atmospheric carbon dioxide

Atmospheric carbon dioxide (CO₂) is a natural greenhouse gas present in Earth's atmosphere. It is produced by processes like respiration, decomposition, and volcanic activity, and released into the air through human activities such as burning fossil fuels and deforestation. CO₂ helps trap heat in the atmosphere, maintaining the planet's temperature. However, excessive CO₂ from human sources has increased its concentration, intensifying the greenhouse effect and contributing to global warming. Managing CO₂ levels is crucial for maintaining climate stability and protecting ecosystems worldwide.
