Public Comment Period Open for 5th National Climate Assessment

The U.S. Global Change Research Program is pleased to announce that a draft version of the Fifth National Climate Assessment (NCA5) is now available for a 12-week public review and comment period.

Reviews are a vital part of the NCA5 development process. In addition to this public comment period, NCA5 is being reviewed by a committee of the National Academies of Sciences, Engineering, and Medicine. All of the feedback received through these processes will be considered by the chapter authors for future drafts of the assessment. The final version of NCA5 is expected to be released in late 2023.

This review is free and open to everyone. People who wish to review and comment on the draft report can do so via the USGCRP Review and Comment System (registration required). Instructions for comment submission are available on that site and in this brief recording. Please note that this is a draft document and it should not be cited, quoted, or distributed for purposes beyond this review. 

Additional information can be found in the Federal Register Notice and in this USGCRP Open Notice.

All comments must be submitted by 11:59 PM ET on January 27, 2023 via the USGCRP Review and Comment System

Informational Webinars

USGCRP is hosting two free webinars for people interested in learning more about NCA5, the importance of public participation, and how to submit comments on the draft report. No registration is required.
