“…Carbon can chemically sequester in silicate materials to form clay minerals, which are preferentially removed during erosion and transported to the oceans (Colbourn et al, 2015). The drawdown of atmospheric CO 2 is dependent on available surface area for weathering, local erosion rates, and land surface reactivity (Rugenstein et al, 2019). Temperature, humidity, precipitation rates and acidity of the weathering environment all control erosion rates and are in turn controlled by climate; greater erosional rates and CO 2 drawdown is expected at lower latitudes where precipitation rates and temperature are higher (e.g., Amiotte Suchet et al, 2003).…”

“…Interestingly, Li isotopes (the ratio of 7 Li/ 6 Li) have been used by Earth scientists and geochemists since, when measured in rivers and soils, they provide key information on soil sustainability and weathering rate on continents, and therefore on the carbon cycle. They are considered as a key isotope proxy of unraveling why and how global climate could be regulated over geological timescale 1722 . Thus, for all these reasons, it becomes increasingly important and urgent to quantify the amount of environmental Li that comes from anthropogenic activities.…”
