A second research thrust is focused on exploring potential technical
approaches for injecting suitable materials with an optimal distribution and
in a cost-effective manner (McClellan et al. 2011). Because of concerns about
the potential impacts from eld research into, much less actual creation of,
a stratospheric aerosol approach, consideration is also needed concerning
the strengths and weaknesses of various climate engineering governance
structures (Rayner et al. 2009; Asilomar Scientic Organizing Committee
2010), including the potential for and ramications of an individual coun-
try (or even an ...
