Sid: Post # 1930
"The hypothesis is that even though the Sun is 100 times larger than the Earth, we can somehow modulate the climate by reducing or increasing the amount of CO2 in the atmosphere as if it is a thermostat button (CO2 only forms .04 percent of the atmosphere.). The problem with this hypothesis is that it can neither be proven nor disproven that this tiny percentage of the atmosphere (.04 percent) is a thermostat button."
[A side issue, though an important one: "One easy hypothesis to prove or disprove is that if we go below .02 percent, all vegetation on Earth dies, including all humans, as a result."
Anthropogenic Negative Climate Change Response
Statistics Lie
I assume Sid is correct that given the Earth's atmosphere from soil to space, the AVERAGE proportion of CO2 in the atmosphere is 4%.
So what.........?
Averages destroy the fact of concentrations existing in reality, as opposed to pure mathematics creating a totally uniform model.
So what is in fact happening is not THROUGHOUT the whole atmosphere! There is a problem due to concentration of CO2 (And other greenhouse gases) at a particular level of Earth's atmosphere.
What man is doing, is, approximately half-way up the atmosphere, creating a concentration of certain gases. And so half-way up the atmosphere, encircling the whole earth, is the start of the "egg shell" - this is a belt or canopy that is being generated that is "different" from the rest of the diffuse atmosphere. This shell is transparent but of a higher density than the atmosphere below it and above it, re the particular gases of concern.
It is an agglomeration of gases (Methane, CO2, etc.) which allow through the solar energy of the sun. This solar energy heats the atmosphere and Earth's soil. In the past, the heat energy has then been reflected back into the vacuum of space. So there was relative stability of Earth's temperature re solar energy........we did have different long ages of rising and falling temperature, but this was due to other factors.
What is new, since the dawn of human industrialization (Around 1850), is the introduction of, and greater local intensification of, the "egg shell", the greenhouse gas canopy.
Consequence
Now what is happening is that the Earth's reflected heat is escaping LESS than it did into space. Very slowly and incrementally, the Earth/Atmosphere within the "egg shell/Greenhouse Gas Canopy" experienced rising heat/temperature, that was being TRAPPED!!
Conclusion
1. Man must pinpoint his human activities that are generating the most greenhouse gases into the atmosphere.
2. He must, at some cost, but without total destruction of society, cease those activities which are producing these greenhouse gases.
3. Science (Mainstream) tells us that Earth has a "Tipping Point" with respect to the combination of factors that make Earth's Environment hospitable to man (And most other Earthly life). If man causes "CHANGE" to some of these factors, there comes a point at which Nature can no longer RETURN to its former state. In other words, a new PERMANENT Environment will be created.
4. Should man succeed in creating such a new, permanent Earthly environment, then man is on a slow suicidal curve towards extinction. Mainstream science says that humans (And much other life) will find that the new environment is totally HOSTILE to their continued existence on this planet.
