Focus: Understanding past climate variability to enhance future climate-change projections

 

The climate history since the Last Interglacial (~130,000 years ago) is marked by profound transitions, ranging from abrupt events to gradual reorganizations of the Earth system. This period offers a unique testing ground for evaluating and refining Earth system models across a wide spectrum of boundary conditions, from glacial extremes to interglacial warmth.

 

Simulating the climate dynamics of the last glacial cycle - including transitions, feedbacks, and tipping elements - enables us to assess the structural robustness of Earth system models used for future projections. Such model – data comparisons are critical not only to constrain uncertainties, but also to understand possible regime shifts in climate variability, the emergence of nonlinear behavior, and the relevance of long-term feedbacks under anthropogenic forcing.
