“…Contrary to what has been proposed in the literature before Victor (2008) Keith et al (2010), the Remediation rule yields higher temperature, lower welfare, and a faster approach to the threshold relative to the other two rules.…”

“…2 The use of SGE as part of the portfolio of options has been suggested in the literature under diverse scenarios. The use of SGE as an insurance against catastrophic climate change has been proposed early in the literature (Keith (2000), Victor (2008), Keith et al (2010), Moreno-Cruz and Keith (2013)). The idea of SGE as a complement to mitigation is proposed in the literature as a way to achieve any given 1 In the appendix we present an alternative model, which more closely follows Naevdal (2003), Naevdal (2006), and Naevdal and Oppenheimer (2007).…”

We study optimal climate policy when climate tipping points and solar geoengineering are present. Solar geoengineering reduces temperatures without reducing greenhouse gas emissions. Climate tipping points are irreversible and uncertain events that cause large damages. We analyze three different rules related to the availability of solar geoengineering: a ban, using solar geoengineering as insurance against the risk of tipping points, or using solar geoengineering only as remediation in the aftermath of a tipping point. We model three distinct types of tipping points: two that alter the climate system and one that yields a direct economic cost. Using an analytic model, we find that an optimal policy, which minimizes expected losses from the tipping point, includes both emissions reductions and solar geoengineering from the onset.Using a numerical simulation model, we quantify optimal policy and various outcomes under the alternative scenarios. The presence of tipping points leads to more mitigation and more solar geoengineering use and lower temperatures. * We thank Derek Lemoine and seminar participants at Tennessee, Stanford, Harvard, and the Southern Economic Association annual meeting for comments.

“…Some have even gone so far as to claim that, since SRM is an imperfect substitute for emissions abatement, a positive SRM R&D decision will not affect GHG emissions abatement (Bunzl 2009). This conjecture, which we dub "abatement invariance", contrasts with a third conjecture, namely that investment in SRM R&D detracts from mitigation and will lead to less abatement effort (Keith 2010, Shepherd 2009). This possibility of a reduction in mitigation effort by the current generation has been characterized as a manifestation of "moral hazard" that a rational course of action would avoid (Shepherd 2009, Hale 2012.…”

“…3 Already in one of the early reports by the US National Academy of Sciences on climate change, the authors once those technological capabilities have been created, is the argument underpinning two additional conjectures advanced in the literature. One is that the rational course of action for today's generation is to rule out research on geoengineering measures in order to prevent the future generation from acting against its own best interests (Keith et al 2010). 4 The fifth conjecture is a different interpretation of the "moral hazard" argument by Bunzl (2009) and turns the logic on its head.…”

Abstract Solar radiation management (SRM) technologies are considered one of the likeliest forms of geoengineering. If developed, a future generation could deploy them to limit the damages caused by the atmospheric carbon stock inherited from the current generation, despite their negative side effects. Should the current generation develop these geoengineering capabilities for a future generation? And how would a decision to develop SRM impact on the current generation's abatement efforts? Natural scientists, ethicists, and other scholars argue that future generations could be more sanguine about the side effects of SRM deployment than the current generation. In this paper, we add economic rigor to this important debate on the intergenerational transfer of technological capabilities and pollution stocks. We identify three conjectures that constitute potentially rational courses of action for current society, including a ban on the development of SRM. However, the same premises that underpin these conjectures also allow for a novel possibility: If the development of SRM capabilities is sufficiently cheap, the current generation may for reasons of intergenerational strategy decide not just to develop SRM technologies, but also to abate more than in the absence of SRM.

“…This was a discourse that was popular with the engineers and technicians who made up Focus Group 5, and who appeared to be more accepting, philosophically, of the idea of using technology to deliberatively intervene in the Earth's climate system. The idea of solar radiation management 'buying time' is a discourse common amongst geoengineering researchers in arguments promoting the need for research (see Caldeira and Keith, 2010;Keith et al, 2010). …”
