Abstract
Scientific assessments play a critical role in synthesizing evidence to support evidence-based decision-making in many sectors and topics. For climate change, large-scale assessments like the Intergovernmental Panel on Climate Change (IPCC) and the United States (U.S.) National Climate Assessment (NCA) reports help many different users—from national government to local governments, Indigenous Peoples and communities, the private sector, the social sector, and the scientific community itself—navigate the complex field of climate risks, impacts, and integrated solutions. While co-creation with users is essential to developing actionable assessments, this paper lays the groundwork for future processes by identifying many advancing and emerging areas of relevant knowledge ready for assessment or additional near-term research. Drawing on the expertise of many scholars who were formerly tasked with producing the Sixth NCA and authors of other national or sub-national climate assessment reports, this paper highlights select U.S.-relevant topics in which research advances since the 2023 Fifth NCA make new syntheses particularly valuable for future national, sub-national, and sectoral climate assessments. It also identifies critical research topics in those select areas that would be useful for future climate assessment efforts. Overall, this research priorities roadmap aims to catalyze collaborations, research, and a network of climate assessments to synthesize the state of climate impacts, risks, and responses and to provide widely accessible and foundational information for sectoral, regional, and cross-cutting climate action plans and decisions in the U.S.

Abstract
Can socially or community-owned enterprise models systematically enable equitable climate action, as has been previously suggested by case study research? To empirically measure and test this proposition, we systematically surveyed all North American community land trusts (CLTs), which primarily serve lower-income households. We found that a majority of CLTs engage in climate action, with mitigation efforts more prevalent than adaptation efforts. Statistical analyses confirm CLTs’ rate of action cannot solely be explained by their climate hazards exposure. This suggests they can concurrently address economic precarity whilst enabling climate action, thereby enabling a “just transition”. Nonetheless, CLTs fail to engage in climate action as often as they would like, reflecting financial constraints shaped by policy choices. This suggests the simultaneous existence of a climate “double bind”, whereby CLTs must, to a degree, choose between economic security and climate goals. We conclude by identifying potential policies to address this double bind.

Matt is a designer and researcher hailing from the Great South Bay of Long Island, New York. He is an interdisciplinary PhD student, and University of Washington MLA Graduate, whose practice has ranged from helping to oversee the design and implementation of New York City’s green infrastructure program to shoreline design and permitting throughout the Pacific Northwest.
Matt’s research focuses on how ecosystem-based infrastructural adaptation strategies can serve as a mechanism for stemming the impacts of climate change, with a specific interest in the role that critical ecologies and keystone species can play in resilience/adaptation design and planning. His work investigates how traditional and emerging ecologically-based infrastructural techniques could be improved and more broadly applied, as well as how the resultant socio-ecological bonds formed by the implementation of these strategies may elevate the role of ecological systems thinking for design and planning practices within the built environment.
When not pondering relationality within the web of life Matt can be found paddling around the waters of Seattle with his shiba inu Hideki.

Abstract
Residential buildings play a significant role in global energy usage and carbon emissions. In Hong Kong, they contribute to 27% of energy usage and associated carbon emissions. Retrofitting residential buildings to net zero carbon (NZC) is an efficient way to lower carbon emissions and prevent climate change. However, the widespread adoption of NZC retrofitting in the industry has been limited by several challenges, which have rarely been addressed in research. This study intended to evaluate the linkages among various challenges while assessing their impacts on NZC retrofitting of existing residential buildings. Data were collected through a questionnaire survey with 123 residential building occupants in Hong Kong, whose perspectives are largely ignored in existing building retrofit research. Partial least squares structural equation modeling (PLS-SEM) was used to analyze the data. Outcomes indicated that technical and social challenges have a considerable negative effect on residential building NZC retrofitting. In addition, this study highlights the connections between challenge categories and presents a predictive model illustrating the relationships between challenges and residential building NZC retrofitting. Theoretically, the outcomes of this study provide new insights into the relationships between residential building NZC retrofitting challenges and their interactive effects, revealing that the challenges influence one another and do not exist in isolation. Practically, the findings could be useful to policymakers and practitioners seeking to promote NZC retrofitting by enabling the development of effective policies and strategies to mitigate the identified challenges.

Abstract
The lingering effects of redlining are linked to contemporary heat inequities observed across US cities. Residential security maps created by the Home Owners’ Loan Corporation (HOLC) have been widely used to analyze neighborhood-level disparities in land surface temperatures. However, the use of aggregated spatial units often fails to capture internal landscape heterogeneity and the heat vulnerabilities associated with redlining. In this study, we introduced urban landscape heterogeneity by incorporating granular development levels captured at different resolutions within HOLC-graded neighborhoods. This approach combined Landsat-based National Land Cover Database (NLCD) data, Sentinel-based WorldCover land cover data, and HOLC map layers. We examined the role of urban landscape heterogeneity in revealing additional patterns of heat inequities beyond those explained by redlining-based macro spatial units, using grouped boxplots and mixed-effects models across three major cities in the Northeastern US: Boston, Massachusetts; New York, New York; and Philadelphia, Pennsylvania. By accounting for urban landscape heterogeneity, our findings revealed that: (1) the well-documented trend of higher land surface temperatures in lower HOLC grades becomes systematically fragmented, (2) statistical models show improved performance in estimating land surface temperature, and (3) the cooling effect of tree canopy exhibits a varying, non-linear threshold pattern. These results highlight the need to consider micro-scale landscape dimensions to better understand the persistent, unequal distribution of temperatures associated with redlining. Municipal and community-led tree planting initiatives should consider comprehensive landscape characteristics to develop spatially targeted heat mitigation strategies and promote equitable climate outcomes.

Abstract
Climate adaptation is imperative; however, instances of maladaptation are increasingly documented in sectors and locations around the world. Despite the prevalence of maladaptation, researchers and intergovernmental actors, including the Intergovernmental Panel on Climate Change, consistently frame it as “unintentional.” Drawing from environmental injustice, critical development studies, critical race theory, and coloniality scholarship, we argue the impossibility of characterizing maladaptation—now a global-scale phenomenon—as an unintended consequence of well-intentioned adaptation planning. This paper reframes the (re)production of climate maladaptation as a foreseeable result of the unequal systems of colonial racial capitalism through which adaptation is implemented and refracted. Systems-level change that confronts uneven relations of power, rather than incremental institutional reform, can address the prevalence of maladaptation. Treated as such, tackling climate maladaptation becomes a “political project”— not merely a “planning project.”

Abstract
Urban greenspace (UGS) is a crucial nature-based solution for mitigating increasing human exposure to extreme heat, but its long-term potential has been poorly quantified. We used high spatial-temporal resolution data sets of urban land cover and population grid in combination with an urban climate model, machine learning, and land use simulation model to assess the impact of UGS on population exposure to extreme (high-heat exposure, HHE) and its potential spatial optimization strategies. Results showed that the UGS and HHE have a strong spatiotemporal dynamic coupling in 21st century Chinese cities. Moreover, UGS shrinkage increased the HHE by 0.58–1.15 °C, while UGS expansion mitigated it by 0.72–1.26 °C, both stronger in the SSP3–7.0 and SSP5–8.5 scenarios. Different from common impressions, spatial relationships, rather than quantities of UGS, are more influential (1.3–1.8 times) on HHE. Our solutions suggest that simply enhancing the spatial dynamic connectivity between patches can mitigate HHE by 9.1–21.1%, especially for the eastern and central cities. Our results provide an example of how to improve climate adaptation in urban ecological space designs and strongly promote research on optimal spatial patterns for future robust urban heat mitigation.
