[[The generation of carbon dioxide in the atmosphere by the burning of hydrocarbon fuels (NOT “fossil fuels”) by all the activities of mankind is negligible, ]]

Roughly 0.00136% of the atmosphere (Note, thismis strictly co2 by man, not all greenhouse gases, which amounts approx .04% of atmosphere)

Man’s co2 in no way shape or form can possibly be responsible for warming. There just is nowhere near enough to blanket the earth in a thick enough blanket to stop heat from escaping.

Take a piece of legal document paper, and place a bb on it. That is how little our co2 takes up

Or to be more precise, put 4 5 gallon pails of water in an Olympic sized pool. That is 0.0136% of the pool. (Someone was kind enough to figure that out for me)

If we put 4 five gallon pails of 100 degree water into a pool that size, of water that is 90 degrees, does it cause “catastrophic warming”? Nope- doesn’t raise the pool temp,one bit, because there is nowhere near enough 100 degree water. The 100 degree water quickly reaches equilibrium because it is overwhelmed by the volume,of colder 90 degree water.

Same thing with pur planeT. Nowhere near enough co2 to cause warming.

The rise from about 280 ppm to 420 ppm is mainly manmade. Some of that rise would have occurred due to natural warming over past centuries. The ocean warming releases CO2 but it's a fairly small amount. Looking at ice cores CO2 lags temperature: https://realclimatescience.com/2019/04/does-co2-lead-or-lag-temperature/. First the temperature starts going up, then about 800 years later the CO2 starts going up. But looking at the amounts, the CO2 goes up about 10 ppm for each 1C of warming.

Natural warming over the past 500 or more years has been about 1-2 C. That means we should have seen about 10-20 ppm of CO2 rise, from 280 to about 300 ppm. Instead it's gone to 420 and rises about 2-3 ppm per year. The main explanation for the 2-3 ppm rise per year is fossil fuel. Another explanation is loss of plant life including ocean plant life. The best explanation is that it is mostly fossil plus some past deforestation.
