Final Seminar in PhD Training: Planetary Timemakeing

Erik Isberg is a doctoral student in the SPHERE project. His work concerns the scientific construction of a global environment and how planetary timescales were increasingly incorporated into human history and global environmental governance between 1950-1980. As human impact on the environment began to be understood in planetary terms, practices aimed at tracking environmental changes over vast periods of time, such as ice core drilling and pollen analysis, were drawn into the political spotlight. They spoke to more than just the deep past, as they gradually became immersed in the work to predict, visualize and alter the trajectories of the living conditions on the planet. Over the course of a few decades, long planetary timescales had moved into the realm of the governable.
