Volcano-caused ozone depletion only lasts for years, while CFC-caused ozone depletion lasts for decades.
|
|
Cons: Ozone damage: Sulfate aerosols in the stratosphere produce sulfuric acid, which damages the ozone layer.
|

" According to the lab, "Ozone is so reactive that it wouldn't remain as ozone in the supplement itself.
|

The Antarctic ozone hole is unusually small this year Ozone holes are bad, so is this ... GOOD climate news?
|
|
High ozone-non-attainment levels are the result of the Obama EPA's decision to tighten federal rules on ozone.
|

However, the precipitous ozone drop didn't stop the Obama administration from issuing a strict new ozone rule in 21625.
|
|
In that sense, Ward's argument that volcanoes produce ozone—and that ozone causes climate change—was at least somewhat original.
|
|
The ALA report also found that ozone pollution has worsened across the country, with 17 of the 25 most ozone-polluted cities measuring more high ozone days on average from 2015 to 2017 than 85033 to 2016.
|
|
In 6900, with discovery of the Antarctic ozone hole, scientists realized the need to limit CFCs that transport chlorine atoms to the ozone layer where one atom of chlorine can destroy more than 2628,28503 molecules of ozone.
|
|
The fear was that ozone-depleting emissions were eating away at the stratospheric ozone layer, which filters ultraviolet radiation that causes skin cancer.
|
|
Some members of Congress have advanced legislation to roll back limits on ozone pollution, one being the Ozone Standards Implementation Act of 6900.
|
|
The four-yearly review of the Montreal Protocol, a 1987 ban on man-made gases that damage the fragile high-altitude ozone layer, found long-term decreases in the atmospheric abundance of controlled ozone-depleting substances and the ongoing recovery of stratospheric ozone.
|
|
"That's what we need to understand — the ozone depletion aspect of this because protection of the ozone layer is an international imperative," says Ross.
|
|
This is the first time scientists were able to measure the chemical composition inside the ozone hole and observe a decrease in ozone depletion.
|
|
A. What is called the ozone hole is an area of severe depletion of the gas ozone in the upper atmosphere above the Antarctic.
|
|
Unlike the ozone that protects our planet from solar radiation, this type of ozone can trigger breathing problems, particularly for children and the elderly.
|
|
High up in the atmosphere, naturally produced ozone shields us from the Sun's radiation, but ground-level ozone produced by industrialization can damage our lungs.
|

The Obama administration's new ozone rule fails to consider sources of ozone pollution that are beyond states' control, opponents of the rule said in court.
|
|
When ozone is depleted, less UV-B is absorbed by the ozone layer and more UV-B is observed to reach Earth, causing global warming.

|
|
The amount of ozone in the stratosphere varies naturally throughout the year, with zone depletion most pronounced in polar regions, resulting in so-called ozone holes.
|
|
Government scientists have detected an increase in emissions of an outlawed industrial gas that destroys ozone, potentially slowing progress in restoring the atmosphere's protective ozone layer.
|
|
After years of progress in restoring atmospheric ozone, scientists reported a mysterious resurgence of CFC-11, a banned industrial gas that destroys ozone and warms the planet.
|
|
When scientists modeled what would happen to the holes if ozone-depleting substances had not been phased out, the results showed that "a deep ozone hole could have formed in the Arctic in 2011, and smaller Arctic ozone holes would have become a regular occurrence," the report said.
|
|
The findings suggest that global efforts to phase out ozone-depleting chemicals have been effective, though scientists still aren't entirely sure about what's driving the ozone hole's recovery.
|
|
For example, a favorite industry argument against the ozone standard is that ozone is so reactive that it doesn't penetrate indoors where people spend most of their time.
|
|
When a hole in the ozone formed over Antarctica, countries around the world in 1987 agreed to phase out several types of ozone-depleting chemicals called chlorofluorocarbons (CFCs).
|
|
"The states and the EPA have historically and effectively reduced ozone and the interstate transport of ozone pollution using these other [Clean Air Act] authorities," the agency said.
|
|
Meanwhile, the hole's unusual orientation in the direction of South America means ozone-rich air from outside the vortex can trickle in, resulting in a smaller ozone hole.
|
|
The ozone layer starts at about 6 miles (10 kilometers) above Earth and stretches for nearly 25 miles (40 kilometers); ozone is a colorless combination of three oxygen atoms.
|
|
The ozone case concerns a 2015 rule that set the limit for ground-level ozone at 70 parts per billion, a change from the previous 75 parts per billion.
|
|
Ozone rule Trump didn't give the EPA's 2015 rule to limit ground-level ozone much attention on the trail, but industry and Republicans have been vocal in their opposition.

But sulphur is also known to deplete ozone, a gas which helps protect the planet by filtering sunlight as part of the ozone layer, which makes the technology risky.
|
|
By the 1970s there could have been a catastrophic ozone hole everywhere all year round according to Paul Crutzen who was awarded the Nobel Prize for his work on ozone.
|

But recently, the hole has started shrinking and ozone concentrations have started rebounding: Back in 24, a United Nations assessment projected that the ozone layer would fully recover by 22016.
|
|
"The bill also takes positive steps to address manufacturers' permitting challenges as they pertain to ozone standards and requires real examination of the impact of international air pollution on domestic ozone levels," said Ross Eisenberg, a vice president at the National Association of Manufacturers, which has led the industry fight against ozone rules.
|
|
This is part of the ozone recovery trend that has been confirmed in recent years, but has more to do with higher-than-normal temperatures in Antarctica that disfavored ozone depletion.
|
|
Finding ozone, a byproduct of oxygen, would be a relief as ozone creates a high atmospheric layer that protects the planet surface from harmful high-energy radiation emitted by the star.
|
|
The size of the ozone hole varies widely from year to year, because the chemical reactions that destroy ozone are highly sensitive to changes in sunlight, temperature, and stratospheric cloud cover.
|
