If this is so , then a simple evaluation of the following graphs, for which there are either multiple sources, such as for the following ( from here ): or, from h...

Lately, the focus in things climate change has shifted from Thunberg (perceived cause: internal forces ) back to Milankovic (perceived cause: external forces ) and back again within just a few months. Nevertheless, the fact remains that, though astronomic or cosmic cycles and positions can be predicted with utmost precision, weather and climate on Earth still and most obviously can not ; it seems there may be other factors involved; like - well, perhaps, indeed, the makeup of the planet's atmosphere. So, the following is premised on the assumption that, just as does the Sun's intensity, the position of Earth in Space, and even its own geothermal heat, atmospheric carbon dioxide can and does influence this planet's surface temperature ; at least it is doing so under the current circumstances. If it doesn't, t...

Copied from  thermodynamicsociety.substack.com Causes and Effects of Climate Change Choosing the parameters As part of the planetary and terrestrial fauna , we as humans are completely insensitive to the atmospheric CO2 levels currently negligible to our wellbeing, which are, at the moment, being kept far below even the normal level in our own lungs by the constant effort of floral photosynthesis - to which these levels, especially if terrestrial, are crucial; so while the terrestrial fauna is insensitive to atmospheric CO2 levels as low as today, the flora most certainly is not . This differential sensitivity is reversed once atmospheric CO2 levels reach 2000 ppm (or 0.2% ) and above, or about ten times the current level ; at which point it begins to displace the atmospheric oxygen vital to terrestrial fauna; and these levels were reached in the distant past (it should be stressed that, though terrestrial and marine environments and life ultimately share t...

Copied from  thermodynamicsociety.substack.com Speculation, Suggestion and Mystery Speculations on the natural causes of climate change (and man’s possible role in it) Atmospheric CO2 is destroyed largely through being metabolized by plants via photosynthesis , combining them with water to form carbohydrates (CHx) and free oxygen (O2) as a waste product. Different specifications of photosynthesis In regards to terrestrial photosynthesis , which seems to be the more volatile one concerning its dependency on atmospheric temperature and carbon dioxide levels , and therefore the more susceptible to these (and more determining!) than marine algae, there seems to be two major types of plants to account for most of the biomass, labeled C3 and C4 , which process atmospheric carbon dioxide in a slightly different manner. Of these, C3 plants , constituting almost all trees , seem to posses the initial type of metabolism stemming from the primary evolution ...
