Detailed explanation-1: -Methane (CH4) is a hydrocarbon that is a primary component of natural gas. Methane is also a greenhouse gas (GHG), so its presence in the atmosphere affects the earth’s temperature and climate system.

Detailed explanation-2: -It absorbs longer wavelengths of the electromagnetic spectrum while transmitting shorter wavelengths. It absorbs shorter wavelengths of the electromagnetic spectrum while transmitting longer wavelengths.

Detailed explanation-3: -The main greenhouse gases whose concentrations are rising are carbon dioxide, methane, nitrous oxide, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs) and ozone in the lower atmosphere.

Detailed explanation-4: -hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) sulphur hexafluoride (SF6) nitrogen trifluoride (NF3) 10-Nov-2016

Detailed explanation-5: -Carbon dioxide (CO2) Methane. Nitrous oxide. Water vapour.
