;
4 Assess and improve capacities for regional coordination and conflict 
resolution;
5 Continue ongoing assessment role for the Intergovernmental Panel on 
Climate Change…..;   
6 Develop foresight capabilities 

  Cluster #3: Make Research Transparent and Accountable 
7 Report on SRM research and development activities in the Paris 
Agreement….;   
8 Institutionalize codes of conduct for responsible SRM research; 
9 Ensure that ongoing research includes international and interdisciplinary 
collaboration;   
   10 Clarify funding streams
   11 Develop a publicly accessible clearinghouse;
   12 Develop best practices for risk and impact assessments

5. Conclusions The working group argues that SRM governance should begin now. 
Some members see SRM development as desirable; some as potentially dangerous. 
Whatever the perspective, governance will be required to prompt the careful 
deliberation and oversight needed to make decisions about SRM in the societal 
interest. The working group’s recommendations establish essential rules and 
institutional arrangements for near-term understanding and guidance of SRM 
research, they also begin building the scaffolding for effective long-term 
governance. 



3.   In sum,  I find all parts of this reasonable for the SRM part of Geo.  The 
only recommendation I have so far is to hope they can tie CDR into their 
recommendations.

 I will forward this to both the Google CDR and Yahoo Biochar lists  - with 
separate notes pertinent to each.   For example, the “ before” part of their 
Objective 4 seems too late for most of CDR and certainly for biochar..
