Earlier this year the National Research Council of the US National Academy of Sciences released a pair of reports on two strategies of climate intervention in order to reduce the risks of negative impacts from climate change. The first of the pair of reports discusses the opportunities and challenges in carbon capture and long-term, safe sequestration. The second report discusses several approaches to reflecting sunlight to cool Earth, including the risks, time scales, costs, and socio-economic, and political considerations. The primary conclusion from these pair of reports is that mitigation and adaptation are still our best choices in terms of cost and low risk for reducing harmful effects from climate change: there is no "silver bullet." Given that the polar regions of the planet are the most sensitive to climate change, the reports also touched on the potential for regional climate intervention. The majority of the methods that are currently under discussion and for which there is a body of peer-reviewed research would have global impacts, with but few exceptions.
