Well, the brief description in the Lawrentian leaves out much. I certainly
mentioned the adverse impacts SRM is proposed to counteract.  I spent 15
minutes in the beginning discussing the "nightmare rationale" for SRM and I
played the newly released IASS video (http://youtu.be/3GKjl7afwaY) to
introduce the topic (on a sidenote, the video was very well received).
Perhaps there's a discussion to be had about whether the video gives a fair
overview of the rationales for doing SRM. The previous lecture in this
series was dedicated to the science and pros/cons of SRM/geoengineering. My
lecture was on ethical and moral issues that arise in the discourse on SRM,
research and governance, picking up where the other left off. Thus, it was
not my job to do a hard sell of the tipping point argument for SRM.

The main ethical problem with SRM, I think, is political legitimacy. Almost
200 sovereign states with maybe 9 billion souls would be affected and have
different perspectives on what ought to be done and how. If you add "in a
situation of multiple regional drought/flood catastrophes, with a small
window of opportunity, where many people nevertheless will have pragmatic
or ethical doubts about the wisdom of using technology to fix a problem
caused by technology in combination with the human condition; a situation
where there would almost certainly be significant power differentials
between relative global winners and losers", you have social complexity
approaching off the scales compared to the rather ordinary (and still
(nearly) unresolvable) political problems we face today. The kind of global
institution that could arbitrate such a situation and make a timely,
authoritative, legitimate and lawful decision about SRM that would be
universally respected and obeyed does not exist, and it is hard to see that
it ever will. Now, perhaps that is too high a bar to set - perhaps it would
be enough that a majority of the global population were represented by
states that wanted SRM and a multilateral consortium implemented it
regardless of the wishes of everyone else. Various other conditions that
could bestow sufficient legitimacy on anyone wanting to geoengineer without
global consensus is worth a discussion on its own (could the end ever
justify the means? Is the only kind of justification possible a ex-post
justification in a scenario where risks and consequences of SRM turned out
to be overblown?). Regardless, all scenarios that would see SRM implemented
would have to overcome really serious ethical and moral obstacles; these
would either have to be resolved in some fashion. Discussion of ethical
issues therefore has to start now.

The prospect of tipping points terrify me - I'm quite convinced they are
plausible. Whether SRM terrifies me more depends on what side of the bed I
got out on in the morning.
