The United States is eyeing a controversial tool to counter : Solar radiation management (SRM), whichinvolves reflecting a small fraction of sunlight into space.
In areport released June 30, 2023, the White House stated that public or private actors could carry out activities such as injecting aerosols and brightening marine cloudsto reflect more sunlight into space.
The academia, philanthropy, and the private sector have examined preliminary applications of Climate intervention techniques, such as stratospheric aerosol injection and marine cloud brightening.
The scientific dimensions of SRM involve new and continued ground-based, airborne, and space-based observations and improving global modelling of SRM approaches and scenarios. They can help in the understanding of the physical processes and outcomes associated with SRM.
