Abstract
We previously (here) discussed the challenges associated with decision-making in the framework of the radical uncertainty introduced by climate change. We introduced scenarios as a way to break from deterministic representations of the future and to guide decisions. We nonetheless saw that this approach has its own limits. In this article and the following ones, we will cover the reasoning behind robust decision making. These articles are based on the book I recently published with my co-authors on the decarbonation of the economy.
