“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.
“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 upon 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.
