The question of human influence, Anthropogenic Global Warming (AGW), is a hoax and a fraud as well. The Earth like most terrestrial planets had a second atmosphere upwards of 100 times more massive than it is at present. This 100 timews greater atmosphere was composed of greater than 96 percent Carbon dioxide (CO2). Almost all of this Carbon dioxide was removed from the atmosphere by Life, which deposited the carbon and some of the oxygen in the Earth’s lithosphere as carbonate and other rocks, like the chalk cliffs of Dover.
Today, the Carbon dioxide in the Earth’s atmosphere is measured in so many parts per million, bcause it is nearly all gone from the atmosphere. They are arguing over the differences between 290 ppm (parts per million), 340 ppm, 360ppm, and so forth. In other words, they’re arguing over one or few tens of parts per million of atmospheric CO2 concentrations. Compare the tens of parts per million changes to the changes wroguht by Life before the presence of humans and human civilizations. Life reduced 100 atmospheres with more than 96 percent concentrations of CO2 to the present concentrations, which is greater than 960,000 parts per million down to aaround 290 to 280 parts per million. In other words, Life consumed something on the order of 959,600 ppm of one current atmsophere times 100 atmospheres of Carbon dioxide and depsoited it into rocks and carbon based lifeforms.
The process continues today, with the process leaving many forms of palnt life starving for more carbon dioxide than is presently available from the atmosphere. Grasses developed a new biochemical means of getting around the shortage of atmospheric Carbon dioxide, long befoer humans were around to influence anything.
Among the many sources of Carbon dioxide emissions into today’s atmosphere, humans are without any doubt whatsoever a nearly insignicant contributor, being responsiblee for only a few percent of such CO2 emissions. Then you have to take those few percent of emissions and note that the combustion of fossil fuels is responsible for something like less than half of anthropogenic CO2 emissions. The maor source of human emissions comes from the production and usage of cement. There is some usage of fossil fuels to calcine the rosck to produce cement, but much of the CO2 emissions from cement comes from the mining of the source rock, handling of the processed cement, and the usage of the cement to build roads and buildings. Restrictions upon theusage of fossil fuels can therefore reduce CO2 emissions by only one or two percent, and only by immediately stopping the use of all fossil fuels from petroleum and natural gas to tribesmen burning firewood throughout the whole planet.
Conversely, the planet’s biosphere naturally varies its emissions and consumptions of carbon dioxide by many percentage points. Life can literally eat Carbon dioxide faster than himans can emit Carbon dioxide, despite the scaremongering claims to the contrary. If anything, the Earth needs more atmospheric Carbon dioxide to prevent the shutdown of photosynthesis in the Plant Kingdom essential to the survival of Life on the Earth as the planet’s atmosphere naturally continues to be thinned by the Solar winds.
But all in one direction. The much larger natural fluxes go in both directions. The ocean used to be a net source of CO2, particularly with the warming from Little Ice Age. Now it is a net sink of CO2 and absorbs about 1/2 of manmade CO2.

Probably a bit more, but at a large economic cost. There is a distinct correlation between the economic downturn and our decreasing emissions.

Right now the ocean is mostly eating CO2. Plant life can eat a lot too, but only if we increase its area (e.g. rainforests). Your last point is good and worth emphasizing. Until we started raising the level of CO2 from roughly 280, the planet was literally CO2 starved. The evolution of grasses was the final nail in the CO2 coffin since they are so adept at sucking CO2 out of a CO2-starved atmosphere. We are currently within a long term ice age and a return to glacial conditions was inevitable. Even another Little Ice Age would have made it extremely difficult to feed mankind. But those fears are over for now.
