Horton, J. B. (2015): The emergency framing of solar geoengineering: Time for a different approach. In: The Anthropocene Review. DOI: 10.1177/2053019615579922.

"Solar geoengineering has been proposed as a possible response measure in the event of a ‘climate emergency’. Scientific evidence for climate emergencies in the form of tipping points, however, is contested and unsettled."

"The second best hope is for the world to start putting some serious effort into mitigation: geo-engineering to slow the warming, and figuring out what to do with various low-lying and drought-prone places."
