Summary

Sea ice coverage hit a recording-breaking low in the Antarctic this week, but what does this mean for the rest of the world? Why is the region so difficult to predict? And what could further changes in climate mean for the South Pole? Often the Arctic dominates conversations around polar warming but this week, with the help of climate modelling expert Tamsin Edwards, Kings College London, we’ll be tackling these questions and more. We’ll hear from British Antarctic Survey researcher Nadia Frontier, a marine biologist spending the summer at Rothera research base in the Antarctic. We join her as she traverses snow and ice to study the inhabitants of Adelaide island and the surrounding waters. Rachel Tilling from the Cryospheric Sciences Lab at NASA’s Goddard Space Flight Center helps us explore the continent from a different vantage point, explaining her work using satellite data to understand sea ice thickness. And climate reporter Georgina Rannard takes us through an artistic interpretation of polar sounds, Dr Geraint Rhys Whittaker uses underwater microphones to capture the impact of human activity on polar wildlife. Presenter: Victoria Gill Producers: Julian Siddle and Emily Bird BBC Inside Science is produced in collaboration with The Open University.
