I have not read on this Wiki page a mention of an important mitigating (degenerative) feedback path associated with the concentration of earth's atmospheric CO2, which I understand to be 4/10,000 or 0.04% of the total mass of earth's atmosphere, up from 2/10,000 75 years ago, which increase is highly correlated with the 2 deg. Celsius increase in world surface temperature in the same period of time. The page mentions various factors that act to reduce the concentration of atmospheric CO2 including reforestion & dissolving of CO2 into the oceans. What is not mentioned is the well-established effect of increased CO2 concentration on the growth of green plants, which may have mitigated the increase in both atmospheric CO2 and world surface temperature during the last 75 years. My guess is that civilization's huge increase in CO2 releases has stimulated the growth of green plants resulting in an increase in sequestration of carbon by trees that did not fall victim to lumbering and forest fires. Sequestration of carbon by trees has acted to minimize atmospheric concentration of CO2 throughout most geologic ages, until recently. Now, even without deforestion and widespread forest fires, enhanced tree growth cannot sequester carbon at the rate it is being released by industrial civilization, so accumulation of atmospheric CO2 continues apace. How and why it is that a doubling of CO2 to a minuscule 0.04% of the atmosphere in 75 yrs should be the root cause of the 2 degrees C. of global warming that has certainly happened in the same period of time...is not explained well, if at all. However lacking the explanation may be, the temperature plot at the top of the page suggests that another doubling of atmospheric CO2 would indicate that that the corresponding increase in world surface temperature would be GREATER than 2 deg.
