Some simple numbers on the effect of CO2 concentration on temperature
As the temperature increasing effect of atmospheric CO2 is known to diminish logarithmically with increasing concentration, these notes clarify the actual amount of warming that might result from additional CO2 released into the atmosphere by man-kind and the temperature reduction impact of any policy actions to control CO2 emissions.
To understand exactly what might be achieved by political action for de-carbonisation the table below gives the likely warming, (without positive or negative feedbacks), that will be averted with an increase of CO2 from 400 ppmv to 800 ppmv, a full extra 400 ppmv, assuming that the amount of CO2 released by all world nations in future is reduced in future by 50%.
