Ozone depletion

It is one of four man-made chemicals newly discovered in the atmosphere by a team at the University of East Anglia. But CFC-113a is the only known CFC whose abundance in the atmosphere is still growing. CFC-113a seems to have been accumulating unabated since 1960. Its source remains uncertain, but production of hydrofluorocarbons in East Asia is suspected by some. Between 2012 and 2017, concentrations of the gas jumped by 40 percent.[3][4][5]
