CO2

Sir: Will you or a politician please explain to the people the thermodynamics of how .038% of CO2 can change the earth’s climate? It has never done so in the past; an increase or decrease of CO2 has never led nor followed temperature changes. Until we can do this we are gullibly following an unprovable theory wasting billions better used for health, education and dam building to irrigate the inland for future generations.
