GIGA Involved in the CLICCS Cluster of Excellence: New Funding for Climate Research in Hamburg

On 22 May 2025, the German Research Foundation (DFG) and the German Council of Science and Humanities (WR) announced their decision on the future Clusters of Excellence in Germany. Among the 70 selected clusters is the University of Hamburg’s “CLICCS - Climate, Climatic Change, and Society,” in which the GIGA plays a key role. Funding will begin on 1 January 2026 and run for seven years.


  • CLICCS II will continue and further develop the successful work of the previous cluster. More than 200 scientists from 16 disciplines are working closely together to understand the interactions between climate change, social development, and political trajectories.

    The GIGA contributes its expertise to various research projects. Under the leadership of Prof. Dr. Miriam Prys-Hansen, for example, its researchers are working on topics such as the investigation of the social and political dynamics behind climate policy or the question of how ideas of future development (“climate futures”) are created, communicated, and negotiated in various arenas – from local contexts to global discourses.

    With its participation in CLICCS, the GIGA underlines its role as a leading institute in interdisciplinary research on global challenges. Close cooperation with partners such as the University of Hamburg, the Max-Planck-Institute for Meteorology, and the German Climate Computing Center (DKRZ) makes it possible to formulate scientifically sound decision-making aids for politics and society and to shape the contours of social discourse. We look forward to continuing our close cooperation with the University of Hamburg and our non-university partner institutions.

    The Excellence Strategy of the federal and state governments provides around EUR 539 million annually for the 70 approved clusters. Selection was based on an international review process that involved the input of over 400 experts.

    Climate, Climatic Change, and Society (CLICCS), Cluster of Excellence / Universität Hamburg

    The Cluster of Excellence “Climate, Climatic Change, and Society” (CLICCS), based at Universität Hamburg, is guided by the overarching question: "Which climate futures are possible and which are plausible?" The GIGA contributes to the cluster with its research on climate governance, the social construction of climate futures, and the interactions between climate change and conflict.
