Volume II of the Fourth National Climate Assessment (NCA4), Impacts, Risks, and Adaptation in the United States, analyzes the impacts of global change, as described in Volume I (Climate Science Special Report), on topics and regions of the United States.
The development of NCA4 Vol. II was overseen by a Federal Steering Committee appointed by the SGCR and comprising representatives from USGCRP agencies. NOAA, as the administrative agency for NCA4, was responsible for establishing procedures for the report, releasing Federal Register Notices, and certifying the report met Information Quality Act standards. It has undergone an extensive, multi-phase process of internal and external review from Federal agency experts, the general public, and a panel of experts from the National Academies of Sciences, Engineering, and Medicine.
The following groups contributed to NCA4 Vol. II:
- A Federal Steering Committee (SC) was responsible for the development, production, and content of the report as well as high-level scoping to ensure coherence, relevance, and responsiveness to the Global Change Research Act and the USGCRP Strategic Plan. The SC selected Federal Coordinating Lead Authors, Regional Chapter Leads, and Review Editors based on a number of criteria, including scientific expertise and experience with scientific assessments.
- Federal Coordinating Lead Authors (CLAs) oversaw development of a given chapter and liaised with non-Federal Regional Chapter Leads or Federal or non-Federal National Chapter Leads in their development of individual chapters. The Federal CLAs also worked across chapters to ensure consistency throughout the report.
- Agency Chapter Leads oversaw the production of the National Topic and Response chapters and select National Chapter Leads. Effort was made to distribute the responsibility across USGCRP agencies.
- National Chapter Leads were either Federal or non-Federal experts who, in consultation with Federal CLAs, organized, directed, and led authorship of individual National Topic or Response chapters. Chapter Author teams were established by the National Chapter Leads, with suggestions from the Federal CLAs and the SC. Chapters were submitted to the corresponding Federal CLA, and ultimately transmitted to the SC as the individual input of the National Chapter Leads.
- Regional Chapter Leads were non-Federal experts selected by the SC from a pool of experts put forward through a public nominations process. In consultation with Federal CLAs, Regional Chapter Leads organized, directed, and led authorship of individual regional chapters. Chapter Author teams were established by the Regional Chapter Leads, with suggestions from the Federal CLAs and the SC. Chapters were submitted to the corresponding Federal CLA, and ultimately transmitted to the SC as the individual input of the Regional Chapter Leads.
- Chapter Authors were selected by the Chapter Lead and responsible for developing chapter content. Chapter author teams worked with Regional or National Chapter Leads to develop and edit individual chapters in response to comments received during the multiple rounds of review.
- Technical Contributors provided inputs into chapter development, but did not directly author sections of NCA4 Vol. II. They were selected on an as-needed basis, based on specific needs identified by the author team.
- Review Editors were selected by the SC from a pool of experts put forward through a public nominations process. Their role was to ensure the authors adequately responded to all comments received during the public and National Academies review periods.
