WebIn our work on CO 2 and Greenhouse Gases, we know that global emissions of carbon dioxide, methane, nitrous oxide and other gases have increased rapidly over the past century, and particularly over the last 50 years. We would expect that these emissions have changed the concentration of these gases in the atmosphere. WebThe atmospheric concentrations of long lasting greenhouse gases like methane (CH 4 ), carbon dioxide (CO 2 ), chlorofluorocarbons (CFCs), nitrous oxide (N 2 O), and …

Webgreenhouse gases due to their very high global warming potentials and long atmospheric lifetimes even if they only exist at a few ppt (see table). Ozone is also a greenhouse gas, but it differs from other greenhouse gases in several ways. The effects of ozone depend on its altitude, or where the gas is located vertically in the atmosphere.
A greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy at thermal infrared wavelengths, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3).
