Global warming does not exist and is not scientifically credible. The planet is cooled by radiation which goes around greenhouse gases, not through them. Cooling results in an equilibrium temperature which is independent of how heat gets into the atmosphere. It means greenhouse gases have no influence upon the temperature of the planet.

The amount of carbon dioxide in the atmosphere is so low that all biology is on the verge of becoming extinct due to a shortage of CO2 which is needed for photosynthesis. There was twenty times as much CO2 in the atmosphere when modern photosynthesis evolved. Oceans continuously absorb CO2 and convert it into calcium carbonate and limestone. The calcium never runs out, and the pH of the oceans never drops below 8.1 for this reason. It's the pH which calcium carbonate buffers at. If not, why hasn't four billion years been long enough to get there?

The Erroneous Assumption

The primary error is the assumption that global temperature is determined by how the planet is heated rather than cooled. Not so. The heat is everything that the sun adds to the earth. How the heat is moved around is irrelevant. A jar of pickles will absorb radiation, but it doesn't heat the planet.

If the rate of heat leaving were the "delicate balance" which is claimed, nothing about it would be stable. To think life lucked out at 180 or 280 parts per million CO2 is stupidity. The temperature changes by at least 5°C between each ice age, which occurs every 100 thousand years.

All major forces in nature equilibrate. They change until they can't change anymore, which is equilibrium.
