Er, what Scientists say that? I've often heard this claim about volcanos, CO2 and human output and yet, every time I look it up, Human CO2 emissions dwarf that of any volcano.
Also, why would these "scientists" you refer too (yet don't quote or link) think that if this volcano did indeed emit more CO2 than humans have in forever, why would they say it would cause global cooling? I am aware of the mechanics of how a volcano would cause global cooling, but it has sod all to do with CO2...
The Pinatubo eruption was estimated to have emitted only a modest 42 megatons CO2 (Gerlach 1996), a small fraction of the total natural and anthropogenic annual emissions. M
However, we do know that the Mount Pinatubo eruption in 1991 (2nd largest volcanic eruption of the 20th century) emitted about 10 gigatons
