Forests act as carbon sinks, meaning they absorb carbon dioxide () from the atmosphere during photosynthesis and store it in trees and soil. When forests are cut down or burned (deforestation), the carbon stored in trees is released back into the atmosphere as , a major greenhouse gas.

This release of carbon dioxide contributes to global warming and climate change by increasing the greenhouse effect, where heat is trapped in the Earth's atmosphere.
