I’m prepping material for another essay regarding the geochemistry of the Upper Mantle. A bewildering number of reactions are proceeding 24/7 in the Upper Mantle and are ALL exothermic (give off heat). None of this heat contribution has been included in the heat balance of the Earth.
Molten sulfides, molten silicates (mafic & ultramafic silicates) and molten carbonates. These melts proceed as simple acid/base reactions and decompositions to yield SO2, H2S, many other acid gases, Hydrogen, CO2, methane, and oil. At shallow depths, coal is produced much as charcoal, by cooking off the volatiles from heavy tars oozing up from below. The very term "fossil fuels†is in error.
Molten sulfides also produce metal sulfides. Such metal sulfides exist in the fumaroles (chimneys) of hydrothermal vents and are the basis of sulfur reduction, the energy source for anaerobic life.
The pH of your blood must be controlled tightly between 7.3 to 7.4. The pH of the ocean waters ranges from 8.1 to 8.2. Our distant anaerobic ancestors lingered just outside the scalding hot acidic discharge of hydrothermal vents.

And as Richard is always harping on, none of what occurs inside the Earth is well understood and certainly not included in any of the climate models.
Certainly it must have an effect. The internal workings of Venus most certainly are the root of that worthless planet's horrendous climate disaster.
