Joëlle Gergis (@joellegergis) is an award-winning climatologist and writer based at the Australian National University. Her latest book, Humanity's Moment: A Scientist's Case for Hope, is a passionate and unsparing look at what has been lost but also what can still be saved - and why should still have hope. Dr Gergis draws on her experience as the lead author of Working Group 1, of the IPCC's latest assessment report (AR.6), as well as on her own experiences of facing up to the scale of the challenges posed by a rapidly warming natural world. She speaks to Edward Robinson.
