The histograms show the average global temperature per year for two 26-year ranges in degrees Fahrenheit. The range for 1880 to 1905 is on the top, and the range for 1980 to 2005 is on the bottom. Compare the two histograms for the two time periods, and explain what they show. Also estimate the difference between the centers. That is, about how much does the typical global temperature for the 1980-2005 time period differ from that for the 1880-1905 period? (Source: Goddard Institute for Space Studies, NASA, 2009)
