Lenferna, Alex; et al. (2017): Relevant Climate Response Tests for Stratospheric Aerosol Injection. A Combined Ethical and Scientific Analysis

Lenferna, Alex; Russotto, Rick; Tan, Amanda; Gardiner, Stephen; Ackerman, Thomas (2017): Relevant Climate Response Tests for Stratospheric Aerosol Injection. A Combined Ethical and Scientific Analysis. In Earth's Future. DOI: 10.1002/2016EF000504.

"In this paper, we focus on stratospheric sulfate injection as a geoengineering scheme, and provide a combined scientific and ethical analysis of climate response tests, which are a subset of outdoor tests that would seek to impose detectable and attributable changes to climate variables on global or regional scales. We assess the current state of scientific understanding on the plausibility and scalability of climate response tests. Then we delineate a minimal baseline against which to consider whether certain climate response tests would be relevant for a deployment scenario. Our analysis shows that some climate response tests, such as those attempting to detect changes in regional climate impacts, may not be deployable in time periods relevant to realistic geoengineering scenarios. This might pose significant challenges for justifying SSI deployment overall."

Lawford-Smith, H.; Currie, A. (2017): Accelerating the carbon cycle: the ethics of enhanced weathering

Lawford-Smith, H.; Currie, A. (2017): Accelerating the carbon cycle: the ethics of enhanced weathering. In Biology letters 13 (4). DOI: 10.1098/rsbl.2016.0859

"We argue that ethical concerns have a place alongside empirical, political and social factors as we consider how to best respond to the critical challenge that anthropogenic climate change poses. We review these concerns, considering the ethical issues that arise (or would arise) in the large-scale deployment of enhanced weathering. We discuss post-implementation scenarios, failures of collective action, the distribution of risk and externalities and redress for damage."

Carnegie Council: The Ethics and Governance of Geoengineering

"Now of course, the most important serious action is to redouble our efforts to reduce emissions. Absolutely that is what we all need to do, and there is a lot of potential. And theoretically, from a geophysical point of view, we can reach those targets—no problem. The question is: Can we also do that from a political standpoint and social acceptance point of view?"

Baatz, Christian; Ott, Konrad (2016): Why Aggressive Mitigation Must Be Part of Any Pathway to Climate Justice

Baatz, Christian; Ott, Konrad (2016): Why Aggressive Mitigation Must Be Part of Any Pathway to Climate Justice. In Christopher J. Preston (Ed.): Climate Justice and Geoengineering: Rowman & Littlefield International.

Chapter in Preston, Christopher J. (Ed.) (2016) by two SPP researchers. "This contribution's aim is twofold: on the one hand, we argue that wealthy high-emitting countries are obligated to radically lower their greenhouse gas (GHG) emissions, and if undertaken properly, this will very likely not overburden their respective citizen (section 2); on the other hand, we defend the primacy of mitigation duties arguing that possible obligations to adopt further supplementary strategies do not diminish these (section 3)."

Lambini, Cosmas Kombat (2016): Internalising Solar Radiation Management Technological Externalities. An ethical review on the design of economic instruments

Lambini, Cosmas Kombat (2016): Internalising Solar Radiation Management Technological Externalities. An ethical review on the design of economic instruments. In Advances in Climate Change Research. DOI 10.1016/j.accre.2016.04.003.

"Technical and ethical challenges need to be assessed and addressed before any possible compensation system is designed and implemented. Further research need to be conducted and scenarious analysis on SRM possible effects and effective control policies to be tested and implemented."

Katz, Eric; Hargrove, Eugene C. (2015): Geoengineering, Restoration, and the Construction of Nature

Katz, Eric; Hargrove, Eugene C. (2015): Geoengineering, Restoration, and the Construction of Nature. In Environmental Ethics 37 (4), pp. 485–498. DOI 10.5840/enviroethics201537444.

"My argument is based on my critique of the process of ecological restoration as the creation of an artifactual reality. When humanity intentionally interferes with the processes and entities of nature, we change the ontological reality of the natural world. The world becomes a garden, or a zoo, an environment that must be continually managed to meet the goals of human purposes."

Good Magazine: Peter Singer on the COP21 Agreement and the Ethics of Climate Change

"Peter Singer is arguably one of the world’s best-known modern philosophers. Singer has been based out of Princeton University since 1999 and has a host of awards and honors to his name. [...] Singer: One possibility that’s been discussed is to engage in some form of geo-engineering to artificially cool the planet. Nobody has talked about what kind of international law foundation there would be for doing that. But [in that case] we would get more rapid discussion of geo-engineering and at least research into it to see what would work."
