摘要: GHGs can be subdivided into two groups: those present in the atmosphere since before industrial revolution and that are chemical compounds created produced by humans. The first group includes carbon dioxide (CO2), methane (CH4) nitrous oxide (N2O), whose concentrations have been rising as a consequence of intensification human activity. second perfluorocarbons (PFCs), chlorofluorocarbons (CFCs), hydrofluorcarbons (HFCs), hydrofluorchlorocarbons (HCFCs) sulfur hexafluoride (SF6). Each these gases has different potential to absorb infrared radiation.
