In his recent book, Rex J. Fleming asserts that "CO2 has no impact on climate change", or, as he summarizes on his website:
There are now over a dozen books available on Amazon.com that point out the various fallacies of the CO2 climate theory – but none of these have zeroed in on the heart of the issue – the failure of the Schwarzschild radiation integrations to maintain the CO2 longwave radiation intensity achieved in the surface warming by H2O and CO2. The resultant Planck radiation intensity is severely depleted in the upper atmosphere. The result is the CO2 molecules merely pass their remaining small residual heat to space un-impeded. CO2 has no impact on climate change.
This claim seems to contradict some basic physics.
Is Fleming correct that the "failure of the Schwarzschild radiation integrations to maintain the CO2 longwave radiation intensity" means that "CO2 has no impact on climate change"?
