Worldwide seasonal effects in carbon dioxide in the northern and southern hemispheres cancel each other out.

Question

Quizplus · Accepted Answer

The seasonal effects in carbon dioxide levels are more pronounced in the Northern Hemisphere due to its greater landmass and extensive vegetation. During spring and summer, plants absorb a significant amount of CO2, leading to lower atmospheric CO2 levels. In contrast, the Southern Hemisphere, with its vast oceans and comparatively less vegetation, does not exhibit as strong seasonal swings in CO2 levels. Therefore, the effects do not cancel each other out; instead, they contribute to a global seasonal cycle dominated by Northern Hemisphere processes.
