Your recent post about the summer school mentioned that "...it was still 
difficult to escape being struck by the perception that at this juncture 
North/Western elites are proceeding ahead with very little input from the 
global South".

Two comments.

First and most important: it's true. It's a serious problem. A debate about 
managing the planet's climate must be more inclusive if it's to have any 
legitimacy.

Second, it's also true that the organizing committee of this school worked very 
hard to expand the dialog. A few examples:

*        27% of students were from outside Europe and north America, and about 
a quarter of the total of the total budget was spend on supporting travel for 
students from developing countries (travel for students from Europe and North 
America was generally not supported).

*        By many measures this was the most diverse of the four geoengineering 
summer school's held so far; and, it may have been the most diverse large 
meeting on geoengineering ever held anywhere.

*        Beyond disciplinary and geographical diversity the school also aimed 
to shift the dialog away from the norm in which the old and powerful dispense 
"wisdom" to the young. The first day's lectures which was the only complete and 
comprehensive set of lectures during the school was entirely presented and 
largely managed by early career researchers-no tenured faculty.

None of these facts contradict your basic point which is correct and relevant. 
They do however shed a different light on the actions and intentions of the 
organizers.

Thanks for raising the topic.

Subject: [geo] reflections on summer school at Harvard

There have been quite a few messages posted this week from attendees at the 
Fourth Interdisciplinary Summer School on Geoengineering held at Harvard last 
week August 5-9, but I haven't seen an overview, so I thought I would take a 
stab at it.

Atmospheric overview: There were about 65 people present; about 2/3 were 
graduate students and postdocs in their 20s and 30s with a variety of outliers 
(like me) of different (i.e. older) ages and roles.  The gender split appeared 
to be about 70/30 and about 75% of attendees were from the Northern and Western 
(i.e., Kardashian) hemispheres.   Despite the best intentions of all concerned, 
it was still difficult to escape being struck by the perception that at this 
juncture North/Western elites are proceeding ahead with very little input from 
the global South.  Meetings were held in Pierce Hall (old red brick, comfy 
leather chairs) and Maxwell Dworkin (newer, named after the mothers of donors 
Bill Gates and Steve Ballmer). The agenda was jam-packed: 10-15 speakers the 
first day with 300+ powerpoints, 170 the next day, an all-star debate Wed. 
night--and it was, frankly, quite tiring!  The dorm accommodations at Tufts 
were slightly inferior to a minimum-security Federal prison (no TVs in the 
rooms, linoleum floors) so it was a relief to set off every day on the morning 
hike to campus which passed through Davis and Porter Squares. Overall, the 
student organizers did a great job.

Substance: Here are a few of the points that seemed most interesting *to me* -- 
others surely have different perspectives.

  *   There is still considerable controversy about whether SRM sulfate 
injection can deliver sufficient negative radiative forcing to offset 
anthropogenic component to warming.  From reading enthusiastic articles I had 
formed the impression that this was settled. In fact, there is considerable 
debate over whether there is a saturation point that limits the RF from 
stratospheric sulfate injections.
  *   A relatively lightweight SRM plan described by David Keith could cut the 
rate of climate change in half. I think of this as the "mini-Me" plan since the 
resources required are within the reach of the average mini-mogul, i.e. 2 
Gulfstreams a year ultimately ramping up to 40. Because the sulfate injections 
in this plan are much less than required to set off 2xCO2 doubling, the costs 
and potential side effects are also much less. Crucially the lower level of 
injections reduces the risk from "termination shock" of discontinued SRM 
causing rapid warming. Keith was arguing that the mini-me plan should be 
included in assessments of geoengineering impact and feasibility and he 
convinced me.
  *   A presentation by Eva Ahbe et al. showed what the sky would look like 
after an injection of sulfates sufficient to offset 2xCO2: a halo around the 
sun and no more blue sky -- anywhere on earth. (!!!!)
  *   Everyone still wants to talk about governance. David Keith made a 
persuasive argument that NSF and other funding agencies can and should get 
involved in laying out guidelines in the very near future.  In all likelihood 
these guidelines would set de facto standards going forward which can stand in 
while the global community struggles to agree upon a 192-country framework.
  *   There was relatively little discussion of climate science. Most of the 
discussion was within the framework of "we may find that we have to deliver an 
emergency negative radiative forcing, here are some of the issues." I found 
this rather jarring as I am more accustomed to reading and writing about the 
climate system as an integrated system-of-systems, terrestrial, atmospheric, 
oceanic, land use, water use, energy metabolism, etc., etc. SRM would be a new 
subsystem that would plug in to the existing system of systems and have 
interactions and feedbacks with all of them.  In terms of geo*engineering* this 
systems perspective is also important: systems integration is often a major 
source of technical and project risk.
  *   There was relatively little discussion of natural variability in climate 
and climate history.  I thought this was a problem as it seems to me that there 
will be a lot of challenges in untangling SRM contributions from an already 
extremely tangled web of physical signals that we are already struggling to 
understand (the error bars in many RFs are still quite high).  I would think 
that with the commencement of SRM everyone who is measuring forcings would have 
to revisit their methods to account for the new influence. That is a huge 
ripple effect on all of climate science and would add uncertainty throughout 
the system precisely when the major research focus of the IPCC is to reduce it.
  *   Oliver Morton of the Economist gave a reading from his work in progress 
on geoengineering entitled "The Deliberate Planet". Morton is a very talented 
writer - he reminds me (in an inverse way) of those studies of Alzheimer's 
patients where they show that thought density of journals at age 20 is a good 
predictor of susceptibility to Alzheimer's in later age.  Morton's writing 
style has a very high thought density or level of useful brain convolutions! In 
this title he puts his fingers on something I find  fascinating about 
geoengineering, which is the question whether this would be a brutal and 
hopefully one-time emergency intervention, or whether it is instead a natural 
evolution in the progress of the species towards conscious ongoing management 
of Earth's habitability (e.g. the work by Rockstrom, Hansen et al. to identify 
safe planetary boundaries for climate change).
Enough for the moment; too short on time to expound further and probably at the 
useful limit for email anyway. Please no one be offended by my paraphrase of 
your thoughts or words!

Cordially,

Fred Z.
