Geologic hydrogen (H2) deposits could be a source of climate friendly energy. In this work, we perform a prospective life cycle assessment of a generic geologic hydrogen production and processing system. While it is still too early in the development cycle to estimate precise life-cycle carbon intensities (CI) we can use fundamental engineering physics and chemistry to estimate CI. Our baseline [...]

In the past few years, it has been established that remote sensing of wetlands change analysis studies would require careful examination of tidal flooding produced uncertainties in satellite datasets. Tide flagging and filtering mechanisms are required to reduce per-pixel variabilities and errors in change detection. We present a technical note summarizing the potential impact of a lack of tide [...]

This paper examines the different ways in which the Information and Communications Technology (ICT) sector negatively affects the environment. To capture environmental externalities beyond the common but limited carbon footprint, a novel holistic framework of digital sustainability was created - the Digital Environmental Footprint (DEF). To apply and test the DEF, the ICT sector was evaluated [...]

Mountain rivers are typically seen as relatively pristine ecosystems, supporting numerous goods (e.g., water resources) for human populations living not only in the mountain regions but also downstream from them. Recent evidence suggests, however, that mountain river valleys in populated areas can be substantially polluted by macroplastic (plastic item > 5 mm). It is, however, unknown how [...]

We quantify potential air pollution exposure reductions resulting from U.S. federal carbon policy, and consider the implications of resulting health benefits for exposure disparities across racial/ethnic groups. We assess reductions in carbon dioxide (CO2) emissions of 50% in 2030 relative to 2005 levels, comparable in magnitude to the 2022 Inflation Reduction Act. Using energy-economic scenarios [...]

Climate change and development of data-oriented methods are appealing for new climate classification schemes. Based on the most widely used Köppen-Geiger scheme, this article proposes a neural network based climate classification method from a data science perspective. In conventional schemes, empirically handcrafted rules are used to divide climate data into climate types, resulting in certain [...]

No-till in agricultural arable systems is a practice that offers benefits to soil health. Combined with methods such as the incorporation of crop residues and manures, no-till can influence the dynamics of soil organic carbon (SOC) and organic matter (SOM), crop productivity and nutrient status. These turnovers are shaped by spatial and temporal factors and associated microbial mineralisation [...]

PURPOSE. Bioenergy with carbon dioxide removal (CDR) is increasingly presented as an efficient way to mitigate climate change. This study set out to determine under which circumstances and methodological choices CDR bioenergy systems are preferable over a reference bioenergy system from a climate change mitigation perspective. In addition, the CDR systems investigated were compared to each [...]

The Maros-Pangkep karst in southwest Sulawesi, Indonesia, contains some of the world’s oldest rock art. However, the Pleistocene images survive only as weathered patches of pigment on exfoliated limestone surfaces. Salt efflorescence underneath the case-hardened limestone substrate causes spall-flaking, and it has been proposed that the loss of artwork has accelerated over recent decades. Here, [...]

Groundwater pumping can cause reductions in streamflow (“streamflow depletion”) that must be quantified for conjunctive management of groundwater and surface water resources. However, streamflow depletion cannot be measured directly and is challenging to estimate because pumping impacts are masked by streamflow variability due to other factors. Here, we conduct a management-focused review of [...]

From March 30th to April 9th, 2021, 814 million liters of legacy phosphate mining wastewater and marine dredge water from the Piney Point facility were released into lower Tampa Bay (Florida, USA). This resulted in an estimated addition of 186 metric tons of total nitrogen, exceeding typical annual external nitrogen load estimates to lower Tampa Bay in a matter of days. Elevated levels of [...]

A major coal mine project in Queensland, Australia, is currently under review. It is planned to be located about 10 km away from the Great Barrier Reef World Heritage Area (GBRWHA). Sediment dispersal patterns and their impact on marine ecosystems have not been properly assessed yet. Here, we simulate the dispersal of different sediment types with a high-resolution ocean model, and derive their [...]

Climate change has driven an increase in the frequency and severity of fires in Eurasian boreal forests. A growing number of field studies have linked the change in fire regime to post-fire recruitment failure and permanent forest loss. In this study we used four burnt area and two forest loss datasets to calculate the landscape-scale fire return interval (FRI) and associated risk of permanent [...]

Reproducibility, the extent to which consistent results are obtained when an experiment or study is repeated, sits at the foundation of science. The aim of this process is to produce robust findings and knowledge, with reproducibility being the screening tool to benchmark how well we are implementing the scientific method. However, the re-examination of results from many disciplines has caused [...]

The Campania region has been recurrently hit by severe landslides in volcanoclastic deposits. The city of Naples, and in particular the Camaldoli and Agnano hills, also suffered several landslide crises in weathered volcanoclastic rocks as a consequence of intense rainfalls or wildfires. This work provides an updated landslide database for the suburbs of Naples. The obtained database consists of [...]
