A global temperature control of silicate weathering intensity [PDF]

Nature Communications, 2022
How silicate weathering responds to and regulates Earth’s climate remain controversial. This study suggests the primary control of temperature on weathering intensity globally and the temperature-weathering feedback may be stronger in cold Earth.

K isotopes trace temporal silicate weathering intensity [PDF]

Nature Communications
Silicate weathering alters the biogeochemical compositions of the lithosphere, hydrosphere, and atmosphere, and thereby regulates both nutrient cycling and habitable temperatures on Earth, but tracing silicate weathering effectively remains a challenge ...

Magnetic susceptibility controlled by climate-driven weathering intensity

BSGF - Earth Sciences Bulletin
Magnetic susceptibility (MS) variations are commonly attributed to eustatic and/or climatic changes that impact the delivery of fine-grained detrital magnetic minerals.

Rhenium Isotopes Record Oxidative Weathering Intensity in Sedimentary Rocks

Geochemistry, Geophysics, Geosystems
Oxidative weathering of organic carbon in sedimentary rocks is a major source of CO2 to the atmosphere over geological timescales, but the size of this emission pathway in Earth's past has not been directly quantified due to a lack of available proxy ...

Feedbacks between the formation of secondary minerals and the infiltration of fluids into the regolith of granitic rocks in different climatic zones (Chilean Coastal Cordillera) [PDF]

Earth Surface Dynamics, 2023
Subsurface fluid pathways and the climate-dependent infiltration of fluids into the subsurface jointly control the intensity and depth of mineral weathering reactions.

Chemical weathering detection in the periglacial landscapes of Maritime Antarctica: New approach using geophysical sensors, topographic variables and machine learning algorithms

Geoderma, 2023
The chemical weathering intensity in Antarctica is underestimated. As the chemical weathering intensity increases, hydrological, geochemical and geophysical changes occur in the different environmental spheres and at their interfaces through reactions ...

The Influences of Climatic and Lithological Factors on Weathering of Sediments in Humid Badland Areas

Frontiers in Earth Science, 2022
Climate variables including temperature, rainfall intensity, rainfall acidity, and lithological properties are among the most important factors affecting rock weathering.

Chemical Weathering Intensity as a Reliable Indicator for Southwest Summer Monsoon Reconstruction: Evidence From Clay Minerals of Qionghai Lake Sediments Since the Last Glacial Maximum

Geochemistry, Geophysics, Geosystems, 2023
Studying the evolution history of the southwest summer monsoon (SSM) throughout geological time, particularly during its strongest period in the Holocene, can improve our understanding of its variation and driving mechanisms, and even help predict future

Assessing the Impact of Weather on Traffic Intensity [PDF]

Weather, Climate, and Society, 2010
Abstract This paper focuses on the effect of weather conditions on daily traffic intensities (the number of cars passing a specific segment of a road). The main objective is to examination whether or not weather conditions uniformly alter daily traffic intensities in Belgium, or in other words whether or not road usage on a particular ...
