Enhanced silicate weathering during glacial lowstands: new evidence from shelf sediments in the northern South China Sea

Quaternary Science Advances
The enhanced silicate weathering on tropical continental shelves has been linked to the exposure of unconsolidated sediments during glacial lowstands, contributing to atmospheric CO2 consumption.

Sidelining Mitigation: Climate Delay Discourses Among Municipal Legislators in Southeastern Brazil

Environmental Policy and Governance, EarlyView.
ABSTRACT This study investigates how municipal legislators frame climate mitigation and how these framings shift responsibility, narrow the perceived scope of municipal authority, and reduce the urgency or feasibility of local action. We analyzed 31 interviews with city councilors serving on Permanent Environmental Committees across municipalities in ...

Kinetics of element release by weathering in soils of southern Ecuador: A comparison among different climatic and land-use regimes

Geoderma
To predict future changes in nutrient availability in the young soils of the tropical Andes, it is important to study the response of weathering rates to climate and land-use change.

Sensitivity of the global carbonate weathering carbon-sink flux to climate and land-use changes [PDF]

, 2019
The response of carbonate weathering carbon-sink flux (CCSF) to its environmental drivers is still not well understood on the global scale. This hinders understanding of the terrestrial carbon cycle.

When Policy Is the Hazard: Institutional Legitimacy and Climate Risk Attribution Among Farmers in Water Stressed California

Environmental Policy and Governance, EarlyView.
ABSTRACT This study examines how farmers perceive and respond to climate policy risk in the context of drought and argues that understanding such responses is as important as understanding farmer reactions to the biophysical impacts of climate change.

Performance Comparison of Monocrystalline, Polycrystalline, Low Concentrated, and Bifacial PV Modules in a Particular Geographic Location of South India

Energy Science &Engineering, EarlyView.
This study aims to conduct a performance comparison of irradiation and temperature on different commercially available PV modules like PPVM, MPVM, LPVM, and BPVM. Here, the TPVM is not considered in the analysis due to its toxic nature. This study has considered the LPVM because researchers have not focused on it due to the higher area requirement for ...

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

Energy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents
