Nature News: Climate scientists ponder spraying diamond dust in the sky to cool planet

Response to Weisenstein, D. K.; et al. (2015). "Solid particles of diamond or alumina might be safer than sulphate droplets as a way to redirect the Sun’s energy, calculations suggest."

Weisenstein, D. K.; et al. (2015): Solar geoengineering using solid aerosol in the stratosphere

Weisenstein, D. K.; Keith, D. W.; Dykema, J. A. (2015): Solar geoengineering using solid aerosol in the stratosphere. In Atmos. Chem. Phys. 15 (20), pp. 11835–11859. DOI: 10.5194/acp-15-11835-2015 

"We use a two-dimensional (2-D) chemistry–transport–aerosol model to capture the dynamics of interacting solid and liquid aerosols in the stratosphere. [...] Our results suggest that appropriately sized alumina, diamond or similar high-index particles may have less severe technology-specific risks than sulfate aerosols do. These results, particularly the ozone response, are subject to large uncertainties due to the limited data on the rate constants of reactions on the dry surfaces."

CNN: Will hacking nature protect us from climate change?

"One way to keep global average temperatures from warming beyond a catastrophic 2-degree-celsius tipping point, according to some experts, is to suck massive amounts of CO2 out of the atmosphere."

environment 360: How 'Third Way' Technologies Can Help Turn Tide on Climate

"In a Yale Environment 360 interview, Australian scientist and author Tim Flannery explains how the development of technologies that mimic the earth’s natural carbon-removing processes could provide a critical tool for slowing global warming. "

Moore, John C.; et al. (2015): Atlantic hurricane surge response to geoengineering

Moore, John C.; Grinsted, Aslak; Guo, Xiaoran; Yu, Xiaoyong; Jevrejeva, Svetlana; Rinke, Annette et al. (2015): Atlantic hurricane surge response to geoengineering. In Proc Natl Acad Sci USA, p. 201510530. DOI: 10.1073/pnas.1510530112 

"We estimate that stratospheric sulfate aerosol geoengineering may somewhat ameliorate Atlantic hurricane intensity and frequency, but there will be more “Katrina”-level events than during the past 30 y. Geoengineering would likely be reasonably effective at controlling coastal flood risk relative to the coastal flood risk expected under the Representative Concentration Pathway (RCP) 4.5 greenhouse gas warming, in part, due to its impact on global sea level rise, although flood risk would still be significantly larger than at present."

Asia One: Shivers over growing plankton to cool earth

"Fertilising the seas to create a plankton bloom may sound like a bad idea, as these mounds of microalgae have caused mass fish deaths in Singapore and around the world. But some scientists believe it will help reduce carbon dioxide, a greenhouse gas, and combat global warming."

Box, Michael A.; Box, Gail P. (2016): Physics of radiation and climate

Box, Michael A.; Box, Gail P. (2016): Physics of radiation and climate. Boca Raton, FL: CRC Press, Taylor & Francis Group.

Book including a chapter (18.2) on CE."Physics of Radiation and Climate takes a look at how the outward flow of longwave or terrestrial radiation is affected by the complexities of the atmosphere’s molecular spectroscopy. This book examines the planet in its current state and considers the radiation fluxes, including multiple scattering, photochemistry, and the ozone layer, and their impact on our climate overall."

Chris, Robert (2015): Systems thinking for geoengineering policy

Chris, Robert (2015): Systems thinking for geoengineering policy. Balsingstoke: Routledge.

"Systems Thinking for Geoengineering Policy is the first book to theorise geoengineering in terms of complex adaptive systems theory and to argue for the theoretical imperative of adaptive management as the default methodology for an effective low risk means of confronting the inescapable uncertainty and surprise that characterise potential climate futures. The book illustrates how a shift from the conventional Enlightenment paradigm of linear reductionist thinking, in favour of systems thinking, would promote policies that are robust against the widest range of plausible futures rather than optimal only for the most likely, and also unlock the policy paralysis caused by making long term predictions of policy outcomes a prior condition for policy formulation."

Sutton, Philip (2015): Striking Targets. Matching Climate Goals with Climate Reality

Sutton, Philip (2015): Striking Targets. Matching Climate Goals with Climate Reality. Breakthrough.

Including carbon removal in a policy mix. "In this latest paper, Philip Sutton highlights what he sees as an impending shift in the purpose of climate campaigning and calls for the most effective action in the new ‘post-Paris’ era."
