Carbon dioxide (CO2) is the gas primarily responsible for climate change. It is emitted through natural processes and human activities, notably from the burning of fossil fuels like coal, oil, and natural gas. Deforestation and industrial processes also contribute to increased CO2 levels in the atmosphere. Elevated concentrations of carbon dioxide trap heat in the earth’s atmosphere, leading to global warming and subsequent changes in climate patterns. Efforts to mitigate climate change often focus on reducing carbon emissions and transitioning to renewable energy sources to lower the overall concentration of CO2.
