Fossil fuels use in industry's and automobile's appears as one of the chief reason for this degrading of climate, globally. Its ill's can be briefed as per following discussions;
Fossil fuels get converted into heat,GHG byproduct & causing increase of GHG within fixed air volume V,so air density(d)increased;
Air Heat Q=mc∆T
Q=heat(Joules),m=Air mass (kg),c=specific heat(J/kg∙K)
m=Vd; Q=Vdc∆T
Q ∝ d
[Vc∆T=constant
∆T=Sunrays Temp]
#Q increasing with d
It is obvious that since many year's, the production of fossil fuels combustion by-products, say GHG is increasing continuously and contributing increase in the density of air within fixed volume of the atmosphere. As per simple above discussion, ∆T= incident sunrays temperature is constant, but density 'd' is increasing and contributing to the increase of Heat Q in the atmosphere.
Yes you are right the way you have explained by using the heat equation. However, the atmospheric temperatures is increased globally to the variable extent spatially. The increase in not contributed by the sun rays falling on the surface elbeit by the outgoing long way radiation and causing the heat building up by green house effect. Hence global warming is coz of climate degradation.......
At first global warming sounded like a good idea, But starting in the 1960s, scientists recognized long-range problems, concentrating at first on sea-level rise and a threat to food supplies. It was difficult to make solid predictions given the complexity of the global system, the differences from one region to another, and the ways human society itself might try to adapt to the changes. But by the start of the 21st century, it was clear that climate change would bring serious harm to most regions. Indeed many kinds of damage were beginning to appear. At first, the changes were apparent only in global statistics, but in the 2020s scientists began to show how global warming made particular heatwaves, storms, and other disasters more likely or worse.

The global warming is a real and serious matter, globally. Perhaps, now it seems as a long term issue, which needs to be vibrant frequently. Different individuals would've different feelings/solutions to this problem. I am thankful to some of RS colleagues for sharing there's view's, regarding. And looking to have more sharings, regarding in coming days.
Hi Raj,
As you know theory is nice, but it always has to be validated by measurements or experiments to be valid and of use.
The boundary conditions you describe as being constant, is not.
- ∆T= due to incident sunrays temperature is constant -> .NOT. TRUE
Have a look at the measurements I performed at the surface of PV panels at 50.1°N; 5° E.
Code General purpose FOURIER model code.
Clearly surface temperature of PV panels is very variable for the site measurements. And this is due to cloudiness changing each minute of the day and hence so does incoming solar radiation.
Withe FOURIER model here above this has been modelled. Hence, your estimate of density change and consequently a change in air heat Q is not corroborated at all.
Can you comment on this?
Cheers,
Frank
