Reviewing the landscape of literature on solar radiation modification

Solar radiation modification refers to a range of approaches that seeks to limit or reduce global warming by increasing the amount of sunlight reflected to space. It has been highlighted as one of the few known approaches that could deliberately be implemented to cool the earth within a few years. However, the risks associated with the technology are largely unknown and may include uneven cooling, further climate variability, disruptions to the lower and middle stratosphere, acid rain and could reduce incentives to mitigate global greenhouse gas emissions through other (more traditional) means. In this rapid evidence profile, we provide a brief overview of the empirical literature related to solar radiation modification technologies.
