“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.”
“Last Tuesday, two speakers addressed the problematic of “geo-engineering” from two very different angles.”
Press review of the paper Cvijanovic, Ivana; et al. (2015): Impacts of ocean albedo alteration on Arctic sea ice restoration and Northern Hemisphere climate
“On May 4 through May 6, the Project on International Order and Strategy at Brookings and the Global Public Policy Institute (GPPi) of Berlin will formally release three “Global Governance Futures 2025” research papers.”

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

“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.”
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).””
