Schäfer, Stefan; et al. (2013): Field tests of solar climate engineering

Schäfer, Stefan; Irvine, Peter J.; Hubert, Anna-Maria; Reichwein, David; Low, Sean; Stelzer, Harald et al. (2013): Field tests of solar climate engineering. In Nature Climate change 3 (9), p. 766. DOI 10.1038/nclimate1987.

"All of these proposals acknowledge a need for some form of governance, such as national oversight by funding bodies, but they also share a common supposition that smallscale testing should proceed even in the absence of further international agreement. However, there are strong reasons to refrain from such testing until some form of international cooperation on climate engineering has been established."

MacCracken, M. C.; et al (2013): Climate response to imposed solar radiation reductions in high latitudes

MacCracken, M. C.; Shin, H.-J.; Caldeira, K.; Ban-Weiss, G. A. (2013): Climate response to imposed solar radiation reductions in high latitudes. In Earth Syst. Dynam. 4 (2), pp. 301–315. DOI 10.5194/esd-4-301-2013.

"Model simulations in which solar insolation was arbitrarily reduced poleward of 51, 61, or 71° latitude in one or both hemispheres not only cooled those regions, but also drew energy from lower latitudes, exerting a cooling influence over much of the particular hemisphere in which the reduction was imposed. The simulations, conducted using the National Center for Atmospheric Research's CAM3.1 atmospheric model coupled to a slab ocean, indicated that high-latitude reductions in absorbed solar radiation have a significantly larger cooling influence than solar reductions of equivalent magnitude spread evenly over the Earth."
