The article provides a general overview of social sciences perspectives to analyze and theorize climate research, climate discourse, and climate policy. First, referring to the basic paradigm of sociology, it points out the feasible scope and necessary methodology of environmental sociology as a social science concerning the analysis of physical nature. Second, it illustrates this epistemological conception by few examples, summarizing main results of corresponding climate-related social science investigations dealing with the development dynamics of climate research, the role of scientific (climate impact) assessments in politics, varying features and changes of climate discourses, climate policy formation, and knowledge diffusion from climate science. The receptivity of climate discourse and climate policy to the results of problem-oriented climate research is strongly shaped and limited by its multifarious character as well as by their own (internal) logics. The article shows that social sciences contribute their specific (conceptual) competences to problem-oriented research by addressing climate change and corresponding adaptation and mitigation strategies.
