The reason humans can't impact the CLIMATE with CO2 is because our release of CO2 is miniscule in comparison to the CO2 absorbed and released by for example the oceans due to changes in the sea temperature due to the Sun.
Complete Bullshit. That is the natural carbon circulation. Taking carbon out of the ground and transport it into the atmosphere and the ocean means to enrich the atmosphere and the ocean with additional carbon. Every child understands it.
Even a child can understand that Santa came down the chimney, ate the cookies, drank the milk, and dropped off a load of presents.
CO2 is a trace gas in our atmosphere. Currently around 400 ppmv or 0.04%.
Combustion of fossil fuels accounts for about 5% or so of the total release of CO2 into the atmosphere per year. Natural processes release and absorb many times that per year.
Here's a concept that 'even a child can understand.'
- He wasn't driving drunk, he just had a trace of blood alcohol; 800 ppm (0.08%) is the limit in all 50 US states, and limits are lower in most other countries).
- Don't worry about your iron deficiency, iron is only 4.4 ppm of your body's atoms (Sterner and Eiser, 2002).
- Ireland isn't important; it's only 660 ppm (0.066%) of the world population.
- That ibuprofen pill can't do you any good; it's only 3 ppm of your body weight (200 mg in 60 kg person).
- The Earth is insignificant, it's only 3 ppm of the mass of the solar system.
- Your children can drink that water, it only contains a trace of arsenic (0.01 ppm is the WHO and US EPA limit).
- Ozone is only a trace gas: 0.1 ppm
