This one is going to leave a mark.. With CO2 only lasting around 20-40 years in circulation within our atmosphere the CO2 monster dies...
Simple Equation of Multi-Decadal Atmospheric Carbon Concentration Change. It is article-length (~5,000 words, not counting references), citable, and discoverable by search engines, including the
Climate Sanity and Freedom Search. In a slight departure from a widely-used academic format, the paper contains a Summary (for busy readers). The abstract is as follows.
"Surplus CO2 is removed from the atmosphere by natural sinks at rate, proportional to the surplus CO2 concentration. In other words, it undergoes exponential decay with a single decay constant. This conclusion is rigorously proven, using first principles and relatively recent observations of oceans. Historical data for CO2 concentrations and emissions from 1958–2013 are then used to calculate the half-life of the surplus concentration. This theoretically derived formula is found to be an excellent match to the historical CO2 concentrations over the measurement period. Furthermore, the “initial” CO2 concentration in the formula came out to be very close to the likely “pre-industrial” CO2 concentration. Based on the used datasets, the half-life of the surplus concentration of CO2 in the atmosphere is found to be approximately 40 years."
