Podcast - Dust Storm Diplomacy

In March 2021, Seoul woke up under a thick yellow haze - the worst dust storm in a decade. South Korea blamed China, who promptly blamed Mongolia.

The Transnational Politics of Dust Storms Between China and Mongolia, and Prof Andreas Baas, a physical geographer with expertise in desertification and land degradation.Together, they unpack how dust storms stir up more than sand - touching on nationalism, environmental diplomacy, and the politics of green solutions - questions that resonate far beyond the Gobi Desert.You can read more about this topic here This is a public episode.

We've already reached 1.5°C.This week Esau asks: what does 'too hot' actually mean? What will happen to the people who live in these areas? And what might be done to help combat the impacts?Joining him are Dr Tom Matthews, lead author of the study and Senior Lecturer in Environmental Geography, and Aditya Pillai, who is a doctoral researcher in King’s India Institute, a Visiting Fellow at the Sustainable Futures Collaborative, New Delhi, and author of a recent report investigating India’s readiness for the extreme heat of a much, much hotter world.
