Erika Spanger-Siegfried, the Director of Strategic Climate Analytics in the Climate and Energy program at the Union of Concerned Scientists, researches, writes and speaks about U.S. climate change impacts and preparedness. She currently manages UCS’s climate impacts analyses, work that helps shed light through new research, analysis and outreach on ongoing climate change impacts, current efforts to cope with these impacts, and the urgency of strong leadership and action.
Most recently, Ms. Spanger-Siegfried has overseen and co-authored UCS’s leading-edge work around coastal flooding and extreme heat, including "When Rising Seas Hit Home" and "Killer Heat in the United States"
Ms. Spanger-Siegfried formerly managed several multi-year climate research and engagement projects. These included the Energy-Water Initiative, aimed at raising awareness of the connection between energy use and water consumption, particularly in the context of climate change; and the Northeast Climate Impacts Assessment, a collaboration between UCS and a multi-disciplinary team of more than 50 scientists from across the region that explored future climate change in Northeast states and impacts on key sectors.
Prior to joining UCS in 2005, Ms. Spanger-Siegfried was an associate scientist at the U.S. Center of the Stockholm Environment Institute, where for six years her work focused on understanding and building the adaptive capacity of vulnerable populations and sectors in developing countries in response to climate change. Earlier in her career, Ms. Spanger-Siegfried worked with the Harvard Center for Health and the Global Environment and the Massachusetts Department of Public Health's environmental laboratories. She has served on several relevant advisory bodies, including the Massachusetts' Climate Change Adaptation Advisory Committee.
Ms. Spanger-Siegfried has an M.S. in energy and environmental analysis from Boston University and a B.S. in fisheries biology from the University of Massachusetts Amherst.
Ms. Spanger-Siegfried has been quoted widely, including by The Boston Globe, Chicago Tribune, Christian Science Monitor, CNN, The Miami Herald, USA Today, The Washington Post, and Yahoo! News, and has appeared on CBS News Radio and numerous local commercial and public radio news stations.
