Carbon dioxide, methane, and water vapour are the most important greenhouse gases. (To a lesser extent, surface-level ozone, nitrous oxides, and fluorinated gases also trap infrared radiation.) In general, greenhouse gas concentrations have been particularly high during warm periods and low during cold periods.
