1.) IF we assume that CO2 is the root problem to Global Warming and Climate Change, THEN consider what would happen if atmospheric CO2 were, somehow, to be eliminated:
The process of Photosynthesis, defined chemically as follows:
6CO2 + 6H2O + (n)photons = C6H12O6 + 6CO2
would cease to generate carbohydrates, (C6H12O6), for most plants and the animals that eat the plants and eat the animals that eat the plants.
2.) To the best of my research, there has never been a cause and effect experiment that establishes that a change* in the concentration of CO2 has had a measurable effect on the temperature of the air.
*Note: at atmospheric concentrations of CO2 approximating maximum to minimum living conditions for most plants.
3.) All known published speculations on the effect of CO2 on temperature are based on the false assumption, as proven by # 2 above, that there is a measurable effect of the change in atmospheric concentration of CO2 on the temperature of the atmosphere.
It is Scientists such as Dr. Lennart Bengtsson who are willing to oppose the peer pressure of emotion-based politics, and stand, resolute, for what can be proven by fact-based Science.
Such men inspire other Scientists to continue the never ending search for Truth, regardless of the severity of peer-pressure inquisition at the time.
As we look to our own US Society, now in the watershed battle between the adherents of the original, empirical-based, US Constitution, and the proponents of emotion-based Socialism, let us pause now and then to refresh our courage by remembering the bravery of men such as true Scientist Dr. Lennart Bengtsson.
