The definition of the Seuss Effect is as follows:
“The Suess effect is a change in the ratio of the atmospheric concentrations of heavy isotopes of carbon (13 C and 14 C) by the admixture of large amounts of fossil-fuel derived CO 2, which is depleted in 13 CO 2 and contains no 14 CO 2.”
Keeling’s isotopic ratio argument and Mann’s tree ring data continue to be riddled with holes, especially by observation of the Carbon-14 emitted from deep ocean hydrothermal vents as well as recent work on tree rings at the University of Arizona.
Quoting from the linked paper from the Scripps Institute, re: hydrothermal vents:
“We present evidence here, based on 14C activities and 13C/12C ratios, that the principal source of dietary carbon for mussels and tubeworms is derived from the dissolved inorganic carbon (DIOC) in the vent effluent”.

What may even be more important is the estimated 40,000 giga-tonnes of CO2 dissolved in the ocean waters as well as the estimated one (1) million submarine volcanoes contributing CO2 to the deep abyssal waters.
The very words expressed by Charles Keeling in his 1979 paper citing the “Seuss Effect” provide his own admission that sufficient information was available regarding Carbon isotopes in the ocean waters. Quoting from Keeling:
“The oceanic data are seen to be too meager as yet to help settle the question of biospheric response to man’s activities.”
New learnings of Carbon-14 dating in tree rings are also underway at the University of Arizona. Quoting from linked article:
“Radiocarbon dating, as of now, dates samples to within a few decades using a calibration curve made up of groups of ten tree rings plotted as series of single points on a graph. The points represent an average amount of radiocarbon present in those rings. This doesn’t account for spikes in the data—individual rings with unusually high or low amounts of carbon-14. These spikes in radiocarbon can come from a number of short term events, like solar flares, volcanic eruptions, and changes in oceanic circulation. By lumping ten years’ worth of radiocarbon data into a single data point, spikes in radiocarbon may inadvertently skew the curve making dates less accurate.”

That is to say, the radioactive isotopes of C-13 and C-14 are variable and they also come from within the planet. They are not just provided in a constant manner from spallation of Nitrogen in the upper atmosphere.
This finding is further supports the existence of Herndon’s GeoReactor as the variable source of heat and CO2 emanating from within the planet. Carbon 14 is also generated from Fission.
