Global carbon dioxide emission to the atmosphere by volcanoes

Global emission of carbon dioxide by subaerial volcanoes is calculated, using CO 2 SO 2 from volcanic gas analyses and SO 2 flux, to be 34 ± 24 × 10 l2 g CO 2 yr from passive degassing and 31 ± 22 × 10 12 g CO 2 yr from eruptions. Volcanic CO 2 presently represents only 0.22% of anthropogenic emissi...
