Abstract Comprehensive assessments of scientific knowledge are essential to inform efforts to mitigate greenhouse gas emissions and adapt to climate change impacts. The Fifth National Climate Assessment (NCA5), released in late 2023, adopted clear diversity, equity, accessibility, and inclusion (DEAI) goals and trainings, which helped diversify expert participation, broaden the types of knowledge included, and widen public engagement. This Letter, written by NCA5 authors, reflects on the impacts and limitations of these efforts and suggests specific actions to further promote collaboration, honor and recognize the knowledge of frontline communities, and guide more just and holistic climate assessments.
