On Thin Ice: Glaciers, Geopolitics, and Nature's Goods

BBC Radio 4 - Start the Week, On Thin Ice: Glaciers, Geopolitics, and Nature's Goods

Kirsty Wark with Jemma Wadham, Anne Sverdrup-Thygeson and Dwayne Ryan Menezes.

Jemma Wadham, Anne Sverdrup-Thygeson and Dwayne Ryan Menezes explore the polar regions – from glaciers to rare earth metals with Kirsty Wark.

Once-indomitable glaciers – from high up in the Himalayas to the polar regions – are today in grave peril, as our climate warms at an accelerating rate. The glaciologist Jemma Wadham says that melting ice sheets not only leads to meltwater overwhelming sensitive marine ecosystems but could also release vast quantities of methane. In her book Ice Rivers she shows that far from being freezing sterile environments, the world’s glaciers are teeming with microbial life, as rich and fascinating as the forests. 

Record ice loss last year and the effect of climate change are also having an impact on geopolitics and international relations. Dwayne Ryan Menezes, the founding director of the think tank Polar Research and Policy Initiative looks at the viability of a busy sea route through the arctic region as ice recedes for longer periods. And he explains why the recent elections in Greenland – a territory of just over 56,000 people – sent reverberations around the world. 

The importance of nature’s finely-tuned system to our everyday lives is at the heart of Anne Sverdrup-Thygeson’s research at the Norwegian University of Life Sciences. In her new book Tapestries of Life she uncovers many of the lifesaving secrets of the natural world which impact directly on humans, from medicines to pollution control, carbon sequestration to spiritual health.
