Rapid Removal of Atmospheric CO2 by Urban Soils

The measured calcium carbonate content of soils to a depth of 100 mm at a large urban development site has increased over 18 months at a rate that corresponds to the sequestration of 85 t of CO2/ha (8.5 kg of CO2 m–2) annually. This is a consequence of rapid weathering of calcium silicate and hydrox...
