Some scientists believe that greenhouse gas emissions from transportation are a major contributor to global climate change.

The graph below shows the relative carbon dioxide (CO2\text{CO}_2CO2​) emissions from the transportation sector in the United States and the relative change in global average surface temperature between the years 2000 and 2020.

Line graph showing USA transport \text{CO}_2 emissions and change in global average temperature from 2000 to 2020. The x-axis is Year, ranging from 2000 to 2020 in 5-year intervals (2000, 2005, 2010, 2015, 2020). The left y-axis represents 'Relative carbon dioxide emissions from US transport' (solid line), which starts at a high level in 2000, rises slightly to a peak in 2005, then decreases steadily with some fluctuations down to a much lower level in 2020. The right y-axis represents 'Relative change in global average surface temperature' (dotted line), which starts at a low level in 2000 and steadily rises with minor fluctuations up to its highest level in 2020.

a.

Evaluate the information shown in the graph. To what extent does the graph support a link between emissions from transportation and global warming?

[3]
b.

Suggest two problems with using information about US transport CO2\text{CO}_2CO2​ emissions to draw conclusions about global temperature changes.

[2]
c.

Describe one effect of global warming on the environment, other than rising average surface temperatures.

[1]
d.

Suggest one way human activity can be modified to reduce carbon dioxide emissions from transportation.
