kasvadioksidin

Kasvadioksidi, also known as carbon dioxide or CO2, is a colorless, odorless gas that is a natural component of Earth's atmosphere. It is composed of one carbon atom and two oxygen atoms, and is a product of both natural and human-induced processes. In the natural carbon cycle, CO2 is released through respiration, volcanic activity, and the decay of organic matter. It is also absorbed by plants during photosynthesis, which helps to regulate the Earth's climate.

Human activities, particularly the burning of fossil fuels for energy, deforestation, and industrial processes, have significantly increased the concentration of CO2 in the atmosphere. This increase is a major contributor to global warming and climate change. CO2 is a greenhouse gas, meaning it traps heat in the Earth's atmosphere, leading to rising temperatures and changes in weather patterns.

The measurement of CO2 levels in the atmosphere is crucial for understanding and mitigating climate change. The concentration of CO2 is typically expressed in parts per million (ppm). As of recent data, the global average concentration of CO2 has exceeded 400 ppm, a level not seen in millions of years.

Efforts to reduce CO2 emissions include transitioning to renewable energy sources, improving energy efficiency, reforestation, and the development of carbon capture and storage technologies. These measures aim to lower the concentration of CO2 in the atmosphere and mitigate the impacts of climate change.
