Cymene and Dominic talk fake news and our alleged 'post-truth' condition and then (19:13) we are fortunate enough to welcome to the podcast distinguished Harvard historian of science Naomi Oreskes who—together with her collaborator Erik Conway—has been drawing attention to disinformation campaigns for decades. We talk about their legendary book Merchants of Doubt (http://www.merchantsofdoubt.org) and Naomi shares her opinions about the current manipulation of public opinion and what impact social media and the Internet have had. We talk about journalism’s reliance on “two sides” reporting and how that has contributed to exaggerating the facticity of climate denial. We discuss how her collaboration with Erik originated and how their most recent book The Collapse of Western Civilization (Columbia U Press, 2014) began as something of an accident. Then Naomi shares her thoughts on how to persuade people that climate change matters, especially when they are convinced that climate discourse is being used as a pretext to expand governance. She explains why she thinks satire and science fiction can help the cause and we reflect on why partnership between the human sciences and the natural sciences is so important right now even though we still need to work to balance realism and relativism. Finally, we talk about why scientists need to talk about climate change in the present tense and why we all need to articulate the stakes of climate change in an economic register that people seem to be willing to listen to.
