Science-policy Interactions in Climate Change Diplomacy

Scholarly debates about the role of scientists in political and policy processes have become heated over the last decade, especially in the context of climate change. This research theme explores the institutionalized role of scientists and scientific knowledge in the climate regime, cognitive barriers of science ‘consumers’—climate policy makers and diplomats, and more generally, the political influence of science.

  1. How to Design the Global Stocktake – Making or Breaking the International Climate Regime

The Global Stocktake is a new governance process established in the Paris Agreement on Climate Change, the details of which still need to be worked out. Drawing lessons from other international regimes, from the history of the climate regime itself and identifying the goals of the negotiation participants, the project develops a framework for assessing forthcoming design proposals for the Global Stocktake with a view to effectiveness.

This project is supported by an Exploratory Research in the Social Sciences grant of Purdue University’s College of Liberal Arts.

  1. Global Temperature Goals to Avoid Tipping Points? – A Serious Game to Support Serious Decisions

This interdisciplinary project merges a creative knowledge co-production process between scientists and climate diplomats on urgent questions in global climate change governance and a scientific assessment of the effectiveness of this science-policy interaction. We develop a serious game to provide timely decision support for climate negotiators on two connected issues: climate tipping points and global temperature goals. Participating political actors will have the opportunity to (a) deepen their understanding of the cost-impact trade-offs involved in pursuing various temperature goals, in particular with a view to the possibility of passing specific climate tipping points, and to (b) imagine the social-political, economic-technological and environmental futures their collective decisions could create. In addition to engaging global policy makers, the project studise participants’ beliefs concerning the temperature target and measures the impact of the project’s activities on these beliefs. We will observe the long-term effects of the engagement process in the global climate negotiations.

This project is funded by the Andrew W. Mellon Foundation under its Global Grand Challenges Initiative.
