This research note presents the results of a content analysis of 234 letters to the editors that discuss evolutionary theory and were published in American newspapers. We find that letters to the editor both support and hinder the cause of teaching evolutionary theory in American secondary schools. On the one hand, anti-evolutionary theory messages are marginalized in the letters section. This marginalization signals a low level of legitimacy for creationism. It might also contribute to the sense of tension that sustains creationist identities. On the other hand, relatively few letters explicitly note the fact that scientists or the scientific community accept evolution. Interestingly, the obscuration of the scientific community’s support for evolutionary theory occurs both in letters supporting and opposing evolutionary theory.

The effects of news media on public opinion about global warming have been a topic of much interest in both academic and popular discourse. Empirical evidence in this regard, however, is still limited and somewhat mixed. This study used data from the 2006 General Social Survey in combination with a content analysis of newspaper coverage of the same time period to examine the relationship between general news climate and public concern about global warming. Results showed a pattern of political polarization, with increased coverage associated with growing divergence between Democrats and Republicans. Further analysis also showed evidence of reactivity in partisan response to coverage from different news outlets. These findings point to a particular form of politically motivated, biased processing of news information.

The mass media has a fundamental role to sustain an informed citizenry as a prerequisite for democratic politics. It is, therefore, vital that an evidence-based approach is used when reporting on climate change. Yet, multiple and arguably irreconcilable tensions exist between science and mass media. For example, as media workers are trained to provide a ‘balanced’ approach, this can result in bias in climate change reporting. Additionally, various industry-related pressures mean that mainstream journalists often have limited resources and time to check the accuracy of their climate news stories with researchers. Such tensions and media coverage of alleged climate research misconduct formed the basis of a survey we have developed for an interface group of researchers and journalists who have a vested interest in climate science. The aim of this survey is to compare their attitudes on the performance of the media as a channel of climate change information. The survey was conducted in mid-2010, with responses from journalists and researchers who attended international fora for science–media interface and research integrity discussions, or accessed the survey via an international climate research programme website. Survey findings reveal, contrary to tensions described in the existing literature, a mutual intelligibility and general trust between this core group of journalists and researchers, who have a vested interest in evidence-based climate science reporting. We argue that scientifically informed interface journalists, by collaborating with scientists, can help influence mainstream journalists to better inform the public about the urgency for society to overcome the diabolical climate challenge.
