Basalt weathering may remove far less CO₂ than projected
Spreading finely crushed basalt across farmland has been promoted as a relatively simple way to remove large quantities of carbon dioxide from the atmosphere. But a new study led by Cornell researchers suggests the real-world potential of this method, known as enhanced weathering, may be far smaller than widely cited estimates.
