The New York City Panel on Climate Change (NPCC) is a panel of experts to advise on issues related to climate change and adaptation that consists of over 40 public- and private-sector stakeholders. The NPCC has assisted the New York City Climate Change Adaptation Task Force, which was established by the City to develop a coordinated adaptation plan for the city. The NPCC has prepared a set of climate change projections for the New York City region and has examined how climate change has the potential to both positively and negatively affect the critical infrastructure of New York City. It has suggested approaches to create an effective adaptation program for critical infrastructure, including ways to assess risks, prioritize strategies, and examine how standards and regulations may need to be adjusted in a changing climate. To carry out these tasks, the NPCC prepared this report to lay the foundation for climate change adaptation in the city and created three workbooks to guide Task Force members in their climate change adaptation planning process: The Climate Risk Information (CRI) workbook presents climate trends and projections for New York City and identifies potential risks to the city's critical infrastructure posed by climate change (Appendix A). The Adaptation Assessment Guidebook (AAG) outlines a process through which stakeholders can develop and implement adaptation plans (Appendix B). The Climate Protection Levels (CPL) workbook evaluates some of the policies, rules, and regulations that govern infrastructure in New York City to determine how they could be affected by climate change (Appendix C).
