Oxygen gas began to appear on the earth surface about 2 billion years ago by photosynthesis. Carbon Dioxide was converted into carbohydrates in the process. Where did these carbohydrates go? If they were converted into coal, oil, and natural gas over millions of years, then by releasing them back to the atmosphere in a couple of hundred years by combustion, we are definitely changing the atmospheric composition. This will definitely change the climate. This argument for climate change seems easy to understand and bulletproof. However, I have not heard this argument mentioned by the media. Why?
