The Nation: Why Geoengineering Is ‘Untested and Untestable’

By Naomi Klein. "An opinion piece in Nature calling for geoengineering tests fails to mention the most significant problem with these experiments."

WGC Blog: Wading into a Murky Debate on Transparency

"Because of this, the question of transparency in CE research has very quickly moved from whether to how – and it is within this much more quiet debate about implementation that support for new transparency policies and standards may become less staunch."

Bulletin of the Atomic Scientists: Not enough time for geoengineering to work?

"Just as slamming on the brakes can slow down a train headed for a ravine, geoengineering can cool the climate. But it won’t happen without a lot of bruising, and it’s not a quick fix."

Bahn, Olivier; et al. (2015): Is there room for geoengineering in the optimal climate policy mix?

Bahn, Olivier; Chesney, Marc; Gheyssens, Jonathan; Knutti, Reto; Pana, Anca Claudia (2015): Is there room for geoengineering in the optimal climate policy mix? In Environmental Science & Policy 48, pp. 67–76. DOI 10.1016/j.envsci.2014.12.014.

"The optimal climate portfolio is a mix of mitigation, adaptation, and SRM. When accounting for uncertainty in the magnitude of SRM side-effects and their persistency over time, we show that the SRM option lacks robustness."

WGC Blog: Guns do kill people: reasons to worry about moral hazard in geoengineering

"In this blog I plan to briefly rebut each of these arguments, and instead make the case that we must properly recognize the social implications of technology, and therefore should already be gravely worried about the moral hazard effects of geoengineering."

Chemistry World: Switching desalination plants from carbon dioxide source to sink

Response to Davies, P. A. (2015). "A UK researcher has proposed a new process to decompose waste desalination brine using solar energy that could allow desalination plants to act as a sink rather than a source of atmospheric carbon dioxide, and help to neutralise ocean acidity."

Davies, P. A. (2015): Solar thermal decomposition of desalination reject brine for carbon dioxide removal and neutralisation of ocean acidity

Davies, P. A. (2015): Solar thermal decomposition of desalination reject brine for carbon dioxide removal and neutralisation of ocean acidity. In Environ. Sci.: Water Res. Technol. DOI 10.1039/c4ew00058g.

Linked to CE. "Desalination plants could become net absorbers (rather than net emitters) of CO2. Thermal decomposition of salts in desalination reject brine can yield MgO which, added to the ocean, would take up CO2 through conversion to bicarbonate."
