2019 ozone hole 'smallest in three decades'

Recommended Posts

Still Waters

The ozone hole over Antarctica this year could be one of the smallest seen in three decades, say scientists.

Observations of the gas's depletion high in the atmosphere demonstrate that it hasn't opened up in 2019 in the way it normally does.

The EU's Copernicus Atmosphere Monitoring Service (CAMS) says it's currently well under half the area usually seen in mid-September.

The hole is also off-centre and far from the pole, the EU agency adds.

CAMS' experts, who are based in Reading, UK, are projecting stable levels of ozone or a modest increase in the coming days.

? Good new maybe..

Or it's just doing something weird that we don't understand . It's odd for the hole to move.

Maybe all the small steps every country makes each year is starting to have an effect.

It appears that in the case of CFCs, we are actually making progress.  tmcom is lucky.  That ozone hole has already affected his mind.

The diminishing ozone hole is a success story about what humans can do to change their habits.

At that time I was a process engineer working for a large manufacturing corporation.  The US Government announced an increasing tax then elimination of CFC's  over a several year time frame.  Nothing gets the attention of a business as fast as money, either making it or worse yet losing it.  Two other engineers and I were put on the project of finding replacements for all of the CFC products we used and it amounted to a couple hundred thousand pounds a year in our biggest plants.  It took nearly two years to find and qualify replacements or in some cases actually change the manufacturing process when there was no replacement.   

It saved the company a good deal of money and during the course of the effort we eliminated a 30 year old process that we didn't even need any more but just kept doing because we always had.
