"Current climate engineering proposals do not come close to addressing the complex and contested nature of conceivable 'climate emergencies' resulting from unabated greenhouse-gas emissions."

Niemeier, U.; Timmreck, C. (2015): What is the limit of stratospheric sulfur climate engineering? In Atmos. Chem. Phys. Discuss. 15 (7), pp. 10939–10969. DOI 10.5194/acpd-15-10939-2015.

"The injection of sulfur dioxide (SO₂) into the stratosphere to form an artificial stratospheric aerosol layer is considered as an option for solar radiation management. The related reduction in radiative forcing depends upon the amount injected of sulfur dioxide but aerosol model studies indicate a decrease in forcing efficiency with increasing injection magnitude."

"One way to combat climate change could be to release synthetic organisms that sequester carbon. How this can be done safely is a question bioengineers are now beginning to address.One way to combat climate change could be to release synthetic organisms that sequester carbon.
