“How much did the planet cool when Mao killed 30 million Chinese after the Cultural Revolution? Or after Stalin caused 6-8 million to die in the Ukranian famine?”
Last time I read about that it was 40 million for Mao and 20 million Ukranians.
What, are they revising the numbers downward bit by bit?
It depends largely on who you cite as a source, and what time frame one uses. I was only making a point about the insanity of assuming that human beings can have any substantial control over CO2 amounts in the atmosphere, 97% of which is naturally-occurring (e.g. - evaporative water vapor) and which only constitutes 0.38% of the Earth’s atmosphere to begin with.
