Soot, also known as black carbon, is a potent aerosol pollutant that absorbs solar radiation, leading to atmospheric warming. Sulphur hexafluoride (SF6) is a powerful synthetic greenhouse gas with a very high global warming potential, trapping significantly more heat than carbon dioxide. Water vapour is the most abundant and significant greenhouse gas in the atmosphere; it plays a crucial role in the natural greenhouse effect and contributes to atmospheric warming.
