The atmospheric concentration of the trace gas CO2 is definitely NOT the only and simple answer to an understanding of how the climate is changing, and has been changing many, many times in the past.

In 1928, George Simpson published a memoir on atmospheric radiation, which assumed water vapour was the only greenhouse gas, even though, as Richardson pointed out in a comment, there was evidence that even dry air absorbed infrared radiation.

They include: (1) a 35 year US delay on climate action has made the problem extraordinarily challenging to solve, (2) US greenhouse gas (ghg) emissions are more than any country responsible for rise in atmospheric concentrations to present dangerous levels, (3) US ghg emissions not only threaten the US with climate disruption but endanger many of the poorest people around the world, (4) the Obama administration's pledge to reduce ghg emissions is far short of the US fair share of safe global emissions.

Only about 3 % of those four out of every 10,000 atmospheric CO2 greenhouse gas molecules have been added by humans.

The only researched and quantified contribution of atmosphere on global temperature has been that of applying the Ideal Gas Laws and insolation [familiar to those educated before the popularity of «back radiation»]- Nikolov and Zeller being one example using empirically derived data from other atmospheric bodies within the Solar System.

If the only way atmospheric gases could lose energy is by conductive contact with the night surface, tropospheric convective circulation would stall and our atmosphere would heat dramatically.

During dimming (1950s — 80s) the decline in surface solar radiation (SSR) may have outweighed increasing atmospheric downwelling thermal radiation (LW) from enhanced greenhouse gases and effectively counteracted global warming, causing only little increase in surface thermal emission (LW).

As a result, this paper asserts that to prevent dangerous climate change the world must not only reduce its emissions but reduce existing greenhouse gas CO2 atmospheric concentrations from the current 394 ppm to 350 ppm CO2 to avoid dangerous climate change.

Dennie: I am slowly coming to the realization that the planet is heating up not only from greenhouse gasses and aerosol particulates holding in heat, but that the major cause of the increased atmospheric heat is due to microwave technology and the exponential increase in its saturation of the entire global atmosphere.

The slowdown or «hiatus» in warming refers to the period since 2001, when despite ongoing increases in atmospheric greenhouse gases, Earth's global average surface air temperature has remained more or less steady, warming by only around 0.1 C.

After all CO2 is itself only a tiny portion of total greenhouse gases so that it can not have any significant long term effect when the water vapour primarily affecting atmospheric heat retention is in turn itself but a tiny proportion of global heat retaining capacity when one adds in the vastly greater oceanic heat retaining effect.

In that way we can allow factors other than mass, gravity and insolation to affect V without affecting T because T is determined only by the amount of KE needed to keep the mass of the atmosphere off the surface at a given height and in turn that is determined by mass (m) and the individual gas constant for the particular atmospheric composition (Rspecific).

A shallow sandstone might have 20 - 30 % of pore space, so at atmospheric pressure that would be 0.25 litres for every litreof rock, assuming gas only in the porespace.

Climate threshold - The point at which external forcing of the climate system, such as the increasing atmospheric concentration of heat - trapping gases (greenhouse gas es), triggers a significant climatic or environmental event which is considered unalterable, or recoverable only on very long time - scales, such as widespread bleaching of corals or a collapse of oceanic circulation systems.

That means the pressure inside the flask remains at atmospheric pressure through out, and only sealed once no more CO2 is being introduced, so there can be no warming by compression of the gas.

The Law Dome ice cores have an overlap of ~ 20 years with the atmosphere and reflect the atmospheric CO2 levels within + / - 1.2 ppmv for the same average gas age: The averaging makes that the ice core record lags the changes in the atmosphere and that fast peaks are suppressed, but for the Law Dome ice cores, any peak of 20 ppmv happening over only one year should be just detected or a 10 - year sustained 2 ppmv increase...

It is ignored in most assessments of atmospheric gases; they record only dry air at sea level.

For example, mainstream science not only correctly predicted the current ocean warming, but accounts all previous Earth warming episodes that involved increased atmospheric concentrations of greenhouse gases - due to the fact that over 90 % of heat goes into the oceans.

The (slightly heated) atmospehric gases now radiate a complete thermal spectrum continuum, depending ONLY on the atmospheric Temperature; AND THEN the CO2 or other GHG molecule can re-engage with THAT spectrum, and once again carve out its specific absorption band chunk.

The only function of the GHG molecules is to heat the atmospheric gases; along with all the other mechanisms that are heating it.
