Winickoff, David E.; et al. (2015): Engaging the Global South on climate engineering research

Winickoff, David E.; Flegal, Jane A.; Asrat, Asfawossen (2015): Engaging the Global South on climate engineering research. In Nature Climate change 5 (7), pp. 627–634. DOI 10.1038/nclimate2632.

"The Global South is relatively under-represented in public deliberations about solar radiation management (SRM), a controversial climate engineering concept. This Perspective analyses the outputs of a deliberative exercise about SRM, which took place at the University of California-Berkeley and involved 45 mid-career environmental leaders, 39 of whom were from the Global South."

International Business Times: Controversial Plans to Slow Global Warming by Manipulating Atmosphere Reconsidered by Scientists

"Scientists are revisiting controversial propositions to manipulate the atmosphere and slow down the increase in temperatures on Earth by reflecting more of the sun's energy back into space. Researchers from Harvard School of Engineering and Applied Sciences (SEAS) are proposing a stratospheric perturbation experiment using small amounts of sulphuric acid to block sunlight."

Ferraro, Angus J.; et al. (2014): Weakened tropical circulation and reduced precipitation in response to geoengineering

Ferraro, Angus J.; Highwood, Eleanor J.; Charlton-Perez, Andrew J. (2014): Weakened tropical circulation and reduced precipitation in response to geoengineering. In Environ. Res. Lett. 9 (1), p. 14001–14001. DOI 10.1088/1748-9326/9/1/014001.

"Here, climate model simulations are used to examine the effect of geoengineering on the tropical overturning circulation. The strength of the circulation is related to the atmospheric static stability and has implications for tropical rainfall."
