Win, lose, or draw: evaluating dynamic thermal niches of northeast Pacific groundfish
Published: 2024-06-27
Subjects: Marine Biology
Understanding the dynamic relationship between marine species and their changing environments is critical for ecosystem based management, particularly as coastal ecosystems experience rapid change (e.g., general warming, marine heat waves). In this paper, we present a novel statistical approach to robustly estimate and track the thermal niches of 30 marine fishes along the west coast of North [...]
Regional differences in soil stable isotopes and vibrational features at depth in three California Grasslands
Published: 2024-06-27
Subjects: Life Sciences
There are major gaps in our understanding of how Mediterranean ecosystems will respond to anticipated changes in precipitation. In particular, limited data exists on the response of deep soil carbon dynamics to changes in climate. In this study we wanted to examine carbon and nitrogen dynamics between topsoils and subsoils along a precipitation gradient of California grasslands. We focused on [...]
Increasing precipitation due to climate change could partially offset the impact of warming air temperatures on glacier loss in the monsoon-influenced Himalaya until 2100 CE
Published: 2024-06-27
Subjects: Glaciology
Glacier volume in the Himalaya is projected to shrink by 53–70% during this century due to climate change. However, the impact of changes in precipitation amount and distribution on future glacier change remains uncertain because mesoscale meteorology is not represented in current models that project glacier change. We explored the combined effects of past and future changes in air temperature [...]
Regionally Developed Giant Sand Injection Complexes in the Northern North Sea
Published: 2024-06-26
Subjects: Education
The Northern North Sea (NNS) is an archetype Giant Injected Sand Province (GISP). Previous studies have documented individual stratigraphically-bound injectite complexes in the North Sea and beyond. Despite two decades of continuous studies, there are still speculations in terms of parent sand identification, visible pathways, fluid source, overpressure generation mechanisms and triggers. This [...]
State-dependency of dynamic and thermodynamic contributions to effective precipitation changes
Published: 2024-06-26
Subjects: Climate, Oceanography and Atmospheric Sciences and Meteorology
Reliable projections of the future hydrological cycle are needed for designing adaptation and mitigation measures under global warming. However, uncertainties in the projected sign and magnitude of effective precipitation changes (precipitation minus evaporation, P-E) remain high. Here, we examine the state-dependency of circulation, temperature, and relative humidity contributions to P-E changes [...]
Lidar-based snow monitoring: cable car deployment in the Austrian Alps
Published: 2024-06-26
Subjects: Environmental Monitoring, Fresh Water Studies, Water Resource Management
Traditional methods for surveying the spatial and temporal distribution of snow are often time-consuming, costly, and potentially hazardous. To address these challenges, we propose a novel approach utilizing a newly developed sensor system based on cost-effective industrial lidar sensors. This system is designed to be mounted on cable cars, enabling continuous envi- ronmental scanning during [...]
A space-time simulator for hourly wind and solar energy fields
Published: 2024-06-26
Subjects: Engineering
Spatially distributed renewable energy generation poses unique risks to power systems since the aggregate amount of energy produced in any hour depends on the spatial correlation structure of the sources. Moreover, the spatial correlation structure can vary with the time of day and season and depend on the state of the large-scale climate. These features pose a challenge for resource adequacy [...]
Radiometric dating (40Ar/39Ar and 14C), compositions, and erupted volumes of volcanoes of the Valle de Santiago area (Michoacán-Guanajuato Volcanic Field, México)
Published: 2024-06-25
Subjects: Physical Sciences and Mathematics
The Valle de Santiago (VS) area is located in the NE sector of the Michoacán-Guanajuato Volcanic Field, within the central part of the Trans-Mexican Volcanic Belt (TMVB). Based on geological mapping of a ~2,800 km2 quadrangle, 40Ar/39Ar and radiocarbon dating, morphometry, and whole-rock chemical and petrographic analyses of the volcanic products, we established the stratigraphy and eruptive [...]
Fracture criteria and tensile strength for natural glacier ice calibrated from remote sensing observations of Antarctic ice shelves
Published: 2024-06-24
Subjects: Glaciology
The conditions under which ice fractures and calves icebergs from Antarctic ice shelves are poorly understood due largely to a lack of relevant observations. Though previous studies have estimated the stresses at which ice fractures in the laboratory and through sparse observations, there remains significant uncertainty in the applicability of these results to naturally deforming glacier ice on [...]
Shallow storage conditions at Krafla IDDP-1 revealed by rhyolite-MELTS geobarometry, and implications for global shallow magmatism
Published: 2024-06-24
Subjects: Earth Sciences, Geochemistry, Geology, Other Earth Sciences, Volcanology
Identifying the storage depths of melt-dominated magma bodies prior to eruption is critical for understanding magma transport, eruption hazards, and magma body longevity. Rhyolite-MELTS has been used effectively to calculate pre-eruptive storage pressures for silicic magma bodies in the upper crust (~100-350 MPa), but its precision and accuracy in very low-pressure systems (<100 MPa) has not [...]
One Belt, Many Roads: Investigating China’s Foreign Investment and Land-use Impacts in Southeast Asia
Published: 2024-06-22
Subjects: Environmental Indicators and Impact Assessment, Environmental Sciences, Environmental Studies, Natural Resource Economics
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 [...]
How Will Precipitation Characteristics Associated with Tropical Cyclones in Diverse Synoptic Environments Respond to Climate Change?
Published: 2024-06-22
Subjects: Atmospheric Sciences, Climate, Meteorology, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Landfalling tropical cyclones (TCs) can produce large rainfall totals which lead to devastating flooding, loss of life, and significant damage to infrastructure. Many studies have examined future changes in TC precipitation, however few have considered changes owing to differences in the synoptic environment during landfall. Here we focus on three North Atlantic TCs that impacted the southeastern [...]
Focus of the IPCC Assessment Reports Has Shifted to Lower Temperatures
Published: 2024-06-22
Subjects: Life Sciences
We focus on how different global temperature increases represented in IPCC reports have shifted over time. While the first four assessment reports had a roughly equal focus on temperatures above and below 2°C, the more recent fifth and sixth assessment reports have a considerably stronger focus on warming below 2°C. This is concerning as warming above 2°C is more likely given current emissions [...]
Effect of climate variability, crop production, and household food insecurity on malnutrition among women: A mediation analysis from a drought-prone area in Southern Ethiopia
Published: 2024-06-22
Subjects: Medical Sciences
Malnutrition is viewed as one of climate change's five most considerable adverse health impacts. As many previous studies have shown correlations between climate, food production, and social factors on the nutritional status of women, we hypothesized a causal effect of climate variations on crop production, household food security, and our outcome, the nutritional status of adult women. Using a [...]
