The Energy Collective: Thermodynamic Geoengineereing: The Fourth Way

"Thermodynamic geoengineering is a fourth way, recently submitted to the MIT climatecolab competition. Thermal stratification of the oceans induced by global warming presents the opportunity to convert warming heat to productive energy."

Horton, Joshua B.; et al. (2015): Liability for Solar Geoengineering. Historical Precedents, Contemporary Innovations, and Governance Possibilities

Horton, Joshua B.; Parker, Andrew; Keith, David W. (2015): Liability for Solar Geoengineering. Historical Precedents, Contemporary Innovations, and Governance Possibilities. In NYU Environmental Law Journal (22), pp. 225–273.

"The absence of liability regimes is sometimes assumed to be a showstopper for solar geoengineering. We examine a set of international liability regimes mostly associated with environmental risks, and suggest that there is a broad legal and historical precedent that might serve as a basis to develop a regime for solar geoengineering."

The Independent: Artificially manipulating Arctic climate by 'whitening' surface of ocean to reflect sunlight back into space will fail, say scientists

Response to Cvijanovic, Ivana; et al. (2015). "Some have suggested that this radical approach should be considered in a global emergency if the summer sea ice of the Arctic disappears completely"

Decode Science: Geoengineering to Combat Climate Change: Carbon Dioxide Removal

"In February, the National Academy of Science released two reports on environmental engineering to counteract climate change. The first report covered Carbon Dioxide Removal (CDR), and the second covered albedo modification. Which of these techniques is the most effective means of helping the environment?"

Science Daily: Whitening the Arctic Ocean: May restore sea ice, but not climate

Response to Cvijanovic, Ivana; et al. (2015). "It has been proposed that such disastrous climate effects could be offset by technological approaches. One such proposal is to artificially whiten the surface of the Arctic Ocean in order to increase the reflection of the Sun's energy into space and restore sea ice."

Cvijanovic, Ivana; et al. (2015): Impacts of ocean albedo alteration on Arctic sea ice restoration and Northern Hemisphere climate

Cvijanovic, Ivana; Caldeira, Ken; MacMartin, Douglas G. (2015): Impacts of ocean albedo alteration on Arctic sea ice restoration and Northern Hemisphere climate. In Environ. Res. Lett. 10 (4). DOI 10.1088/1748-9326/10/4/044020.

"Motivated by this, we investigate the impacts of idealized high latitude ocean albedo changes on Arctic sea ice restoration and climate. In our simulated 4xCO2 climate, imposing surface albedo alterations over the Arctic Ocean leads to partial sea ice recovery and a modest reduction in Arctic warming."

Envisionation: To engineer the climate or not to engineer the climate?

Including interviews with David Keith and Clive Hamilton. "If the answer is “no”, then “good night and good luck.” If the answer is “yes”, then “see you tomorrow (and good luck).”"
