Why is there less CO, in the atmosphere during summer in the Northern Hemisphere compared to summer in the Southern Hemisphere? O The strong westerlies in the summer mix atmospheric CO, and dilute instrumental readings. Northern Hemispheric plants are more effective at sequestering CO,. The northern shift in the ITCZ transports CO, higher into the atmosphere away from meteorological instruments O There is greater land mass in the Northern Hemisphere.
