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

Quizplus · Accepted Answer

The fact that the graphs of five-year running averages of hemispheric temperature are generally similar indicates that the northern and southern hemispheres share a common climate system and experience some degree of air mixing. While it is true that the industrial revolution and subsequent CO₂ emissions have primarily occurred in the northern hemisphere, the global climate system is a complex and interconnected system in which air travels great distances and can mix between hemispheres. Thus, it is unlikely that there is very little or no mixing of air between the hemispheres.
