  abstract = {{T}he global carbon dioxide ({CO}2) flux from subaerial volcanoes remains poorly quantified, limiting our understanding of the deep carbon cycle during geologic time and in modern {E}arth. {P}ast attempts to extrapolate the global volcanic {CO}2 flux have been biased by observations being available for a relatively small number of accessible volcanoes. {H}ere, we propose that the strong, but yet unmeasured, {CO}2 emissions from several remote degassing volcanoes worldwide can be predicted using regional/global relationships between the {CO}2/{S}-{T} ratio of volcanic gases and whole-rock trace element compositions (e.g., {B}a/{L}a). {F}rom these globally linked gas/rock compositions, we predict the {CO}2/{S} {T} gas ratio of 34 top-degassing remote volcanoes with no available gas measurements. {B}y scaling to volcanic {SO}2 fluxes from a global catalogue, we estimate a cumulative "unmeasured" {CO}2 output of 11.4 +/- 1.1 {M}t/ yr (or 0.26 +/- 0.02.10(12) mol/yr). {I}n combination with the measured {CO}2 output of 27.4 +/- 3.6 {M}t/yr (or 0.62 +/- 0.08.10(12) mol/yr), our results constrain the time-averaged (2005-2015) cumulative {CO}2 flux from the {E}arth's 91 most actively degassing subaerial volcanoes at 38.7 +/- 2.9 {M}t/yr (or 0.88 +/- 0.06.10(12) mol/yr).},
