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.“

Project: Climateworks. About the Pilot and Demonstration Project

Swiss direct air capture project. „The overall goal is to design, build and continuously operate an industrial scale CO2[nbsp]capture plant and sell atmospheric CO2[nbsp]to a customer.[nbsp]The plant will be operational by mid-2016 and annually capture 900 tons of CO2[nbsp]from the atmosphere, enhancing the growth of vegetables and lettuce in a nearby greenhouse of Gebrüder Meier by up to 20 percent.[nbsp]The plant is constructed as part of a three-year pilot and demonstration project with Gebrüder Meier and Zweckverband Kehrichtverwertung Zürcher Oberland KEZO (a municipal waste disposal company) as project partners. The project is supported by the Swiss Federal Office of Energy (SFOE).“

Heyen, Daniel; et al. (2015): Regional disparities in SRM impacts. The challenge of diverging preferences

Heyen, Daniel; Wiertz, Thilo; Irvine, Peter James (2015): Regional disparities in SRM impacts. The challenge of diverging preferences. In Climatic Change. DOI: 10.1007/s10584-015-1526-8[nbsp]

„We challenge this strong change-is-bad assumption by showing that diverging preferences are not only plausible, but may also have the potential to substantially alter assessments of regional disparities. We argue that current assessments yield little information on the ethical and political implications of SRM and that diverging preferences should receive more attention. Promising directions for future inquiry include bridging gaps to the general climate impact research and to research on the social implications of environmental change.“

The Center for Carbon Removal: Recap: Oxford Conference on Carbon Removal

„Here’s are the three most important things I took away from the event: 1. Research and development of carbon removal solutions is progressing in a number of the carbon removal fields. 2. But there are still numerous uncertainties surrounding all of the carbon removal solutions, particularly around[nbsp]the sustainable scale potential. 3. The policy and governance conversation around carbon removal is fairly advanced“

Bürger, Gerd; Cubasch, Ulrich (2015): The detectability of climate engineering

Bürger, Gerd; Cubasch, Ulrich (2015): The detectability of climate engineering. In J. Geophys. Res. Atmos., pp.[nbsp]n/a-n/a. DOI: 10.1002/2015JD023954[nbsp]

„We assess the detection and attribution (D[&]A) of climate engineering (CE) as a function of their duration after initiation. We employ “surrogate” climates where observations are mimicked by simulations. Unlike classical, stationary D[&]A, the null hypothesis for this analysis is the non-stationary gradual warming caused by continued greenhouse gas (GHG) forcing, which creates a number of theoretical and technical complications.“

Datta, Shuvo Jit; et al. (2015): CO2 capture from humid flue gases and humid atmosphere using a microporous coppersilicate

Datta, Shuvo Jit; Khumnoon, Chutharat; Lee, Zhen Hao; Moon, Won Kyung; Docao, Son; Nguyen, Thanh Huu et al. (2015): CO2 capture from humid flue gases and humid atmosphere using a microporous coppersilicate. In Science 350 (6258), pp.[nbsp]302–306. DOI: 10.1126/science.aab1680[nbsp]

„We report a highly stable microporous coppersilicate. It has H2O-specific and CO2-specific adsorption sites but does not have H2O/CO2-sharing sites. Therefore, it readily adsorbs both H2O and CO2 from the humid flue gases and atmosphere, but the adsorbing H2O does not interfere with the adsorption of CO2.“
