Now, a team of scientists show that CO<sub>2</sub> is efficiently liberated from limestones by volcanic activity and released into the atmosphere. This limestone-derived CO<sub>2</sub> is likely a significant contributor to the global carbon cycle, but has so far been underestimated in respect to climate effects.
