The graphs of five-year running averages of hemispheric temperature in the figure below are generally similar.If you assume that most of the temperature rise has been due to increased CO₂ generated by industry that was primarily in the northern hemisphere,do the northern and southern hemispheres appear to have separate air circulation,with very little or no mixing of air between them?

A)yes
B)no

While the graphs of five-year running averages of hemispheric temperature are generally similar, there are still some differences in the fluctuations and trends between the northern and southern hemispheres. This suggests that there is some mixing of air between the two hemispheres. Therefore, it is unlikely that the northern and southern hemispheres have separate air circulation with very little or no mixing of air between them.
