The Montreal Protocol of 1987 reined in releases of ozone-devouring manmade chemicals containing chlorine and bromine, and some researchers have predicted that the protective shield will rebound by mid-century.
But the Boulder-led team found large, nitric acid-containing particles that could delay the recovery and make the ozone layers over both poles more vulnerable to climate change, said atmospheric chemist David Fahey of ...
