Towards a more democratic climate science?Some years ago, the internet played a crucial role in the incident that was to become known as 'Climategate'. An archive of around 1,000 e-mails that involved scientists at the Climatic Research Unit (CRU) at the University of East Anglia was unlawfully made public.The -gate suffix suggests that the e-mail authors were involved in a scientific scandal, and that anthropogenic global warming was a hoax. The online sphere and mainstream press exploded in subsequent controversy. As an example, it was described inThe Telegraph as "The worst scientific scandal of our generation" Second, studies of scientists' discursive strategies in controversies (Gilbert 1984) indicate that scientists tend to close up instead of opening up when controversies rage, and that they use demarcation strategies to discredit critics and resolve controversies (e.g. Burchell 2007, Michael andBirke 1994). This is an obvious challenge if the goal is socially robust knowledge, because trench-style warfare differs in character from deliberative communication.Mobilizing Sunniva Tøsse's vocabulary of openness and control (2013) these insights could suggest that scientists prefer strategies of control when controversies heat up, and that climate scientists are more interested in achieving 'politically robust' communication.This concept was introduced by Tøsse precisely to address some of the problematic issues with respect to the exercise of control over the reception of scientific information in controversial situations.We want to discuss what happens with the strategies of climate scientists and skeptics when the controversy is played out online.Do we find signs of agora-style democratic deliberation that caters for open scientific debates and the production of more socially robust knowledge, or do we rather find that climate scientists and skeptics seek to maintain control over the production and dissemination of factual arguments and withdraw to their own spheres in pursuit of managing the situation?What do we know about how climate change is debated online?Some literature already exists that might illuminate our discussion.Mike Schäfer (2012) has reviewed more than 100 papers that deal with online climate communication from multiple disciplinary perspectives. A key insight from this study was that climate scientists are actually not the main players in online climate communication.However, some scientists do use the internet, and they do ...
