The series is supported by the Graduate School of Geosciences (contact: Dr Karin Boessenkool)

The aim of this lecture series

The aim of the lectures is to achieve a deeper understanding of current developments and larger trends across the spectrum of the geosciences that affect our society. All topics will be discussed in a broader societal context.

The series is open to everyone in Cologne Geosciences, students and university staff and to members of the regional geo-alliance Geoverbund ABC/J.

Studium Integrale

Students from across the university can partake in the module "Future Earth" offered as a part of Studium Integrale (details are available on the webpages of the Professional Center).

The initiators

This series was initiated and is co-organised by the GSGS Debate Club, a bottom-up initiative of doctoral student members of the Graduate School of Geosciences.
