South Pole’s ozone hole shrinks to smallest since discovery

Their answer is always “the weather” when real world observations become inconvenient.

Nothing Man did made this change. Take note. We’re embarrassingly insignificant, compared to our arrogance and ego.

[2111USMC]

Well I did do a few hits of windowpane in the early 70's.

[Bullish]

But there's no room in the pea-brained climate “scientists” heads to admit they were wrong about this or anything else when it comes to the field of scaring people into communism using hysterical climate hoaxism.

Sure, it's a grammatically crummy run-on sentence but I don't care.

Got to revise those textbooks!

First: CFCs are heavier than air.

Second: the hole is allegedly 3.6 million miles.( Down from 10.3 million square miles. The entire continent of Antarctica is 5.4 million square miles.) Are they saying that the “antarctic ozone hole” was nearly twice the size of the Continent, and now is about 60% the size of the Continent?

[palmer]

The science for CFCs breaking down into chlorine by high energy UV is pretty basic. Also the increase in CFCs is measured. But the idea that CFCs last 100 years, even if true, means that CFCs don’t affect the ozone layer. They are inert and don’t affect anything.

Th sun is far less active right now. These Luddites think man created the ozone hole.

[SunkenCiv]

Thanks fieldmarshaldj.

[palmer]

The sun was relative inactive in 2008-2009 with no big reduction in the hole. That said, an active sun destroys ozone due to the increase in high frequency UV. The sun also creates ozone all the time by low frequency UV.

I think the main solar link is through weather. The stratospheric vortex was stronger starting in the 80's, depleting the ozone. Weakened vortexes this year and 2002 allowed full recovery. The Sudden Stratospheric Warming that weakened the vortex this year is a phenomenon that is primarily solar with feedback from tropospheric weather.

Eliminating the CFCs that were useful & the price was right so they could be replaced with high-priced, sometimes less satisfactory substitutes was the original plan I believe. It hasn’t helped in any real way I can tell. Except to the makers & sellers of the high-priced substitutes,whose bottom line it has helped. The public was generally being lied to all along as this has taken place IMHO.

[CodeToad]

Of course it was. The second we banned CFCs the nightly news stopped reporting the ozone hole.

[CodeToad]

I don’t think something at 100,000+ feet is bothered by polar weather, not to mention the atmospheric ozone is less than 0.0001 percent of the atmosphere. It never was an issue. Never.

[Elsie]

Earth’s ozone layer shields life on the surface from harmful solar radiation, but man-made chlorine compounds that can last in the air for 100 years nibble at the ozone, creating thinning and a gap over the Southern Hemisphere.

NO!!!

Over Antarctica Only!

The penguins suffer so...

[palmer]

Stratospheric ozone is a real thing, what do you mean "never an issue"? Stratospheric ozone peaks about 25 to 30 km at about 5 ppm or 0.0005 percent.

As for the weather, you can argue that the stratospheric polar vortex is weather. It is solar-modulated but also hooked in a feedback loop with tropospheric waves. The vortex speed peaks around 20 km but the winds extend up another 10 km or more.

President Trump fixed the Ozone Hole. Three Cheers!!!

[VeniVidiVici]

The 1987 international Montreal Protocol—the only United Nations treaty ratified by every country on Earth—banned many of the chlorine compounds used in refrigerants and aerosols.

And there you go. Yet another "feel good, spend lots of money treaty" that did not a damn thing.
