Last episode, we talked about how we got to where we are now with climate change, but do we even know what’s going on with climate change right now? In this episode we’ll talk about what tipping points we’re approaching, how and why we’re still struggling to gain momentum toward action on climate change, and what difference it would make if carbon dioxide was a brown smelly substance.

To figure all of this out, we talked to a mathematician, Emily Shuckburgh, an engineer Hugh Hunt and a psychologist, Sander van der Linden. 

Along the way, we discuss solutions like geoengineering, creating a fake news ‘vaccine’ and opportunities for businesses to be more transparent about how their activities contribute to climate change.

Professor Sander van der Linden (@Sander_vdLinden)

Sander van der Linden is Professor of Social Psychology in Society in the Department of Psychology at the University of Cambridge and Director of the Cambridge Social Decision-Making Lab. His research interests center around the psychology of human judgment, communication, and decision-making, including social norms and networks, attitudes and polarization, reasoning about evidence, and the public understanding of risk and uncertainty. He is especially interested in a) the social influence process and how people gain resistance to persuasion through inoculation and b) how people form (mis)perceptions of the social world, including the emergence of social norms in shaping human cooperation and conflict in real-world collective action problems such as climate change and the spread of fake news and misinformation. 

His research is regularly featured in the popular media, including outlets such as the New York Times, the BBC, CNN, The Economist, NPR, the Washington Post and Time Magazine.
