Jones, Anthony C.; et al. (2017): Impacts of hemispheric solar geoengineering on tropical cyclone frequency

Jones, Anthony C.; Haywood, James M.; Dunstone, Nick; Emanuel, Kerry; Hawcroft, Matthew K.; Hodges, Kevin I.; Jones, Andy (2017): Impacts of hemispheric solar geoengineering on tropical cyclone frequency. In Nat Comms 8 (1), p. 1382. DOI: 10.1038/s41467-017-01606-0.

"Observations following major volcanic eruptions indicate that aerosol enhancements confined to a single hemisphere effectively modulate North Atlantic tropical cyclone (TC) activity in the following years. Here we investigate the effects of both single-hemisphere and global SAI scenarios on North Atlantic TC activity using the HadGEM2-ES general circulation model and various TC identification methods."

Indipendent: Artificial volcanoes designed to reverse global warming could risk natural disasters, scientists warn

"Geoengineering to cool the Earth’s climate by imitating volcanic eruptions is a ‘highly risky strategy’ that may increase the frequency of cyclones and droughts in some parts of the world"

Carr, Wylie; Preston, Christopher J. (2017): Skewed Vulnerabilities and Moral Corruption in Global Perspectives on Climate Engineering

Carr, Wylie; Preston, Christopher J. (2017): Skewed Vulnerabilities and Moral Corruption in Global Perspectives on Climate Engineering. In environ values 26 (6), pp. 757–777. DOI: 10.3197/096327117X15046905490371.

"The research presented in this paper was designed to build knowledge about how vulnerable populations think about climate engineering. The goal of this manuscript is to bring the ethics literature on climate engineering into dialogue with emerging social science data documenting the perspectives of vulnerable populations. The results indicate some concerns among vulnerable populations may resemble those outlined by ethicists."

Heutel, Garth; et al. (2017): Solar Geoengineering, Uncertainty, and the Price of Carbon

Heutel, Garth; Moreno-Cruz, Juan; Shayegh, Soheil (2017): Solar Geoengineering, Uncertainty, and the Price of Carbon. In Journal of Environmental Economics and Management. DOI: 10.1016/j.jeem.2017.11.002.

"We consider the socially optimal use of solar geoengineering to manage climate change and its implications for carbon emissions abatement policy. We show that solar geoengineering is a substitute for emissions abatement; optimal policy includes less abatement, by up to eight percentage points, and has a lower carbon price, by up to fifteen percent, than recommended by models that ignore solar geoengineering. However, it is an imperfect substitute, since it reduces temperature without reducing atmospheric or ocean carbon concentrations."

Harvard Political Review: The Earth in Our Hands: Geoengineering’s World-Changing Prospects

"Perhaps geoengineering is simply inevitable. As Caldeira, echoing one of his colleagues, astutely observed, “When has humanity ever developed the ability to control its environment and then not exercised that control?” The world must quickly engineer a solution to the climate crisis, and geoengineering provides a possible answer."

Third Way: Negative Emissions Primer

" fact, today, we’ve already gone through about 73% of our carbon budget (aka how much carbon can be in the air before warming rises to an unsafe level). We can and should ramp up deployment of clean energy technologies. But, we also have a secret weapon that many experts think we’ll absolutely need to keep warming to a safe level: negative emissions technologies."
