emissions contribute to global climate change?
The cause of climate change is dynamic processes on the Earth, external influences such as fluctuations in the intensity of solar radiation, and, more recently, human activities. Changes in the current climate (in the direction of warming) are called global warming. Emissions are just one of the points by which a person influences climate change.

SF6 is the most highly potent greenhouse gas known to-date. Over a 100-year period, SF6 is 23,900 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is also a very stable chemical, with an atmospheric lifetime of 3,200 years. As the gas is emitted, it accumulates in the atmosphere in an essentially un-degraded state for many centuries. Thus, a relatively small amount of SF6 can have a significant impact on global climate change.
