    Forests potentially contribute to global climate change through their influence on the global carbon (C) cycle. They store large quantities of C in vegetation and soil, exchange C with the atmosphere through photosynthesis and respiration, are sources of atmospheric C when they are disturbed, become atmospheric C sinks during abandonment and regrowth after disturbance, and can be managed to alter their role in the C cycle.
