Imperial College London: Countries must work together on CO2 removal to avoid dangerous climate change

"The Paris Agreement lays out national quotas on CO2 emissions but not removal, and that must be urgently addressed, say the authors of a new study."

Pozo, Carlos; et al. (2020): Equity in allocating carbon dioxide removal quotas

Pozo, Carlos; Galán-Martín, Ángel; Reiner, David M.; Mac Dowell, Niall; Guillén-Gosálbez, Gonzalo (2020): Equity in allocating carbon dioxide removal quotas. In Nat. Clim. Chang. DOI: 10.1038/s41558-020-0802-4.

"Drawing on existing equity frameworks, we allocate CDR quotas globally according to Responsibility, Capability and Equality principles. These quotas are then assessed in the European Union context by accounting for domestic national capacity of a portfolio of CDR options, including bioenergy with carbon capture and storage, reforestation and direct air capture. We find that quotas vary greatly across principles, from 33 to 325 GtCO2 allocated to the European Union, and, due to biophysical limits, only a handful of countries could meet their quotas acting individually. These results support strengthening cross-border cooperation while highlighting the need to urgently deploy CDR options to mitigate the risk of failing to meet the climate targets equitably."

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. "
