Good News: Ozone Hole Continues Shrinking in 2022

The depleted area of the ozone layer over the South Pole was slightly smaller than last year and generally continued the overall shrinking trend of recent years.

Between September 7, 2022, and October 13, 2022, the annual Antarctic ozone hole reached an average area of 23.2 million square kilometers (9.0 million square miles). This depleted area of the ozone layer over the South Pole was slightly smaller than the average for the same period last year. This marks a general continuation of the overall shrinking trend of recent years.

“Over time, steady progress is being made, and the hole is getting smaller,” said Paul Newman, chief scientist for Earth sciences at NASA’s Goddard Space Flight Center. “We see some wavering as weather changes and other factors make the numbers wiggle slightly from day to day and week to week. But overall, we see it decreasing through the past two decades. The elimination of ozone-depleting substances through the Montreal Protocol is shrinking the hole.”

Every September the ozone layer—the portion of the stratosphere that protects our planet from the Sun’s ultraviolet rays—thins to form an “ozone hole” above the South Pole. Each southern winter, chemically active forms of chlorine and bromine in the atmosphere, derived from human-produced compounds, attach to high-altitude polar clouds. The reactive chlorine and bromine then initiate ozone-destroying reactions as the Sun rises at the end of Antarctica’s winter.

At NASA and NOAA, scientists detect and measure the growth and breakup of the ozone hole with instruments aboard the Aura, Suomi NPP, and NOAA-20 satellites. On October 5, 2022, those satellites observed a single-day maximum ozone hole of 26.4 million square kilometers (10.2 million square miles), slightly larger than last year. The map at the top of this page shows the size and shape of the ozone hole over the South Pole on that day.

When the polar sun rises, NOAA scientists also make measurements with a Dobson Spectrophotometer, an optical instrument that records the total amount of ozone between the surface and the edge of space—known as the total column ozone value. Globally, the total column average is about 300 Dobson Units. Scientists recorded a lowest total-column ozone value of 101 Dobson Units over the South Pole on October 3, 2022. At that time, ozone was almost completely absent at altitudes between 14 and 21 kilometers (8 and 13 miles)—a pattern very similar to last year.

Some scientists were concerned about potential stratospheric impacts from the January 2022 eruption of the Hunga Tonga-Hunga Ha‘apai volcano. The 1991 Mount Pinatubo eruption released substantial amounts of sulfur dioxide that amplified ozone layer depletion. However, no direct impacts from Hunga Tonga have been detected in the Antarctic stratospheric data.

Oh, thank goodness.

Now I’ll be able to sleep tonight.

Aliens are stealing the planet’s ozone. I wonder if Hunter Biden is involved?

We should start selling “ozone credits”. Why not?

It worked for those selling “carbon credits”.

A naturally occurring phenomena that fixed itself.

Despite the always wrong expert class blaming it on air conditioning (3rd world got to suffer) and hair spray.

This is a more recent and cogent example of big science doomsday crowd wrong than the ice age fears.

Learned that from the Marines heading off to Vietnam, They’d get drunk, wait for their bud to pass out by the bonfire and “FIRE IN THE HOLE.”...
Danged fun times. So we copied our elders:>)

“The depleted ozone layer”

BS. It has always been there. It has nothing to do with R12
They didn’t even have the technology to measure it. BUT HEY. Don’t let facts get in the way of massive government control over your life.

On a 4.5 billion year old planet we can measure the size of the ozone layer for about 30 years and determine the correct size it should be and determine that people are affecting it. That’s pretty impressive.

in 1540, Captain García López de Cárdenas led a party of Spanish soldiers with Hopi guides to the Grand Canyon.

Upon discovery of this giant HOLE IN THE EARTH, they were shocked! And they soon discovered that it was growing!

They immediately sent word back to the Spanish Viceroy in Mexico City of their devastating new find.

Upon hearing of this calamity, the Viceroy sent an emergency message back to the Spanish Crown in Madrid, via the next gold treasure ship. SOMETHING HAD TO BE DONE!

The Spanish King and his Queen were devastated! They immediately set in motion the power of government to stop this destruction.

They ordered that all waters in the New World and effectively anywhere in the Spanish Empire be Stopped from flowing and draconian restrictions put in place to prevent anyone from ever using any of the rivers and lakes for drinking, cooking or bathing. The first two were difficult, but the third one was fairly easy.

And so, with the foresight of the Spanish Conquistadores, the Spanish royalty and the Power of absolute tyrannical Government, they saved the Earth from total destruction........................................

This was another scam. DuPont owned the expiring patent for R-12 and so the ozone scam came along as they had that patent.

Yep, everything with the environment happens, because somebody makes a lot of money on it.

Dupont has the patent for newer R-134a that does not do as good a job as R-12

Just like electric cars are being forced on us. Not by far as good as gas cars.
