It will probably exceed St. Helens, greatly, in terms of climate impact.

But it takes 100 years to get co2 out of the atmosphere.

These are a different animal than the common stratovolcanos among which are Pinatubo, El Chicon, St. Helens, etc, lying above subducting plates. The eruption is obviously plinic, therefore VEI starts at 4. In coming weeks we might find it to continue continuously, then intermittently for a few months. Plinic eruptions require upto 20% of the mass to be H2O and CO2 gas to support the column, H2S can also be present in quantity. Tambora, a stratovolcano last erupting at VEI 7, and another unidentified major eruption ca. 1812, raised CO2 worldwide to 450ppm. This eruption is believed to be the second major eruption of this small caldera so no real history has been established. If it proceeds to class, a VEI of 6 could easily result. This would definitely be felt worldwide, in the SH anyway. This is a caldera volcano residing, no doubt, astride a rifting fault.
