Last" Doesn't Always Mean "Previous - 8

Atmospheric gas

Earth's lower atmosphere (dry air) is primarily composed of Nitrogen (78.08%) and Oxygen (20.95%), which together make up about 99% of its volume. The remaining 1% consists of Argon (0.93%), Carbon Dioxide (approx. 0.04%), and trace amounts of neon, helium, methane, and other gases. Water vapor content is highly variable, ranging from near 0% to 4%.

Key Components of Earth's Atmosphere (Dry Air) Nitrogen (N2): 78.08%, Oxygen (O2): 20.95%, Argon (Ar): 0.93%, and Carbon Dioxide (CO2) (approx 0.042%) (variable but increasing).

Trace Gases: Neon (Ne), Helium (He), Methane (CH4), Krypton (Kr), Hydrogen (H2) fill in to 100%.

Key Details Variable Gases: While nitrogen and oxygen are constant, water vapor (H2), carbon dioxide (CO2), and methane (CH4) concentrations fluctuate based on location and time.

What impact do these changes in gas percentages have?

In the previous post we show graphs concerning changes in temperature and humid air pressure/density (Last" Doesn't Always Mean "Previous - 7).

The graphs below show the impact on layers and zones in terms of "chemical potential" when those changes in t_si/p_si take place.

But what happens when the percents change, but still add up to 100%?

If Nitrogen (N2): 78.08% drops to 75% and the 3.08% is distributed in the other gases, what impact does that have on temperature, pressure, density and cheical potential?

I will explore that in the next episode, but in the meantime let's ponder the event that scientists "got wrong", i.e., when the 2024 heat increase caught them by surprise ("Last" Doesn't Always Mean "Previous" - 4).

And let's ponder why Dr. James Hansen says it was the removal of "aerosols" from the atmosphere (EPA regs changed concerning emissions by "container ships",  etc; and let's consider the hypothesis of "saturation" (The Saturation Chronicles, 2, 3, 4, 5, 6 , 7, 8, 9, 10, 11, 12).

Stay tuned if you dare.
