Emissions of banned ozone-eating chemical rise mysteriously

"SNIP........

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.

When a hole in the ozone formed over Antarctica, countries around the world in 1987 agreed to phase out several types of ozone-depleting chemicals called chlorofluorocarbons (CFCs). Production was banned, emissions fell and the hole slowly shrank.

But starting in 2013, emissions of the second most common kind started rising, according to a study in Wednesday's journal Nature. The chemical, called CFC11, was used for making foam, degreasing stains and for refrigeration.

"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.

No other large nation would profit from it. They have plans for the north passage and the arctic. They want this.
