If efforts to control greenhouse gas emissions do not succeed in combating global warming, some scientists and policy makers may consider geoengineering the climate, even though this could be a risky strategy with potential drawbacks. One geoengineering option is solar radiation management, which involves adjusting the amount of sunlight reaching the planet through one of several possible methods, including injecting sulfur into the stratosphere to block incoming sunlight, putting mirrors in space to reflect sunlight, or injecting sea salt into the air above the oceans to increase the reflectivity of clouds. All of these methods could potentially have a cooling effect, but the regional climate effects and effects on precipitation patterns could differ.
