Yet the processes that deliver CDW to the ice sheet remain uncertain. Traditional climate models lack the res olution to capture the dynamics necessary to resolve the processes leading to CDW delivery to ice shelves. In this presentation\, I will explore how novel global high-resolution climate simulations offer new insights into the drivers of CDW dynamics\, while also posing significant computational challenges.\n\n Biography: Mira Berdahl is a Research Scientist at the U niversity of Washington whose work focuses on cryosphere–climate interac tions. She combines climate and ice sheet modeling with in situ observatio ns to understand how glaciers and ice sheets respond to climate change.\n\ n"Exploring the relationship between land access and perceived adaptive ca pacity to climate change among organic farmers in the United States: A Bay esian modeling approach"\n\nAbstract: As seasons become less predictable a nd extreme weather events become more frequent and intense\, farmers learn to adapt. This challenge is no less for organic farmers\, who make import ant contributions to social well-being and ecological regeneration through their food production practices. Thus\, it is vital to understand the con straints that affect the extent to which organic farmers can engage in cli mate adaptive practices. This research uses Bayesian structural equation m odeling to assess the relationship between land access and perceived adapt ive capacity to climate change among certified organic farmers in the Unit ed States. Survey data collected by the Organic Farming Research Foundatio n are integrated with meteorological data measuring drought\, temperature extremes\, and climatic variability. Perceived ability to adapt to climate change is used as the outcome variable to reflect the cognitive dimension s of adaptation decision-making. A latent variable is created that represe nts both current land access and future land needs. The model results sugg est that at the population level\, increased land access and land needs ha ve a moderately negative\, albeit uncertain\, association with challenges adapting to climate change. Precipitation variability\, relative heat extr emes\, challenges accessing financial capital\, and increasing number of s ales channels are positively associated with challenges adapting to climat e change with more certainty\, while increased sales through wholesale cha nnels has a more certain\, negative association. This research more broadl y signals how Bayesian approaches offer a promising way to integrate quali tative findings into quantitative analyses\, while accounting for uncertai nty inherent in complex socio-ecological systems.\n\n\n Biography: Masha is a graduate student at the University of Washington’s School of Envir onmental and Forest Sciences. She studies the factors that influence how f armers are adapting to climate change and is especially interested in the role of seed diversity in climate resilience. She employs qualitative and quantitative methods that include conducting interviews\, evaluating surve y data\, and analyzing satellite imagery. Her learning extends beyond the classroom and into the field as an avid gardener and part-time farmworker. Before graduate school\, she was a communications professional at a legal advocacy organization focused on building a more just food system. \n\n\n \n\nThe 2025-2026 seminars will be held in person\, and are free and open to the public.
