Greenhouse Gases Carbon Dioxide (CO 2) Methane (CH 4) Nitrous Oxide (N 2 O) Fluorinated GHGs NOAA's Annual Greenhouse Gas Index (AGGI) is a yearly report on the combined influence of longlived greenhouse gases (atmospheric gases that absorb and radiate heat) on Earth's surface temperature The index compares the combined warming influence of these gases each year to The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space The gases that contribute to the greenhouse effect include water vapor, The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth's atmosphereGreenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated g...
