Nico on being climate change's eyewitness

When Nico Hojac was 15 years old, he went on a language exchange to Val Ferret. But instead of learning French, he discovered his passion for the mountains. As we traverse the Konkordiaplatz glacier roped together, Nico guides us with ease; his experience, knowledge and devotion to the mountains obvious. Resting at a safe point on our route, Nico tells us how his sport and profession are at risk from climate change.
