An IPCC that listens: introducing reciprocity to climate change communication

As the epistemic hand in the UNFCCC’S political glove, the IPCC is charged with furnishing the global dialogues with ‘reliable knowledge’ on climate change. Much has been written about how this body of scientific information can be communicated more effectively to a diverse public, but considerably less so on the role communication might play in making the IPCC itself more receptive to alternative forms of contribution. Climate change communication remains centred on a unidirectional model that has helped climate science achieve greater public legibility, but so far not explored equivalent channels within institutional thinking for representing public and other non-scientific knowledges. Anticipating a new assessment report and major developments for the Paris Agreement, now is an opportunity to consider ambitious pathways to reciprocity in the IPCC’s communication strategy. Drawing on interdisciplinary insights from social science literatures, we argue that communication is not only inseparable from knowledge politics in the IPCC, but that communication activities and research may prove key avenues for making the IPCC more inclusive. Recognising climate communication as a developed field of study and practice with significant influence in the IPCC, we present a framework for categorising communicative activities into those which help the panel speak with a more human voice, and those that help it listen receptively to alternative forms of knowledge. The latter category especially invites communicators to decouple ‘epistemic authority’ from ‘scientific authority’, and so imagine new forms of expert contribution. This is critical to enabling active and equitable dialogue with underrepresented publics that democratises climate governance, and enhances the public legitimacy of the IPCC.
