Abstract

Global emission of carbon dioxide by subaerial volcanoes is calculated, using CO2 SO2 from volcanic gas analyses and SO2 flux, to be 34 ± 24 × 10l2 g CO2 yr from passive degassing and 31 ± 22 × 1012 g CO2 yr from eruptions. Volcanic CO2 presently represents only 0.22% of anthropogenic emissions but may have contributed to significant "greenhouse" effects at times in Earth history. Models of climate response to CO2 increases may be tested against geological data.
