CHAPTER FIFTEEN #SolarRadiation Management For over 45 years, proposals for deliberate, large-scale manipulation of Earth’s environment—or #geoengineering (see Box 15.1 and Figure 15.1)—have been put forward as ways to potentially offset some of the consequences of #climatechange For example, #whiteningclouds #injectingparticles into the #stratosphere or putting #sunshadesinspace could #increaseEarthsreflectivity thereby reducing incoming #solarradiation and offsetting some of the warming associated with increasing #GHG concentrations. Although few if any voices are promoting geoengineering as a near-term option to limit the magnitude of climate change, the concept has recently been gaining more serious attention as a possible backstop measure to be used if traditional strategies to limit emissions fail to yield significant #emissions reductions or if climate trends become disruptive enough to warrant extreme and risky measures. Questions decision makers are asking, or will be asking, about solar radiation management and other geoengineering approaches include the following: Can the negative impacts associated with increasing #atmosphericgreenhousegas ( #GHG ) concentrations be reduced or offset by intentionally intervening in the climate system? If so, how? What undesirable, unintended consequences might result from such interventions? How could these consequences be anticipated or detected? Who should decide, whether, when, and how to intentionally intervene in the climate system? What institutional mechanisms would be needed to initiate, carry out, monitor, and respond to the impacts—foreseen and unforeseen—of such an effort? Which types of interventions might be most socially acceptable and what frameworks for evaluation, governance, and compensation should be used?
