We invite abstract submissions to our AGU session **PP004. Advancing Paleoclimatology by Combining Data, Models, and Theory**. Presenters from all backgrounds and career stages are welcome. The submission deadline is 31 July 2025 (23:59 EDT/03:59 +1 GMT).

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.
