• I think the ozone doesn’t protect life on Earth, because ozone is like it is not there – it has a so much small presence – it cannot stop anything.

"The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer peaks at 8 to 15 parts per million of ozone,[1] while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9 to 22 mi) above Earth, although its thickness varies seasonally and geographically.[2]"


For comparison, the trace gas CO2 content in atmosphere is ~ 420 ppm ( ozone is 0,3 ppm, ozone layer peaks at 8 to 15 parts per million of ozone, 8 to 15 ppm ).

How this low concentration of ozone is possible to absorb anything? Because it is asserted - since ozone at 8 to 15 ppm does those absorption wonders, then CO2 at ~ 420 ppm should moreover perform absorption wonders!


  • “The ozone layer was discovered in 1913 by French physicists Charles Fabry and Henri Buisson. Measurements of the sun showed that the radiation sent out from its surface and reaching the ground on Earth is usually consistent with the spectrum of a black body with a temperature in the range of 5,500–6,000 K (5,230–5,730 °C), except that there was no radiation below a wavelength of about 310 nm at the ultraviolet end of the spectrum. It was deduced that the missing radiation was being absorbed by something in the atmosphere. Eventually the spectrum of the missing radiation was matched to only one known chemical, ozone.[3] ”

It was deduced, and it was a mistake, because sun doesn’t emit as a perfect black body. Because there was no radiation below a wavelength of about 310 nm at the ultraviolet end of the spectrum.
