Question

How can the carbon cycle affect our climate?

Answer 1

The most impact is from the “Greenhouse effect” of carbon dioxide in the atmosphere, which stabilizes temperatures in a range that supports life (as we know it).

Explanation:

The “carbon cycle” is most often discussed because of its impact on and effects from atmospheric `CO_2` content. The most impact is from the “Greenhouse effect” of carbon dioxide in the atmosphere, which stabilizes temperatures in a range that supports life (as we know it).

Too little atmospheric `CO_2` could lead to a much colder planet, reducing the available ranges crops, animals and conditions for comfortable living. Too much – the modern concern – and it could lead to a much warmer planet.

Both scenarios will achieve a different equilibrium. Whether one is preferable to the other is a more philosophical and political question than a scientific decision.
