The vertical axis on the left is labeled CO2 ppm and ranges from 250 to 390 in increments of 20. The vertical axis on the right is labeled temperature and ranges from 13.5 to 14.5 in increments of 0.2. The horizontal axis is labeled year and lists dates from 1000 to 2000 in increments of 100. The graph is a line fluctuating between 270 and 305 from left to right. The line slopes upward near the right end toward the upper right corner.

1 answer
Based on the description of the graph and the relationship between the concentrations of atmospheric carbon dioxide and average global temperatures, the best response is:
Both carbon dioxide and global temperatures begin to increase significantly after the Industrial Revolution that ended in 1840.
This response reflects the observed trend of rising CO2 levels and global temperatures during that period.
