Washington Post: Earth’s chill pill?

„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.“
„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; 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.“
„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.“
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.“

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.“
„There have been a number of proposed “geo-engineering solutions” to the problem of climate change over the years.[nbsp] […] One of the latest attempts at carbon-capture or sequestration involves the chemical properties of an appropriately named olive-green mineral: Olivine.“
„Touting „sci-fi climate solutions“ – untested technologies not really scalable to the dimensions of our climate change crisis – dangerously delays the day when we actually reduce greenhouse gas emissions.“
„And what happens when countries disagree about what it should be?“
