Mountain erosion may add CO2 to the atmosphere

Scientists have long known that steep mountain ranges can draw carbon dioxide (CO2) out of the atmosphere — as erosion exposes new rock, it also starts a chemical reaction between minerals on hill slopes and CO2 in the air, ‘weathering’ the rock and using CO2 to produce carbonate minerals like calcite.
