Gas content in ice reacts with the atmosphere down 50 to 80 meters. That means co2 and other gases can and do escape back into the air. Because the gas can move around freely up to that depth, there is a physical smoothing of the remaining gas of 10-30 years. These two factors explain the low levels and flatness of the curve of ice held co2 without looking for further explanation.

Environmental Effects of Increased Atmospheric Carbon Dioxide
ARTHUR B. ROBINSON, NOAH E. ROBINSON, ANDWILLIE SOON
An exposition of what co2 is and is not responsible for.
ABSTRACT A review of the research literature concerning the environmental consequences of increased levels of atmospheric carbon dioxide leads to the conclusion that increases during the 20th and early 21st centuries have produced no deleterious effects upon Earth’s weather and climate. Increased carbon dioxide has, however, markedly increased plant growth. Predictions of harmful climatic effects due to future increases in hydrocarbon use and minor green house gases like CO2 do not conform to current experimental knowledge. The environmental effects of rapid expansion of the nuclear and hydrocarbon energy industries are discussed.
