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.

Rock organic carbon oxidation CO2 release offsets silicate weathering sink. [PDF]
Nature, 2023 Mountain uplift and erosion have regulated the balance of carbon between Earth’s interior and atmosphere, where prior focus has been placed on the role of silicate mineral weathering in CO_2 drawdown and its contribution to the stability of Earth’s ...

Global silicate weathering flux overestimated because of sediment-water cation exchange. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance Large rivers transport water and sediment to floodplains and oceans, supplying the nutrients that sustain life. They also transport carbon, removed from the atmosphere during mineral dissolution reactions, which is thought to provide a key ...

Trends and Transitions in Silicate Weathering in the Asian Interior (NE Tibet) Since 53 Ma
Frontiers in Earth Science, 2022 The relationship between silicate weathering, Tibetan Plateau uplift, and global cooling during the Cenozoic provides a valuable case study for understanding the interaction of tectonics and climate.

High‐resolution mapping of the global silicate weathering carbon sink and its long‐term changes
Global Change Biology, 2022 Climatic and non‐climatic factors affect the chemical weathering of silicate rocks, which in turn affects the CO2 concentration in the atmosphere on a long‐term scale.

K isotopes trace temporal silicate weathering intensity [PDF]
Nature CommunicationsSilicate 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 ...

A revised model for silicate weathering
Goldschmidt2023 abstracts, 2023 Silicate weathering has long been considered an important sink for the carbon cycle and a thermostat for the earth habitability. Many factors including climate, tectonic, and biology affect this process and their interaction makes it complex to study ...

Quantifying silicate weathering fluxes in rivers [PDF]
Goldschmidt2021 abstracts, 2021 Distinction of the inputs into rivers from silicate minerals, carbonate minerals, and salts is critical to estimating the silicate weathering fluxes thought to act as a major feedback controlling the Earth's climate on long timescales. Distinction of the

Negative CO2 emissions via enhanced silicate weathering in coastal environments. [PDF]
Biol Lett, 2017 Negative emission technologies (NETs) target the removal of carbon dioxide (CO2) from the atmosphere, and are being actively investigated as a strategy to limit global warming to within the 1.5–2°C targets of the 2015 UN climate agreement.

Silicate weathering in anoxic marine sediments [PDF]
Mineralogical Magazine, 2008 Two sediment cores retrieved at the northern slope of Sakhalin Island, Sea of Okhotsk, were analyzed for biogenic opal, organic carbon, carbonate, sulfur, major element concentrations, mineral contents, and dissolved substances including nutrients ...
