Until now, such options have rarely been examined in a comprehensive manner. Rather, insofar as this has been done, research focused on one or the other, rather than considering a portfolio contribution and, more often, has taken a sectoral approach that looks at the options germane to the agriculture or energy sectors, but not in relation to climate change. Arguing for the need for a wider lens, the current article aims to understand the kinds of couplings and linkages most germane for the effectiveness of a particular option. In specific, we employed a novel dataset garnered from a large expert-interview exercise ( *N* = 125) to conceptualize and consider crucial couplings to solar radiation management and carbon dioxide removal at many levels (across different sectors, differing dimensions of sustainability, productive or destructive impacts, and direct and indirect relationships). Our analysis thereby provides insights into the understanding of climate transitions by explicitly considering the most salient couplings in general as well as how, and to what extent, the various options relate to each other, as a portfolio for climate intervention, and together to climate mitigation and adaptation.

Note: Bubbles are sized to reflect their prominence across the set of experts, regarding how frequently they were mentioned. Placement is undertaken to highlight conceptual similarities between categories, but without indicating any assessment of importance, or linking potential couplings to a specific class of technologies. *Source: ScienceDirect* -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
