“…Also, mass shifts have been linked with the motions of the tectonic plates, which are influenced by the gravitational pulls from the moon and sun thereby amplifying the climate change cycle. Not forgetting geomorphic processes, which affect landscapes and are known to result in transfers that could include relief reductions, by way of volcanism and tectonic or isostatic uplifts, and the deposition of eroded materials in different sedimentary environments (Cendrero et al, 2022). Volcanoes have been reported to erupt in locations with relatively high concentrations of magma, which is synonymous with greater mass and higher gravity; monitoring changes in the gravitational field of active volcanoes can, therefore, provide insights into volcanic activities (Poland & Carbone, 2016;Yan, 2016).…”

“…(Lamon et al, 2009;von Schneidemesser et al, 2015). Significantly, denudation and geomorphic processes, for instance, which involve the transfer of solid and/or dissolved materials by different agents, such as continental and ocean waters, ice, air, plants, animals and humans, from one part of Earth"s surface to another under the influence of gravity, and wind and water currents, are reported to be at least one order of magnitude greater due to human-triggered land surface alterations than nature-induced denudational processes (Cendrero et al, 2022;Eekhout & de Vente, 2022).…”

World climate continues to deteriorate at varying rates in spite of different anthropogenic mitigative and adaptive interventions. Conversely, the gravitational force fields of the sun and moon hold Earth in orbit, amongst others. Herein, we explore the impacts of changes in these gravitational fields on global climate and examine their influences on natural events, such as ocean tides, volcanoes, geomagnetic storms and movement of tectonic plates. Beyond reports on greenhouse effect and mass transport, we discuss the influence of gravity on tidal bulges, melting glaciers, condensable atmosphere and other events, such as El Niño and La Niña, and correlate their typically subtle impacts on climate worldwide with variations in Earth’s gravity. The intention is to highlight other causative factors implicated in climatic change without diminishing the contributions of greenhouse gasses and other factors, which are currently regarded, by specialists and lay-public alike, as the major culprits of climate change. We submit that the shifts in Earth’s gravitational fields to sustain equilibrium and remain in orbit can manifest as perturbations of atmospheric temperatures, pressures and air concentrations as well as volume changes and ion effects; in hydrological bodies, and are some of the non-anthropogenic agents driving changes in global climate. We surmise, therefore, that the influence of changes in gravity, albeit subtle, on climate change is significant. It is envisaged that highlighting these subtle agents of change would intensify efforts toward ameliorating and/or eliminating drastic and deleterious changes in climate as well as at embracing adaptive measures at local and international levels.

“…Determination of sediment budgets in drainage systems of various scales is crucial for comprehending natural processes and dynamics accountable for sediment production (sediment generation) and transport (sediment flux) and for investigating the response of sediment routing systems to perturbation due to external forcing by tectonics and climate (Caracciolo, 2020, and references therein). Furthermore, sediment budgeting allows quantifying anthropic stress on fluvial, coastal and marine ecosystems in terms of nutrient supply, landscape evolution and pollution, and predicts future scenarios of human impact on nature (e.g., Best, 2019;Cendrero et al, 2022;Dethier et al, 2022;Eschenfelder et al, 2023;J.

This study investigates the upper Magdalena river basin (Colombia), which is characterized by tectonic activity, tropical climate, heterogeneous lithological assemblages, and anthropic influence. It aims to comprehend factors controlling sediment generation, flux, and composition by incorporating petrographic data from 27 recent fluvial samples along with geochemistry, geomorphological parameters, historical precipitation, land cover, landsliding and suspended sediment load data. The analysis shows mismatches between sand composition and drainage lithology distribution. A new set of endmember mixing models is presented, quantifying the impacts of erodibility, sand generation potential (related to lithology), and sediment connectivity between hillslopes and river outlets (related to geomorphology). Results show enhanced sediment generation from sedimentary rocks (up to 40%) due to high erodibility, and decreased sediment flux from low‐ to medium‐grade metamorphic rocks (up to 60%) due to controlling morphometric parameters. Overrepresentation of plutonic and high‐grade metamorphic rocks and underrepresentation of volcanic rocks (up to 100%) are controlled by mineralogical and textural parameters. Enhanced landsliding activity in areas with volcanic activity occasionally overshadows basin‐wide compositional trends driven by morphological and lithological characteristics, as it controls rare overrepresentation of volcanic and low‐grade metamorphic detritus in the sand fraction. Sediment retention by hydroelectric dams significantly decreases suspended sediment flux by 30%, while deforestation plays a minor role in sediment flux. This study underscores the importance of coupling sediment generation, geomorphology and the distribution of stochastic events related to seismic activity in any sediment production‐focused study and for developing numerical models in Quantitative Provenance Analysis (QPA).

“…Humans have substantially altered global sediment fluxes and are recently causing a higher sediment transport than all natural processes combined (Cooper et al, 2018; Hooke, 2000; Price et al, 2011). This includes sediment mobilisation, sediment connectivity as well as deposition (Cendrero et al, 2022; Goudie, 2020; Owens, 2020). Influence on sediment transport has increased substantially, especially in the second half of the 20th century (Goudie, 2020; Lewin, 2013).…”

“…Influence on sediment transport has increased substantially, especially in the second half of the 20th century (Goudie, 2020; Lewin, 2013). Human‐induced sediment mobilisation is caused by direct effects such as construction (Lucas‐Borja et al, 2021; Wohlers & Damm, 2021) and mining (Tarolli & Sofia, 2016; Wilkinson, 2005) and indirect effects such as LULC (land use and land cover) changes (Cendrero et al, 2022; Dethier et al, 2022; Venter et al, 2016) and climate change (Borrelli et al, 2020; Goudie, 2020).…”

Reservoirs have become an important component in the worldwide river sediment flux. Reservoirs prevent downstream sediment transport and have become a major sediment sink. In this study, sediment deposition during the last 115 years in the Urft Reservoir in western Germany is reconstructed. The Urft Reservoir is the oldest reservoir in the Eifel Mountains and was almost completely drained in 2020. This enabled a detailed mapping of the lake bottom using an unmanned aerial system and the computation of a high‐resolution digital surface model. Topographic maps with a nominal resolution of 1:1000 from the time prior to the construction of the dam (around 1900) were used to construct a pre‐reservoir elevation model. A digital elevation model of difference (DoD) was calculated from these two datasets for the reservoir floor (0.72 km2). Based on the DoD, a net sediment accumulation of 1.16 × 106 m3 was calculated alongside a propagated volume error of 6.91 × 105 m3, resulting in a mean accumulation of 1.54 m. Conservative vertical error propagation results in an average level of detection (LoD) of 1.8 m. In contrast, the comparison of the DoD with 47 cores in the upper part of the reservoir showed a mean difference of −0.11 m, indicating a high, independently assessed accuracy of the DoD. Three depositional hotspots were identified in the reservoir. One is close to the Urft dam where very fine sediments are draped across the pre‐reservoir topography. Two areas are related to reservoir management. Sediment deposition in the Urft Reservoir has been comparably low in comparison to other regions globally, resulting in a 3.25% ± 1.93% loss of reservoir volume between 1905 and 2020. To analyse the effect of strong flooding events, a subset of the reservoir was analysed after an extreme event in July 2021, but accumulation did almost entirely not exceed the LoD.
