The carbon cycle and global warming are intrinsically linked.
The carbon cycle is responsible for regulating the amount of carbon dioxide in the atmosphere.
Carbon dioxide is the most important greenhouse gas, trapping solar heat in the atmosphere, and hence the carbon cycle is crucial in maintaining Earth's temperature.
The combustion of fossil fuels emits a significant amount of carbon dioxide.
Cutting down trees limits photosynthesis and carbon dioxide utilization, contributing to a rise in CO2 levels.
Such carbon cycle disruptions are important contributors to global warming and climate change.
