How should environmental political theorists deal with environmental science? The question has acquired a new urgency with the rise of the Anthropocene, a geological-cum-ecological concept received with skepticism by many political theorists. In part, this is due to the notion that there is an “oficial” version of the Anthropocene that comes out already linked to a set of normative and policy prescriptions for dealing with climate change and the other manifestations of the new epoch, i.e. a managerial approach that is capitalist-friendly and technologically trigger-happy. However, this in turn reflects deep-seated suspicions about scientific findings and the way in which they are “produced”. This paper will reflect on this topic in the framework provided by the Anthropocene, arguing that a clear demarcation is needed between the scientific and the sociopolitical inquiry, whereupon the former provides the latter with findings to be discussed and processed in a sociopolitical fashion -whereas scientists should refrain from making normative or policy prescriptions or, if any, should make them explicitly. After all, environmental political theory would not exist without environmental sciences. The debate on the beginning of the Anthropocene will help to make this point.
