Atmospheric sampling networks keep track of the gases in the troposphere, the layer of Earth’s atmosphere near the surface, as they vary in time and space; space- based sounders are providing continuous measurements of some gases from satellites Ocean sampling networks are reaching similar levels of coverage Our capacity to manage large quantities of data has grown enormously Earth systems models are getting more sophisticated

The figure shows concentrations of carbon dioxide at the Mauna Loa Observatory, Hawaii (Latitude 19 N) over a ten-year period. Draw the comparable patterns for Barrow, Alaska (Latitude 71 N) and the South Pole (Latitude 90 S) on these same axes. It’s not important to get the values right, of course – but do your best to show how they compare to Mauna Loa, in position and magnitude.
