Deb Campbell, a senior staff member in the HADR Systems Group, started the session with a discussion of how to accelerate the national and global response to climate change. "Because the timeline is so short and challenges so complex, it is essential to make good, evidence-based decisions on how to get to where we need to go," she said. "We call this approach systems analysis and architecture, and by taking this approach we can create a national climate change resilience roadmap." This roadmap implements more of what we already know how to do, for example utilizing wind and solar energy, and identifies gaps where research and development are needed to reach specific goals. One example is the transition to a fully zero-emission vehicle (ZEV) fleet in the United States in the coming decades; California has already directed that all of the state's new car sales be ZEV by 2035.
