Scope 
Understanding the mechanisms and variability of the Earth climate system across different timescales is essential for sustaining the biosphere and human society. Anthropogenic forcing has increasingly modified the climate system through physical and chemical perturbations, affecting ecosystems and human activities on a global scale. This session invites contributions on Quaternary and Anthropocene climate change derived from natural archives, proxy data, and modeling approaches. We particularly encourage studies addressing hydrological and atmospheric variability, extreme climatic events, and the coupled interactions among the atmosphere, ocean, and greenhouse gases that drive global climate change.
