From the paper: “It has long been accepted that the ‘greenhouse effect’, where the atmosphere readily transmits short wavelength incoming solar radiation but selectively absorbs long wavelength outgoing radiation emitted by the earth, is responsible for warming the earth from the 255°K effective earth temperature, without atmospheric warming, to the current average temperature of 288°K.” Of the 33°K warming, the authors conclude that water vapor (H2O) is responsible for 29.4°K , with carbon dioxide (CO2) contributing 3.3°K, and methane (CH4) and nitrous oxide (N2O) combined just 0.3°K. This result, the authors say, strongly suggests that increasing levels of CO2 will not lead to significant changes in Earth’s temperature and that increases in CH4 and N2O will have a very little discernable impact. A four-fold increase in CO2 concentrations to 1,600 ppm will increase temperatures by 1°C and it would take around 800 hundred years to reach that point at the current rate of CO2 level increases.
The authors conclude:
“There is, and never can be, a tipping point. As the concentrations of greenhouse gases increase, the temperature sensitivity to those increases becomes smaller and smaller. The Earth’s atmosphere is a near perfect example of a stable system.”
“The atmosphere, mainly due to the beneficial characteristics and impact of H2O absorption spectra, proves to be a highly stable moderator of global temperatures. There is no impending climate emergency and CO2 is not the control parameter of global temperatures, that accolade falls to H2O. CO2 is simply the supporter of life on this planet as a result of the miracle of photosynthesis.”
For some background on the “greenhouse effect” see my blog post:
Bottom line: This study, and other studies, show that carbon dioxide has an insignificant effect on global temperature. Therefore all efforts to reduce carbon dioxide emissions and achieve “net-zero” will not stop climate change and are just very expensive and futile exercises.
