Urban Trees and Cooling: A Review of the Recent Literature (2018 to 2024) Open
Urban trees mitigate extreme heat through shading and evapotranspiration, but cooling effectiveness varies with tree traits, spatial configurations, and climate. This systematic mapping review synthesizes findings from 115 studies (2018 to…

Perceptions and physical drivers of extreme heat at transit stops Open
Extreme urban weather generates unequal impacts on human health and well-being, with transit stops often serving as critical points of exposure to extreme micro-climatic conditions. These locations are essential for urban mobility, particu…

A nationwide evaluation of crowd-sourced ambient temperature data Open
Growing concerns about heat in urban areas paired with the sparsity of weather stations have resulted in individuals drawing on data from citizen science sensor networks to fill in data gaps. In the past decade, a proliferation of crowd-so…

Land-use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city Open
Home Owners’ Loan Corporation (HOLC) maps illustrated patterns of segregation in United States cites in the 1930s. As the causes and drivers of demographic and land-use segregation vary over years, these maps provide an important spatial l…

Sequoia Groves of Yosemite: Visitor Use and Impact Monitoring Open
Despite being long-lived and massive, giant sequoias (Sequoiadendron giganteum (Lindl.) J. Bucholz) are susceptible to erosion given their relatively shallow root structure. Human-caused soil compaction and vegetation loss through social t…

Intra-urban variations in land surface phenology in a semi-arid environment Open
Urban vegetation is growing in importance as cities use ‘green infrastructure’ to mitigate the impacts of climate change, reduce extreme heat, and improve human health and comfort. However, due to the heterogeneity of city landscapes, urba…
View article: Urban tree cover provides consistent mitigation of extreme heat in arid but not humid cities
Urban tree cover provides consistent mitigation of extreme heat in arid but not humid cities Open
Urban land cover types influence the urban microclimates. However, recent work indicates the magnitude of land cover's microclimate influence is affected by aridity. Moreover, this variation in cooling and warming potentials of urban land …

Role of Vegetation in mitigating urban heat risk in Twelve American Cities - Applying the ARIES Modelling Approach Open
The anthropogenic urban realm exacerbates surface urban heat island (UHI) effects, triggering health hazards, such as mortality attributable to heat exposure in cities. The study makes a concerted effort to unravel the complex interplay be…
View article: Limited Role of Absolute Humidity in Intraurban Heat Variability
Limited Role of Absolute Humidity in Intraurban Heat Variability Open
Monitoring and understanding the variability of heat within cities is important for urban planning and public health, and the number of studies measuring intraurban temperature variability is growing. Recognizing that the physiological eff…

Irrigated urban trees exhibit greater functional trait plasticity compared to natural stands Open
Urbanization creates novel ecosystems comprised of species assemblages and environments with no natural analogue. Moreover, irrigation can alter plant function compared to non-irrigated systems. However, the capacity of irrigation to alter…

Urban landcover differentially drives day and nighttime air temperature across a semi-arid city Open
Semi-arid urban environments are undergoing an increase in both average air temperatures and in the frequency and intensity of extreme heat events. Within cities, different composition and densities of urban landcovers (ULC) influence loca…
View article: Greater aridity increases the magnitude of urban nighttime vegetation-derived air cooling
Greater aridity increases the magnitude of urban nighttime vegetation-derived air cooling Open
High nighttime urban air temperatures increase health risks and economic vulnerability of people globally. While recent studies have highlighted nighttime heat mitigation effects of urban vegetation, the magnitude and variability of vegeta…
