A line graph that shows the last 2000 years of greenhouse gas concentrations. The x-axis represents the years, starting from the top left corner of the graph and ending at the bottom right corner. The graph has three lines, each representing a different year. The first line is labeled "CO2", the second line is colored in orange, the third line is blue, and the fourth line is green. The lines are plotted on a transparent background, and each line has a different color - blue, orange, and green. There are two lines on the graph, one in blue and one in green, representing CO2 and the other in orange. The blue line represents CO2, while the orange line represents N2. The green line represents the CO2 concentration, which is represented by a blue line. The graph also has a red line representing N3, which represents N4, which means N5, and a green line representing the N6, respectively. - The graph shows that CO2 has been steadily increasing over time, with the highest concentration at the beginning of the year and the lowest concentration in the last two years.
