    • Modelling the Earth System - From Tipping Elements to Reconstructions 

      Bochow, Nils (Doctoral thesis; Doktorgradsavhandling, 2024-06-17)
      Climate change can trigger climate tipping points, which are among the major threats to human society. Tipping points are thresholds beyond which a system undergoes abrupt, often irreversible, changes even if the external forcing is brought to a halt. Several large-scale elements in the Earth system are considered tipping elements with global consequences once critical thresholds are crossed and ...
