"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."

"We advance preliminary suggestions to address two priority areas for early investigation: how international cooperation on early CE research can help develop shared norms that can grow robust enough to support future decision needs; and how early research and development on CE can be made to complement and encourage, rather than undermine, parallel efforts to reduce climate risks by cutting emissions."

" We argue that there are two reasons for the rise of interest in geoengineering." 1. failing international climate negotiation, 2. advancement in CE technologies.
