Browsing: Carbon Dioxide

Carbon dioxide (CO2) is a colorless, odorless gas that plays a vital role in Earth’s atmosphere and biological systems. Produced naturally through processes like respiration, volcanic eruptions, and decomposition, it is also emitted in large quantities by human activities such as burning fossil fuels and deforestation. CO₂ is essential for photosynthesis, enabling plants to convert sunlight into energy, but its increasing concentration in the atmosphere is a major driver of climate change. Scientists closely monitor carbon dioxide levels to understand their impact on global temperatures, ocean chemistry, and ecosystems, making it a central topic in environmental and climate research.
