What Humans Contribute to Atmospheric CO2: Comparison of Carbon Cycle Models with Observations
(www.sciencepublishinggroup.com)https://www.sciencepublishinggroup.com/journal/paperinfo?journalid=161&doi=10.11648/j.earth.20190803.13“anthropogenic emissions of 4.7 ppm/yr do not contribute more than 1.6% or 6 ppm to the atmospheric CO2”
“The CO2 concentration follows these (sea surface) temperature variations with a delay of 6 - 7 months “
Sea surface temperatures control CO2, not puny inconsequental humans.
