Session Proposal: Advancing Paleoclimatology by Combining Data, Models, and Theory (AGU25)

PP004
Advancing Paleoclimatology by Combining Data, Models, and Theory

Session ID#: 247502

Session Description:
Our most powerful constraints on past climate are developed through combining observational data with models and theory. This intersection allows us to test hypotheses, refine model physics,  develop data-informed state estimates of past climates, and ultimately advance the theoretical principles underpinning our dynamical understanding of the climate system. We highlight a range of tools and methodologies, including: advancements in linking environmental variables to paleoclimate proxies; the design and implementation of proxy system models; innovative approaches for integrating numerical models with data (such as data assimilation and machine learning techniques); and the use of model hierarchies, from idealized physical models to comprehensive climate models.We welcome submissions that apply these tools to key paleoclimate questions, including but not limited to: characterizing climate variability (including climate extremes), reconstructing past ecosystems and climates, understanding specific dynamical processes across space and time, and leveraging paleoclimate insights to improve future climate projections.
