This Demonstration plots the Keeling curve for the concentration of in the atmosphere (in parts per million), from 1958 to 2016, using data courtesy of NOAA [1]. It also includes a plot of the change of growth per year and some model predictions to 2070, including neural network, random forest and linear regression.
