Project: Marine Cloud Brightening Project (international)

"The Marine Cloud Brightening Project is an open, international collaboration of atmospheric scientists and other experts to advance understanding of cloud responses to aerosol particles - a critical part of understanding the climate, and a critical area in which human activities are thought to cause significant effects."

Crunch Network: Controversial Climate-Change Solution May Be In The Clouds

"In a move that has some environmentalists up in arms, a group of retired Silicon Valley engineers and scientists are proposing a new approach to fighting climate change. They want to brighten clouds. It’s one of the many solutions being proposed in the controversial industry of geoengineering."

Parkes, B.; et al. (2015): Crop failure rates in a geoengineered climate: impact of climate change and marine cloud brightening

Parkes, B.; Challinor, A.; Nicklin, K. (2015): Crop failure rates in a geoengineered climate: impact of climate change and marine cloud brightening. In Environ. Res. Lett. 10 (8), p. 084003–84003. DOI 10.1088/1748-9326/10/8/084003.

"We investigate the impact of a future climate and a potential geoengineering scheme on the number of crop failures in two regions, Northeastern China and West Africa. Climate change associated with a doubling of atmospheric carbon dioxide increases the number of crop failures in Northeastern China while reducing the number of crop failures in West Africa"

Boucher, Olivier (2015): Aerosol-Based Climate Engineering

Boucher, Olivier (2015): Aerosol-Based Climate Engineering. In: Atmospheric Aerosols. Edited by Olivier Boucher. Dordrecht: Springer Netherlands, pp. 287–294. DOI 10.1007/978-94-017-9649-1_13

"This chapter introduces climate engineering as a range of techniques aiming to alleviate the impacts of climate change. Two aerosol-based techniques, known as stratospheric aerosol injection and marine cloud brightening, are discussed in terms of their potential, side effects, and shortcomings."

Korhonen, Hannele; Partanen, Antti-Ilari (2014): Cloud Brightening and Climate Change

Korhonen, Hannele; Partanen, Antti-Ilari (2014): Cloud Brightening and Climate Change. In Bill Freedman (Ed.): Global Environmental Change. Dordrecht: Springer Netherlands, pp. 777–782.

"While climate models suggest that cloud brightening might be able to offset at least some of the predicted global warming, large uncertainties remain related to the efficiency as well as to the environmental and regional climate impacts of the method."

Muri, Helene; et al. (2015): Tropical rainforest response to marine sky brightening climate engineering

Muri, Helene; Niemeier, Ulrike; Kristjánsson, Jón Egill (2015): Tropical rainforest response to marine sky brightening climate engineering. In: Geophys. Res. Lett., S. n/a. DOI: 10.1002/2015GL063363.

"Here, the gross primary productivity (GPP) response of tropical rainforests to climate engineering via marine sky brightening under a future scenario is investigated in three Earth system models. The model response is diverse, and in two of the three models, the tropical GPP shows a decrease from the marine sky brightening climate engineering."
