A draft version of the Fifth National Climate Assessment (NCA5) is now available for a 12-week public review and comment period. Additional information on this request can be found in the Federal Register Notice.

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 and user guide .

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 reviews 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. Please note that this is a draft document and it should not be cited, quoted, or distributed for purposes beyond this review.
