However, with the availability of various gridded climatic data sets, a critical question is whether spatially explicit data can better capture individual environmental exposures and reveal stronger climate-health associations. We investigated the impact of spatial-scale climatic variability and representativeness for emergency department (ED) visits in Richmond, Virginia, United States. This study compared the climate-health relationship using data from a weather station and the ERA5 reanalysis from 2016 to 2022. We evaluated the correlation of the two time-series and used generalized additive models to compare the temperature-ED visit associations across four nested spatial scales. The results were highly consistent across all spatial scales. The station and ERA5 data exhibited similar distributions. The temperature-ED visit relationships showed strong agreement between the two data sources, reflected in both location-specific and pooled estimates. Although ERA5 produced slightly lower cold-related and higher heat-related estimates at extreme temperatures, no marked differences were found between the two data sources. Our findings suggest that, in this region with a relatively homogeneous climate, the variations of regional climate might be small enough to fall within the model's expected uncertainty. Although this result may not apply in regions with considerable local climate variation, data from a single high-quality station in many regions are appropriate to model climate-health relationships over the greater surrounding areas. We recommend similar comparative work across diverse climatic settings to evaluate the generalizability of this conclusion.</p>","PeriodicalId":48618,"journal":{"name":"Geohealth","volume":"10 9","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13555616/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148921436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research employed a mixed-method approach to investigate EJ research trends and roadblocks to engagement. Study 1 used a bibliometric analysis of Scopus-indexed publications and found that Environmental science and Social sciences were the leading contributors to EJ scholarship.

Study 2 investigated this discrepancy through a survey of Earth scientists (<i>N</i> = 460) examining perceived barriers to EJ engagement. Results indicated that career stage was a significant predictor of EJ familiarity and community involvement: early-career Earth scientists were more familiar with EJ but were less involved in their communities' environmental issues than their late-career counterparts. Race and ethnicity were also associated with differences in perceived funding difficulty, with White respondents reporting fewer challenges in securing support for EJ-related projects. Taken together, these studies assess EJ engagement within the Earth sciences and identify structural and experiential factors that may limit participation.

Meningococcal meningitis incidence is highly seasonal in this region specifically, with outbreaks mostly occurring during the dry season, characterized by low rainfall and atmospheric humidity, high temperature, and increased dust and wind speed. The strong seasonality of meningococcal outbreaks coincides with seasonal variation in climatic factors. This multicollinearity can make it difficult to identify environmental drivers of disease and the mechanisms by which they operate. This review aims to collate existing evidence to better clarify the mechanisms by which climatic variables influence meningococcal meningitis incidence. We examined the impact of dust, wind speed, temperature, rainfall, and land cover on meningococcal meningitis outbreaks. Within the literature, atmospheric dust and wind speed had the strongest statistical association with meningococcal outbreaks and demonstrated greater predictive probability than other climatic variables. However, several climatic factors have demonstrable influences on one another, reflected in the seasonality of meningococcal meningitis. Atmospheric dust can reduce precipitation levels in part through its radiative properties. Decreased rainfall and increasing temperatures can dry out soil, increasing its availability to be uplifted as dust. Alongside, this lower atmospheric humidity increases evaporative demand, leading to faster soil moisture loss and enhanced surface drying. We argue that rainfall, temperature, and land cover variability may act as part of a broader climatic mechanism, increasing atmospheric dust. This increases the incidence and risk of meningococcal meningitis.</p>","PeriodicalId":48618,"journal":{"name":"Geohealth","volume":"10 9","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2025GH001749","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148849373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It deeply explored the complex temporal relationships and spatial differences between environmental driving factors and the HRRD (hospitalization rate of respiratory diseases). It quantified the nonlinear relationships and lag effects of environmental driving factors on the HRRD. Additionally, it conducted a quantitative analysis of the specific impacts of each factor on the hospitalization rate under different spatio-temporal conditions. The research results show that there are significant differences in the lag effects of extreme meteorological factors, air pollutants, and comprehensive meteorological factors on respiratory diseases among different age groups. Similarly, the impacts of these factors on the HRRD also exhibit different spatial heterogeneities.

This study addresses these gaps by quantifying moderate and extreme heat-attributable mortality across 28 thermoclimatic areas (TAs)—a climatic subdivision of the Valencian Region— from 1975 to 2019, using a two-stage time-series analysis of high-resolution temperature and mortality data. Results reveal a distinct coastal–inland gradient, with significantly higher mortality impacts in inland TAs compared to coastal provincial capitals. Areas most impacted by extreme heat are concentrated in interior regions, while coastal capitals exhibit lower risks. These findings underscore the limitations of relying on administrative boundaries for public health surveillance and adaptation planning. The study highlights the value of climatically coherent zones, such as TAs, for improving the spatial resolution of early warning systems and tailoring heat prevention strategies.
