Why is the sky blue? A new question for political science.

The future of political science in this crucial century requires that it (i) adopt the contemporary scientific paradigm, (ii) open itself to pluri-, inter- and transdisciplinarity, and (iii) redefine the main political actor, ourselves, in light of post-anthropocentric and relational turns. A theoretical revolution to a post-normal and eco-political science is needed and, through the influence of new fields such as sustainability science, is probably already in motion. In the Anthropocene, it implies paying attention to biological links that once seemed extemporaneous. And this is when we realize that the sky has become co-vulnerable. We may actually be at risk of losing blue sky through anthropogenic actions, including global warming or solar geoengineering. Politics will be crucial in determining whether or not to preserve its blue, and everything that goes with it. The article explores, through the answer to the blue question, this new super-wicked problem to illustrate the stated objectives for political science and the need to apply them. The proposals that have emerged from this also provide a new framework for Clean Air strategies for blue skies that are being developed at international and national levels. [ABSTRACT FROM AUTHOR]
