Quadrupling Carbon Dioxide Would Cause Only 1.0°C Warming According to New Study

There is no climate crisis says a new study published in the International Journal of Atmospheric and Oceanic Sciences.

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.”

The Broken Greenhouse – Why CO2 Is a Minor Player in Global Climate

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.

  1. I’m not too concerned about CO2. In fact, I welcome it as someone in aggie. No CO2, no plants. Most fungus exchange plant based material (leave, branches, bark) for CO2. They need oxygen to survive, and repay with CO2.
    I wish I could find that study on old-growth forests. While it was done in the 70s, you’d probably enjoy it.
    In it, from Year 1 to 25, trees average more oxygen and take in CO2 than 25-50, which is verging on or at neutral use of CO2 and producing oxygen. From 50 years up, a forest produces more CO2 and methane than it does oxygen. By the time it’s a century old, it’s virtually uninhabitable for most wildlife and is only a fire hazard.
    As the ancestors knew, if you depend on hunting, get rid of the old-growth forest.
