Lockley, A.; Futerman, G.; Coffman, D. (2020): Geoengineering and Public Trust Doctrine

Lockley, A.; Futerman, G.; Coffman, D. (2020): Geoengineering and Public Trust Doctrine. In Carbon & Climate Law Review 14 (2), pp. 85–97. DOI: 10.21552/cclr/2020/2/4.

"We consider various types of geoengineering to protect example assets currently under PTD, finding a compelling case for action in a variety of contexts. This introduces a paradoxical situation, where it may theoretically be easier to compel states to undertake geoengineering to protect a beach, than to protect the whole planet."

The Guardian: Negative-emissions tech helps, but it's no magic bullet for the climate crisis

"Sprinkling rock dust on fields can suck up some carbon − but reducing emissions must be the mainstay of our efforts."

NHPR: Outside/In: Is Geoengineering Crazy Enough To Work, Or Just Plain Crazy?

"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?"

Blog post: Hack the Planet: Pulling the climate switch (Anant Kapoor)

"Much like the trolley problem, geoengineering would have a massive accountability dilemma. Any positive action that still leads to calamities will come under heavy scrutiny, so each new disaster would easily be blamed on any prior meddling."

Eurek!Alert: Geoengineering's benefits limited for apple crops in India

"Geoengineering - spraying sulfur dioxide into the atmosphere to combat global warming - would only temporarily and partially benefit apple production in northern India, according to a Rutgers co-authored study."

Bowman, Daniel C.; et al. (2020): Multihour Stratospheric Flights with the Heliotrope Solar Hot-Air Balloon

Bowman, Daniel C.; Norman, Paul E.; Pauken, Michael T.; Albert, Sarah A.; Dexheimer, Darielle; Yang, Xiao et al. (2020): Multihour Stratospheric Flights with the Heliotrope Solar Hot-Air Balloon. In Journal of Atmospheric and Oceanic Technology 37 (6), pp. 1051–1066. DOI: 10.1175/JTECH-D-19-0175.1.

"We have developed a solar-powered hot-air balloon named the heliotrope that can maintain a nearly constant altitude in the upper troposphere–lower stratosphere as long as the sun is above the horizon."

Tilmes, Simone; et al. (2020): Reaching 1.5 and 2.0 °C global surface temperature targets using stratospheric aerosol geoengineering

Tilmes, Simone; MacMartin, Douglas G.; Lenaerts, Jan T. M.; van Kampenhout, Leo; Muntjewerf, Laura; Xia, Lili et al. (2020): Reaching 1.5 and 2.0 °C global surface temperature targets using stratospheric aerosol geoengineering. In Earth Syst. Dynam. 11 (3), pp. 579–601. DOI: 10.5194/esd-11-579-2020.

"A new set of stratospheric aerosol geoengineering (SAG) model experiments has been performed with Community Earth System Model version 2 (CESM2) with the Whole Atmosphere Community Climate Model (WACCM6) that are based on the Coupled Model Intercomparison Project phase 6 (CMIP6) overshoot scenario (SSP5-34-OS) as a baseline scenario to limit global warming to 1.5 or 2.0 C above 1850–1900 conditions. The overshoot scenario allows us to applying a peak-shaving scenario that reduces the needed duration and amount of SAG application compared to a high forcing scenario."
