YaleEnvironment360: Geoengineer the Planet? More Scientists Now Say It Must Be an Option

"Human intervention with the climate system has long been viewed as an ill-advised and risky step to slow global warming. But with carbon emissions soaring, initiatives to study and develop geoengineering technologies are gaining traction as a potential last resort."

Bluemling, B.; et al. (2019): Seeding the clouds to reach the sky. Will China's weather modification practices support the legitimization of climate engineering?

Bluemling, B.; Kim, R.; Biermann, F. (2019): Seeding the clouds to reach the sky. Will China's weather modification practices support the legitimization of climate engineering? In AMBIO. DOI: 10.1007/s13280-019-01180-3.

"In this Perspective, we discuss whether in times of quickly proceeding global environmental change, radical global interventions like “climate engineering” may gain legitimacy in China and eventually be deployed or supported. We argue that one cornerstone for whether climate engineering, and solar radiation management in particular, could gain legitimacy in China, is its current weather modification programme."

Duan, L.; et al. (2018): Comparison of the Fast and Slow Climate Response to Three Radiation Management Geoengineering Schemes

Duan, L.; Cao, L.; Bala, G.; Caldeira, K. (2018): Comparison of the Fast and Slow Climate Response to Three Radiation Management Geoengineering Schemes. In: J. Geophys. Res. Atmos. DOI: 10.1029/2018JD029034.

"Geoengineering has been proposed as a backup approach to rapidly cool the Earth and avoid damages associated with anthropogenic climate change. In this study, we use the NCAR Community Earth System Model (CESM) to conduct a series of slab‐ocean and prescribed sea‐surface‐temperature simulations to investigate the climate response to three proposed radiation management geoengineering schemes: stratospheric aerosol increase (SAI), marine cloud brightening (MCB), and cirrus cloud thinning (CCT)."

TechCrunch: At what point do we admit that geoengineering is an option?

"We already know how to cool the planet without reducing carbon. The solution is so simple it’s almost laughable: just make our clouds a little more reflective, so they reflect more of the sun’s light, and thus reduce our heat."

The Sydney Morning Herald: 'Truly scary': researcher wants to brighten clouds to rescue the Great Barrier Reef

"Dr Harrison is developing a technology known as “cloud brightening” – encouraging clouds over the reef to deflect more of the sun’s rays back into space, which would hopefully curb rising sea temperatures that cause coral bleaching."

Keller, David P. (2018): Marine Climate Engineering

Keller, David P. (2018): Marine Climate Engineering. In Markus Salomon, Till Markus (Eds.): Handbook on Marine Environment Protection. Science, Impacts and Sustainable Management. 1st edition 2018. Cham: Springer International Publishing, pp. 261–276.

"In this chapter an overview is given of the proposed climate engineering methods that involve the direct manipulation of marine systems. This includes methods that enhance the ocean’s natural physical, chemical, and biological CO2 sequestration pathways, as well as purely technical ones that either use the ocean as a carbon storage reservoir or alter it’s properties to affect the Earth’s radiation budget."

TEDx: We can control climate, but should we? The ethics of geoengineering

"More specifically, the talk focuses on Marine Cloud Brightening, an idea that explores the possibility of "brightening" clouds over the ocean to make them reflect more sunlight away from the Earth. David then encourages the audience to consider the implications of such a drastic and far-reaching solution to global warming, and whether we, as humans, have the right to intentionally perturb our Earth's natural climate systems."

McClatchy: We can brighten clouds to reflect heat and reduce global warming. But should we?

"“We think SRN could buy time for other (carbon-reduction) measures to be put in place,” said Philip J. Rasch, chief climate scientist for the Pacific Northwest National Laboratory in Richland, Washington."
