Tipping points

In series one, podcast host Peter Knapp, an Imperial research postgraduate studying indoor air pollution, speaks with scientists from multiple disciplines who are concerned about the current state and future of the climate and life on Earth.

In series two, Peter focuses on other aspects of society that have a role to play in raising awareness about climate and ecology. Exploring why a newly qualified pilot would quit before paying back a substantial aviation college debt, and what would make someone stop work as a police officer and instead become an activist.

In each series Peter's guests share their personal stories, explaining what led them to be interested in the environmental and ecological crises. They discuss their opinions on public communication, politics, divestment campaigns, having children, Greta Thunberg, travel, carbon footprints, what they hope to see in the future and much more.

Both series are available to listen to on Podbean, Spotify, Audible, Amazon music, YouTube and TuneIn.
