According to an August 2011 report from the government research laboratory known as NOAA-ESRL, the amount of carbon dioxide in Earth's atmosphere increased by almost 25% (from 315 ppm to 392 ppm) between 1958 and 2011. The graph below illustrates this increase as well as the yearly cycle, which is driven by the seasons. Image courtesy of NOAA A scientist wants to study how this change in carbon dioxide in Earth's atmosphere is correlated with temperature change on Earth. It would be best for the scientist to compare the data in the graph above to which of the following? A. a graph showing the annual average global temperatures for 1958 through 2011 B. a graph showing the annual low temperatures in one city for 1958 through 2011 C. a table showing the average high and low temperatures in various cities in 1958 D. a table showing the average high and low temperatures in various cities in 2011
