At a time when science is perceived to be under attack and our planet is facing severe challenges, the role of science journalism in taking on these challenges was a key theme of the 11th World Conference of Science Journalists. But, while policymakers and science leaders are urging journalists to help restore public trust in science, science journalists are concerned about the future viability of their profession in the face of faltering business models in mainstream media.

Keyes [2004, p. 15] says: “In the post-truth era we don't just have truth or lies but a third category of ambiguous statements that are not exactly the truth but fall short of a lie”. In this paper about Hector's and Maui dolphin management in New Zealand, we argue that some scientific knowledge about these species presented and disseminated in ways that equate to this third category and as such may be classed as ‘post-truth type communication’. This generates citizen mistrust in science, scientists and government agencies and inflames conflict among informed stakeholders. We argue trust may be rebuilt by a combination of deliberative approaches to environmental governance, transparency about uncertainties, information gaps and divergent scientific opinions, and reformulation of normal scientific approaches and assumptions to those advocated by post-normal science.

‘Catan’® (1995) is a multiplayer tabletop game with global sales of over 20 million copies. Presented here is an exploration of the steps that were taken in the development of the ‘Catan: Global Warming’ expansion, from prototype to final design. During the playtesting of the game the feedback that we received from a variety of playtesters indicated that the game mechanics (rather than any accompanying story) were an effective and elegant way of developing dialogue around a specific topic, in this instance global warming. We conclude that in order to develop such a game, consideration must be given to: the accessibility of the game, the game literacy of the proposed players, the playtesting of the game mechanics, the peer review of the scientific content, and the extent to which the metagame (i.e. those discussions that take place around and away from the game) is enabled.

Knowing how specific publics understand and experience science is crucial for both researchers and practitioners. As learning and meaning-making develop over time, depending on a combination of factors, creative possibilities to analyze those processes are needed to improve evaluation of science communication practices. We examine how first grade children's drawings expressed their perceptions of the Sun and explore their views of a major astronomical body within their social, cultural and personal worlds. We then examine how the observation of the Sun through a telescope led to changes in graphical representations, and how learning and meaning evolved after several months.

This critical discourse analysis examined climate change denial books intended for children and parents as examples of pseudo-educational materials reproduced within the conservative echo chamber in the United States. Guided by previous excavations in climate change denial discourses, we identified different types of skepticism, policy frames, contested scientific knowledge, and uncertainty appeals. Findings identify the ways these children's books introduced a logic of non-problematicity about environmental problems bolstered by contradictory forms of climate change skepticism and polarizing social-conflict frames. These results pose pedagogical dilemmas for educators, environmental advocates, and communication experts interested in advancing understanding and action in the face of rapid climate change.

Astronomy has been an inherently visual area of science for millenia, yet a majority of its significant discoveries take place in wavelengths beyond human vision. There are many people, including those with low or no vision, who cannot participate fully in such discoveries if visual media is the primary communication mechanism. Numerous efforts have worked to address equity of accessibility to such knowledge sharing, such as through the creation of three-dimensional (3D) printed data sets. This paper describes progress made through technological and programmatic developments in tactile 3D models using NASA's Chandra X-ray Observatory to improve access to data.

The Intergovernmental Panel on Climate Change (IPCC) proceeds on the assumption that scientific consensus is a tool for successful climate communication. While ‘speaking with one voice’ has contributed to the Panel's success in putting climate change on the public and political agenda, the consensus policy is also contested, as our literature analysis (n=106) demonstrates. The arguments identified thereby inform a survey of climate scientists (n=138), who are the ones responsible for realising the policy. The data indicate moderate support for the consensus policy but significantly more in traditional climate sciences than in social sciences, life- and geosciences.

Advances in 21st century genetic technologies offer new directions for addressing public health and environmental challenges, yet raise important social and ethical questions. Though the need for inclusive deliberation is widely recognized, institutionalized risk definitions, regulation standards, and imaginations of publics pose obstacles to democratic participation and engagement. This paper traces how the problematic precedents set by the 1975 Asilomar Conference emerge in contemporary discussions on CRISPR, and draws from a recent controversy surrounding field trial releases of genetically modified mosquitoes to explicate the ways in which these precedents undermine efforts to engage publics in decisions at the science-policy interface.

This study investigates how different segments of the public, with varying degrees of interest in S&T, could formulate opinions on a broader vision and the role they think STI should play in Japanese society through 2020 (Tokyo's Olympic and Paralympic year) and toward 2030. We conducted nine inclusive public engagement activities. Results indicated that the broad public opinions did not completely overlap with officials' opinions, a value of “open and appropriate” was mainly found from the unengaged public, and the visions and values based on their opinions could well be incorporated into the official document. Engaging the disinterested in S&T remains an issue.

Today, science and politics are in a complex status of reciprocal dependency. Politics is dependent on scientific expertise in order to adequately address highly complex social problems, and science is fundamentally dependent on public funding and on political regulation. Taken together, the diverse interactions, interrelations and interdependencies of science and politics create a heterogenous and complex patchwork — namely, the science-policy interface. The societal relevance for phenomena such as scientific policy advice, science governance or (politically fostered) science communication have been amplified by the developments of digitalisation and now call for new approaches to clarify the ambiguous relationships within the science-policy interface. This special issue aims to provide a platform for researchers to address communication at the intersection of science and politics from different angles. The research presented in the special issue, thus, aims to reduce the contingency of science-policy communication in its various dimensions and looks to spur further investigations into the science-policy interface.
