“With prominent scientists now calling for experiments to test whether pumping sulfates into the atmosphere could safely counteract global warming, critics worry that the world community may be moving a step closer to deploying this controversial technology.”
Media response to Ferraro, Angus J.; et al. (2014). “Proposal to inject tiny reflective particles into the upper atmosphere to block out sunlight could lead to droughts, warn scientists.”

“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.”

Comparing China’s climate policy options. “While China could hold back on implementing geoengineering given a remarkable amount of international cooperation on limiting fossil carbon burning, an outcome where geoengineering is used to delay the perceived need to limit the atmospheric CO2 concentration may be difficult to avoid.”
Critical article on CE.
Idea about pollution, but no classical CE technollogy. “Spraying water into the air from sprinklers on tall buildings and towers, like watering a garden, could cut air pollution in Chinese cities, a scientist says.”

“This paper considers the potential for the UNCLOS and UNFCCC regimes to be faced with disputes at the intersection between the management of climate change and ocean governance. Using the example of geo-engineering[.]”
