Researchers say that they have pinpointed the major sources of a mysterious recent rise in a dangerous, ozone-destroying chemical.
CFC-11 was primarily used for home insulation but global production was due to be phased out in 2010.
But scientists have seen a big slowdown in the rate of depletion over the past six years.
This new study says this is mostly being caused by new gas production in eastern provinces of China.
CFC-11 is also known as trichlorofluoromethane, and is one of a number of chloroflurocarbon (CFC) chemicals that were initially developed as refrigerants during the 1930s.
However, it took many decades for scientists to discover that when CFCs break down in the atmosphere, they release chlorine atoms that are able to rapidly destroy the ozone layer which protects us from ultraviolet light. A gaping hole in the ozone layer over Antarctica was discovered in the mid 1980s.
The international community agreed the Montreal Protocol in 1987, which banned most of the offending chemicals. Recent research suggests that the hole in the Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s.
When was the CFC problem discovered?
CFC-11 was the second most abundant CFCs and was initially seen to be declining as expected.
However in 2018 a team of researchers monitoring the atmosphere found that the rate of decline had slowed by about 50% after 2012.

There’s one in the North as well...............
CFCs as refrigerants seemed to be considered bad mainly because they were cheap, effective, & widely available. They said CFCs were depleting the ozone layer. It’s my understanding that the ozone layer is self-replenishing. People in charge of such things wouldn’t lie to us, now would they? Seems to me that a lot of this stuff leads right back to the old saying that says...”follow the money”.
” China is a developing country, and has committed to review its emissions and climate obligations sometime around 2030!”
I thought they’ve said that there would be cats and dogs living together and mass hysteria by then?
Environmentalists are such phonies (even if you agree with their view point) . It’s not western countries causing all the pollution. It’s China and India. They should get slapped with tariffs until they get up to code.
“Was there ever a time when there wasnt one?”
This was debunked decades ago. The ozone hole expands and contracts on its own schedule. The “scientists” discovered it in an expanding phase, and decided something was destroying the ozone.
Climate science news is difficult to know what is real science, propaganda or honest naive attempts to begin to understand a very complex thing and failing. Thanks for the correction
You were spot on with the kind of crap the UN pulls that is, how it benefits socialist nations over capitalist nations. Why are we still in the UN and why is the UN still in America ??
Clinton? More. Hes the responsible party. The adult in the room.
Why? Because according to the Paris accords, China is a developing country, and has committed to review its emissions and climate obligations sometime around 2030!
This is the main fact being covered up by the Goebbels Warming people, that the 2 biggest "greenhouse gas" producers, India and China, won't do ANYTHING for AT LEAST 12 years and then, after the 12 years, we have to trust them... which we can't.
Are our “negotiators” zealots who will take any sort of CO2 reduction as great, or blind, or just bribed?

Religious zealots who see the element carbon as the work of the devil (aka white male patriarchy).
Surprise!
R-11 was used also to make meth in the old days. They are flooding us with fentanyl, maybe much of Asias meth habit is being fueled by China as well.
China cheating? OMG it can’t be ... I’m shocked I tell you - shocked.
The left just got real mum can’t blame the USA.
They just haven’t figured out how to do it yet...................
As a scientist, hearing about them, and about asbestos handling, and about the climate fervor, the whole of it makes me want to retch.
In this particular matter, iI suspect China is probably acting realistically to provide things for their citizens that are economically beneficial and safe. (Not in huge favor of them for trying to destroy our way of life, tho')
Some things hove no answers they just found it out confused and with much anger.
