You might want to expand your "view" to include the 1000s of known
active under-sea and under-ice volcanos.

These are being found in the eastern Pacific basic (over 1,600 just
a short bit off the coast of Peru), under the North Pole, under the
South Pole, under Greenland, and many, many other places by ESA's
satellites and many countries' research vessels and submarines. One
correspondent at the ESA wrote he was amazed to see volcanic fires
through miles of clear ice at the South Pole in their sat's imagery.

Think what happens to a pot of ice placed on a kitchen stove after
the stove's burner is turned on -- it melts.

And volcanos emit a LOT of CO2 (among other things).
