Reply to comment by r2k-in-the-vortex in How much does the liquid magma of the Earth affect it's surface temperature? by tripperfunster

Do you have more info on how volcanic carbon emissions affect foliage? It seems like there would still be plenty of carbon to go around and that volcanos just contribute more to the carbon cycle. Or is it part of the cycle? Like some carbon is sequestered due to tectonic activity and then released by volcanos?

Carbon is sequestered because sedimentary rocks form which contain a lot of carbon, without volcanic emissions to offset that, atmosphere would slowly(over millions of years) run low on carbon. That has happened in geologic history resulting in several periods of snowball Earth, sea ice all the way to equator. To break out of this state enough volcanic activity had to happen for CO2 concentrations in atmosphere to build up again.
