Carbon dioxide is a linear molecule. It has three resonating structures: a double bond and two mirror images of single-triple bond. The latter is shortened by about 0.06 Å while the accepted distance for the double bond is 1.16 Å. At s.t.p. conditions of 273.15K and 760.0 mmHg its density is 1.977 g/dm³; m.p. -56.6°C; b.p. -78.5 °C. It is a colorless odorless gas, soluble in water, ethanol, and acetone. As a component of the atmosphere it is both consumed by plants during photosynthesis but respired by all living things. Moreover it is produced abundantly by wholesale combustion. Since CO2 is 50% heavier than air there is no compelling reason why it should rise above the other gases in the atmosphere except when in a state of high kinetic energy. Therefore it couldn’t possibly be responsible for greenhouse effect at high altitude. However, at low altitude it could possibly be the only source of global warming. If the greenhouse effect is a low altitude affect attributable to excess CO2 over the other greenhouse gases: methane, water vapors, nitrogen oxides, ozone, and chlorofluorocarbons then it is solvable by human re-intervention in reducing further artificial emission of greenhouse gases. The thickness of the biosphere is about 12 miles giving a control volume of 3 billions cubic miles. This includes parts of the troposphere and the hydrosphere. The solution is artificial or man-made photosynthesis. Time independence: [∂E(g)]²=[∂F(a)×∂r(a)]·[∂F(b)×∂r(b)] and Mass independence: ¶a(t)·¶r(t)=c² |
