Carbon Dioxide (CO2)

Carbon dioxide (CO₂) is a naturally occurring gas that plays a vital role in Earth's carbon cycle and is essential for plant life through the process of photosynthesis. It is a colorless, odorless gas that is released into the atmosphere through natural processes such as respiration, volcanic eruptions, and the decomposition of organic matter. However, human activities, including the burning of fossil fuels, deforestation, and industrial processes, have significantly increased atmospheric CO₂ concentrations since the Industrial Revolution.

Key aspects of carbon dioxide include:

Principal Greenhouse Gas: Carbon dioxide is the primary anthropogenic greenhouse gas that contributes to global warming. It enhances the greenhouse effect by trapping heat in the Earth's atmosphere, leading to rising temperatures and climate change.
Global Warming Potential (GWP): CO₂ is used as the baseline for measuring the GWP of other greenhouse gases, with a GWP value of 1 over a 100-year period. This makes it a reference point for comparing the impact of other gases on global warming.
Ocean Acidification: Elevated levels of atmospheric CO₂ contribute to ocean acidification. When CO₂ dissolves in seawater, it forms carbonic acid, lowering the ocean's pH and posing risks to marine ecosystems such as coral reefs and shellfish populations.

Addressing carbon dioxide emissions is critical for mitigating climate change. This involves transitioning to renewable energy sources, enhancing energy efficiency, adopting sustainable land use practices, and implementing carbon capture and storage technologies to reduce atmospheric CO₂ concentrations.
