Australian scientist and conservationist Tim Flannery is on a global search for genuine leadership on climate change. Interviewing everyone from CEOs to politicians and activists, he poses the question: Do we have what it takes to get out of this mess? This investigation traces Tim’s journey back from his early days as a palaeontologist piquing his interest in climate change, to his tireless – but fruitless – efforts at the 2009 Copenhagen COP, before returning to the 2021 Glasgow COP. His ongoing fight for change brings with it geopolitical troubles, adversity from a fossil fuel industry reluctant to change, as well as personal attacks from deniers and right-wing media.
