carbon dioxide
Greenhouse gas exhaled
Carbon dioxide is a colorless, odorless gas composed of one carbon atom bonded to two oxygen atoms (CO₂).
It occurs naturally in Earth's atmosphere and is produced by respiration, combustion, and decay.
Plants absorb it for photosynthesis.
Carbon dioxide is central to climate change discussions because burning fossil fuels releases it in quantities that trap heat in the atmosphere.
Carbon dioxide levels have risen sharply since the Industrial Revolution.
