Leibniz institutions launch initiative “Integrated Earth System Research"

Humanity’s interference with the Earth system, which has evolved over millions of years, is increasing rapidly – and with it the open questions regarding its impacts on Earth and humankind are growing. Climate change mitigation and adaptation to unavoidable climate change alone already require considerable efforts across several policy and economic sectors. How to deal with the even more extensive environmental problems of the Anthropocene – the current epoch of the Earth in which humans have gained a strong influence on the Earth system?

Scientists from numerous Leibniz institutions have now addressed this question at the virtual conference “Integrated Earth System Research – Challenges, Approaches and Impacts”. In view of the enormous dimension of the problem, experts not only from climate, biodiversity and ocean research participated, but also from global economic research, spatial research and international peace and conflict research, among others. As a result of the two-day discussion, it became clear that so far there are hardly any adequate, integrative approaches to scientifically deal with such a complex phenomenon. It is true that there is extensive knowledge about individual processes of change. However, this knowledge is still insufficiently interconnected and usable.

Against this background, the participants of the conference have launched an initiative for “Integrated Earth System Research”. Together with partners from Germany, Europe and other countries, they will investigate the Anthropocene in an unprecedented coordinated and interdisciplinary manner. An important goal is to also develop solutions in the course of research with actors from politics, business and civil society.

 “With this initiative, we are bringing together global model simulations from very different disciplines and placing them in the context of concrete societal needs and possibilities for action for the first time,” says Jochen Schanze, the conference chair. “At the moment, our research mission may seem like a vision of a moon landing in the 1960s. However, all participants agree that the scale and speed of Earth system change urgently requires such an initiative.” Dieter Gerten from the Potsdam Institute for Climate Impact Research PIK adds: „We know a lot about climate change and its impacts. However, the complex feedbacks in the Earth system entail risks that are to be studied – in order to minimize them and thus secure our future.“

In the coming months, a research platform will therefore be established step by step. The Leibniz institutions see themselves as initiators, while the platform will be open to all interested scientists. For an initial pooling of resources, numerous Leibniz institutions have already joined forces to form the Leibniz Research Network “Integrated Earth System Research”. The expertise of this network ranges from the observation and modelling of Earth system processes to economics, political and social sciences. The research museums, which are also involved, play an important role in communicating the results in addition to their scientific work.
