Mauna Loa and South Pole Difference with Fossil Fuel


Description

Black Dots: Difference of the seasonally adjusted monthly average atmospheric carbon dioxide concentration at Mauna Loa Observatory, Hawaii and South Pole, Antarctica versus time where CO2 concentration is in parts per million in the mole fraction (p.p.m.).

Black Curve: Spline fit to the CO2 data.

Red Curve: Fit to the CO2 data in the form of A + B·FF where A and B are constants that are adjusted to optimally fit the data and where FF is the global fossil fuel emissions in PgCyr-1. The values of the constants are A = -0.82 ppm CO2 and B = 0.513 ppm CO2/(PgCyr-1).

Data from Scripps CO2 Program.
