Throughout Earth's history, CO2 is thought to have exerted a fundamental control on
environmental change. Here we review and revise CO2 reconstructions from boron isotopes …

Concealed deep beneath the oceans is a carbon conveyor belt, propelled by plate tectonics.
Our understanding of its modern functioning is underpinned by direct observations, but its …

Silicate weathering as an important negative feedback can regulate the Earth's climate over
time, but much debate concerns its response strength to each climatic factor and its …

Direct evidence of intense chemical weathering induced by volcanism is rare in sedimentary
successions. Here, we undertake a multiproxy analysis (including organic carbon isotopes …

Ocean alkalinity enhancement (OAE) has recently gained attention as a potential method for
carbon dioxide removal (CDR) at gigatonne (Gt) scale, with near-coast OAE operations …

Much work has been undertaken quantifying the abundance of phyllosilicate clay minerals
in soils, sediments and rocks of Earth's crust. However, no detailed global compilation of …

Silicate weathering is critical to global carbon cycle and climate change, and has attracted
considerable attention in Earth science studies. Chemical weathering intensity evaluation …

Map** of soil organic matter (SOM) in cultivated land is one of the important aspects of
digital soil map**, and its results are of great significance for agricultural precision …

Biosiliceous cherts hosting the transformation of biogenic silica to paracrystalline opal-CT,
deposited in the low-latitude realms of Jurassic to Neogene, were recently interpreted as …

This paper reviews global records of anoxic events of the Middle Devonian–earliest
Mississippian, as well as the possible triggers and controls of these events. These “anoxic …
