It looks like you've just discovered one little part of what the climatologists knew decades ago, but because of your irrational belief that CO2 does not cause warming, you've completely misunderstood its implications.
You've found one half of a feedback mechanism. Warming (originally from a change in the solar radiation we receive) causes more CO2 to be released, which causes more warming, which causes more CO2 to be released, which causes more warming...
Eventually another change in the amount of solar radiation the planet receives results in cooling and a decrease in CO2, which results in more cooling and a further decrease in CO2 levels, resulting in more cooling.
And because of that, atmospheric CO2 levels have fluctuated with minima between 180 and 200ppm, and maxima between 280 and 300ppm.
And because of human activity, we're currently at 420ppm.
Despite a small decline in the amount of solar radiation we're receiving, the planet is still getting warmer.
