Title: New Ozone Scare
Post by lee on Dec 25th, 2018 at 10:23pm

Quote:
Earlier this year, the United Nations announced some much-needed, positive news about the environment: The ozone layer, which shields the Earth from the sun’s harmful ultraviolet radiation, and which was severely depleted by decades of human-derived, ozone-destroying chemicals, is on the road to recovery.

The dramatic turnaround is a direct result of regulations set by the 1987 Montreal Protocol, a global treaty under which nearly every country in the world, including the United States, successfully acted to ban the production of chlorofluorocarbons (CFCs), the main agents of ozone depletion. As a result of this sustained international effort, the United Nations projects that the ozone layer is likely to completely heal by around the middle of the century.

But a new MIT study, published in Nature Geoscience, identifies another threat to the ozone layer’s recovery: chloroform — a colorless, sweet-smelling compound that is primarily used in the manufacturing of products such as Teflon and various refrigerants. The researchers found that between 2010 and 2015, emissions and concentrations of chloroform in the global atmosphere have increased significantly.

"The ozone hole that forms in the upper atmosphere over Antarctica each September was slightly above average size in 2018, according to NOAA and NASA scientists."

"According to the report, this year’s ozone hole reached an average area coverage of 8.83 million square miles (22.9 square km), almost three times the size of the contiguous United States. It ranks 13th largest out of 40 years of NASA satellite observations."

It has been disappearing? Now it is doomed.

There's a hole in your bucket dear Liza, dear Liza.

Anyone notice that there is 'half' the air in the atmosphere compared to the period before the 'rape of the planet'.

Ozone hole 13 Oct 2018 – 22.9M km2
Ozone hole 13 Oct 1996 – 22.8M km2

No statistical difference.

Maybe we are doomed?

Is it the End Times?

Responses that occur on polar stratospheric mists (PSCs) assume an imperative job in improving ozone exhaustion. PSCs shape all the more promptly in the outrageous cold of the Arctic and Antarctic stratosphere. This is the reason ozone gaps originally framed, and are more profound, over Antarctica.
