CO2
CO2 stands for carbon dioxide, a colorless, odorless gas that is naturally present in Earth’s atmosphere in trace amounts. It is composed of one carbon atom and two oxygen atoms. Here are some key points about CO2:
Natural Presence: CO2 is produced by natural processes such as respiration, decomposition, and volcanic eruptions. Plants absorb CO2 during photosynthesis, converting it into oxygen and glucose.
Role in Climate Change: CO2 is a significant greenhouse gas, contributing to global warming and climate change. Increased levels of CO2 in the atmosphere, primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes, trap heat and lead to temperature rises.
Sources of Emission:
- Transportation (cars, airplanes)
- Electricity generation (coal-fired power plants)
- Industrial processes (cement production)
Measurement: CO2 concentrations are typically measured in parts per million (ppm). As of recent years, atmospheric CO2 levels have exceeded 400 ppm, compared to about 280 ppm before the Industrial Revolution.
Uses: CO2 has various applications, including:
- Carbonation in beverages
- Refrigeration
- Fire extinguishers
- Agriculture (as a component of controlled-environment agriculture)
Impact on Oceans: Increased CO2 levels also lead to ocean acidification, which can harm marine life, particularly organisms that rely on calcium carbonate for shells and skeletons.
