Global Warming and Climate Change} condensed 24 post's and one main paper
Cliff note's; of the 24 post's and main paper! 4.5 billion years ago there was no life on the newly formed planet, the atmosphere of the planet was almost all carbon dioxide, a small amount of nitrogen, a little hydrogen, and some sulfuric acid. the atmosphere was also much denser, how much that would be a guess, perhaps on the order of 10 times as much. Once some type of life began that used the carbon dioxide-sun-water to begin photosynthesis, then carbon sequestration also started.So from the first life on the planet to now, carbon has been removed from the cycle of life, on a much larger scale then has been returned by volcanic action. In this same time frame, the sun's energy has been increasing by around 1% every100 million years. this extra energy would have offset the lost of the green house gas carbon dioxide, along with the much larger cloud cover, then we now have, that would have helped regulate surface temperature's. Whenever carbon dioxide and other greenhouse gas's became too low for the weaker sun then we enjoy now, a ice age would start! Some of these were many million's of years long. Around 2.4 billion years ago, the conversion of carbon dioxide to carbon and oxygen, started a whole new phase of life, and a huge die off of the existing life, due to oxygen being a poison to some of that old type of life. The new type of life, did not use photosynthesis, to get it's energy but used oxygen to breathe, and ate the plant life to get the carbon it needed to survive. So it could be said that this new life was just a parasite, on the earlier life form, ( as we are to this day, so no different then any other type of life that does not use photosynthesis to survive. ) Carbon dioxide in the atmosphere, would normally be replaced by, ocean bound carbon. This is the reverse of what is happening today, because of man's introduction of carbon dioxide into the atmosphere by the burning of fossil fuels.
