Why are carbon dioxide levels in the air higher in winter compared to summer?

Answer 1

In the northern winter since plants are dormant and not taking carbon dioxide from the atmosphere.

The Northern Hemisphere has much more land for vegetation to grow on compared to the Southern Hemisphere. Carbon dioxide (CO2) builds up slowly during the northern winter, when trees and plants are dormant. It generally reaches its highest level in May of every year.

Answer 2

In the northern winter carbon dioxide levels rise in the atmosphere. This is because trees and other vegetation are not growing and so are not removing carbon dioxide from the air.

Answer 3

Because the photosynthesis rate in the summer is higher, for the declination of the sun is higher in summer and the days are longer. Also, when plants are in the dark they reverse the photosynthesis process, turning oxygen and carbohydrates into carbon dioxide. So, not only is there a increase in production, but there is also a decrease in absorption.

During the summer, most of the flora is in bloom and is able to receive the carbon dioxide and change it into oxygen. During the winter, though, most of the flora is dead (or at least not in bloom) and therefore cannot intake any carbon dioxide.

Answer 4

During the summer in the northern hemisphere (where most of the vegetation is) trees and plants grow, removing carbon dioxide from the atmosphere. This lowers levels in the atmosphere. During winter, when the trees and vegetation are dormant, levels rise again.

Answer 5

The northern winter is the peak season for carbon dioxide (CO2) since plants are dormant and not taking CO2 from the atmosphere.

The Northern Hemisphere has much more land for vegetation to grow on compared to the Southern Hemisphere. Carbon dioxide builds up slowly during the northern winter, when trees and plants are dormant. It generally reaches its highest level in May of every year.

Answer 6

In the summer there is higher plant growth, so more carbon dioxide is removed from the atmosphere. The opposite happens in winter, so carbon dioxide from fossil fuel burning builds up more quickly.

Answer 7

Yes, CO2 levels actually increase in the northern winter because trees and vegetation are not growing, so they are not removing carbon dioxide from the atmosphere.

Answer 8

CO2 is used by growing plants. Which grow in the spring and summer. In fall and winter, we also increase burning of fuel for heating, which can release CO2.
