Just how much do your "peer reviewed scientists" imagine that the earth can be warmed by anthropomorphic forces?
The chart below, which is figure 7-8 at
http://acmg.seas.harvard.edu/people/faculty/djj/book/bookchap7.html, shows, by simple inspection, that the CO2 in the atmosphere is currently blocking upwards of half of the total upward radiation it could block if the atmosphere were sufficiently rich in CO2 to render it totally opaque to radiation in the range of wavelengths that CO2 absorbs, which is 14 to 18 micrometers. That is, CO2 is already absorbing upwards of half the total upward radiation it could absorb if the atmosphere were 100% CO2!
Now the data from your “peer-reviewed” scientists, which you included in post #96 of this thread, says that CO2 is currently absorbing 1.7 watts per square meter of this upward radiation. If we give you the benefit of the doubt and say that an additional 1.7 watts per square meter of upward radiation could be absorbed, let’s see what happens when we apply this number to the data in your diagram titled “The Greenhouse Effect,” from your same post #96 in this thread. Since all the numbers in this diagram are in watts per square meter, I will not repeat this unit each time I use data from your diagram. Nor will I say allegedly, or supposedly, as would properly be added to each of these numbers.
The atmosphere is currently absorbing 67 from the sun and 452 from the earth, making a total of 519. The atmosphere is currently re-radiating 195 into space and returning 324 to earth. This 324 is 62.4% of the total 519 the atmosphere absorbs. So 62.4% of the additional 1.7, or 1.06 watts per square meter, is the maximum heat that can be added to the earth, even if the atmosphere were increased to 100% CO2.
Now how much can that additional 1.06 watts per square meter heat the earth? The earth is currently receiving 168 from the sun and 324 from the atmosphere, for a total of 492. This heats it to 14 degrees C, or 287.15 K. Increasing the heat input by 1.06 could then increase the absolute temperature to a maximum of 287.15 * (492 + 1.06) / 492 = 287.77 degrees K, or 14.62 degrees C.
This calculation is greatly oversimplified to make it easier to understand. For instance, it does not take into effect the fact that temperature is not directly proportional to radiative energy, as this oversimplified calculation assumed. It also does not take into effect the additional outgoing radiation that would result from any temperature increase, or the fact that this heat increase would move the radiation curve further away from the peak absorption region for CO2. Nor does it take into effect the fact that the internal heat from the center of the earth also affects its surface temperature. But all those considerations would make the calculated available temperature increase even less that that shown in this oversimplifiction.
Even with all these simplifications, this calculation clearly demonstrates that the maximum increase in the earth’s temperature that could be caused by increasing the CO2 content of the atmosphere to 100%, would be just over 0.6 degrees C. Such facts, which can be readily deduced by simple calculations, show why so few physicists, engineers, and others who know the real facts of the physical sciences involved, are deceived by the myth of "Anthropometric Global Warming."
Are we expected to believe that a grand total available temperature increase of just over half a degree C could make the polar icecaps melt, flooding the coastal areas, and completely change our climate? That is only slightly more that your "peer-reviewed" scientists claim it has already increased, as shown in the chart in your post #122. Yet we have experienced neither any significant rise in sea levels or any drastic changes in climate.
