Earth's temperature is a chemical process system. Review of control system engineering of Earth's thermostat with anthropogenic CO2 in 1997 proved it will never work because it is an unmeasurable, unobservable and uncontrollable system. CO2 does not affect temperature; temperature affects CO2. There are no greenhouse gases in physics. CO2 is not a pollutant; it is green plant food. Global warming stabilized since 1998.

is not a pollutant; it is harmless green plant food. CO2
is the inert result of complete oxidation. There are only two CO2
gas phase reactions, both are endothermic: arc welding and photosynthesis (CO2
+ H2O + sunlight = sugars + O2
, catalyzed by chlorophyll). US Navy submarines limit CO2
to < 8,000 ppmv only because at that level it displaces O2
• Halting all combustion of hydrocarbons (oil, gas, coal and wood) by man will not measurably affect atmospheric CO2
content, now 380 ppm. A simple material balance shows man generates 30 billion tons/year (this is neither a big nor a small number, it is just a number) while plants consume 7 trillion tons/year (this is neither a big nor a small number, it is just a number). Forest fires, rotting flora and volcanoes input most of the CO2
to the atmosphere. Total input or output is >7. The ratio is 0.03/7 = 0.0043 (this is a small ratio). Cutting the 30 in half to 15 will drop CO2
by 100 ppm after 70 years.
does not affect temperature; rather temperature affects CO2
. Data for the past 400,000 years
, reported by Al Gore, An Inconvenient Truth
in 2005, shows they cycle together but CO2 lags temperature
by about 800 years. Solubility of CO2
in water, oceans, beer and champagne decreases with temperature so solar warming of the ocean releases dissolved CO2
and cooling reabsorbs it. Solar radiation drives Earth's temperature
has nothing to do with it.
