2. The graph below from NOAA Climage. gov gives two important pieces of data.
It shows the difference from 20th century temperature averages in a bar graph -
blue bars show temperatures below the average, and red bars show how much
above average the temperature was. It also shows CO2 levels during the same
period of time in the gray line. What correlation do we observe in this data? *

O A. When carbon dioxide levels increase, temperature also increases.
OB. When carbon dioxide levels increase, temperature decreases.
C. There is no relationship between carbon dioxide levels and temperature, according
to this data.
