Steep rock faces, surrounded by vast glaciers and massive icebergs floating far below on the ocean - Greenland's nature is truly unique. Not only in terms of the landscape but also because Greenland’s glaciers and ice caps play a crucial role in climate change. However, exploring their condition can be extremely difficult as they are almost inaccessible due to their remote location.

Our two guests in this episode faced this challenge. French glaciologist Dr. Heïdi Sevestre researched the effects of climate change in remote regions of Greenland, supported by a team of scientists and three of the world's best climbers.

One of these climbers is Alex Honnold. He gained worldwide fame through the Oscar-winning documentary "Free Solo," which is about his free solo climb of El Capitan in California's Yosemite National Park. His goal in Greenland was to make the first ascent of one of the highest unclimbed rock walls of the world while also contributing to science. Thus, he embarked on a memorable expedition with Heïdi and a team of climbers and local experts. The expedition was documented in the three-part series "Arctic Ascent with Alex Honnold" by National Geographic.

In this episode, Alex and Heïdi give us insights into the challenges of a first ascent in Greenland’s rugged nature, the on-site research work, and the impact of climate change on a wilderness which is crucial for the future of the planet.
