You use a y that carries 1,000 years in a quarter of an inch. The 1/8 inch where the CO2 spike resides shows a huge uptick, granted, but unimpinged by the last 150 years of the IR. Que paso?
Also, earlier you show a 45ppm increase over the last 50 years. At 3% manmade, that is a total ACO2+ of 1.35 ppm. In fifty years? It works out to .0270 ppm/year? Please do check my math.
