The ‘climate crisis’ is entirely generated by media and climate activists!

Alright, here’s the deal: CO2's ability to absorb heat (via infrared light from the earth’s surface) maxes out at a certain point, like filling up a sponge. This has been known for a while, thanks to experiments by physicist Heinrich Hug and others. Hug showed decades ago that at a CO2 level of 257ppm, the absorption of infrared light at 15 microns—where CO2 is most active—hits saturation in under 10 meters of air. Also, widening the absorption band and doubling CO2 to 514ppm only bumped absorption by 0.17%, which is almost nothing.

That means after a certain point, adding more CO2 to the atmosphere doesn’t keep increasing heat absorption. Basically, it’s already doing all the absorbing it can, so any extra CO2 doesn’t have much effect. Saturation also means that CO2 does not pass on the absorbed infrared light at 15 microns to the upper atmosphere to be reabsorbed again by CO2 and cause further heating with more CO2….. It is saturated.

The key science behind this is Beer's Law, which says absorption depends on the concentration of an absorber and the distance the light travels through it. I learned this in college and applied it for 45 years in my career. The IPCC and others talk about CO2 increasing warming by spreading out into nearby wavelengths (14-16 microns), but this effect is tiny, see above, and they often ignore the saturation issue altogether.

The saturation idea, mostly ignored by climate modelers, really punches a hole in the argument that more CO2 from burning fossil fuel keeps cranking up the heat.
Can we get back to the basics on this before building climate models, please?

So now we know there is no crisis what are we going to do to stop the net zero suicide.
