CO2 is not a problem on earth, and it will never be a problem. It is 100% natural plant food. It makes the planet greener and provides food. Satellite studies show that the earth is becoming greener as the CO2 concentration in air is increasing. Many peer reviewed science studies show that increasing CO2 increases the volume of plants. Photosynthetic incorporation of CO2 from the atmosphere into plants is the ONLY significant mechanism of building carbon based life.
It is impossible for CO2 to increase to a concentration that becomes dangerous. Henry’s Law defines the relative concentration of any gas in air versus any gas dissolved in water. CO2 is highly soluble in water. According to Henry’s Law, the concentration of CO2 in air will never exceed 1 part versus 50 parts in water. Most of Earth is covered with oceans. Dissolved in these oceans are an abundance of minerals such as calcium. In the top 200 meters of ocean water alone, there is more than enough calcium to combine with all of the carbon on earth and convert it to calcium carbonate, which will precipitate out and fall to the bottom of the oceans as limestone. This has been happening for millions of years. The layers of limestone and marble are the geological record of this. Enormous heat is required to reconvert this limestone or marble into CO2 and calcium. The heat of a volcano is required. All of this has been known for many years. It is available in textbooks for ocean and atmospheric chemistry. This information is usually ignored by so-called climate scientists. Become conversant in Henry’s Law and Earth’s natural carbon cycle and you will know with certainty that human caused global warming is a scam.
