Modeling the Impact of Storm Surge Flooding and Associated Costs on North Carolina Coastal Region Corn and Soybean Fields via Remote Sensing
Published: 2024-06-16
Subjects: Earth Sciences, Environmental Sciences, Physical Sciences and Mathematics
Hurricane and tropical storm-driven storm surge flooding places coastal farmlands at high risk of crop damage and soil salinization. The damage can total to millions of dollars in costs and force farmers to abandon coastal fields. Additionally, many agricultural, and often rural, areas are unable to access accurate and reliable flood-risk projection maps and analyses that can inform prevention [...]

Evaluating estimation methods for wildfire smoke and their implications for assessing health effects
Published: 2024-06-13
Subjects: Environmental Health and Protection, Environmental Public Health, Environmental Sciences, Public Health
Growing wildfire smoke represents a substantial threat to air quality and human health in the US and across much of the globe. However, the impact of wildfire smoke on human health remains imprecisely understood, due to uncertainties in both the measurement of population wildfire smoke exposure and dose-response functions linking exposure to health. Here, we compare daily wildfire smoke-related [...]

Coastal settlements, facing increasing flood risk from Tropical Cyclones (TCs) under climate change, need local and detailed climate information for effective adaptation. Analysis of historical events and their impacts provides such information. This study uses storylines to evaluate adaptation strategies, focusing on Cyclone Idai’s impact on Beira, Mozambique, under different climate [...]
Mitigating marine plastic debris in Hong Kong: an action plan
Published: 2024-05-31
Subjects: Environmental Sciences, Other Environmental Sciences, Other Physical Sciences and Mathematics
The impact of marine debris ranges from ecological and social to economic, including ingestion by wildlife, loss of tourist potential and high costs of clean-ups and reallocation of collected litter. In Hong Kong, an astounding amount of litter is collected annually, encompassing plastic food packaging, bottles and bottle caps. With over 60% of discarded items originating from shoreline [...]
Opening doors to physical sample tracking and attribution in Earth and environmental sciences
Published: 2024-05-31
Subjects: Biochemistry, Biophysics, and Structural Biology, Earth Sciences, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Microbiology, Physical Sciences and Mathematics, Systems Biology
Physical samples and their associated (meta)data underpin scientific discoveries across disciplines and can enable new science when appropriately archived. However, there are significant gaps in current practices and infrastructure that prevent accurate provenance tracking, reproducibility, and attribution. For most samples, descriptive metadata are often sparse, inaccessible, or absent. Samples [...]
Spatial Patterns of Urban Heat Islands and Green Space Cooling Effects in the Urban Microclimate of Karachi

Subjects: Climate, Environmental Sciences, Forest Sciences, Physical Sciences and Mathematics, Sustainability
With rapid urbanization and the increasing threats of climate change, metropolitan cities like Karachi, Pakistan, are encountering greater challenges due to the Urban Heat Island (UHI) phenomenon. Understanding the cooling potential of urban green spaces (UGS) is crucial for mitigating heat stress and enhancing urban resilience. This study aims to analyze the thermal dynamics and cooling efficacy [...]
Mercury records from natural archives reveal ecosystem responses to changing atmospheric deposition
Published: 2024-05-15
Subjects: Atmospheric Sciences, Environmental Sciences, Geochemistry, Geography, Physical and Environmental Geography
Global ecosystems face mercury contamination, yet long-term data is scarce, hindering understanding of ecosystem responses to atmospheric Hg input changes. To bridge data gap and assess ecosystem responses, we compiled and compared a mercury accumulation database from peat, lake, ice, and marine deposits worldwide with atmospheric mercury deposition modeled by GEOS-Chem, focusing on trends, [...]
Misconceptions in the application of the Arrhenius equation to plastics - environmental degradation of plastics unlikely below their glass transition temperature
Published: 2024-05-10
Subjects: Earth Sciences, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
The term ‘’plastic’’ is derived from the Greek word ''plastikos'', meaning fit for moulding, highlighting the main feature that makes plastics so useful, i.e., their malleability during manufacture, allowing plastics to be formed into a variety of shapes such as bottles, bags and straws1. However, this malleability is temperature-dependent requiring the constituent polymers to be in the molten [...]
