Solar radiation management
Solar radiation management (SRM) projects (proposed and theoretical) are a type of climate engineering which seek to reflect sunlight and thus reduce global warming. Proposed examples include the creation of stratospheric sulfate aerosols. They would not reduce greenhouse gas concentrations in the atmosphere, and thus do not address problems such as ocean acidification caused by excess carbon dioxide (CO2). Their principal advantages as an approach to climate engineering is the speed with which they can be deployed and become fully active, as well as their potential low financial cost. By comparison, other climate engineering techniques based on greenhouse gas remediation, such as ocean iron fertilization, need to sequester the anthropogenic carbon excess before any reversal of global warming would occur. Solar radiation management projects can therefore be used as a climate engineering ""quick fix"" while levels of greenhouse gases can be brought under control by greenhouse gas remediation techniques.
