Evan Girvetz is a senior scientist with The Nature Conservancy’s Global Climate Change Program. He provides expert support on climate change impacts and ecosystem-based adaptation to Conservancy programs and project teams. He also co-leads the development of the Climate Wizard, an online tool that allows non-climate specialists to explore climate change maps and analyses.
Evan is a conservation ecologist with extensive experience in conservation planning, environmental decision support, and climate change impact assessment. He is widely published and his research has been featured in top media outlets including the San Francisco Chronicle, Seattle Times and New Scientist magazine. Evan received his Ph.D. in Ecology from the University of California, Davis, and currently holds an affiliate assistant professor position at the University of Washington, School of Forest Resources.
