The dire consequences of a rapidly warming planet were laid bare at COP27, the global climate change negotiations held in Egypt in November 2022. In this podcast, writer Paul Gorman talks to climate scientists Dr Dave Lowe and Hunter Douglas about their views on what needs to be done to forestall runaway temperatures.

Dave is an atmospheric chemist who first measured southern hemisphere carbon dioxide levels at Baring Head near Wellington in the early 1970s. His memoir The Alarmist: Fifty years of measuring climate change was published in 2020. Hunter Douglas is at the other end of his career. Hunter is a PhD candidate in Geophysics at the New Zealand Climate Change Research Institute at Te Herenga Waka—Victoria University of Wellington.
