As much as I'd like to turn this thread into a origins of life theories discussion, I will say the last 2 posts are logical fallacies. Are Carbon passports to curb human behavior the answer because man jeopardized life on earth by using hydrocarbon.
Two articles which present other sizeable CO2 release into the atmosphere.
Deep CO2 in the end-Triassic Central Atlantic Magmatic Province
https://www.nature.com/articles/s41467-020-15325-6"In fact, a single short-lived CAMP magmatic pulse (ca. 105 km3 erupted over 0.5 kyrs)21,22,23 may emit about 5 × 1016 mol CO2,
roughly the same total amount of projected anthropogenic emissions over the 21st century, according to the Representative Concentration Pathway 4.5"
So it reports that even one volcanic event can release as much co2 as humans the entire 21st century.
Unexpected large evasion fluxes of carbon dioxide from turbulent streams draining the world’s mountains
https://www.nature.com/articles/s41467-019-12905-zIf the earth is responsible for CO2 emissions that can act as a thermal influence, another article suggest earths mechanics can regulate temperature.
Earth's Climate Thermostat

In March of 2001 a significant paper by Richard Lindzen of MIT was published in the Bulletin of the American Meteorological Society which addresses the cloud-cover feedback mechanism.
Dr. Lindzen has been a long-time critic of the Intergovernmental Panel on Climate Change (IPCC) and a highly respected researcher in the atmospheric sciences.
His paper reports that clouds in the tropics respond to warmer sea-surface temperatures (SST) by permitting long-wave radiation to space to increase, causing greater cooling of the atmosphere.
This negative feedback mechanism would more than cancel all the positive feedbacks included in the more sensitive current climate models.
Dr. Lindzen calculated the average SST as a function of cloud cover and found a strong negative relationship.
His explanation for the negative relationship is that warmer SSTs lead to higher humidities and greater convective activity.
This greater convective activity is more efficient in creating rainfall, leaving less moisture to form cirrus anvils which prevent long-wave radiation from escaping to space.
Consequently, warmer SSTs lead to more rapid cooling of the atmosphere and stabilization of the earth's temperature. "
