A greenhouse gas is a gas that traps heat in Earth's atmosphere, helping to keep our planet warm enough for life. The main greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), which come from things like burning fossil fuels, agriculture, and waste. These gases contribute to climate change by making the Earth warmer, leading to problems like melting ice and more extreme weather.
