This podcast complements the University’s Teaching Matters blog, and invites students and staff to engage in topical conversations. The first three episodes accompany the Teaching Matters mini-series on social responsibility and sustainability. In these episodes, University of Edinburgh staff and students debate how sustainability and environmental concerns are being tackled in today’s university.  In this second episode, we continue the conversations from Episode 1 on climate change, which explore if students are facing climate optimism or climate fatalism in the classroom. In this episode, our guest host, masters student Polly Wells, asks her fellow students, Ryan Gilmour, Ellie Ashton and Emily Bankert, about the roles of teachers and students in tackling climate change through teaching and learning.
