Alternative Scientific Views Now Come to the Fore

But since Hansen’s watershed moment in 1988 the science has moved on and many independent scientists, not on the government grant gravy train, have cast their eyes over the numbers for carbon dioxide (CO2), the prime bogeyman of climate alarmism.

From physical measurement of the Earth’s radiative spectrum impartial eyes saw that the 14.77 micron band of the Earth’s thermal radiation accessed by CO2, is so close to saturation that it is a physical impossibility for any increase in that trace gas to have anywhere near the effect claimed.
Analysts then looked back at the natural warming since the 1830’s that ushered in the end of the Little Ice Age, a time 100 years before any scientist claims humans had impact on the climate. They say natural warming in the order of 0.5°Centigrade per century. We can calculate this to show that the maximum possible effect from CO2 increases is just 0.1°C per century of the claimed 0.6°C per century of the observed temperature increase.
Hansen and his self-serving followers in climatology conveniently chose to ignore such inconvenient truths. Kalmanovich seethes,
“They falsely attributed the effect of CO2 to the full 0.6°C and incorporated a range of wavelengths from 7 to 14 microns when CO2 only has an effect over a range from 13.5 to 17microns and the wavelength band is at least 80 percent saturated. Though never stated explicitly this formed the basis for the CO2 forcing parameter which Hansen used in his earlier climate models and is still used by the IPCC today with the basic formula of 5.35ln(2) = 3.71watts/m2 for a doubling of CO2.”
Like other independent scientists Kalmanovich saw that the fuss all stems from a 1981 paper by Hansen that was peer reviewed and published in SCIENCE magazine. Here’s where Hansen’s alarmist and skewed climate models captivated scientific literature on the matter. It is by repeated reference to Hansen’s original paper and his 1988 modification of it that the current climate change issue was premised.
In REAL Science Correlation Does not prove Causation
All the other evidence is either of warming or misrepresentations of the greenhouse effect but never of an actual relationship between the two other than a stated correlation stating that CO2 increased and global temperature increased and therefore CO2 caused the global temperature increase.
Kalmanovich’s findings have been corroborated by a group of independent scientists calling themselves the ‘Slayers’who claim to have refuted the greenhouse gas effect.
They agree that correlation between temperatures and CO2 is easily refuted and they cite the same numbers used by the IPCC in the 2001 report.
That report shows cyclic warming and cooling trends that are completely out of step with CO2 emissions as explained by Kalmanovich, “it shows rapid warming from 1910 to 1942 with only a trivial 14 per cent increase in CO2 emissions. That is followed by 33 years of a global cooling trend with a 500 percent increase in CO2 emissions from 1942 to 1975.”
