Question

1. figure 6 above shows the effect of atmospheric carbon dioxide concentrations on global temperature. what trend do you see? figure 6. the effect of atmospheric carbon dioxide on global temperature. figure 7. satellite image of polar ice cap coverage sep 1984 sep 2016

Explanation:

Step1: Analyze Figure 6

As the $CO_2$ concentration (in ppm) increases over the years from 1880 - 2000 on the x - axis, the global temperature (in °F) on the y - axis also shows an upward trend.

Step2: Analyze Figure 7

Comparing the satellite image of the polar ice cap in September 1984 and September 2016, the polar ice cap coverage in 2016 is less than that in 1984, indicating a decrease in polar ice cap coverage.

Answer:

From Figure 6, as atmospheric carbon - dioxide concentrations increase over time, global temperature increases. From Figure 7, the polar ice cap coverage decreases from 1984 to 2016.
