Horton, Joshua (2014): Solar Geoengineering: Reassessing Costs, Benefits, and Compensation

Horton, Joshua (2014): Solar Geoengineering: Reassessing Costs, Benefits, and Compensation. In Ethics, Policy & Environment 17 (2), pp. 175–177. DOI 10.1080/21550085.2014.926078.

"In this brief commentary, I will consider the true severity of several of the obstacles identified by Svoboda and Irvine, and make the case that a comprehensive ethical perspective on SRM requires a more complete exploration of the potential costs and benefits of solar geoengineering."

Berdahl, Mira (2014): Impacts of Volcanic Eruptions and Geoengineering on Arctic Climate

Berdahl, Mira (2014): Impacts of Volcanic Eruptions and Geoengineering on Arctic Climate. (A Dissertation submitted to the Graduate School-New Brunswick Rutgers). New Brunswick.

"Here I study the Arctic response to natural (volcanic eruptions) and potential anthropogenic (geoengineering) stratospheric sulfate aerosols. I use a regional climate model and global climate model output from two modeling intercomparison projects."
