Why is the CO₂ Concentration Rising?

The general view in society is that human emissions of CO₂ are the all-determining cause of the increased concentration in the atmosphere. Most scientists and even many climate skeptics do not question this. There is some debate about how long this extra CO₂ will stay in the atmosphere, but that’s about it. That’s remarkable, as several scientists have published extensively on the flaws and inconsistencies of this narrative. By looking at the significant increase in the CO₂-flows from and to land and sea it’s in fact easy to see that the CO₂-rise is largely due to natural causes.
The idea that human CO₂ is the all-determining cause of the increased concentration is based on the assumption that the natural inflows and outflows are always and exactly in equilibrium with each other. Based on this perfect equilibrium thinking, human emissions, even though they are relatively small, cause a perturbation year after year. In the so-called global carbon budget[2] about 10 PgC of CO₂ is added every year, while the absorption flux has only increased by 6 PgC/yr (1 Petagram = 1 Gigaton = 1 billion tons). The concentration therefore continues to rise indefinitely as long as people emit CO₂.
To support this idea it is also assumed that human emissions accumulate in the atmosphere. Where you would expect a single residence time for a reservoir with in- and outflows, the IPCC-models calculate with a small residence time of about 4 years for natural CO₂ and a large one for human CO₂: “The removal of all the human-emitted CO2 from the atmosphere by natural processes will take a few hundred thousand years (high confidence)”.
