PIK was founded in 1992 by Hans Joachim Schellnhuber, who became the institute's first director. In 2018 he was succeeded by two joint directors—the climate economist Ottmar Edenhofer, and Earth scientist Johan Rockström, formerly director of the Stockholm Resilience Centre.[1] About 400 people work at the institute that is located on Potsdam's historic Telegrafenberg.[2] Researchers from the natural and social sciences analyze the Earth system, assess climate risks and develop policies and solution pathways towards a manageable climate future.[citation needed]
