Im doing this lab too and it sucks
1) The percentage in carbon dioxide in the atmosphere between 2015 and 2019 and between 1960 and 2015 are respectively; 2.98% and 27.13%
2) The fluctuation in the carbon dioxide levels each year is due to the fact that; Carbon dioxide fluctuation is a direct response due to photosynthesis and respiration increase in spring and summer and decrease in fall and winter.
According to a WMO report in 2019 on greenhouse gas concentrations, it was discovered that carbon dioxide growth rates were nearly 20% higher than the previous five years and that the percentage increase from 2015 and 2019 was approximately 2.98% while further research showed that from 1960 to 2015, it was approximately 27.13%
Lastly, the reason for these fluctuations in growth rate of carbon dioxide in the atmosphere is due to photosynthesis and respiration increase in spring and summer and decrease in fall and winter.
