This episode explores the life and impact of a pioneering polar ice scientist Dr. Peter Wadhams, renowned for decades of groundbreaking research in the Arctic and Antarctic. The discussion traces the scientist’s remarkable career, from transformative early expeditions through their leadership in major institutions, and details how direct exploration and scientific passion have advanced our understanding of sea ice, climate feedbacks, and the rapidly shifting polar environment. Stories from harrowing submarine missions and international voyages illustrate both the dangers and the unique discoveries made at the frozen edges of the planet.
This video was recorded on July 30th, 2025, and published on September 9th, 2025, and represents the opinions of the discussion participants.
Throughout the dialogue, the conversation delves into the accelerating loss of polar ice, the unpredictability of climate feedback systems, and the global consequences of shrinking sea ice and thawing permafrost. Key scientific concepts—such as methane release, snow cover loss, and the interplay of physical systems—are explained in an accessible manner, while the evolving nature of climate science itself is emphasized. The episode discusses not only the scientific findings but also the personal motivations and philosophy that drive a lifetime of exploration and research in extreme environments.
The discussion expands to the challenges of science communication, the vital role of education, and the lifelong collaboration between explorers, researchers, and educators working to raise awareness of the climate crisis. Viewers gain insight into both the complexities of the climate system and the relentless curiosity that propels scientific discovery. The video concludes by highlighting urgent calls to action, emphasizing the interconnectedness of Earth’s systems and the necessity of continued engagement to address escalating global climate threats.
Dr. Peter Wadhams - is emeritus professor of Ocean Physics, and Head of the Polar Ocean Physics Group in the Department of Applied Mathematics and Theoretical Physics, University of Cambridge. He is best known for his work on sea ice.
Maria Pia Casarini - is a polar educator, explorer, and science communicator known for her leadership roles with the Society of Women Geographers and Polar Educators International.
