Two scientists clearly show that more CO2 in the atmosphere can hardly have an impact on global temperatures. The attempts to further reduce CO2 emissions are therefore “completely pointless”.
The models used by the climate fanatics are not aware of any saturation effect, but are based on the premise that the equation “More CO2 = higher temperatures” goes on almost indefinitely. They also ignore the fact that the global climate is a complex interaction of different factors, in which solar activity, for example, also plays a certain role. In doing so, these fanatics also ignore the fact that the earth has seen significantly higher CO2 concentrations in the past and was colder than it is today.
A detailed paper on this topic was published two years ago by Princeton Professor Emeritus William Happer and Canadian physicist Professor William van Wijngaarden. The two renowned atmospheric researchers analyzed around 330,000 lines of the HITRAN spectrum in order to observe and calculate the ability of five greenhouse gases to emit heat. The molecular spectroscopic database HITRAN (an acronym for High Resolution Transmission) is a compilation of spectroscopic parameters used to simulate and analyze the transmission and emission of light in gaseous media, with a focus on planetary atmospheres.
As you can see from the graphic above, the so-called greenhouse gases make a difference in terms of heat being radiated back into space. The blue line shows what the atmosphere would be like without these gases, while the green line would be the result of “net zero” at the existing levels. The black line corresponds to a level of 400 ppmv CO2 (we are currently at around 420) and the red line an increase to 800 ppmv CO2 – i.e. a doubling. In a nutshell: Without greenhouse gases in general, the world would be an average of 33 degrees Celsius colder than today (so even in the tropics we would have frost), but even if the CO2 concentration were to be doubled to 800 ppmv, there would no longer be a significant difference. This means that we have already reached a saturation point in terms of greenhouse gases.
In his recent paper ‘Challenging “Net Zero” With Science’, Happer made it clear that the decreasing warming value of CO2 is logarithmic, with 88 percent of the possible warming already taking place. “This means our emissions from burning fossil fuels will have little impact on global warming from now on. We can emit as much CO2 as we want without causing warming. There is no threat of climate emergency at all,” he wrote.
German physics professor Dieter Schildknecht also noted that increasing the level of CO2 in the atmosphere beyond 300 ppm “cannot lead to appreciably greater absorption of radiation and consequently cannot affect the Earth’s climate”. He calculated that a doubling of CO2 leads to a warming of 0.5 degrees Celsius, since saturation is “close to 100 percent”. In doing so, he supports the calculations of Happer and van Wijngaarden, which are completely ignored by the climate fanatics.
