David Lea

David Lea is a Professor in the Department of Earth Science at the University of California, Santa Barbara. His research focuses on understanding Earth's climate system through geological records, with particular emphasis on oceanography, paleoceanography, and their implications for modern climate change. He has contributed to studies of marine proxies (e.g., foraminiferal Mg/Ca, Na/Ca), ocean circulation dynamics, and glacial-interglacial climate transitions. His work integrates field-based data from sediment cores and fossil records with advanced modeling techniques to explore long-term climate variability and human impacts on the environment.

Lea’s research spans a wide temporal scale, from recent Holocene climate variability to glacial cycles and Pliocene-Pleistocene transitions. He has investigated tropical Pacific climate dynamics, Indo-Pacific Warm Pool evolution, and the role of ocean heat content in moisture transport. His recent projects address low-carbon transition pathways and environmental equity in California’s energy sector. Lea is affiliated with the Earth Research Institute and collaborates with interdisciplinary teams on global change research.

Key contributions include refining paleotemperature proxies and analyzing climate teleconnections. His studies on carbonate dissolution and sedimentary records from the Eastern Equatorial Pacific have advanced understanding of equatorial climate processes.
