Quizplus · Accepted Answer

CO2 (carbon dioxide) is the greenhouse gas most commonly associated with human-induced climate change. Activities such as burning fossil fuels and deforestation release large amounts of CO2 into the atmosphere, which traps heat and contributes to global warming. CO (carbon monoxide) has also been linked to air pollution and health concerns, but it is not a significant contributor to climate change. GMT (global mean temperature) is a measure of the average temperature across the entire planet and is affected by multiple factors, including greenhouse gas concentrations. CH4 (methane) is another powerful greenhouse gas, but its contributions are not as large as CO2.
