Assembling the climate story: use of storyline approaches in climate-related science.

Storylines are introduced in climate science to provide unity of discourse, integrate the physical and socioeconomic components of phenomena, and make climate evolution more tangible. The use of this concept by multiple scholar communities and the novelty of some of its applications renders the concept ambiguous nonetheless, because the term hides behind a wide range of purposes, understandings, and methodologies. This semi-systematic literature review identifies three approaches that use storylines as a keystone concept: scenarios-familiar for their use in IPCC reports-discourse-analytical approaches, and physical climate storylines. After screening peer-reviewed articles that mention climate and storylines, 270 articles are selected, with 158, 55, and 57 in each category. The results indicate that each scholarly community works with a finite and different set of methods and diverging understandings. Moreover, these approaches have received criticism in their assembly of storylines: either for lacking explicitness or for the homogeneity of expertise involved. This article proposes that cross-pollination among the approaches can improve the usefulness and usability of climate-related storylines. Among good practices are the involvement of a broader range of scientific disciplines and expertise, use of mixed-methods, assessment of storylines against a wider set of quality criteria, and targeted stakeholder participation in key stages of the process.
