More evidence of a scam, where climate alarmism is concerned…
New York State is investigating Exxon for telling the truth about CO2 in 1976, but the big story is that NASA and NCAR have known since 1971 that CO2 is not dangerous – yet have lied to the public about this for over 30 years.
In 1971, the top climatologists at NCAR and NASA reported that a runaway greenhouse effect is not possible, because the CO2 absorption spectra is nearly saturated already.
This is exactly what NCAR’s current radiative transfer models show. Adding more CO2 has very little effect on downwelling longwave radiation.
But it is worse than it seems. Scientists have actually known for 115 years that CO2 is not dangerous.
Knut Ångström, asked an assistant to measure the passage of infrared radiation through a tube filled with carbon dioxide. The assistant (“Herr J. Koch,” otherwise unrecorded in history) put in rather less of the gas in total…
