Geoscience is central to all our futures. Whether it’s the energy transition, clean water, feeding the planet, mitigating climate change, or building sustainable cities, the world needs geoscientists. But is the discipline of geoscience fit for purpose? In this podcast, well known broadcaster Professor Iain Stewart - along with colleagues Cam McCuaig and Neil Evans from the resources company BHP - talk to "thought leaders" in the field of geoscience, to discover their vision for the future of the discipline. How does geoscience reinvent itself for the great societal challenges of the 21st century? This is a podcast that grew out of a Unesco research project exploring the relationship between geoscience and the UN's sustainability goals. It is intended as a showcase for creative thinking about the future of geoscience.(As a consequence of Covid lockdowns, all the interviews were conducted via video conference and the audio quality sometimes reflects this.)
