This perspective presents the concept of a climate change scenario service and outlines how to make scenarios more accessible to a broader audience of societal actors and decision makers. The wide-ranging concept of a climate change scenario service presented in this paper is designed to enhance the salience, credibility and legitimacy of scenarios.

The authors present the SENSES toolkit, which implements central components of the wide-ranging service concept. The toolkit focuses on mitigation scenarios, as these are strongly under-represented in the arena of climate services, but also contain material for impact projections and adaptation scenarios. The toolkit represents an important step for research in this area.
