Greenhouse gases trap heat in the atmosphere through a process called the greenhouse effect Having some greenhouse gases in the atmosphere is natural Their heattrapping abilities keep Earth from being uncomfortably cold However, the amount of greenhouse gases in our atmosphere has increased over the past 150 years as people burn fossil Greenhouse gases are gases in the Earth's atmosphere that produce the greenhouse effect Changes in the concentration of certain greenhouse gases, from human activity (such as burning fossil fuels), increase the risk of global climate change Greenhouse gases include water vapor, carbon dioxide (CO 2 ), methane, nitrous oxide, halogenated They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere The main greenhouse gases are Water vapor Carbon dioxide Methane Ozone Nitrous oxide Chlorofluorocarbons Greenhouse gases are gases that can trap heat Greenhouse Gas Levels In Atmosphere Reach
