Disputed climate science in the media: do countries matter?

This article presents findings from a large-scale newspaper analysis of climate change discourses in four developed countries, using corpus linguistics methodology. We map the discourse over time, showing peaks and troughs of attention and explaining their causes. Different connotations of common terms such as global warming and climate change in different countries are analysed. Cluster and key-word analysis show the relative salience of specific words and word combinations during crucial periods. We identify main claims makers and the relative visibility of advocates and sceptics. The main finding is that former are far more prominent in all countries. We also look at the coverage of 'climategate'. Finally, we make reference to existing theoretical frameworks.

COVID and Climate: Similarities and differences.

The cases of COVID-19 and climate change highlight the central role of scientific research which supposedly guides political decision-making. Models and scenarios assume a central role. However, science cannot tell us what to do. While it provides important facts and metrics, uncertainties remain and decisions are based on considerations pertaining to fundamental values. Apart from these similarities, my aim is to emphasize some significant differences. They relate to policy goals, international cooperation, data and metrics, values, and the time horizons involved.

The Problem of Expertise in Knowledge Societies.

This paper puts forward a theoretical framework for the analysis of expertise and experts in contemporary societies. It argues that while prevailing approaches have come to see expertise in various forms and functions, they tend to neglect the broader historical and societal context, and importantly the relational aspect of expertise. This will be discussed with regard to influential theoretical frameworks, such as laboratory studies, regulatory science, lay expertise, post-normal science, and honest brokers. An alternative framework of expertise is introduced, showing the limitations of existing frameworks and emphasizing one crucial element of all expertise, which is their role in guiding action.
