Question 45
F

The table shows the mean carbon dioxide concentration in the atmosphere and the global temperature for six years.

YearCarbon dioxide concentration (ppm)Global temperature compared with the long-term mean (∘C^\circ\mathrm{C}∘C)
2014397+0.75
2015399+0.90
2016403+1.01
2017405+0.92
2018407+0.85
2019410+0.98

Which conclusion is best supported by the data?

[1]
A

The data prove that the rise in carbon dioxide concentration caused the rise in temperature.

B

The temperature rose by the same amount each year as the carbon dioxide concentration rose.

C

There is no link, because the temperature fell in some years while carbon dioxide rose.

D

Both generally increased, but the data alone do not show that one caused the other.
