CO2 is a "trace gas" in air, insignificant by definition. It absorbs 1/7th as much IR, heat energy, from sunlight as water vapor which has 188 times as many molecules capturing 1200 times as much heat making 99.9% of all "global warming." CO2 does only 0.1% of it. For this we should destroy our economy? The Medieval Warming from 800 AD to 1300 AD that Micheal Mann erased to make his "hockey stick" was several degrees warmer than anything "global warmers" fear. It was the longest recorded time, 500 years, of peace with great abundance for all. The Vostock Ice Core data analysis show CO2 increases follow temperature increases by 800 years 19 times in 450,000 years. That makes temperature change cause and CO2 change effect; not the other way around. This alone refutes the anthropogenic global warming concept. Carbon combustion generates 80% of our energy. Control and taxing of carbon would give the elected ruling class more power and money than anything since the Magna Carta of 1215 AD. Most scientists and science educators work for tax supported institutions eager to help government raise more money for them. And, they love being seen as "saving the planet."
