A viewer asks: “Creator, is there a simple explanation why the current CO2 concentration, 420-430 ppm, is much too low to have a practical influence on temperature?”

Questions about the environment and the impact of CO2 are made controversial in order to support a propaganda campaign to indict fossil fuel use as harming the environment, leading to global climate change that is deleterious and even potentially fatal to life on the Earth. This is all a concoction to manipulate and cause fear and a self-inflicted impairment on human welfare by ruling out use of abundant natural resources readily available to supply power and energy for the needs of modern civilization, inexpensively and conveniently. This is entirely sinister. You are asking us to prove a negative. The burden is on the advocates who say CO2 at current levels is dangerous and that higher concentrations will lead to calamity. This is only done through subterfuge, misrepresentation of facts, and exaggerated fear mongering. In truth, CO2 which is feared to lead to a warming of the planet through a greenhouse effect, has far less potential than water vapor in trapping the sun's heat and thus contribute to global warming. We cannot lead with specific information of this kind when it is available if you consult reliable scientific sources. Your channel will be giving a recent compendium of knowledge about climate issues that is a good scientific summary and that will be related in his next webinar.
