In the podcast we mention the ‘Keeling curve’ which is a graphic showing carbon dioxide concentration in the atmosphere, measured since 1958.
See an image of the Keeling curve below.
Atmospheric carbon dioxide concentrations taken from the ice core record over the past 800,000 are shown here:
Note the almost vertical spike in CO2 concentrations in the past century.
