Assessment of the Relationship between Passages of Tropical Cyclones and their Origins of Genesis for Managing Risk of the Coast of Bangladesh
Published: 2023-05-26
Subjects: Physical Sciences and Mathematics
To understand risk from upcoming tropical cyclones (TCs) of Bangladesh, Impact of Indian Ocean Dipole (IOD) on origins of TCs genesis historically over Bay of Bengal (BoB) should be considered. So, the correlation between Dipole Mode Indexes (DMI) and frequencies of TCs generated in BoB has been investigated for (1877-2018) era. Changes in decade-wise mean DMI have been found linearly correlated [...]
Global mean sea level higher than present during the Holocene
Published: 2023-05-24
Subjects: Earth Sciences, Other Earth Sciences, Physical Sciences and Mathematics
Global mean sea-level (GMSL) change can provide insight on how ice sheets, glaciers, and oceans respond to warming[1;2]. The Holocene (11.7 ka to present) marks a time when temperatures may have exceeded early industrial (1850 CE) values[3]. Evidence from Greenland[4] and Antarctica[5;6] indicates that both ice sheets retreated inland of their present-day extents during the Holocene, yet previous [...]
Exponential life-threatening rise of the global temperature
Published: 2023-05-23
Subjects: Atmospheric Sciences, Climate, Nature and Society Relations
Global temperatures are rising. This paper demonstrates for the first time that the global temperature increase has not been linear but is exponential with a doubling time of about 25 years. Both the amount of carbon dioxide produced by the combustion of fossil fuels and the amount of carbon dioxide in the atmosphere have also risen exponentially, with a similar doubling time. The exponential [...]
Chasing the water table: The impact of groundwater depletion on rural drinking water supply in peninsular India
Published: 2023-05-25
Subjects: Civil and Environmental Engineering
Groundwater overexploitation has been cited as one of the biggest threats to rural drinking water in India, but there is very little quantitative evidence. In this paper, we aim to understand (1) the extent of actual groundwater depletion and its impact on rural drinking water supply systems, (2) the primary driver of groundwater depletion and (3) the additional financial burden in finding new [...]

The derivation of the 1624 records is based on phenological observations provided by German Meteorological [...]
Salt‑rich versus salt‑poor structural scenarios in the central Northern Calcareous Alps: implications for the Hallstatt facies and early Alpine tectonic evolution (Eastern Alps, Austria)
Published: 2023-05-25
Subjects: Other Earth Sciences, Sedimentology, Tectonics and Structure
One of the most remarkable features of the central Northern Calcareous Alps (Eastern Alps, Austria) is the widespread presence of Upper Triassic deep-water carbonates (the Hallstatt facies) and Permo-Triassic evaporites resting on deep-water Middle Jurassic strata and their underlying Upper Triassic shallow-water carbonate platform successions. The Hallstatt facies and accompanying evaporites [...]
Integrated Formation Attenuation and Multiple Generator Identification from Multi-well VSP Data
Published: 2023-05-25
Subjects: Geophysics and Seismology
The Vertical Seismic Profile (VSP) is a widely used technique for extracting velocity information and seismic well tie purposes. However, the full potential of VSP data remains underutilized. This study explores the broader applicability of VSP data beyond its conventional usage by investigating its benefits for seismic data processing and interpretation. Advanced VSP products, incorporating [...]
Macroplastic fragmentation in rivers
Published: 2023-05-25
Subjects: Earth Sciences, Environmental Indicators and Impact Assessment, Geomorphology, Hydrology, Other Earth Sciences, Other Environmental Sciences, Sedimentology
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 [...]
Evolution of lake surface temperatures of high-altitude lakes in the European Alpine region under climate change
Published: 2023-05-25
Subjects: Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Lake Surface Temperature (LST) is a key characteristic that reflects meteorological and climatological influences on lakes. In general, there is limited LST data from high elevation lakes available as these areas are remote and not part of regular monitoring programs. Nonetheless, it is crucial to understand their response to climate warming for the development of effective management strategies [...]
The role of thermal notch erosion in forcing localised calving failure and short-term increases in velocity at a lake-terminating glacier in southeast Iceland
Published: 2023-05-25
Subjects: Glaciology
We utilised repeat high-resolution UAV-SfM surveys, alongside terrestrial photography acquired in-situ, to investigate, for the first time, the role of thermal notch erosion in forcing localised calving failure and subsequent short-term increases in velocity at a lake-terminating glacier. This data was acquired daily (where possible) across one week in July 2019 and two weeks in July 2021 to [...]
Local social-ecological context explains seasonal rural-rural migration of the poorest in a rural community in southwestern Bangladesh.
Published: 2023-06-02
Subjects: Environmental Studies
Bangladesh is one of the countries most affected by climate change. Internal migration is often presented as a response to environmental degradation in rural areas. Here, we hypothesise that climate-induced changes and adaptations impact local production and the local labour market, seasonally pushing out unskilled landless workers. We focus on different categories of livelihoods and their [...]

Published: 2023-05-26
Subjects: Public Health
The impact of climate change on reproductive decision-making is becoming a significant issue, with anecdotal evidence indicating a growing number of people factoring their concerns about climate change into their childbearing plans. Although empirical research has explored climate change and its relationship to mental health, as well as the motivations behind reproductive decision-making [...]
Formulating and Solving the Data-Consistent Geophysical Inverse Problem for Subsurface Modeling Applications
Published: 2023-05-26
Subjects: Earth Sciences, Geology, Geophysics and Seismology, Probability
Today, most probabilistic geophysical inverse problems are formulated using one of two methods: (1) conditional probability and Bayes’ Theorem, or (2) Tarantola’s theory of intersecting probability densities. More recently, a third inverse problem formulation based on pushforward probability measures was proposed, termed “data-consistent inversion”. Many practical problems can be cast into any of [...]
Impacts of Carbonate Buffering on Atmospheric Equilibration of CO2, δ13CDIC, and Δ14CDIC in Rivers and Streams
Published: 2023-05-28
Subjects: Biogeochemistry, Earth Sciences, Environmental Sciences, Hydrology
Rivers and streams play an important role within the global carbon cycle, in part through emissions of CO2 to the atmosphere. However, the sources of this CO2 and their spatiotemporal variability are difficult to constrain. Recent work has highlighted the role of carbonate buffering reactions that may serve as a source of CO2 in high alkalinity systems. In this study, we seek to develop a [...]
