Your assertion that “CO2 breathes up and down on this planet, just like everything else” is untrue.
Our industrial release of CO and C02 is constantly on the rise and the natural check on these gases, photosynthesis, is constantly on the decline with the destruction of forest.
I know of no other physical system in which an attribute or variable can be consistently increased without check and the sytem not be completely changed with out reverse or break down.
While our release of CO2 is definitely increasing, do you have a reference for the second part of your assertion that "photosynthesis, is constantly on the decline with the destruction of forest" ?
30-some years ago, when I looked into this, the biggest contributors to CO2 removal were oceanic: plankton photosynthesis, dissolution in water, calcium carbonate synthesis by various organisms, etc.
Also, it would appear that increasing agricultural yields would offset any forest declines, at least to some degree.
Actually, increases in temperature PRECEDE increases in CO2.
Also, the solution to disappearing forests is more industrial development. It is the poor countries where one find forests being devastated.
Our industrial release of CO and C02 is constantly on the rise and the natural check on these gases, photosynthesis, is constantly on the decline with the destruction of forest.
Wrong. Dead wrong.
Globally, forests (tropical and mid-latitude) are NOT disappearing: today, they are 99.5% as much as they were at mid-century, and in the US in particular, have increased significantly.
CO2 has been much, much higher previously, and temps (at the same time) have been both much higher, and much lower, than now. There simply is NO link in ANY record at ANY time between CO2 levels and temperatures.
While the first of those statements is true - with some notable caveats - the second is clearly false.
