Morton, Evvan V. (2020): Reframing the Climate Change Problem: Evaluating the Political, Technological, and Ethical Management of Carbon Dioxide Emissions in the United States. Doctoral Dissertation. Arizona State University. Available online at https://repository.asu.edu/items/57290.

"Although research also confirms that negative emission technologies (NETs) are necessary to stay within 1.5-2°C of global warming, this dissertation proposes that the climate change problem has been ineffectively communicated to suggest that CO2 emissions reduction is the only solution to climate change."

"Keith is working with Frank Keutsch, a professor of atmospheric chemistry, to determine what the effect of that rock dust might be."

"Ever since the threat of climate change was first made public, scientists have offered the possibility of a get-out-of-jail-free card: geoengineering. Reducing emissions is hard, so why not just engineer the Earth's atmosphere more to our liking?  Decades later, the science of geoengineering is still in its infancy, but a growing number of researchers are trying to change that. Should they?"

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."
