Can Anyone estimate Co2 from 1 volcanoes, then multiply by 200 ? Sure could the help. One guess is as good as another.

Since the CO2 emitted from a volcanic vent varies with each volcano, and that rate varies over time for a single volcano, no.

You are the LAST one to claim a randU fallacy, what with the stuff YOU make up.

Why are you interested in cobalt?

That's pretty funny. But we aren't supposed to attack typos.

Found a review article that estimates global geologic CO2 emissions: Quoting

"Summing the extrapolated passive plume, diffuse degassing, lake degassing global estimates and emissions from inactive, hydrothermal and tectonic structures produces a total subaerial volcanic flux of 540 Mt/yr, and a global emission (including MOR emissions) of 637 Mt/yr (Table 6). Thus global volcanic CO2 fluxes are only ~1.8% of the anthropogenic CO2 emission of 35,000 Mt per year (Friedlingstein et al. 2010)."

The article itself, published in a science journal, is at http://www.minsocam.org/msa/rim/RiMG075/RiMG075_Ch11

The article does emphasize that these are estimates. Measurements have certainly been made, but not in enough different places for long enough. Read some of the text and appreciate the difficulties in making the measurements. Interesting is table 7, showing how the estimated amount of volcanic/geologic CO2 emissions have increased over the years.

Also, it's possible that results from OCO-2, the orbiting carbon observatory may, in time, refine the estimates considerably.
