Alkalinity affects uptake of carbon dioxide and contributes to long-term buffering capacity of oceans, suggests model
If climate change causes more rain, this promotes the weathering of rocks and thus the erosion of the soil. The dissolved substances reach the sea via rivers. A new model from Helmholtz-Zentrum Hereon shows that the process ...

Carbonatitic liquid acts as medium for transferring carbon from slab to subarc mantle
Deep carbon cycling at subduction zones affects the long-term habitability of Earth's surface by regulating atmospheric CO2 concentrations. How the carbon is transferred from the slab to the subarc mantle has thus far eluded ...
