Why does the oxygen level in the air doesn’t change dramatically, when most of the trees shed their leaves in the winter?
In: Earth Science
There is an extreme amount of oxygen in the atmosphere. We have enough oxygen in the atmosphere to last for maybe a thousand years of winter. So we do not notice much of a difference in the oxygen levels between summer and winter, even though there is a tiny bit. What we can measure this better is in the carbon dioxide levels. There is more landmass in the northern hemisphere then in the southern hemisphere. So there is more trees and vegetation in the northern hemisphere then the southern. This means that more carbon dioxide is converted into oxygen when it is summer in the north then when there is summer in the south. And since there is not that much carbon dioxide in the atmosphere this does make out a noticeable change in levels. The difference is about 5ppm. That used to be a greater then 2% change in carbon dioxide levels but is now fast approaching only 1% due to the increasing levels of carbon dioxide in the atmosphere.
