“Acceptance Speech” Frontiers of Knowledge Award 2023 in Climate Change

Acceptance speech by Jakob Schwander, winner of the 2023 Frontiers of Knowledge Award in Climate Change, who was honored alongside Dorthe Dahl-Jensen, Jean Jouzel, Valérie Masson-Delmotte and Thomas F. Stocker for demonstrating the relationship between greenhouse gases and atmospheric temperatures over the past 800,000 years. His innovations in ice core drilling and analysis techniques have contributed to more accurate reconstructions of past climates.

Schwander’s research has made it possible to obtain more precise records of atmospheric composition and climate variations from air bubbles trapped in polar ice. His contributions include the development of new drilling technologies, such as the RADIX system, which facilitates access to deep ice layers under extreme conditions. These advances highlight the importance of technological innovation and international collaboration in understanding climate evolution and the effects of global warming.
