Professor Happer discusses CO2 and the Bad Press
CO2 is a greenhouse gas, just not a strong one. Professor Happer discusses why the impact of CO2 is small on the earth surface temperature. The effect of CO2 saturates as the amount of CO2 increases even to the 2X amount, such that the change in temperature is small. It is not likely to see the impact of 2x CO2 above 1 to 1.5 C. Exaggeration expands this impact greatly using feedback to achieve the artificial runaway warming. This is not good science.
False popular media want to compare the future earth to Venus which has an atmosphere of all CO2, which has atmospheric pressure 100x that of earth. It also is much closer to the sun and therefore sees more of the sun’s energy. It should be noted that Mars atmosphere is also largely composed of CO2 (95%) but Mars is cold because of its relative distance from the Sun.
Having small amounts of warming is good for the earth and nature.
The political efforts to make the warming from CO2 increases dangerous are intended for obvious reasons to drive energy policies, and it is not scientific or good science.
