The USGS analysts do not include MID OCEAN RIDGES or RIFTS in their computations considering them to be imponderable.

Still, they know they emit CO2 pretty much the same way as volcanos. With the ridges several hundred times larger than the total of all the volcanos on Earth, it's pretty easy to take their 20% volcanic estimation and recompute it to a number that DWARFS human CO2 emissions.

The USGS analysts do not include MID OCEAN RIDGES or RIFTS in their computations considering them to be imponderable.

So they are ignoring 70% of Earth's surface?
