Jennie first investigated the biological effects of global change in 1992, when she joined a project looking at the effects of ozone depletion on Antarctic sea urchin embryos. She has since expanded her work to include interactive effects of warming and ultraviolet radiation on marine organisms, climate change vulnerability assessment, and adapting conservation and natural resource management to a changing climate. In addition to her peer-reviewed scientific papers, Dr. Hoffman is author or co-author of several books and reports, including Climate: The Force That Shapes Our World and the Future of Life on Earth, and Buying Time: A User's Manual for Building Resistance and Resilience to Climate Change in Natural Systems. The User’s Manual lead to the development of Climate Camp workshops, a participant-driven process to help resource managers, conservation practitioners, and others create strategies to reduce the vulnerability of their work to climate change. Jennie has helped lead multiple Climate Camps for participants from around the globe. She earned her Ph.D. at the University of Washington in Ecology and her undergraduate degree in geology and biology from Brown University. After five years of working with the WWF-International Climate Change Programme’s Impacts and Adaptation group as a consultant and employee, Jennie joined with Lara Hansen and Eric Mielbrecht to start a new non-profit, EcoAdapt, focused on climate change adaptation.
