"A key question for climate policy in general, but even more in the case a rapid response is needed, is: what are the characteristic response times of the response options, such as rapid mitigation or solar radiation management (SRM)?"

Expert discussion. "Two leading climate academics – Ken Caldeira and Clive Hamilton – debate the issue of geoengineering and whether it should be allowed to go-ahead"

"The most difficult issues lie in the areas of ethics, politics, and governance.  As communities and policymakers around the world face the risks presented by a rapidly changing climate, understanding the scientific, ethical, and governance issues at the core of geoengineering research will be critical to making informed decisions about response options."

Aerosol modeling study that is connected to SRM. "We suggest that sporadic volcanic eruptions in the Northern Hemisphere also strongly influence this gradient and cause Sahelian drought. Using de-trended observations from 1900 to 2010, we show that three of the four driest Sahelian summers were preceded by substantial Northern Hemisphere volcanic eruptions."
