WGC Blog: Guest Post- Tina Johnson, Energy Action Coalition – A Call for Engagement by Environmental Justice Groups in the Geoengineering Conversation

„It is no longer prudent for the environmental movement to think of geoengineering as a closeted secret of quack scientists or something out of an Isaac Asimov novel. […] There is an urgency that is required of the environmental movement to talk about what failure to win on mitigation or adaptation on a large scale, in meaningful ways, could likely result in[nbsp]–[nbsp]geoengineering/climate engineering of the environment as the only option.“

Seidel, Dian J.; et al. (2014): Detection limits of albedo changes induced by climate engineering

Seidel, Dian J.; Feingold, Graham; Jacobson, Andrew R.; Loeb, Norman (2014): Detection limits of albedo changes induced by climate engineering. In Nature Climate change 4 (2), pp. 93–98. DOI 10.1038/nclimate2076.

„We show that satellite observations permit detection of large increases, but interannual variability overwhelms the maximum conceivable albedo increases for some schemes.“
