the googled responses make claims, but do not provide thermodynamics to justify it. These are assertions without justification.
For example
https://news.climate.columbia.edu/2019/07/30/co2-drives-global-warming/
"CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has “windows” that allow some of the infrared energy to escape without being absorbed. In addition, water vapor is concentrated lower in the atmosphere, whereas CO2 mixes well all the way to about 50 kilometers up. The higher the greenhouse gas, the more effective it is at trapping heat from the Earth’s surface"
"The burning of fossil fuels affects the concentration of CO2 in the atmosphere. Before the industrial revolution, the amount of CO2 in the atmosphere was about 288 ppm. We have now reached about 414 ppm, so we are on the way to doubling the amount of CO2 in the atmosphere by the end of this century. Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts."
And again, think rationally. Where rising temperatures release C02 from the ocean. It is the tail wagging the dog.
The Sun may vary well go through cycles of variable heat output etc, and that may be the true variable. Yet because there is rising C02 trace levels, and absurdly at a trace level, it is falsely accused as the cause.
