atmospheric increases in CO2 are due to the
gas coming out of the oceans, and here we are discussing the observation that the pH of the oceans are decreasing
because CO2 is dissolving in them?
I think you are getting confused from a statement about there being less CO2 in total (

atmospheric gases there... due to a combination of elevation and the fact that the air thins out more as you go up in elevation near the poles than elsewhere).

gases at the sea surface, ocean acidity and the
atmospheric carbon dioxide are related.

because of the capacity of such
gases to trap infrared radiation.
Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in

gas or
atmospheric mix then have to refer to a» green house effect»

because of their high per - molecule radiative forcing and long
atmospheric lifetimes.
Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades,
because, unlike carbon dioxide, these
gases and particles have relatively short
atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping
gases and particles.
Because allocation of national ghg emissions is inherently a matter of justice, nations should be required to explain how their ghg emissions reduction commitments both will lead to a specific
atmospheric greenhouse
gas concentration that is not dangerous, that is, what remaining ghg CO2 equivalent budget they have assumed that their commitment will achieve, and on what equitable basis have they determined their fair share of that budget.

gases: see «The
atmospheric greenhouse effect is more subtle than you believe» in La Météorologie (n ° 72 February 2011)
In that way we can allow factors other than mass, gravity and insolation to affect V without affecting T

gas constant for the particular
atmospheric composition (Rspecific).
The IPCC, its models, and the climate establishment insist warming will be more than this
because the warming will cause an increase in
atmospheric water vapor (the major greenhouse
gas) which will amplify the CO2 - caused warming, a net positive feedback.

The Montreal Protocol may have prevented the
atmospheric concentrations of chlorine from getting worse by getting rid of CFCs in developed countries (but the black market will ensure they are readily available in developing countries for years to come unless more is done soon), and
because the CFCs are enormously powerful greenhouse
gases (5000 - 11,000 time more powerful than CO2, in round figures) Montreal has done 5 times more to abate emissions than Kyoto will in the first commitment period.
Based on an extensive literature review, we suggest that (1) climate warming occurs with great uncertainty in the magnitude of the temperature increase; (2) both human activities and natural forces contribute to climate change, but their relative contributions are difficult to quantify; and (3) the dominant role of the increase in the
atmospheric concentration of greenhouse
gases (including CO2) in the global warming claimed by the Intergovernmental Panel on Climate Change (IPCC) is questioned by the scientific communities
because of large uncertainties in the mechanisms of natural factors and anthropogenic activities and in the sources of the increased
atmospheric CO2 concentration.

atmospheric particulate concentrations and their effects, and also
because of uncertainties in climate models.
But it is not a simple monotonic function of average specific humidity,
because water vapor is never a well mixed
gas, its
atmospheric lifetime (~ 9 days) is way too short for that.
Yet before writing tha book, Sorenson decided to go ahead and publish his 2011 article
