Persistent silicate weathering and carbon dioxide uptake in eolian drylands since the late Pliocene

Semi-arid and arid regions are largely omitted from long-term geological-scale carbon budgets due to the assumed weakness of silicate weathering. Here we reconstruct annual carbon dioxide (CO₂) consumption by silicate weathering (CO₂(SIW)) using red clay and loess–paleosol sequen...
