Nagase, H.; Kinnison, D. E.; Petersen, K.; Vitt, F.; Brasseur, G. P. (2015): Effects of Injected Ice Particles in the Lower Stratosphere on the Antarctic Ozone Hole. In Earth's Future, pp. n/a. DOI 10.1002/2014EF000266.

"In this paper, we suggest a geo-engineering approach that will remove substantial amounts of hydrogen chloride (HCl) from the lower stratosphere in fall and hence limit the formation of the Antarctic ozone hole in late winter and early spring. HCl will be removed by ice from the atmosphere at temperatures higher than the threshold under which polar stratospheric clouds (PSCs) are formed if sufficiently large amounts of ice are supplied to produce water saturation."

"The danger of this approach is that the capitalist governments that are already extremely reluctant to spend any significant money on reducing warming will jump at climate engineering as a cheap alternative. Going down this road could, potentially, be almost as dangerous as global warming itself. Removing the fundamental cause of the problem means removing the profit-driven capitalist market system. The longer this task is delayed, the worse will be the prospects for the environment."

On climate economy including CE. "We know enough about geoengineering to know that it could in fact work, in the sense of helping to lower average temperatures. We don’t know the full costs. As an economist, looking at this, what I would say is that you ought, at the very least, come up with a proper cost-benefit analysis."
