CO2 levels fluctuate during the year as vegetation grows in spring then decomposes. Levels peak during April and May, when the large amount of vegetation in our hemisphere release carbon dioxide.

The article points out that CO2 is the primary driver of global warming and can remain in the atmosphere for hundreds of years.
