Detailed explanation-1: -Major greenhouse gases include carbon dioxide, methane, nitrous oxide, and various synthetic chemicals. Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities.

Detailed explanation-2: -The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which are all natural compounds), and fluorinated gases (which are synthetic or man-made).

Detailed explanation-3: -“Air pollution in the form of carbon dioxide and methane raises the earth’s temperature, ” Walke says.

Detailed explanation-4: -The Earth has a natural greenhouse effect due to trace amounts of water vapour (H2O), carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) in the atmosphere.

Detailed explanation-5: -hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) sulphur hexafluoride (SF6) nitrogen trifluoride (NF3) 10-Nov-2016
