Advancing Freedom With Data: Debunking Catastrophic Greenhouse Warming
CO2’s greenhouse effect is the result of its interaction with the infrared of the electromagnetic spectrum, which is now largely saturated at today’s CO2 concentration of about 420 parts per million (ppm), say William Happer and Richard Lindzen. With so little unaffected infrared radiation left to interact with CO2 molecules, adding more of the gas is having a trivial effect and will produce even less warming in the future.
