We present narrative descriptions of future societal development associated with the shared socioeconomic pathways. We describe the methods used to develop the narratives and how they produce particular combinations of challenges to mitigation and adaptation. The narratives describe plausible future changes in demographics, human development, economy, institutions, technology, and environment. The narratives span an uncertainty space in terms of socioeconomic challenges to adaptation and mitigation of climate change. The narratives relate to Sustainability, Regional Rivalry, Inequality, and Fossil-fueled Development, and a Middle of the Road pathway.
