The real issue is what can our blood absorb. The surface atmospheric pressure is about 14.7 PSI. The oxygen partial pressure is about 3.1 PSI. Our blood can only absorb O2 in a limited range of partial pressure. Too high you get whats called oxygen toxicity and you will die. To little and you get oxygen starvation.
That is why when you SCUBA dive, beyond a certain depth you have to used mixed gases, not just straight air, in SCUBA tanks because the air pressure from the regulator must increase to match the water pressure as you descend in depth. A mix like HeliOx for deep diving will reduce the O2 partial pressure that has increased due to depth to keep it near the 3.1 PSI range.
Likewise, the US space program used to use 10 PSI air, with a higher percentage of O2, again to try to keep the partial pressure of O2 the same. Not sure what mix the space program uses today. The Russians always used 14.7 PSI air. I think when we started doing joint missions, we also went to straight 14.7 PSI air.
The increase in the HEAT of the planet (in that layer between the ground and about 50feet high) is most assuredly a product of mankind. But it nothing to do with CO2.
What man 'made' that affects the rather limited area we 'measure' is HEAT. We add HEAT to the atmosphere and the ground layer.
In the winter, we use various sources of energy to produce HEAT for houses and buildings. We have to keep 'adding' it because it escapes to the outside.
In the summer we use various sources of energy to 'cool' the air INSIDE buildings and houses. It does this primarily by 'pumping' the HEAT back ... outside.
So.... we do contribute to 'localized' warming which affects the areas where the most heat is produced. Most of the planet is covered by oceans, which are not affected by our 'contribution'. Therefore the claim that what we do has a 'global' effect is incorrect. We Heat the environment around us on land mass (29% of surface), and we only really heat up about40% of the land mass. 40% of 29% would be around 12%.
Even with all the HEAT we add (non stop , 24/7) , the temperature in any given area can drop 10-20 degrees in a matter of seconds merely due to the movement of a cloud between us and the SUN.
We produce heat nonstop on about 12% of the Earth's surface and it only makes the areas that produce heat, hotter. Given that the heat rises and eventually dissipates , the overall 'global' effect is almost nil.
If the general public were given a truthful education, they would realize that ADDING HEAT to the equation is probably a BENEFIT to LIFE on EARTH.
Most things on the surface grow because of HEAT and LIGHT. As we EXPAND our use of the land, we have made it better. The MIDWEST used to be a dust bowl. Now it's the breadbasket of our nation.
The solution to the global alarmism is simple.
They can't solve the problem because they are dealing with the wrong problem.
The CO2 has nothing to do with the HEAT, and the HEAT isn't the problem.
The truth is that foreign nations pollute their 'air' unabashedly and refuse to invest the money (like we did) to filter out pollutants. The 'globalists' was US to pay for fixing THAT problem. They certainly aren't going to use 'their' money to do it.

All kinds of macro and micro effects to be sure.
We get a not quite constant influx of heat from the sun, and the Earth radiates heat to space. The hotter we are, the more we will radiate.
In a closed system, mass and energy remain constant, but we’re not quite a closed system.
Agree about localized changes and agree that the majority of life as we know it does better in a warm climate than in a cold climate.
Global Warmers want to have us think that man made CO2 will cause warming, ignoring a great many things including plants usage of CO2 as food, and the oceans action of absorbing excess CO2 (all about partial pressures of gases and absorptivity of liquids.)
Whats it all mean? It doesn’t hurt to plant a tree. :)
How do you think all those giant Dino’s got fed....
Co2 levels were up to 10 TIMES as high as today!!!!!
