Banned Ozone-Destroying Chemicals Still In Production, Scientists Baffled

The Guardian reports that if these emissions are left unchecked, it could tack an extra decade onto restoration of the all-important ozone layer, which protects the earth from the sun's damaging UV radiation.

However, a study recently published in Nature reveals that CFC-11 production may be happening somewhere in the world despite the Montreal Protocol. It is only destroyed in the stratosphere, some 9 to 18 miles above the planet's surface, where the resulting chlorine molecules engage in a string of ozone-destroying chemical reactions.

Somebody's cheating. There's some slight possibility there's an unintentional release, but. they make it clear there's strong evidence this is actually being produced. Movement of gases around the atmosphere, the destruction of buildings harboring CFCs from the 1970s and the failure to capture the chemical during the production of other chemicals could all lead to a rise in CFC-11, but not almost enough to explain the results. CFC-11 was originally used as a refrigerant but was banned in 1987 under the Montreal Protocol, the worldwide agreement created to protect the ozone layer.

The amount of trichlorofluoromethane (CFC-11) in the atmosphere has been sinking more slowly since 2012 than should be expected, scientists at the National Oceanic and Atmospheric Administration in Colorado wrote.

To put that in perspective, production of CFC-11, marketed under the trade name Freon, peaked at about 430,000 tons per year in the 1980s. Reports past year indicated that production of new chlorine containing chemicals could cause significant delay. However, in 1987, an worldwide team of scientists proved that the emissions of such chemicals were actually harming the environment, particularly the ozone layer.

Preparations for controversial USA embassy move in Israel underway
Israel claims all of Jerusalem as its "eternal and undivided" capital which it captured from Jordan in the Six Day War in 1967. Other U.S. presidents have promised the embassy move but never acted on it because of its politically charged symbolism.

The UN Environment said: "The Scientific Assessment Panel of the Montreal Protocol, which includes the authors of the report, will finalise its quadrennial assessment by the end of the year and we expect these findings to be presented to the parties to the Montreal Protocol, who will carefully review and address them". "It is therefore, critical that we take stock of this science, identify the causes of these emissions and take necessary action".

"It really looks like somebody is making it new" in violation of global law, says Montzka.

"This treaty can not afford not to follow its tradition and keep its compliance record", he said. "They should tell the industries that's not going to work". But the apparent increase in emissions of CFC-11 has slowed the rate of decrease by about 22 percent, the scientists found.

"Knowing how much time and effort and resources have gone into healing the ozone layer, and to see this is a shocker, frankly", said Montzka.

David Doniger, director of the climate and clean energy program of the Natural Resources Defense Council, an environmental group in Washington, said the new emissions were "bad for the ozone layer and bad for climate change".
