Precision measurements show that sub-glacial volcanoes have been greatly underestimated as an ongoing source of carbon dioxide emissions. When will they re-do the calculations?

Recent research suggests the volume of volcanic CO2 being emitted into the atmosphere is far greater than previously thought, challenging man-made warming, says ClimateChangeDispatch.
The cornerstone principle of the global warming theory, anthropogenic global warming (AGW), is built on the premise that significant increases of modern era human-induced CO2 emissions have acted to unnaturally warm Earth’s atmosphere.
A warmed atmosphere that directly, or in some cases indirectly fuels anomalous environmental disasters such as ocean warming, alteration of ocean chemistry, polar ice sheet melting, global sea level rise, coral bleaching and most importantly dramatic changes in climate.
There are numerous major problems with the AGW principle.
Identification of Volcanic vs. Man-made CO2
Natural volcanic and man-made CO2 emissions have the exact same and very distinctive carbon isotopic fingerprint.
It is therefore scientifically impossible to distinguish the difference between volcanic CO2 and human-induced CO2 from the burning of fossil fuels.
This major problem with the AGW principle has been rationalized away by consensus climate scientists who insist, based supposedly reliable research, that volcanic emissions are minuscule in comparison to human-induced CO2 emissions (Gerlach 1991).
Terrance Gerlach’s volcanic CO2 calculation was based on just 7 actively erupting land volcanoes and three actively erupting ocean floor hydrothermal vents (seafloor hot geysers).
Utilizing gas emission data from this very limited number of volcanic features, Gerlach estimated that the volume of natural volcanic CO2 emissions is 100 to 150 times less than the volume of man-made CO2 emissions from the burning of fossil fuels and therefore of no consequence.
To put this calculation process into perspective, the Earth is home to 1,500 land volcanoes and 900,000 seafloor volcanoes/hydrothermal vents.
By sampling just an extremely small percent of these volcanic features it is impossible to imagine that the calculation is correct.
Especially knowing that volcanic activity varies greatly from area to area, volcano to volcano, and through time. Utilizing just 0.001 percent (10/901,500) of Earth’s volcanic features to calculate volcanic CO2 emissions does not inspire confidence in the resulting value.
Non-Erupting Volcanoes Can Emit Massive Amounts of CO2 into Earth’s Atmosphere
Recent geological research by the University of Leeds and others proves that non-erupting volcanoes can emit massive amounts of CO2 into Earth’s atmosphere and oceans. The Gerlach calculation and all follow-up calculations utilized volcanic CO2 rates from actively erupting volcanoes.
Lost in the numerous recent media articles concerning the argument of when, or if Iceland’s Katla Volcano will erupt is the discovery that this non-erupting subglacial volcano is currently emitting staggering amounts of CO2 into Earth’s atmosphere!
