Leaking the IPCC: A question of responsibility?

In August 2021, while the world was grappling with the release of the IPCC WGI report, a group of activist scientists called Scientist Rebellion leaked parts of the Working Group III contribution to the Sixth Assessment Report (AR6) prior to intergovernmental approval. Although Scientist Rebellion are not the first to leak an IPCC report, they are the most vocal leaker with a particular political agenda: to generate disruptive climate action by curtailing the carefully orchestrated intergovernmental process of the IPCC. I take this case of science in activism involving the IPCC interface as an example to examine the increasingly intricate relationship between science, activism and responsibility. The salient sense of urgency around climate action, the growing prevalence of the climate crisis narrative in both public and scientific spheres, and the increased policy‐relevance of science‐policy interfaces put strong pressures on (climate) scientists that need to be disentangled to be understood without premature judgment. I show that the leak is symptomatic of the novel responsibility to act(ivism) scientists are increasingly confronted with and I highlight some of the tensions that come with this responsibility. Emphasizing the centrality of the question of responsibility in, and of, science, I discuss the (ir)responsibility of leaking IPCC draft materials. I end on a call for more interdisciplinary attentiveness to the nexus of science, activism and responsibility and the cases in which they become entangled.
