Figure 5 is an interactive line graph that plots greenhouse gas concentrations on the y or vertical axis, against year from 1850 to 2020 on the x or horizontal axis. On the interactive, the horizontal axis can be expanded to beyond 2100 and the vertical axis can be expanded to beyond 2000 ppm. The graph has 3 data sets: carbon dioxide concentrations, which rise from 286.8 ppm in 1850 to 391.6 ppm in 2011 and then 398.6 ppm in 2014; methane concentrations, which rise from 801.6 ppb in 1850 to 1803.0 ppb in 2011, and nitrous oxide concentrations, which rise from 270.4 ppb in 1850 to 324.0 ppb in 2011.
