"All of these proposals acknowledge a need for some form of governance, such as national oversight by funding bodies, but they also share a common supposition that smallscale testing should proceed even in the absence of further international agreement. However, there are strong reasons to refrain from such testing until some form of international cooperation on climate engineering has been established."
