The recent discovery of long term growth constants in the accumulation ofatmospheric CO2, confirmed by two methods, enables analog methods for datingthe beginning of climate change at ~1780 and projecting its near term future.Here we show that the preceding wavy variation in CO2 PPM abruptly shifts toexponential, moving symmetrically around a growth constant of 1.48 %/yr untilWWII, and after a pause rises to hover about a higher constant growth constantfrom 1960 on of 2.0 %/yr. Such long term steady states of global environmentalchange suggest transitions between stable states of global self-organization. Amethod of analog curve fitting to project the current steady state ofacceleration is tested, suggesting a 2040 earth temperature rise of 1.89 deg Cabove the IPCC baseline. A very brief following discussion of what a systemicgrowth constant for atmospheric CO2 implies and model strategies for respondingto it.
