Mesozoic & Early Cenozoic Greenhouse Climates: Extreme Analogs for Future Global Change

Session ID#: 81506

Session Description:
Anthropogenic activities have driven the concentration of atmospheric carbon dioxide above 410 ppm. As pCO2 continues on this trajectory, deep-time paleoclimate work will become more relevant to near future climate. The greenhouse climates of the Mesozoic and Paleogene represent end-member analogs for a future warm Earth. Understanding changes and interactions between the climate, ocean, and biosphere during these intervals is important for contextualizing the consequences of anthropogenic climate change. We invite abstracts that present stratigraphic, geochemical, ecological, and paleoceanographic records of greenhouse climates, including temperature reconstruction, water column structure, ocean circulation, weathering, sea-level rise, oceanic anoxic events, hyperthermals and other carbon cycle perturbations, and ecological change and evolutionary turnover across marine and terrestrial depositional environments. Because the societal relevance of such deep-time work is currently undervalued, we encourage authors to highlight how their findings about past warm climate can be used to inform what may happen in the future.
