Right now, there's a heatwave in one of the coldest parts of the planet. So sound recordist Mark Michel travelled to the bottom of the world and brought back the unbelievable sounds of the melting Antarctic continent. He talks with Eloise about his big adventure, and about the challenges of raising awareness of climate change.

The One Hot Minute podcast is a companion series to Stuff's One Hot Minute video series, in which climate-change change-makers are given just 60 seconds to talk about climate change. Then in this podcast we dig deeper into that idea. To watch the videos, see www.stuff.co.nz/onehotminute. The series is part of Stuff's Forever Project.
