Subjects: Climate, Environmental Indicators and Impact Assessment, Environmental Studies, Sustainability

The aviation sector faces a significant challenge in mitigating climate change due to the dual impact of CO2 emissions and contrail formation. Contrails, which form under specific atmospheric conditions, contribute to global warming. Mitigating contrails, however, can require flight path diversions, leading to increased fuel consumption and CO2 emissions. This study evaluates various climate [...]

Foreign direct investment (FDI) can reshape landscapes in developing countries, but its impact remains unclear. This study examines how China’s Belt and Road Initiative (BRI) FDI impacts land-cover and land-use change in Southeast Asia, a key trade partner receiving significant Chinese infrastructure investments. Focusing on areas with BRI investments from 2008 to 2018, we utilize satellite data [...]

Globally, droughts are becoming longer, more frequent and more severe, and their impacts are multidimensional. The impacts of droughts typically extend beyond the water balance as they accumulate over time, and can lead to regime shifts in land use. Here, we assess the effects of temporal changes in water supply and demand on vegetation productivity and land cover change over multiple time scales [...]

Subjects: Climate, Environmental Indicators and Impact Assessment, Oil, Gas, and Energy

Exports of liquefied natural gas (LNG) from the United States are growing rapidly, and the United States government must balance a multiplicity of interests in deciding to what extent the growth of LNG exports should be further encouraged. Its decisions must be consistent with the Natural Gas Act, which mandates that exports of natural gas be in the public interest. In the current administration, [...]

Navigating and attributing uncertainty of future tropical cyclone risk estimates

Simona Meiler, Chahan M. Kropf, Jamie W. McCaughey, et al.

Published: 2024-03-22
Subjects: Climate, Environmental Indicators and Impact Assessment

Future tropical cyclone risks will evolve depending on climate change and socio-economic development, entailing significant uncertainties. An uncertainty and sensitivity analysis of future tropical cyclone risks is thus vital for robust decision-making and model improvement. However, the outcomes of such uncertainty and sensitivity analyses are tied to the chosen model setup, warranting caution [...]

Wildfire smoke exposure and mortality burden in the US under future climate change

Wildfire activity has increased in the US and is projected to accelerate under future climate change. However, our understanding of the impacts of climate change on wildfire smoke and health remains highly uncertain. Here we quantify the mortality burden in the US due to wildfire smoke fine particulate matter (PM2.5) under future climate change. We construct an ensemble of statistical and machine [...]

Linking local climate scenarios to global warming levels: Applicability, prospects and uncertainties

Global warming levels (GWLs) are increasingly becoming a central concept in climate change studies. In recent years, their integrative quality for climate change impact analysis has been demonstrated, and methodological advancements have helped to compensate for some inherent shortfalls of the concept. However, their applicability at the regional level is debatable, and no study to date has [...]

Looking upstream: analyzing the protection of the drainage area of Amazon rivers

In the Amazon, aquatic ecosystems provide essential ecosystem services, including transportation, food, and livelihoods for millions of species. Land use changes and management impact these ecosystem services, and these impacts are not limited to the specific areas where they occur but propagate downstream along the drainage network. However, assessment of the accumulated human footprint upstream [...]

Site selection of desert solar farms based on heterogeneous sand flux

Guoshuai Li, Lihai Tan, Bao Yang, et al.

Published: 2023-10-09
Subjects: Atmospheric Sciences, Environmental Indicators and Impact Assessment, Geomorphology, Risk Analysis

Site selection for building solar farms in deserts is crucial and must consider the dune threats associated with sand flux, such as sand burial and dust contamination. Understanding the changes in sand flux can optimize the site selection of desert solar farms. Here we use the ERA5-Land hourly wind data with 0.1°×0.1° resolution to calculate the yearly sand flux from 1950 to 2022. The mean of [...]

Coral geochemical response to uplift in the aftermath of the 2005 Nias-Simeulue earthquake

On 28 March 2005, the Indonesian islands of Nias and Simeulue experienced a powerful Mw 8.6 earthquake and widespread co-seismic uplift and subsidence. In areas of coastal uplift (up to ~2.8 m), fringing reef coral communities were killed by exposure, while deeper corals that survived were subjected to habitats with altered runoff, sediment and nutrient regimes. Here we present time-series [...]

Social Vulnerability and Climate Risk Assessment for Agricultural Communities in The United States

Floods and droughts significantly affect agricultural activities and pose a threat to food security by subsequently reducing agricultural production. The impact of flood events is distributed disproportionately among agricultural communities based on their socio-economic fabric. Understanding climate-related hazards is critical for planning mitigation measures to secure vulnerable communities. [...]

Urban flooding causes billions of dollars in damages annually, with severe flood events becoming more frequent and destructive as our climate changes. While extreme weather is a primary driver of flooding, its consequences depend on the interconnectedness of urban systems - referred to as the Urban Multiplex, which includes the power grid, transportation network, natural surface water and [...]

The process of macroplastic (>0.5 cm) fragmentation results in the production of smaller plastic particles (micro- and nanoplastics), which threaten biota and human health and are difficult to remove from the environment. The global coverage and long retention times of macroplastic waste in fluvial systems (ranging from years to centuries) create long-lasting and widespread potential for its [...]
