Fifth National Climate Assessment - Read the Report

Updates on NCA5

January 25th, 2021
NASA, on behalf of USGCRP, issued a Federal Register Notice (FRN) seeking author nominations and scientific/technical inputs for the Fifth National Climate Assessment (NCA5). The FRN, which opened October 15, 2020 and closed the following month on November 14, also served as a notice of planned public engagement opportunities.
Prospective authors nominated through this call may be invited to serve as Chapter Lead Authors, Authors, or Technical Contributors to NCA5. The chapter topic lists in this solicitation were shaped by the responses from an FRN issued in July—a request for comment on the NCA5 Draft Prospectus
We invite you to share additional information or technical inputs (peer-reviewed literature, gray literature, case studies, etc.) with the chapter author teams here.
