Which greenhouse gas has an average lifetime in the atmosphere of a few weeks to thousands of years?
Mekhanik [1.2K]

Due to human activities, the greenhouse gases are the most substantial mediator of the witnessed climate change since the mid-20th century. Globally, the overall emissions of greenhouse gases due to human activities have upsurged by 35 % from 1990 to 2010.  

The concentrations of carbon dioxide and other greenhouse gases in the atmosphere have upsurged since the start of the industrial revolution. Of the greenhouse gases, the fluorinated gases exhibit an average lifetime in the atmosphere of a few weeks to thousands of years.  

The fluorinated gases refer to an array of gases, which comprise fluorine, incorporating perfluorocarbons, hydrofluorocarbons, and sulfur hexafluoride, among other chemicals.  

These gases are discharged due to numerous industrial procedures and household and commercial applications and do not take place naturally. It is at certain instances used as the substitutes for the ozone-depleting components like CFCs.
