What is the carbon cycle and how is it affecting climate change?

The carbon cycle is nature's way of recycling carbon atoms. Carbon is the foundation for all life on Earth.

Explanation:

The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist. Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
