I was once a believer in the CO2 global warming theory.  That was until I actually examined the science, and discovered not only that it was theoretically absurd, in that it contravenes the First Law of Thermodynamics, but many of the cited results, which a technically ignorant press broadcasts far and wide, are downright fake.  By fiddling the measurements to match the increase in CO2 concentration, the charlatans persuade the unwary that CO2 controls the Earth's temperature.  That is utter nonsense.
