Something strange is happening with a now-banned chemical that eats away at
Earth's protective ozone layer: Scientists say there's more of it - not less -
going into the atmosphere and they don't know where it is coming from.
[...]
"It's the most surprising and unexpected observation I've made in my 27 years"
of measurements, said study lead author Stephen Montzka, a research chemist at
the National Oceanic and Atmospheric Administration.
"Emissions today are about the same as it was nearly 20 years ago," he said.
Countries have reported close to zero production of the chemical since 2006 but
the study found about 13,000 tonnes (14,300 tons) a year has been released
since 2013. Some seeps out of foam and buildings and machines, but scientists
say what they're seeing is much more than that.
Measurements from a dozen monitors around the world suggest the emissions are
coming from somewhere around China, Mongolia and the Koreas, according to the
study.

I'm putting my money on Mongolia.
