    Why the Ozone Hole Is on Track to Be Healed by Mid-Century

    Why the Ozone Hole Is on Track to Be Healed by Mid-Century - Recent UN data shows that 99 percent of ozone-destroying chemicals have been phased out, underscoring a hopeful environmental story.

    In 1985, atmospheric scientists in Antarctica noticed something troubling. For decades, they’d been measuring the thickness of the ozone layer in the upper atmosphere, the layer of gas that deflects much of the sun’s radiation. Starting in the 1970s, it had started plummeting. By the mid-1980s, they observed that it was on track to be wiped out in the next few decades.

    Their discovery was cause for worldwide alarm and unprecedented action. In short order, the international community marshaled its resources — scientific, economic, diplomatic — to mount a campaign to ban the chemical that caused the damage, chlorofluorocarbons (CFCs), and to restore the ozone layer.

    Fast-forward to today: The ozone is on the path to recovery, ifnot fully restored.A report released by the UN on January 9, 2023, found that the ozone layer is on track to recover within four decades.Thanks to the most effective international environmental treaty ever implemented, nearly 99 percent of banned ozone-depleting chemicals like CFCs have been successfully phased out. Should those policies remain in place, the report finds that the ozone layer is projected to return to its 1980 levels by 2040 as a global average, with thinner Arctic ozone recovering by 2045 and Antarctic ozone — the area where scientists first discovered a hole — recovering by 2066.

    So are we to think that there was never holes in the ozone layer in all of our historical warming trends.
    Or does this story just carry too much value as "man is the cause of global warming and we can fix it" to be corrected.

    Because the weather patterns over Antarctica could not have anything to do with it. Right?

    Just asking for a curious friend.

    National Geographic ran a special a few years back saying holes in the ozone layer had likely occurred throughout history, maybe as a result of volcanic ash in the atmosphere.

    There's no question that we're not spewing nearly the carbon into the air today to match the volcanoes of the past.

    Plus, I think you're on to something about the weather patterns-- doesn't the Ozone hole open more in spring and close in fall/winter?

    Hard to determine if any changes made make any difference at all since the historical record only goes back to the 70s. Correlation does not imply causation.
    When Donald Trump said to protest “peacefully”, he meant violence.

    When he told protesters to “go home”, he meant stay for an insurrection.

    And when he told Brad Raffensperger to implement “whatever the correct legal remedy is”, he meant fraud.

    War is peace.

    Freedom is slavery.

    Ignorance is strength.

    In this case they are blaming Chlorine instead of carbon. I'm cool with reducing pollution when we can but concerned with it being used as a political weapon.

    I agree, we've learned to pollute a lot less, and that has its own rewards, but we're also seeing a tiny fraction of the volcanoes earth used to see.

    And, ozone holes come and go.

    We're still going to see a lot of harmful fallout from the massive "renewable" push. Too many coal-fired plants have been shuttered and blackouts are becoming common.

    I have to wonder if some of the fallout isn't intended by the WEF, however. Schwab has been pretty vocal and upfront about the need level the wealth field between first-world and third-world nations. Renewable energy is starting to do just that.

    Very interesting how Ozone depletion along with Acid Rain went off the environmentalist radar. Just keep shifting the narrative as long as it can be used for an anti-industrial anti-capitalism message.

    CO2 doesn't cause the ozone hole. Other chemicals do- volcanoes are a problem. But CFCs were too. An actual real pollution issue that we solved.
