Didn’t the famous pothead, Carl Sagan start the “CO2 is causing global warming” hysteria? He also said the first Gulf War would cause a nuclear winter because of the oil well fires.
Sagan may have popularized the idea, but the Swedish scientist Arrhenius is evidently the first to propose that if the CO2 in the atmosphere increases geometrically, earth's temperature will increase arithmetically.
CO2 has been considered the driving temperature force by most of the modern day warmists. But earth and its climate are orders of magnitude more complicated than foreseen by Arrhenius and by our modern warmists.
Gee, we exhale CO2 with every breath, the CO2 is absorbed by plants that exhale oxygen.
Somebody has really provided for mankind insofar as this planet is concerned.
