Do you also think it is an absurd conceit to believe that humans can
have a significant impact on atmospheric CO2 levels?

Not the same thing.

Do you normally compare apples with oranges ?

Unfortunately, the comparison is oranges and oranges. You obviously don't
understand that the rising atmospheric CO2 levels are affecting the
climate -

No, but I do acknowledge that CO2 levels actually _follow_ temperature
changes.

Since human activity started significantly transfering carbon from the
lithosphere to the atmosphere/hydrosphere/biosphere, it looks to me that
things have been the other way around. Do consider that about half of
post-Industrial-Revolution global warming occurred after 1980.

Although from about half a million years ago to a couple hundred years
ago when the amount of carbon in the combination of
atmosphere/hydrosphere/biosphere was constant, it did shift to the
atmosphere from the hydrosphere as a result of temperature rise, and the
other way as a result of temperature drop, causing positive feedback that
amplified the effects of the Milankovich cycles, especially the 95,000
year one.

In the past several decades, concentration of CO2 in both the atmosphere
and the oceans has increased. In the roughly half million years before
the Industrial Revolution, warming cycles decreased CO2 content in the
oceans by shifting CO2 from ocean to atmosphere.
