Final answer:
The time series of atmospheric CO2 at the South Pole has higher seasonal variation compared to the Mona Loa curve. The South Pole record has higher seasonal variation due to the limited vegetation and lower rate of photosynthesis in the area, resulting in less removal of CO2 from the atmosphere during the growing season.
Step-by-step explanation:
The time series of atmospheric CO2 at the South Pole can be compared to the Mauna Loa curve, which is the record of CO2 concentration measured in the middle of the Pacific Ocean. Both records show an increasing trend in CO2 levels over time. However, the South Pole record has higher seasonal variation compared to the Mauna Loa curve.
One reason for the higher seasonal variation at the South Pole is the difference in vegetation between the two locations. The South Pole has a very limited amount of vegetation, leading to less photosynthesis and thus less removal of CO2 from the atmosphere during the growing season.
In contrast, Mauna Loa is located in an area with more vegetation and a higher rate of photosynthesis, resulting in greater removal of CO2 during the growing season and lower seasonal variation.
