DownToEarth: What do science-based targets to limit climate change really look like?

"Commitment to climate justice demands that rich countries make deeper cuts to their emissions than merely equalising per-capita emissions by 2030."

Phys.org: Can solar geoengineering mitigate both climate change and income inequality?

"While de-carbonizing the world's emissions sources continues to pose a large challenge, solar geoengineering, which is process where incoming sunlight is intentionally reflected to cool rising temperatures, could help avoid the worst consequences of global warming. This analysis is the first to project the response of Gross Domestic Product (GDP) to the specific pattern of cooling solar geoengineering produces."

MIT Technology Review: Why geoengineering may narrow global economic inequality

"The researchers state that this is a simplified thought exercise to explore these questions. It leaves out of other factors like sea-level rise, glosses over uncertainties about environmental side effects, and assumes high levels of emissions and geoengineering. Moreover, even if things wound up better on average, it still wouldn’t mean that all poor nations would come out ahead."

Harding, Anthony R.; et al. (2020): Climate econometric models indicate solar geoengineering would reduce inter-country income inequality

Harding, Anthony R.; Ricke, Katharine; Heyen, Daniel; MacMartin, Douglas G.; Moreno-Cruz, Juan (2020): Climate econometric models indicate solar geoengineering would reduce inter-country income inequality. In Nat Commun 11 (1), pp. 1–9. DOI: 10.1038/s41467-019-13957-x.

"Combining historical evidence with climate simulations of mean annual temperature and precipitation, we project socio-economic outcomes under high anthropogenic emissions for stylized climate scenarios in which global temperatures are stabilized or over-cooled by blocking solar radiation. We find impacts of climate changes on global GDP-per-capita by the end of the century are temperature-driven, highly dispersed, and model dependent. "

Mirage News: Reflecting sunlight away from earth could fight climate change and poverty

“We find hotter countries respond more to small changes in temperature,” said Moreno-Cruz, who is also Canada Research Chair in energy transitions. “Because poorer countries tend to be hotter, there is a disproportional impact of climate on those countries.

Stephens, Jennie C.; Surprise, Kevin (2020): The hidden injustices of advancing solar geoengineering research

Stephens, Jennie C.; Surprise, Kevin (2020): The hidden injustices of advancing solar geoengineering research. In Global Sustainability 3. DOI: 10.1017/sus.2019.28.

"Solar geoengineering research advances an extreme, expert–elite technocratic intervention into the global climate system that would serve to further concentrate contemporary forms of political and economic power. For these reasons, we argue that it is unethical and unjust to advance solar geoengineering research."

Stephens, Jennie C.; Surprise, Kevin (2020): The hidden injustices of advancing solar geoengineering research. In Glob. Sustain. 3, p. 102. DOI: 10.1017/sus.2019.28.

"We find impacts of climate changes on global GDP-per-capita by the end of the century are temperature-driven, highly dispersed, and model dependent. Across all model specifications, however, income inequality between countries is lower with solar geoengineering. "

Gardiner, Stephen M.; Fragnière, Augustin (2019): Geoengineering, Political Legitimacy and Justice

Gardiner, Stephen M.; Fragnière, Augustin (2019): Geoengineering, Political Legitimacy and Justice. In Ethics, Policy & Environment 21 (3), pp. 265–269. DOI: 10.1080/21550085.2018.1562524.

"The aim of this special issue is to move forward the normative discussion of political legitimacy and justice specifically. Our starting assumption is that it would be unwise to proceed with particular technologies and develop governance systems without at the same time addressing hard questions about justice and legitimacy. One reason for this is that clarifying the central normative questions is key to understanding obstacles to, parameters for, and constraints on research, policy and governance. In particular, it matters for policy if some kinds of geoengineering turn out to be easier from the point of view of justice and legitimacy than others."

Heyward, C. (2018): Normative issues of geoengineering technologies

Heyward, C. (2018): Normative issues of geoengineering technologies. In: TREVOR M. LETCHER (Hg.): MANAGING GLOBAL WARMING. An interface of technology and human issues. [S.l.]: ELSEVIER ACADEMIC PRESS, S. 639–657.

"This chapter gives a brief overview of the emergence of the idea of negative emissions technologies and solar radiation management technologies in climate change policy and the normative issues—questions of values—that they might raise. Normative issues fall into four broad categories: (1) distributive justice, (2) procedural justice, (3) ethical issues, and (4) rectificatory justice."
