The Center for a Sustainable University at the University of Hamburg has approved funding for the new research project “Sustainable Food Choices as Politics and Lifestyle”, which will start in spring 2018. The project investigates the drivers of food choices and how changing discourses, norms and attitudes about food relate to actual patterns of food consumption: What drives food choices and how are they influenced by ideas and discourses related to more sustainable lifestyles? This question will be tackled in a comprehensive interdisciplinary approach that looks at both, discourses about food and the everyday practices of food consumption. The researchers will analyze local media outlets and conduct surveys and experiments (in the WISO research lab).
Project board members: Michael Brüggemann (speaker), Jannis Androutsopoulos, Imke Hoppe, Katharina Kleinen-von Königslöw, Stefanie Kley, Grischa Perino and Anke Strüver
Project coordinator / researcher: Dr. Radhika Mittal
The paper “Echo Chambers of Denial: Explaining User Comments on Climate Change” was published in Environmental Communication. The study identifies factors that foster comments that are sceptical or supportive of basic assumptions of anthropogenic climate change, drawing on online news in the US, the UK, Germany, India, and Switzerland. The results show that users adapt to the dominant opinion within the respective media outlet: user comment sections serve as echo chambers rather than as corrective mechanisms. Climate change denial is more visible in user comment sections in countries where the climate change debate reflects the scientific consensus on climate change and user comments create niches of denial.

The paper “From “Knowledge Brokers” to Opinion Makers: How Physical Presence Affected Scientists’ Twitter Use During the COP21 Climate Change Conference” was published in the International Journal of Communication. This study investigates the 2015 United Nations Climate Change Conference summit and examines scientists’ social media use by analyzing “digital traces” that scientists left on social media during the summit. Using geolocated tweets, we compare the Twitter use of scientists who attended the conference with those who did not. Combining automated, quantitative, and qualitative content analysis, the study shows how scientists participating in the conference provided live reporting and formed a transnational network. Scientists at the conference and elsewhere engaged in political advocacy, indicating a shift toward a new pattern of hybrid science communication, which includes characteristics that have formerly been attributed to journalism and advocacy.

Review of Twitter communication on climate change in 2017: Which events triggered tweets about climate change and to which domains do these tweets link to?
by Ines Lörcher

Still – and this year even more – Donald Trump’s statements and action trigger most Twitter communication on climate change. This year’s highest peaks of attention were related to climate political events in the USA. Most tweets were published on 2nd June 2017, one day after US-president Donald Trump declared that the USA will quit Paris climate agreement.
