[From Executive Summary] …[M]ajor institutional and political hurdles dim future prospects for controlling [greenhouse gas] emissions. While adaptation to climate change can accomplish much, flawed institutions are likely to limit its efficacy.

Solar radiation management (SRM) appears to promise at least some capacity to offset the warming caused by the rising atmospheric GHG concentrations. SRM would seek to enhance and manage physical processes that currently reflect sunlightback into space. For example, most researchers have envisioned implementing this concept by adding to the layer of sulfuric acid that is already present in the lower stratosphere. All else remaining equal, global mean temperatures would fall even though GHG levels would not; the Intergovernmental Panel on Climate Change estimates that physical processes such as these already offset about 40 percent of global warming. By lessening the rise in temperature, SRM might lessen some of the risks of global warming…
